Experience: A Philosophical View

Antonio López

The philosophical account of experience presented here considers this ‘most deceitful’ (Whitehead 1959: 16) and ‘obscure’ (Gadamer 1998: 346) word as an epistemological category, that is, as integral to our access to truth in both its gnoseological and ontological dimensions. Experience, in this sense, is the practical or speculative knowledge that emerges in time as the fruit of the eventful engagement of all of ourselves with others, the world, and, ultimately, God. While less directly existential than descriptive elucidations of experience that emphasize the affective and sensorial resonance of what the subject lives and undergoes, the philosophical approach grants better grasp of the way experience contributes to the building of different worldviews within which people understand and order human life. The polysemic and ubiquitous character of experience, while forestalling a univocal and all-encompassing narrative, does not prevent us from discovering threads tying various discourses on experience together. It also does not hinder the recognition of the essential elements that constitute every human experience of the engagement of the whole person with all of reality.

The entry begins by examining the etymology of experience to show the original richness and permanent complexity of this term. Without the claim of being exhaustive, the following study keeps a speculative emphasis and illustrates some key shifts of meaning that occurred during the historical unfolding of Western culture. It first shows the early Greek understanding of experience as a kind of knowledge and its deepening enabled by the Christian perception of reality as created from nothing by a transcendent God. It then suggests that, in the course of its historical development, the concept of experience undergoes a threefold conceptual reversal. During the long centuries of modernity, experience is no longer seen as a type of knowledge but as its very form. Experience is then conceived mostly as an experiment carried out by the human subject who has the measure of truth within. Finally, more recent attempts conceive experience as the living out of human historical finitude and seek to avoid the interpretative control of subjectivity.

Although it does not deal directly with religious or Christian experience, this philosophical elucidation explores the intrinsic relation between reality, God, and our knowledge of both. Furthermore, without absorbing theology into philosophy, it also integrates significant elements of Christian revelation. This philosophical view on experience thus sets the foundation for an exploration of Christian experience that is carried out elsewhere.

1 Etymology

Both the Latin experientia and the Greek ἐμπειρία (empeiria), from which the English term experience derives via the French expérience, originate from two different yet homophonous Indo-European verbal roots. The first root, ‘per-2: E. per-’, means ‘to try, to dare, to risk, danger’ (Pokorny 2007: 818). From this root comes the Greek πεῖρα and πειράω (peira and peirao: attempt, experiment, tempt, trial completed, projected undertaking) and ἐμπειρία, as well as the Latin verb perior* (to try, to attempt), the derivatives peritus (one who has the experience of something or is capable of something), periculum (trial, risk, danger), and the noun experientia (Thesaurus linguae latinae 10:1:1500). The second root, ‘per-2: B. per-, perə-’, means ‘to carry over, bring, to go over, fare’ (Pokorny 2007: 816–817). From this second root stems, among others, the Greek terms πείρω (peiro: to go from one part to the other), περάω (perao: to go through), and πἐρας (peras: limit, end, realization) (Chantraine 1999: 870); Latin terms such as portus (harbour), porta (portal, gate), and porticus (colonnade) (Ernout and Meillet 2001: 498–499); and the German fahren (travel). The German erfahren (to come to know, to learn through travelling) and Erfahrung (experience) derive from fahren. Walter Belardi suggests that a certain relation connects these two senses since they could be independent developments of a remote verbal root per-, ‘to traverse risking and trying’, from which other different meanings come (2002: 52). Etymologically, therefore, the term experience has a twofold connotation: (1) an activity seen as an attempt, a trial, or the outcome of trying over time, and (2) to pierce through, to risk going through, or to cross at one’s own risk.

2 Experience: a way of knowing

Considering the philosophical meaning of experience in light of its etymology, experience may be viewed as a specific kind of knowledge that emerges as the fruit of our eventful engagement with others, the world, and the ultimate principle that accounts for all that is and which we normally call God. As a verb, experience entails the act in which all of the human being (body, soul, and spirit) is involved with the world and others in the pursuit of knowledge all the way through to the ultimate principle, thereby putting oneself at risk – that is, growing (or not) as a person. This action requires the intrinsic openness of finite beings to a perfection that cannot come to be without the person’s involvement. As a noun, experience refers to a specific knowledge, the method that brings a person to it, and the person’s awareness of both. Before modernity’s arrival, experience mostly meant one of the ways of knowing. This section first explores its meaning in the early Greeks and then examines its Christian transformation.

2.1 The Greek approach

For the early Greeks, experience is a knowledge elicited by personal practice. It is a trying and a going through that yields a specific learning. In the Odyssey, for example, we read that Halitherses can explain to Telemachus that the two eagles wheeling and circling above them is a good omen because he does not prophesy ‘without experience’ (ἀπείρητος, apeiretos) (Odyssey 2.170; Homer 1999: 43). Plato, instead, considers that a good judge should be guided by science (ἐπιστήμη, episteme), not by ‘personal experience’ (empeiria). The good judge, says Plato, should know the nature of evil not by having experienced it personally – this would be a limited knowledge of justice – but by having studied and observed it in others (Republic 409b–c; Plato 2007: 102–103). Aristotle argues that it is through experience, generated by memory (Metaphysics [Met.] 980b 28; Aristotle 2002: 1), that art (τέχνη, techne) and science (episteme) come to be (Met. 981a 5–7; Aristotle 2002: 1). The experienced man, although less wise than the artisan, the craftsman, and the one with theoretical competence, is wiser than the one who only has sensation (αἴσθησις, aísthēsis). Even though only the knowledge of ‘primary causes and principles’ grants episteme, the experienced man does possess a practical science (empeiria) (Met. 981b 30–982a 1; Aristotle 2002: 3). For Aristotle, empeiria is the knowledge of the particular, but it does not know the universals; the material, formal, final, and efficient causes; and why things are (Met. 981a 28–30; Aristotle 2002: 3). Experience is a technical mastery and practical wisdom gained from living – often through risking and probing – that episteme needs since it contributes evidence to understanding.

Even though there is a common agreement amongst the Greeks, there is a still a significant difference: whereas for Plato the theoretical dimension of knowledge – which consists in the contemplation of the world of ideas (Phaedo 79d; Plato 2001: 277) – and the practical dimension – which deals among other things with political virtue (Republic Book 6; Plato 2007) – are coextensive, for Aristotle there is a more pronounced distinction between these two. Since experience does not offer the universal and causal knowledge that accounts for what and why things are what they are, it occupies an inferior rank to wisdom.

For the Latins, the Greek distinction between episteme as science in the strict sense and empeiria as the beginning of the pursuit of wisdom became clear some time later. As Belardi shows, Cicero translated empeiria with scientia, not experientia (De finibus 4.14). It was Varro who first adopted the term experientia to mean experimentation (De re rustica 1.40.2) and Lucretius who indicated knowledge that comes from practice (De rerum natura 5.1452) (Belardi 2002: 25, 34). The Latin authors, having only one term available to refer to science (scientia) and not two (empeiria, episteme), would need to adjectivize science as practical or theoretical to specify which one was meant. Nevertheless, even with their own internal distinctions, the Greek and Latin mindsets were speculative and concrete, not technological and abstract like the modern and postmodern worldviews – in which science is commonly taken to mean the systematic learning about the natural world by means of empirical methods, distinction is separation (Schindler 2011: 350–382), and experience is experiment.

The Platonic and Aristotelian categorizations of the degrees of knowledge, of which empeiria is the second, rests on their accounts of the relation between the eternal, unified, and ordered cosmos and the first principle (God). Finite beings, or ‘becomings’ as Plato calls them, possess a rich ontological structure. They are not, as we tend to think nowadays, neutral material open to manipulation. Key principles, such as form and matter and act and potency, account for what they are. For Aristotle, ‘form’ is the principle of intelligibility present in the particular and, unlike Plato, only separate in notion. Form allows everything to be what it is, and in its light, all the other metaphysical principles can be understood. The form ‘horse’ accounts for both a specific living horse (say Bucephalus, Alexander III’s horse) and for its being a horse (not another type of animal). Hence form, present in the actual being, accounts for the horse’s enjoying its own being-in-itself for as long as it lives: growing, galloping, grazing, mating, playing, etc. (its entelecheia; Met. 9.1047a 30; Aristotle 2002: 171). Matter is that which underlines the form of a particular thing, a potency straining towards form (Physics 2.192a 18–19; 214a 13–16; Aristotle 2008: 45, 109). Actuality (energeia) regards the fullness of being what one is. Energeia is ontologically prior to potency. Potency, rather than a possibility to be actualized, indicates both the limiting of a form and the capacity to live up to that form without being able to identify fully with the form (Met. 5.1019a 15–1020a 7; Aristotle 2002: 93–94). The priority of act also entails that motion is a peculiar kind of actuality, that is, the actuality of a potency qua potency (dynamis; Physics 2.201a 10; Aristotle 2008: 74; Barnes 2001). Motion, or change, includes a variety of realities: the coming to be and ceasing to be of something, the student’s acquisition of wisdom, a tomato’s ripening, topographical change, etc. Rest, in this view, is a perfection, not idleness or the absence of change. The concept of nature (physis), in fact, meant ‘a certain source and cause of being moved and of coming to rest in that to which it belongs primarily’ (Physics 2.192b 22–24; Aristotle 2008: 50).

The concrete existence and liveliness of the eternal and unified cosmos that encompasses all existing beings requires a first principle to account for the whole as we experience it. For Plato, the first principle was the Good, inseparable from the world of the Ideas whose copies were inserted into their recipients by a Demiurge who thus allows finite beings to come to be. Later Platonists developed Plato’s thought further. Especially important for his reception by both pagan and Christian thinkers alike was the third-century so-called ‘Neoplatonist’ Plotinus, who took a more distinctly monotheistic view. For Plotinus, the first principle was the One that, being the most perfect, ineffably gives what it is not (Enneads 5.1–2, Plotinus 1984: 11–65; Perl 2014: 107–149). For Aristotle, the self-thinking thought (the unmoved mover) is the guarantor that there has always been and will always be forms and order in the unified cosmos. Unlike for Plato and Plotinus, Aristotle’s unmoved mover does not give. It instead moves the cosmos by being loved. It alone eternally enjoys the best life, self-thinking thought, while we only at times and very briefly experience the delight of contemplation and thought (Met., 12.1072b 15–28; Aristotle 2002: 241–242).

Looking back at these Greek authors from a Christian perspective – with its doctrine of creation from nothing (creatio ex nihilo) and the revelation of God’s simple and eternal unity as a Triune communion of persons – we can see that, although leading in a certain extent towards it, Greek thought was unfamiliar with the radical conception of divine transcendence that characterizes Christianity. Plato’s Good, although separated by an abyss from finite beings, does not exist independently of them. Aristotle’s self-thinking thought (regardless of whether it is aware of it or not) shares a necessary existence with those finite beings that never fully reach the unmoved mover and that imitate it either through eternal circular movement or through continual reproduction. Plotinus’ thought on the One and its mysterious relation with the other two hypostases, Spirit (nous) and Soul (pneuma), is very complex. Yet, it can be affirmed that, despite its radical and immaterial otherness and due precisely to its incomparable perfection, the other two hypostases cannot not be (Enneads 5, Plotinus 1984; Enneads 6.9, Plotinus 1988: 299–345).

Within such a cosmos, human beings are by nature defined by a desire to know (Met. 1.980a 21; Aristotle 2002: 2). Being able to contemplate in amazement the beauty and truth of the cosmos is thus not just simply one activity among many others (Theaetetus 155d; Plato 2002: 54). It instead is what fulfils a human being’s telos. Thus, along with its sense as a kind of knowledge, experience also regards the risk of living out one’s own form and of being educated into it; education, in fact, was the Greeks’ predominant concern (Jaeger 1986: xxiii [vol. 1]). The experience of being human is to seek the joyful and peaceful contemplation of the ultimate reasons for whatever is and becomes, and for the social and cosmic order within which limited beings belong and live together.

The search for the ultimate principle that accounts for human experience, however, is rather difficult to live out for both philosophical and existential reasons. Plato recognizes that ‘the father and maker of all this universe it is a hard task to find; and even if we found him, to tell of him to all men would be impossible’ (Timaeus 28C; Plato 2005: 51). Among others, Aeschylus’ Oresteia (1992) and Hesiod’s Theogony (2010) are unforgettable witnesses that the presence of evil, the ongoing political and national struggles, and the tragic relationship between gods and mortals makes human existence arduous. Yet, part of the greatness of the Greek culture is that its faithfulness to the encounter with the world brought the Greeks to acknowledge an openness to an unpredictable divine assistance. Plato, in a key passage that captures many of the connotations of experience indicated thus far, gives full expression to this expectancy:

And yet he is a weakling who does not test in every way what is said about them and persevere until he is worn out by studying them on every side. For he must do one of two things: either he must learn or discover the truth about these matters, or, if that is impossible, he must take whatever human doctrine is best and embarking upon it as upon a raft, sail upon it through life in the midst of dangers, unless he can sail upon some stronger vessel, some divine revelation, and make his voyage more safely and securely. (Phaedo 85c–d; Plato 2001: 297)

2.2 Christian deepening

Ancient Christian thinkers such as the Cappadocian Fathers and Augustine of Hippo both adapted and corrected Platonic and Neoplatonic thought. Yet, a full articulation of the philosophical view of experience was achieved, in dialogue with Aristotle’s thought, in the thirteenth century by Thomas Aquinas. Although it would be possible to draw from many authors, for our purposes it suffices here to present Aquinas’ thought.

Aquinas’ epistemic use of experience is very similar to Aristotle’s: experience is a sensory mode of knowing (Summa Theologiae [ST] I–II, q.15 a. 1; 1920: 86–87) that apprehends finite beings (ST I, q.54, a. 5; 1920: 276–277), that is both learnt over time (ST I, q.58, a. 3, ad 3; 1920: 290) through the accumulation of memories (ST I, q.64, a. 1, ad 5; 1920: 320) and ordered to practical wisdom (ST II–II, q.49, a. 3; 1920: 1397). He also argues for experience as a certain way of knowing by connaturality (ST II–II, q.45, a. 2; 1920: 1374). Nevertheless, his epochal re-elaboration of Aristotelian metaphysical principles in light of the revealed doctrine of creation from nothing – that is, as utterly dependent on a good, omnipotent, and provident God – is key for adequately articulating the experience of the encounter with the world, others, and God (Gen 1–3; Ps 148; Isa 66:1–2; 2 Macc 7:28; John 1:3; Col 1:16; Rev 4:11). As will become clear in what follows, a metaphysical ground like this one is needed to prevent experience from being reduced to a subjective expression of one’s own emotions or intellectual faculties.

Aquinas shows that, unlike what Aristotle considered, the polarity of form and matter and act and potency is not ultimate but needs to be integrated with the esse (being) that is common (esse commune) to every finite being. Particular beings are constituted by the ontological unity of esse and essence (itself the unity of matter and form). If, for Aristotle, form accounted for both what a particular thing is and its existing (entelecheia), the recognition that the world is created helps us realize that form is not the ultimate ground of the latter (esse). Aquinas explains that whereas form grants the intelligibility of a particular being (it allows us to see that this is a horse), esse gives it to its actuality (this is a horse). Form is no longer the highest principle of actuality; it is esse. For Aquinas, form is indeed responsible for esse at the level of the substance, but form can give esse to matter (and hence account for substance) because form has ‘received’ esse (ST I, q.4, a. 1, ad 3; 1920: 21; De potentia Dei q.3, a. 4, ad 7; 1920: 105). Form still keeps its necessity, but it no longer has in itself the necessity of its own being. When thinking of the relationship between esse and what something is (essence) in that which is (ens, the existing being), form is seen as a certain potency that, without being matter, receives esse, which is an act that is not a form. Form, without becoming matter, ‘receives’ the esse that it communicates to the matter with which it is one (Summa Contra Gentiles 2, c.54, 5–6; Aquinas 1975: 157; Gilson 1994: 114–123). Esse is neither its form nor its matter but something else, an ‘other’ (aliud) that comes to the thing by means of its form (De substantiis separatis 6). Esse, for Aquinas, is not simply the existence of something whose concept, as Kant thought, would be complete in itself (the existence of a note of fifty sterling pounds, albeit relevant for our wallet, does not add anything to its concept). Rather, esse (being) is ‘the perfection of all perfections and the act of all acts’ (DPD q.7, a 2, ad 9; 1920: 12–13). Esse, we could say, gives to form the act of being, and form determines the very act that makes it be in the essential order. Thus, finite and material created realities are the unity of matter and form, esse and essence (known as the ‘real distinction’; De veritate q.27, a. 1, ad 8; 1994: 311–312), and esse and ens (between which there is an ontological difference). It is the relative priority of esse over essence (neither of which exists without the other) that preserves and deepens the priority of act over potency. Contemplation of finite beings in their creative newness allows human beings to experience not so much the Aristotelian ‘amazement’ before what is, but ‘wonder’ before the miracle that something finite exists at all (Balthasar 1991: 613–627).

Like it was for the Greeks, the metaphysical constitution of finite beings is justified by a correspondent account of the divine being. For Aquinas, God is the simple, perfect, and self-subsisting being whose essence is his esse (ST 14.2; 1920: 73–74). Created being, unlike God’s being, is perfect and simple but not self-subsistent (DPD 1.1; 1920: 4–5). God is radically other from the world. Yet, since he shares his being with the finite cosmos without losing himself, God, as Augustine famously wrote, ‘is higher than my highest and more inward than my innermost self’ (Confessions 3.6.11; 2018b: 82–83). The similarity within a greater dissimilarity between God and the created world allows for an analogical – not univocal or equivocal – relation between God and the world that deepens and fulfils experience as the Greeks understood it. The novelty may be clarified in three key and interdependent elements.

First, drawing from the work of several recent Catholic and Protestant authors (Schmitz 1996; Ulrich 2018; Bruaire 1983; Tourpe 2020; Milbank 2003 and 2013, among others), we can say that creation is a communication of being which, looked at from the point of view of the receiver, is best described as gift. Granted that God is simple and that creation is from nothing, both the action (creating) and the beings involved in it (creator and creature) are gift. Created being (esse commune) is divine being given away as other from God (it is non-subsistent). Revisiting Aquinas’ metaphysics of creation in light of this insight, we can say that the very structure of a finite being, in its receiving and communication of esse, of matter and form and esse, is the way in which finite beings enact the gift-character of their created being.

Second, every gift is symbolic. Its logos (reason, form) says first what a finite being is – hence its created form does not lose its onto-logical necessity. Yet, the logos of the gift also reveals the original giver. As the primordial source that continuously grants being, the giver remains interior to the finite gift which remains other from the giver (the divine giver is self-subsistent whereas finite being is not). Finite beings possess their ultimate ground and intelligibility not in themselves but in the transcendent God from which they come.

Third, the creative communication of being is not random because it is given to the human being primordially. The world, in its relation with man, also participates in the gift-character of being. That the human being is gift because he has ‘been given to himself’ presupposes, on the one hand, that the original donation is an act of love (the gift of self to another) and not just the simple diffusiveness of the good, as Plotinus claimed. As Augustine put it, God creates neither out of need (nulla indigentia; Expositions of the Psalms 134.10; 2018a: 226; City of God 11.24; 2012: 24–25) nor out of necessity (nulla necessitate; City of God 11.22; 2012: 21–22) but because he is good (quia bonus) and because he wants to (quia voluit). If it were just because God is good, donation would be the simple communication of the good and we would still not grasp the novelty of creation. If it were only the fruit of God’s volition, donation would not be the analogical participation in God’s being and it would be random. Further, the existence of goodness, freedom, and volition in God means that God is a personal being. The creative gift is the free donation of self to another. Further, it also means that person, not substance like it was for Aristotle, is the highest perfection (ST I, q.29, a. 3; 1920: 157–158). Being the gift of a person to another, the creative gift calls to be received and reciprocated gratis (freely; gratuitously).

The Thomistic retrieval of Aristotle’s metaphysics, grounding itself in Augustine’s appropriation of the Platonic and Neoplatonic tradition as well as in Pseudo-Dionysius’ thought (O'Rourke 2005), deepens and broadens the understanding of experience as the eventful engagement of all of oneself with others, the world, and God. Through this understanding, it becomes clearer why the world is not a necessary emanation or a permanent finitude bereft of a beginning. It also shows why it is good to be even if one is not God. Because of a proper distinction between God and the world, finite beings acquire their contours and proper relationships among the finite beings. The gift-character of being deepens the sensorial and ontological perception of finite beings. Thus, the practical wisdom that experience gathers is informed by divine gratuity which calls for a non-possessive and not exclusively quantitative account of the world as it tends to happen in modernity.

The encounter with God proper to philosophical experience is mediated through being’s symbolic character. Yet, it is precisely the constitutive being-gift of every ens that awakens in the human beings the desire to see God (de Lubac 1996), readies them for the reception of an unmerited and unforeseeable divine revelation, and invites them to affirm reality in its completeness. While a metaphysics of this kind is indispensable for a sound elucidation of the philosophical meaning of experience, it still needs to deepen the role that the human spirit has in the affirmation of being’s truth and goodness. The enriching, albeit problematic, contribution of modernity to the philosophical view of experience seeks to clarify this role.

3 Threefold reconfiguration of experience

The ensuing trajectory of the understanding of experience may be described as undergoing three reversals. First, experience assumes gnoseological primacy over episteme. Then, placed in the hands of the human subject, it becomes scientific experiment and the unmediated or mediated way to obtain epistemological certainty. Lastly, recent reflections on experience open the door to both the dissolution of modern subjectivity and to the retrieval of a less unilateral account of experience. As in the past, here too experience is inseparable from the human view of oneself, God, and their relation.

3.1 A nominalist turning point

The first reversal of the meaning of experience, which took place during the fourteenth century, is elicited by a new account of the doctrine of creation and its underpinning conception of God and the metaphysical structure of finite beings. William of Ockham, arguably the clearest expositor of this reflection, claims that creation from nothing is coherently articulated when one realizes that God’s infinite and gratuitous creativity is the act of a divine absolute power (potentia dei absoluta) that puts in place radically contingent beings (more on this below).

Ockham did not see God as pure act, a self-subsisting being, but as absolute potency. Divine potency is an absolute freedom, that is, a freedom that is an unqualified and unpredetermined capacity to enact whatever God’s wisdom ordains (potentia dei ordinata). As Michael Hanby notes, with Ockham potency acquires a twofold meaning: on the one hand, it is thought as separated (‘ab-stracted’) from the realm of the existing world – a speculative manoeuvre that endows possibility with a quasi-ontological status which has priority over actuality – and, on the other hand, it is conceived without an intrinsic link with God’s nature and independently from God’s revealed nature (Hanby 2013: 108).

When he gratuitously decides to create, God’s absolute potency cannot but bring about simple individuals, ‘absolute things’, that are not formed by a real composition of esse and essence. If they were, God’s freedom would be bounded because he would no longer be able to create or reduce to nothing what he determines. For Ockham, the problem with the Thomistic ‘real distinction’ is that it makes it impossible for God to annihilate an individual without annihilating all the others that, belonging to the same species, would have the same form (1967: 51 [vol. 1]). If ‘essence’ existed it would be an absolute thing, and, hence, there would be a constitutive element of the individual, the ‘universal’ essence, already present in other individuals. For Ockham, instead, ‘every absolute thing that is distinct in place and subject from another absolute thing can by God’s power exist when that other absolute thing is destroyed’ (Quodlibet. 6.6; 1991: 506). God is free to not create an individual but, once he has created it, it cannot become (not even by divine power itself) common to other creatures, although a creature might be seen as having similarities with other individuals of the same ‘species’ (Funkenstein 1986: 124–152). For Ockham, esse and essence are different names to refer to what alone exists, i.e. the singular. Just as divine omnipotence is not pure act but the sheer capacity to act, so contingency is not just transiency and ontological dependence but absolute, simple uniqueness.

As the radical and coherent thinker he is, Ockham claims that the ‘essence’ of any finite being is formal identity with itself. Any purported similarity with other singulars, any universal, is just a mental being (ens rationis). Qualities, universals, and relations are mere concepts, different ways to refer to singulars. Inevitably, if the universals do not exist outside the mind, they coincide with the act of knowing – that is, with the abstraction that is the formation of a notion which the mind applies to other perceived singulars. Abstraction no longer is the Aristotelian-Thomistic isolation of an essence inherent in a thing. If self-identity, not form, explains the whatness of contingent beings (mental or otherwise), necessity too, as Paul Vignaux clarifies, is contingent, i.e. hypothetical: ‘si homo est, homo est homo’ (‘if a man exists, the man is man’; 1948: 25). It is ironic that a system driven by the desire to defend divine gratuity ends up proposing a metaphysics that relinquishes the perception of the world as gift and fosters a perception of freedom as the random exercise of a power detached from being’s intrinsic goodness. Although perhaps unwittingly, the bases are thus set for a moralistic reduction of religious and Christian experience.

It is key to emphasize here that, for Ockham, experiential knowledge acquires a primary role because experience is the way to know with certainty what alone exists: individual beings. Experience encompasses both external sensible objects and internal objects of the mind (knowing, willing, suffering, loving, etc.; Ordinatio 1, prol., q.1; 1967: 3–75). Both the internal and external experiences are intuitive knowledge of individual and contingent objects. For Ockham, then, knowledge takes place by means of intuitive and abstractive cognition, that is, through an experience where each object presents itself with its radical originality within the absolute novelty of its creation. Since internal experience is concomitant with consciousness of internal objects and with self-awareness, Ockham, anticipating Descartes’ cogito ergo sum (‘I think therefore I am’), contends that one is certain of oneself through understanding (‘ego intelligo’; Ordinatio 1, prol. q.1.; 1967: 40).

Before proceeding, it is worth recalling some crucial ramifications of this nominalist account of divine omnipotence and the metaphysical structure of the individual that will pave the way for both Luther’s reformation and the scientific revolution of the seventeenth century. Following the nominalist account, (1) there is no analogy between God’s being and finite beings – only univocity; (2) finite beings are not symbolic; (3) since each singular is identical to itself, each being is radically distinguished from all the others and hence the cosmos is bereft of ontological unity; (4) causality, no longer a communication of esse, becomes the production of power; (5) fourfold causality and its three axioms (agency: every agent acts insofar as it is in act; similitude: every agent acts so as to produce what is like itself; finality: every agent acts for the sake of an end), as they are understood in the Aristotelian-Thomistic tradition, become irrelevant to modern science; (6) nature and logic are homogeneous.

3.2 The modern transformation of experience

Modernity is a vastly complex and profound metamorphosis of Western thinking and living that, opposing what preceded it, took place with the scientific revolution and the philosophical and theological reflections elaborated from the sixteenth to the eighteenth centuries. During this period, the reflection on experience unfolded in three fundamental steps: first, experience became understood as experiment; second, thanks to the Enlightened account of reason, experience gained a new, markedly active meaning; third, with German idealism, it became conceived as a moment of the self-unfolding of the all-encompassing absolute.

3.2.1 Galileo and Bacon

Experience – predominantly through the works of Leonardo da Vinci, Francis Bacon, and Galileo Galilei – became the main source of scientific and philosophical knowledge. As Leonardo da Vinci famously put it: ‘wisdom is the daughter of experience’ (1925: 84). The scientific, experiential method, however, is inductive rather than deductive. Instead of using experience to validate a previously thought theory as it was done before, the scientist, by means of repeated experiences, studies the data and then discovers the reasons for what has been observed (Da Vinci 1925: 88). More incisively, Galileo claimed that experience was the only way to investigate nature over time and reach truth. Experience is not contrary to truth. For him, too, science moves from experience to demonstration, from observation to reason (2008: 85–96, 222–233, 306–315).

Although Galileo seems to have used the term experience (experientia/esperienza) and experiment indistinctly, for him ‘experiment’ gradually adopts a markedly abstract character – that is, the conditions to carry the experiment out are thought in separation from the physically existing ones (Stabile 2002: 217–241). With Bacon’s New Organon, the distinction between experience and experiment emerges clearly. Bacon favours experiment because without it (i.e. without order and a precise method) experience leads to error:

But the best demonstration by far is experience (experientia), provided it stays close to the experiment (experimento); for it is a fallacy to pass on to other things deemed similar, unless this inference is done duly and with order. (Bacon 1900: 1.70; 2005: 57–58)

Simple experience does not suffice; it is chance. What is needed is a

digested and ordered experience, not backwards and random, and from that it infers axioms, and then new experiments on the basis of axioms so formed; since even the divine word did not operate on the mass of things without order. (Bacon 1900: 1.82; 2005: 66–68)

This is key: the experiment not only corrects experience; it turns experience into itself. As Robert Spaemann wrote, ‘experiment [...] is the domestication of experience’ (2015: 217). Thus, one tends to think that to experience is to make something happen while remaining outside and in control of the situation (like with an experiment). This, of course, requires the a priori setting of the conditions to carry out an experiment, the questions to ask, and the drive always to be in control of the situation. In this way the experiment/experience can be repeated as needed and conclusions strengthened.

Although discoveries do take place, novelty – understood as the substantial change that echoes the radical novelty proper to creatio ex nihilo as understood, for example, in the Thomistic tradition presented earlier (section 2.2) – has faded from view. It is not a coincidence that Bacon, still reluctant to dismiss the centrality of God altogether, claimed that creation from nothing is a sound religious belief and that the traces of God in the world (the symbolic character mentioned above) are too faint to argue for God’s existence. Naturally, this perception of the world entails the dismissal of the causal axiom of similitude and, consequently, it fosters the elucidation of the world without God. This experience of the world no longer leads to God (regardless of whether he is thought to be pure act or absolute potency). The world becomes an ‘object’ (that which is thrown in front of a subject) and the subject, through knowledge, can gain power over it (Bacon 1900: 1.3, 1.116, 2.4; 2005: 33, 90, 103). The subject is called to master nature in ever more efficacious ways, so that, as Bacon hoped, one could heal the effects of the original fall (1900: 2.72; 2005: 221).

3.2.2 Locke and Descartes

The influence of Ockham’s nominalist philosophy can be perceived also in the one common root shared by John Locke’s empiricism and René Descartes’ rationalism: the significance of intuition – the sensible or intellectual immediate perception granted through experience – for certain knowledge. For Locke, experience, which regards both the sensible objects and the internal operations of the mind, is the source of all of our ideas (An Essay Concerning Human Understanding 2.1–4; 2006: 95–97). Besides sensation, experience also includes ‘the perception of the operations of our own minds within us [...] perception, thinking, doubting, believing, reasoning, knowing, willing, and all the different actings of our own minds’ (Essay 2.1.4; 2006: 96–97). Certainly, they cannot be identified, and they remain intuitions of two different objects. Yet, both experience (of the internal operations and of the external objects) and conscience are intuitive, immediate knowledge.

Cartesian self-reflection also has the form of intuition. Descartes’ seeking indubitable knowledge rejects as uncertain what comes from sense knowledge and other external sources (authority, history), and recognizes as certain what comes from self-reflection. For Descartes, ‘there are no paths to certain knowledge of the truth accessible to men save manifest intuition and necessary deduction’ (Rules 12.425; Descartes 2009: 48). Thus, Descartes claims that just as we become aware of external objects through perception, through inward perception we become aware of our own thinking and hence of our own being. If sense perception is the prime analogue for experience, and consciousness is a faculty for internal perception, then experience remains the mode of knowledge par excellence – although, admittedly, Descartes himself was not very fond of the term ‘experience’ (Armogathe 2002: 259–271). More importantly, whatever is sensed is regarded as an object placed before reason. As objects, beings are reduced to brute facts, to res extensa (Latin for ‘extended thing’ or material substance) deprived of ontological interiority. The pursuit of unmediated (evident) knowledge, resting in the rejection of the world’s creatureliness, leads to a radical dualism between reason and its object that still haunts much of the current subjectivistic understanding of experience.

3.2.3 Kant and Hegel

Immanuel Kant’s philosophical reflection also takes place within the modern turn from experience to experiment. Yet, more radically than his predecessors and following the mathematical and physical scientific models, Kant argues for the understanding’s a priori control of the content of human experience (Critique of Pure Reason [CPR] B XIII; Kant 2003: 50–51). Kantian transcendental knowledge deals with our way of knowing rather than with the object itself (CPR B 25; 2003: 58–59) because it is only thus that we can obtain valid knowledge, that is, knowledge that brings together sense perception and understanding (CPR B 134–135; 2003: 154–155). Kant thus seeks to correct the limits of empiricism and rationalism by bringing them together in a higher synthesis. Whereas rationalism underestimates recourse to sense experience and trusts the pure deductions of one’s understanding, empiricism mistrusts the a priori activity of the mind and relies on what experience can offer. Uniting them, Kant, on the one hand, overcomes empiricism by establishing the possibility of a priori judgements that are universal and necessary. On the other hand, he limits rationalistic claims by affirming that the understanding’s synthetic activity is empty without the empirical givens of the experience. Similarly to divine creative thought, our intelligence builds for itself its own object and knows sensible objects (phenomena without interiority) that are ordered by reason’s a priori synthetic activity.

Along with these two ways of knowing, Kant’s transcendental dialectic recognizes a third one, pure reason, which is the understanding that does not refer to a possible experience and that seeks to know the suprasensible objects. Kant’s pure reason, like a dove (CPR B 8–9; 2003: 46–47), strives to know what matters the most: God, immortality (the soul), and freedom (the world as undetermined). Although pure reason can think these three ideas, it cannot know them. They escape the parameters of valid knowledge. Their key role, then, is to function as regulatory, ordering principles of human knowledge. In order to ensure the unity of sciences, but without any objective knowledge, pure reason represents the world as if it derived from a creating God (CPR B 693–698; 2003: 546–549). Thus, the idea of God, for Kant, speaks more of us than of God in himself (Prolegomena, section 58; Kant 1995: 129–133). One needs to be modest and not claim that the mysteries of God and human freedom can be known; that is, we cannot relate to God, freedom, and the soul as if they were objects within the reach of our dominion and that could be built a priori. We cannot know either what things are in themselves or the divine absolute.

Despite his speculative modesty, Kant insists that God may be reached by practical reason. This practical approach, however, while avoiding the cosmological reduction of the proof of God’s existence, falls into the hands of an anthropological reduction: Christ is the representation of the ideal of ethical perfection (Religion 6:66; Kant 1998: 83–84) and Christ’s utter obedience is submission to the pure laws of reason (Religion 6:62; 1998: 80–81). Similarly to Baruch Spinoza’s Ethics (1677; see Spinoza 1992), Kantian morality seeks to replace Christian experience.

Although Hegel considered Kant’s system invaluable in many respects, one of the points where he considers it falls short is that Kant circumscribed the categories of understanding to the subjective level, as if they only regarded the pure concepts of human understanding. Kant, for Hegel, did not see that the transcendental self is, in reality, the absolute concept (Begriff). For Kant, the transcendental subject was not the ‘I think’ of a given psychological conscience, but the self’s first act, thought’s originary unifying power that is not an object of conscious experience. Hegel claims that this account does not realize that the knowledge of the finite world always entails that of the absolute, and therefore the categories of thought necessarily lead to the absolute spirit because they are moments of its immanent self-development. It is the absolute and living thought – and not just simply Kant’s transcendental self – that differentiates itself and creates its own object. Logic and human knowing are part of the absolute concept’s self-development. Away from this ontological framework, Hegel thinks that it is impossible to overcome the dialectic opposition between subject and object and reach the syllogistic truth that accounts for the truth of absolute Idea. For Hegel, then, the subject is the absolute living spirit and truth the identity of identity and non-identity. As André Léonard indicated, Hegel’s idealist philosophy overcomes both Kant’s dualistic separation through the principle of identity (being is total self-revelation and interiority of being and objectivity) and the principle of consciousness’ immediacy to itself by means of the spirit’s absolute and immanent self-mediation (Léonard 2006).

The Phenomenology of Spirit (whose intended title was ‘the science of the experience of consciousness’, 1977: 56 [section 88]), as well as the more encompassing Science of Logic (2010), constitute a remarkable effort to follow the excruciating path of the absolute concept’s immanent self-differentiation and preservation of the differences in a greater unity – one that regards both God in himself before the creation of the world and the whole history of the world (Hegel 1998). In fact, in Hegel we see the first attempt to conceptualize the structure of historical experience which, however, does not offer a successful integration of the subject’s transcendence and its historical determination, since it tends to interpret history as the expression of the concept’s absolute subjectivity (1995: 1–116).

The experience of consciousness is that of becoming aware that at stake in knowing is the absolute, eternal, and circular process of the absolute concept: from God to nature, from nature to finite spirit, and from finite spirit to absolute Spirit (Hegel 2015). Thus, one cannot conceive of the experience of consciousness as happening away from the absolute, or as if it had the absolute as yet another object. Hegel’s system – which he claims to be a philosophical re-elaboration of the Aristotelian unmoved mover, enriched by the modern account of spirit that brings the role of consciousness to bear in being – takes its architectonic principle of absolute negativity, which quickens the life of the spirit and prevents the absolute spirit from being another iteration of Spinoza’s lifeless substance, from his perception of the Lutheran understanding of Christ’s kenosis.

Christ’s death [...] ‘God himself is dead’ says a Lutheran hymn, expressing an awareness that the human, the finite, the fragile, the negative, are themselves a moment of the divine and that they are within God himself; that finitude, negativity, and otherness are not outside of God and do not, as otherness, hinder unity with God. Otherness, the negative, is known to be a moment of the divine nature itself. (Hegel 1998: 326, original emphasis)

Absolute Spirit’s syllogistic process of negation, negation of the negation, and affirmation is Hegel’s metaphysical account of the Absolute’s process of self-determination of which the human being is a part. Rather than a moralistic account of human experience like in Kant, Hegel’s proposal is endowed with a profound gnostic strain (Schmitz 1977).

For our reflection on the philosophical meaning of experience, it is fruitful to recognize that Hegel’s account of absolute spirit brings back the mystery of God, understood as absolute subject, to the heart of human experience, and calls for a greater realization of the role of freedom and of a non-dualistic rendition of the relationship between unity and difference (Fabro 2013; Chapelle 1964; Lakebrink 1968). Further, as Claude Bruaire (1983) proposes, the centrality of the negative may be seen as the reverse of the gift-character of being (see section 2.2; also Christian Experience: A Catholic View) which thereby becomes the internal possibility of overcoming negativity. Finally, while the role of the active intellect in the great scholastic synthesis of Aquinas, Bonaventure, and Scotus prevents us from categorizing their account of the experience of the world as giving undue weight to finite beings and lessening the role of the human subject, Hegel’s system (and in a different way, those of Fichte and Schelling) represents a formidable attempt to account for a more profound view of the spirit in the constitution of the world.

Along with these more positive openings, there are three problematic questions that open the door for the third reversal of the concept of experience. If the first issue regards the questionable capacity of the Hegelian system to uphold finitude’s integrity without surrendering to its pantheistic proclivities that have arguably occasioned the rise of modern atheism, then the second issue, prompted by his innovative defence of the role of history in the experience of the world, is the need to articulate how history determines experience. The third formidable question that Hegel’s system leaves open concerns the identity of the one who speaks in the Science of Logic (the Triune God? Hegel? Language? Any human being? All of these?). These thoughts, along with the implications of the absolutization of subjectivity, pave the way for an account of experience as the living out of human historical finitude freed from the interpretative dominion of subjectivity. Before presenting this, we need to examine two influential contributions that, in different ways, made possible the third reversal.

3.2.4 Schleiermacher

The work of Friedrich Schleiermacher, ‘arguably the most important Protestant theologian since Calvin’ (Jay 2005: 88), accepts the challenges that Lessing’s claim to separate contingent historical truths from the necessary truths of reason (2005: 85) and Kant’s philosophy brought to Christianity. Schleiermacher responded by offering an account of religious experience (1994; 1996) that determined the theological debate of the nineteenth and twentieth centuries (Proudfoot 1985; Zahl 2017: 180–183; 2020: 23–29). Of his reflection, it suffices here to recall what was to him Christianity’s true foundation: ‘the feeling of absolute dependence’ (Schleiermacher 1994: 12). This unique insight not only represents a cogent response to Kant’s proposal, as an alternative to Hegel’s, but it also speaks of a specific way to account for the kernel of the philosophical view of experience – that is, the speculative knowledge and awareness born in time from the encounter of all the person with others, the world, and God.

A few biographical notes are indispensable for understanding Schleiermacher’s proposal. He belonged to the Reformed tradition and was raised in a Pietist community (Gerrish 2001) that emphasized, among other things, the importance of biblical preaching, spiritual rebirth and repentance, devotional and charitable exercises, and active missionary thrust through personal conversion testimonies. Albeit immensely varied, Pietism perceived religion as inward, highly personal, and marked by a heightened emphasis on the experiential relation with Jesus Christ. Particularly significant for Schleiermacher was the emotional intensity of religious experience. ‘Christian doctrines’, he wrote in The Christian Faith, ‘are accounts of the Christian religious affections set forth in speech’ (1994: 76). Without Pietism’s ascendency, it is difficult to make sense of Schleiermacher’s experiential emphasis. Additionally, besides studying Kant’s work, he frequented the Romantic circles that reacted against Enlightened rationalistic philosophies, and stressed individuality (against the abstractions ‘man’ and ‘human nature’), feelings, and the (aesthetic) unrest of Sturm und Drang (German, literally ‘storm and stress’; a literary movement arising in late eighteenth-century Germany).

The meaning of ‘feeling of absolute dependence’ is better seen when we recall that Schleiermacher places religion within the sphere of human consciousness. Yet, rather than thinking of religious consciousness in terms of morality (as if religion were simply a human action) or doctrine (as if it were a body of beliefs that could be accessible to reason), Schleiermacher conceives it as the self-mediation that undergirds the conscious and practical operations of the human spirit and which neither reason nor will can successfully portray. Thus, in contrast to Kant, religious consciousness regards the undifferentiated unity of subject and object which, to avoid confusing it with doctrine or ethics, is described as a ‘feeling of totality’ (1996). Religion is immediate consciousness of totality – where totality is not an object for religious awareness. As pre-thematic and pre-moral, this feeling can be grasped only indirectly before it breaks up in the inevitable opposition in which either the subject or the object dominates.

Although the felt totality is undifferentiated, it still manifests a more subjective element (feeling) and a more objective element (intuition). According to the former, the immediacy of consciousness is the ‘feeling of freedom’, and according to the latter it is the ‘feeling of dependence’. Thus, religious experience for Schleiermacher lies in the feeling and intuition of the individual’s relationship with the whole (1996: 4–19). In its originary dimension, self-consciousness entails the reference to the ground of the totality as other from the individual’s self-consciousness. For him, this feeling is best described as a ‘feeling of absolute dependence’ (schlechthin abhängig) (1994; 1996: 12). It is a permanent, dynamic, and pre-thematic awareness of a determining Other without which our self is not recognizable (Zahl 2017: 181). The ‘feeling of absolute dependence’ implies, therefore, the ‘[w]hence of our receptive and active existence’ (Schleiermacher 1994: 16) that is normally called God. The divine whence is not conditioned by any previous knowledge about God one may have. Rather, it is the other way around. The concept of God evolves from this feeling – a claim that implies that the ‘God-consciousness’ is included in the immediate ‘self-consciousness’ (1994: 16–17). Appearance to the contrary notwithstanding, the ‘feeling of absolute dependence’ upholds a lively felt perception of Christianity because it ‘manifests itself in a particular range of concrete emotional states’ (Zahl 2017: 182). It is at the root of other feelings (such as the love of God, fear of death, joy over divine forgiveness), dogmatics when objectified in knowledge, and ethics when instantiated in doing (1994: 111).

Among others, Karl Barth (1982) criticized Schleiermacher’s understanding of Christian experience and the importance ascribed to it. For Barth, Schleiermacher’s use of experience overemphasizes the anthropomorphic and subjectivistic dimensions of Christianity and divine revelation. Schleiermacher’s concept of experience seems to derive its meaning from the common aesthetic experience. For Barth, Schleiermacher neglected that ‘God can only be thought of as a subject and not the predicate’ (1982: 253). God and his historical revelation are subordinate to human subjectivity. As Martin Jay notes, for Barth, ‘in his reliance on experience’ Schleiermacher ‘made a mockery of God’s promise of eternal life, which, after all, could not be derived from anything already undergone by even the most pious believer’ (Jay 2005: 101–102). According to this critique, the object of true devotion seems to have become a function of the individual’s experience of the absolute.

It is important to mention here that Wilhelm Dilthey follows the hermeneutical path opened by Schleiermacher with its emphasis on life (Leben) and the historicity of human subjectivity. Dilthey argues that the scientific character of historical knowledge rests on the fact that lived experience (Erlebnis) offers the immediate certainty needed to interpret historical events rightly. Whereas Erfahrung (experience) remains at the level of the intellect, Erlebnis gives the pre-comprehension of the sense of the historical totality – which is neither reducible to Hegel’s absolute spirit nor to Schleiermacher’s self-consciousness but to the vital substratum that remains unchanged. Erlebnis ‘is a distinctive mode in which reality is there-for-me [...] because I have a reflective awareness of it, because I possess it immediately as belonging to me in some sense’ (1985: 223). Nevertheless, in Dilthey this ‘substratum’, perhaps due to the obscurity of his metaphysics of life, seems to be absorbed by the relativistic character of historical consciousness (1960: 194; see Jay 2005: 222–234). Some of Dilthey’s notable ideas influenced authors such as Heidegger and Gadamer, who pursued in different ways the open task of thinking the meaning of finite historical singularity.

3.2.5 Kierkegaard

Søren Kierkegaard’s profound, fascinating, and complex writings offer (among many other contributions) a Christian existentialist approach to truth whose critique of the Hegelian idealist system and established Danish and Protestant Christianity represents a remarkable attempt to ponder anew the significance of the singularity of the individual persons together with their radical difference from and relationship with God. In this sense, Kierkegaard’s work provides a cogent alternative, on the one hand, to the idealist absorption of experience’s access to truth into the realm of the spirit’s subjectivity and, on the other hand, to Schleiermacher’s functionalization of God to pious self-consciousness.

Kierkegaard was greatly indebted to Hegel. From him Kierkegaard learnt, among other things, the significance of the spirit (Geist) and its self-realization through a process (1980: 13) as well as that of dialectics (‘I am not a poet, I go at things only dialectically’, 1983: 90). In light of the foregoing theological reading of Hegel, it also could be argued that the centrality of thinking the nature of Christianity (Hegel 1998: 53) and its God is also a common endeavour. Kierkegaard, however, also was the greatest opponent to Hegel and Danish Hegelians (Stewart 2003). Hegel, claimed Kierkegaard, denatured Christianity and rendered it abstract. He produced ‘a system embracing the whole of existence, world history [...] [but] he himself does not personally live in this huge, doomed place’ (Kierkegaard 1980: 43). The system is a ‘pure ideality’ where ‘everything takes place of necessity’ and with which ‘the individual person is not involved’ (1980: 93). A system of existence is impossible for anyone but God (1992: 118–125). Whereas Socrates saw well that ‘the knower is an existing person and that to exist is the essential’ (1992: 207), modern philosophy missed the singular altogether: ‘in a highbrow way through speculation’ this philosophical system ‘pantheistically abolish[ed]’ the qualitative difference between God and the human being (1980: 117) – the irony being that modern philosophy tries to pass itself for Christianity when it is only paganism. Instead, for Kierkegaard, Christianity upholds that ‘the single individual is higher than the universal’ and that its greatness is ‘to determine his relation to the universal through his relation to the absolute’ (1983: 70). This ‘human being’, the single individual, is a ‘synthesis of the infinite and the finite, of the temporal and the eternal, of freedom and necessity’ (1980: 13). The task to carry out this synthesis is a paradoxical and ceaseless project that unfolds as the singular accepts and lives out its ineliminable responsibility before God and, above all, before Christ. In fact, for Kierkegaard, paradox is the relationship between a singular, knowing individual and the eternal truth.

To present this view of the finite human spirit Kierkegaard uses an ‘indirect method’ of communication, since the direct one – focused on the conceptual account of what is – loses sight of inwardness, that is, of concrete human existence (1992: 249). The works he authored under a pseudonym or those that have him as editor argue for the issue at hand through indirect communication, whereas those in which he is the named author follow the direct method. This approach has three advantages. First, imitating God’s method through which he is present in creation but ‘not directly’, this method helps the single individual to take a position (1992: 242–243). Second, it allows Kierkegaard to illustrate different possibilities of human existence without identifying himself with all the views presented by the ‘author’. He thus argues that human existence unfolds its possibilities in either an aesthetic, philosophical, or religious sphere – the last one being the highest, contrary to the immanent and necessary movement of the Spirit in Hegel for whom philosophy is the summit (Hegel 2015: 302–315). Finally, besides illustrating the three interrelated stages of the determination of the human spirit, the use of pseudonyms helps him to argue for the reality of faith’s radical subjectivity as the graced apex of human existence into which the individual is called to leap, leaving behind not rationality but speculative securities.

To clarify the role of the singular subject, it is key to realize that when Kierkegaard famously speaks of truth as ‘subjective’ (1992: 15–17, 189–251), he is not rejecting truth’s objectivity or fostering a relativistic or subjectivistic account. Rather, ‘objectively the emphasis is on what is said; subjectively the emphasis is on how it is said’ (1992: 202, original emphasis). The former regards the categories of thought and upholds the ontological dimension of the truth of God, the world, and the individual. Building on this one, subjective truth regards the individual’s inwardness, that is, the finite’s spirit relationship with truth. To claim, therefore, that subjectivity is truth is to defend human freedom as it is called to engage the eternal. Thus, this paradoxical claim is not so much a gnoseological description of truth but an ethical one. ‘Only in subjectivity is there decision, whereas wanting to become objective is untruth’ (1992: 203). Speculative thought cannot comprehend that ‘subjectivity is truth’ (1992: 217) and hence it claims that it is, conceptually speaking, ‘untruth’ (1992: 207). Thus, to contend that ‘subjectivity is truth’ is to view subjectivity, human existence, as the highest engagement of freedom with the eternal. In this sense, the radical paradox – that overcomes Hegel’s panlogism – is not so much the finite spirit, but the incarnate logos. ‘The eternal truth has come into existence in time. That is the paradox’ before which every human spirit is to take a stand (1992: 209).

These brief remarks on Kierkegaard’s existentialist proposal helps us to see that he frees the reflection on the singular person’s encounter with God and others – and hence on what here is understood as philosophical experience – from the domination of idealist subjectivity. He does so while appropriating some of modernity’s key insights. It is thus not surprising that he exercised such a great influence on many of the authors that form the hermeneutical turn.

3.3 The hermeneutical turn

If Ockham’s nominalist philosophy gives pride of place to experience and intuition, and the various modern reflections put experience at the service of scientific experimentation (Galileo, Bacon) which eventually finds its ultimate justification in the subject (Descartes, Kant, and Hegel, among others), Martin Heidegger’s work represents the key turning point in the relinquishing of the centrality of the subject. He also gives rise to various ‘postmodern’ phenomenological endeavours (Merleau-Ponty 1964; Gadamer 1998; Ricoeur 1992; Levinas 1996; Marion 1998) as well as deconstructionist reflections (Derrida 1997; Foucault 1970).

The foregoing reflection on experience showed that modern transcendental philosophy understood the subject as an activity that posits and transforms finite beings into objects that become intelligible only when they conform to the subject’s epistemological structures. Subjectivity is self-evident and knows itself in the reflection of its own acts (Ockham, Descartes, and Edmund Husserl, among others). Thus, the subject can serve as the ground and guarantor of truth and of what is experienced. Granting experience priority over episteme ended up giving epistemological and ontological primacy to the subject. In their own specific ways, Descartes’ res cogitans (Latin, literally ‘thinking thing’), Kant’s transcendental self, Hegel’s absolute Spirit, Nietzsche’s will to power (1967), and Husserl’s transcendental consciousness (1973; 1983) have subjectivity as the ultimate, unsurpassable foundation.

As Ramón Rodríguez has clearly shown, pondering the question regarding the meaning of being in its relation with Dasein (that is, ‘openness’ and not as common translations have it: ‘being-there’ or ‘human existence’), Heidegger’s Being and Time (2010), although not fully successfully, represents the initial moving out from transcendental subjectivity and of thinking of being away from the dualistic opposition of subject and object (Rodríguez 2006). Some of the key elements that signal this shift from modern subjectivity are that, for Heidegger, existence’s radical finitude manifests Dasein’s impossibility to be the foundation of itself and the world; existence is not thought as subjectivity; and the account of understanding as project is not the presentation of the activity of the subject that posits its objects but the opening of a field thanks to which things can reveal themselves. Existence’s openness (Erschlosenheit) suggests the overcoming of the subject-object dualism and the all-encompassing horizon of subjectivity. On the other hand, since openness is thought to be the key element of Dasein’s constitution, it is difficult to avoid thinking that Dasein posits and gives meaning to being. It is with The Essence of Truth (1998) that Heidegger’s subjectivistic ambiguities lingering in Being and Time are dissolved. As this and successive works show, to think of being means finding ways to express the space of illumination (Lichtung) from itself (in its veiling and unveiling), and not simply as the revelational dimension of beings. This, along with the category of event (Ereignis) and of history, leads Heidegger away from any form of objectivism and the domination of subjectivity. The repetition of the history of being, for him, will be both the overcoming of metaphysics (being’s long path from the Greeks to Nietzsche) and the true experience of being. Yet this experience of being is not a retrieval of Aristotelian-Thomistic metaphysics.

According to Heidegger, philosophy’s fundamental question can be asked adequately only by way of a leap out of metaphysics because the proper object of thought is not ‘being’, in either its ontological or phenomenological meaning, but what enables manifestation or presence to be given at all (Sheehan 2001; 2021). ‘What is’, for Heidegger, is Ereignis (event), the movement of opening itself up and belonging, a reciprocal expropriation of appearing and Da-sein. Givenness needs that to which it gives, and the latter belongs to the former which withdraws in its giving (Heidegger 2003: 251–252). This is vital for an adequate grasp of the significance of Heidegger’s contribution to a reflection on experience: the giving and reception proper to the ‘event’ is not due to a cause behind Ereignis, but to human finitude itself. If Da-sein’s finitude accounts for Ereignis, not as the extrinsic cause but as being within Ereignis itself, then finitude is not a dialogical partner of the infinite. For Heidegger, finitude does not need an absolute to render its existence intelligible. Finitude can be accounted for from itself. As Hans Jonas argued, Heidegger (2002: 69), philosophizing independently from the Catholic and Christian God, considers that ‘revelation is immanent in the world, nay it belongs to nature; i.e., the world is divine’ (Jonas 2001: 48). Quite consistently do the gods appear again in Heidegger’s philosophy. ‘But where the gods are, God cannot be’ (Jonas 2001: 248). In contrast to what has been argued thus far, one may rightly wonder whether, where God has been evacuated from human existence, a human experience of oneself and the world can take place, or whether the human being, under the guise of finitude, does not remain the ultimate measure of what is.

Derrida’s deconstruction of what he calls modernity’s logocentrism presents a complete erasure of the subject; it proposes replacing all-encompassing narratives and unifying horizons of meaning with the ongoing play of differences that neither presuppose nor lead to the presence of a unifying whole (1997; Gasché 1986). Differently from this postmodern approach, Hans-Georg Gadamer’s masterful account of experience (Erfahrung) in Truth and Method (1998: 346–362) carries forward Heidegger’s dismantling of the subject through a phenomenological hermeneutics. For Gadamer, hermeneutics is not just a collection of methods through which a detached viewer examines a given text or period and tries to make sense of it. Rather, it is a philosophy (which, of course, includes method) that seeks to give an account of key human questions while being mindful that ‘the being of the interpreter belongs intrinsically to the being of what is to be interpreted’ (Gadamer 2007: 263).

Gadamer, in line with Heidegger, criticizes the modern perception of experience as pure immediacy patterned after the mode of perception. He claims that ‘experience teaches us to acknowledge the real [...] to know what is [...] Real experience is that whereby man becomes aware of his finiteness’ (1998: 357). Three interdependent elements of this experience of finitude are essential for our reflection: tradition (and history), language, and human community. Modernity’s claim to elaborate a presuppositionless reflection from which all the categories of thought may be derived forgets that thought happens in language – which precedes and cannot be reduced to thought. Gadamer notes that for Hegel language reaches its perfection in the logic that, as we saw in the previous section (3.2.3), thinks of all the language categories as immanent and necessarily related moments of the unfolding of the concept. While in a certain sense this is the case, Gadamer claims that Hegel does not see that language ‘also returns from [the objectivity of thought] in the reabsorption of all objectification into the sustaining power and shelter of the word’ (1976: 94).

Thinking abides in language. From this point of view, a distinction needs to be drawn between language and the unfolding of the content of the absolute spirit as it happens in Hegel’s Logic. Tradition, rather than simply a set of texts, rites, customs, etc. is language: ‘it expresses itself like a Thou’ (Gadamer 1998: 358). In this way, experience is open to that (and those) that preceded it and leads to future experiences. Here again, tradition is not detached from its speaker and in need of being brought to life at different moments of ‘history’. Rather, tradition as language calls for the historical dimension of experience whereby one is aware of the otherness of the other in all its temporality and the meaning for oneself. Just as a non-unilateral account of language requires seeing its return from language to being and history, so the historical consciousness shows that one is always part of the ever-open event of language. Lastly, the hermeneutical experience of the other (hence of tradition and language) is real because it leads to the openness to the other – which includes both the obedient hearing and the acceptance of what contradicts or corrects. As Aeschylus said, the suffering involved in learning teaches us the depths of our own finitude. Hermeneutical experience contests the disengaged observer that claims to be the ground for epistemic truth and ‘brings to our reflective awareness the communality that binds everyone together’ (Gadamer 2007: 263). Hermeneutical consciousness culminates for Gadamer in ‘readiness for experience’ (1998: 325), that is, the openness to discover what is real that shuns an ahistorical dogma. Hermeneutics has the great value of giving priority to the questioning and the linguistic, communal, and historical context with which one is always already involved. At the same time, just as the existence of the questioner who posits questions signals a difference from language that immanent finitude cannot account for, so concrete finitude escapes the universal character of language.

4 A pragmatist proposal: James

Different from Kierkegaard’s Christian existentialism but with various affinities to Dilthey’s Erlebnis, Schleiermacher’s ‘feeling of absolute dependence’, and Heidegger’s Es gibt (it gives), the influential work of William James proposes, first, the concept ‘religious experience’ to give an account of the kind of relationship the individual keeps with the divine, and, later on, an unfinished metaphysics of ‘pure experience’. It suffices here to recall some of the key features that experience has for him.

Published in 1902 under the title The Varieties of Religious Experience, this masterpiece of religious psychology offers, as the subtitle suggests, a study of human nature in its relation to a generically conceived divine that seeks to be as encompassing as possible. Continuing the path opened by Schleiermacher, James conceives of religious experience as prior to any specific moral or dogmatic expression and thus capacious enough to be at the basis of any religion and scientific epistemology. For him religion consists, first, in an ‘uneasiness’, ‘a sense that there is something wrong about us as we naturally stand’ and, second, in its solution, which is ‘a sense that we are saved from the wrongness by making proper connection with the higher powers’ (1987: 454). At the beginning of his lectures, James offers a working definition of religion that becomes the single mould into which any human religious expressivity can fit. Religion, he writes, is ‘the feelings, acts, and experiences of individual men in their solitude, so far as they apprehend themselves to stand in relation to whatever they may consider the divine’ (1987: 36). Clearly, the universal applicability of this definition requires, on the one hand, a pluralistic view of religion:

The divine can mean no single quality, it must mean a group of qualities [...] We must frankly recognize the fact that we live in partial systems, and that parts are not interchangeable in the spiritual life [...] If we are sick souls, we require a religion of deliverance; but why think so much of deliverance, if we are healthy-minded? (James 1987: 436–437)

On the other hand, it also rests on a deity that, rather than a transcendent being, functions as the response to the human religious need. If for Schleiermacher the divine is ultimately integral to our feeling of absolute dependence, for James’ pragmatism, ‘God is real since he produces real effects […] on the personal centres of energy of the various subjects’ (1987: 461). James follows a modified version of C. S. Peirce’s pragmatism and claims that

to develop a thought’s meaning we need therefore only determine what conduct it is fitted to produce; that conduct is for us its sole significance; and the tangible fact at the root of all our thought-distinctions is that there is no one of them so fine as to consist in anything but a possible difference of practice. (James 1987: 399)

A religious expression is true, then, if it works, if it makes a difference in human life.

When considering the singular religious individual, James has in mind mostly the ‘effective geniuses’, that is, those persons in whom ‘a superior intellect and a psychopathic temperament coalesce’ (1987: 29). The ‘psychopathic temperament’ gives us

the emotionality which is the sine qua non of moral perception; [...] the intensity and tendency to emphasis which are the essence of practical moral vigour; and [...] the love of metaphysics and mysticism which carry one’s interests beyond the surface of the sensible world. (James 1987: 30)

The identification of the ‘genius’ with the psychopath not only speaks of the decisive role that, for James, psychology has in religion (1987: 433), but it also signals our civilization’s technological paradigm (Grant 1991; Del Noce 2017: 68–85). In fact, if experience as experiment (as making) is the genuine form of thinking, it is the exception – that which was thought impossible but actually was brought to be or happened – that becomes the norm of truth, not what something is by nature. In James’ thought, the pathological becomes the yardstick of normalcy. Just as the psychopathic genius is the archetype of the religious individual, so the mystical states of consciousness are ‘the root and centre’ of personal religious experience (1987: 342). Rather than being the exception that confirms the norm of human experience in its mediated relation to the divine, for James, the ineffable, noetic, transient, and passive state of the human soul which he calls mystical experience (1987: 343) gives rise and meaning to human religiosity.

Between 1904 and 1905, James wrote a series of essays (1987: 1141–1182, 1186–1192, 1203–1214), where he sought to articulate what he called the individual’s ‘pure experience’ or ‘the immediate flux of life which furnishes the material to our later reflection with its conceptual categories [...] a that which is not yet any definite what, tho’ ready to be all sorts of whats [...]’ (1987: 782–783, original emphasis). For this metaphysics, the ‘whats’ do not regard the ontological difference that characterizes the Aristotelian-Thomistic metaphysics, but rather relations between experiences of one or several individuals. Some of these relationships constitute objects, other persons, and others both (1987: 1159–1182). Although James never finished clarifying his meaning, it is possible to say that to see pure experience as pre-reflective immersion in the flux of life resonates with Dilethey’s Erlebnis. When it is considered an undetermined ‘that’, ‘pure experience’ is what precedes the division between subject and object, facts and meaning. In this sense, it regards, to use Heidegger’s later term, ‘that what gives’ (Es gibt). Language is never capable of expressing fully this ‘pure experience’ that remains larger than language and, as such, ‘pure experience’, similarly to Schleiermacher’s feeling of absolute dependence, is an immediate contact with the totality.

According to the American pragmatist philosopher John E. Smith, also editor of Jonathan Edwards’ masterpiece Religious Affections, James’ understanding of experience meets three obstacles that he seems unable to overcome. First, to consider that the original data for religion are different states of the total self

gives credence to the supposition tha[t] an experiential approach means no more than an attempt to reduce God to a tissue of human experience and to constitute religion in a way that makes it unnecessary to appeal to a disclosure from beyond man’s consciousness. (Smith 1968: 47)

Second, the attempt to establish a parallelism between religion and scientific inquiry seems to deduce the existence of the divine from human consciousness. Third, it upholds an inadequate empirical conception of experience as the immediacy of certain data to the mind of the individual.

Smith’s own, yet still not well-known, contribution offers a more balanced account of God’s transcendence and the singular’s experience of him. For Smith,

experience is the many-sided product of complex encounters between what there is and a being capable of undergoing, enduring, taking note of, responding to, and expressing it. As a product, experience is a result of an ongoing process that takes time and has a temporal structure. (Smith 1968: 23)

In contrast to the common empiricist account of experience, Smith argues that experience is the result of ‘a multidimensional encounter between a concrete person and whatever is to be encountered’; it embraces the ‘moral aesthetic, scientific, and religious dimensions’ which ‘give purpose to the life of an individual person’ and grants ‘objective disclosure of what is there to be encountered’ (1973: 11). Smith’s proposal recuperates within the pragmatist tradition a concept of experience that is more faithful to the constitutive elements of experience, that is, the practical or speculative knowledge that emerges in time as the fruit of the eventful engagement of all of ourselves with others, the world, and, ultimately, God.

5 Conclusion

The etymology of the concept of experience invites us to understand its verbal use (to experience) as a trying and a risking to go through to the end of something or of a situation. Its noun use (an experience) can be seen as a practical or speculative knowledge attained in time or as the person’s lived awareness of meaning. Both the action and the knowledge presuppose the person who acts, the content of what is learnt, the life that is lived, the language in which both the person and the content are expressed, the time they indwell, the divine principle that unites and orders all that is while keeping distinctions and indicating a direction, and the actual encounter of all these. The unique difficulty entailed in the philosophical elucidation of experience derives precisely from its very wealth: experience brings together all these elements to human awareness. Further, having been enriched and awakened, this awareness occasions the movement of the human spirit both towards a more profound perception of what one is and what it means to live, and towards God, who remains semper maior (ever greater), through the preceding reality whose intrinsic meaning asks the human person to bring it to light by organically transfiguring it.

The Christian doctrine of creation deepened the perception of the symbolic character of finite beings first developed in Greek thought, and secured the unity and distinction between a radically transcendent God and the world. This view, examined here through the Thomistic synthesis, deepened and corrected the Greek perception of experience as the knowledge that emerges as the fruit of the eventful and laborious engagement with the world, others, and God. Modernity’s threefold reversal of the concept of experience – experience as the form of knowledge; experience as experiment carried out by the human subject who has in itself the measure of truth; experience of historical finitude that seeks to free itself from the interpretative dominion of subjectivity – brought the awareness of the role played by the human spirit and time in the ontological constitution of beings.

The preceding philosophical reflection on experience also came to terms with the historical limits of the speculative development of the various accounts of experience. Whereas Greek and Latin philosophical thought on experience until the thirteenth century remains incomplete, in that they need to come to terms more directly with the role of the human spirit in its experience of being and the world, the various rejections of God and of the symbolic character of reality in modernity and postmodernity fostered a dualistic view of reality in which the world and the human subject coexist in a univocal, dialectic, or equivocal relationship. Nominalism gave way to the primacy of self-identity as self-reference and reestablished unity as a whole in which relations between individual units remain extrinsic and dialectic (subject and object, history and episteme remained insurmountably opposed). The Hegelian syllogistic attempt to overcome Kantian dialectics yielded an unprecedented absolutization of the spirit and a panentheistic account of the relationship between the absolute and the finite (universality and singularity, reason and experience subsist in an irreconcilable tension). The rejection of subjectivity’s self-reference brought to the Heideggerian and, to a certain extent, the hermeneutic historization of finitude. It also occasioned the postmodern enshrining of equivocal relationships among ‘units’ that do not belong to a greater whole. Kierkegaard’s retrieval of the singularity of the finite spirit in its paradoxical relationship with the incarnate God represents, on the one hand, an opportunity to reconsider more radically the role of freedom in human experience, and, on the other hand, a challenge to the anthropomorphic reductions of religious experience of Schleiermacher and James.

Considering the positive and negative outcomes of the speculative development of experience suggests that we should reject the always alluring temptation to abstract – that is, separate or fuse – the three subjects of experience (the world, the human person, and God). It also calls for the integration in the concept of experience of a deeper account of the symbolic character of finite being as gift, of the role that the human spirit (as life, mind, and freedom) plays in the unfolding of reality’s meaning, and of a perception of time organic with eternity. The overcoming of this abstraction ingrained in the modern concept of experience also depends on a non-mechanistic perception of the human body (McNamara 2022: xxv, 94–158; alternative views in Russell et al. 2002: 327–416; Barrett 2011) that, on the one hand, can articulate the difference between God and finite being while keeping in mind the analogical gift-character of divine and finite being, and, on the other hand, can express the mystery that divine and human persons exist only in communion and not as individual selves (see, for example, Pope John Paul II 2006; 2014). When all these factors are considered, it will be possible to realize that human experience, in its constitutive engagement with truth, remains open to the unforeseeable divine revelation that can clarify its meaning and correct its ambiguities. Showing how divine revelation overabundantly fulfils and preserves human experience – without being absorbed by it – is a task for the reflection on Christian experience.
