Kant’s critical philosophy formulated one of the fundamental questions of modern thought with particular precision: How is experience possible? This question investigates, prior to the content of individual experiences, the conditions that make any experience possible at all. The forms of sensibility, the categories of the understanding, and the a priori structure of the subject are not, for Kant, elements added to experience afterward; they are the conditions under which experience can be constituted as experience. For this reason, what Kant calls the “transcendental” investigation does not mean examining another reality located beyond experience. The transcendental concerns the conditions that make experience possible but are not themselves derived from empirical experience.
Bergson’s relation to Kant involves both proximity and rupture precisely at this point. The originality of Deleuze’s interpretation of Bergson also begins here. Bergson does not simply accept experience as immediately given and restrict himself to describing its content; he investigates the pure tendencies, directions, and distinctions that produce the experience that appears before us. In this respect, methodological intuition resembles a transcendental movement in the Kantian sense: it begins from experience but moves beyond what experience immediately presents in order to reach its conditions. Yet the conditions Bergson seeks differ fundamentally from Kant’s. Kant investigates the general and formal conditions of every possible experience, whereas Bergson asks under what conditions a singular, real, and concrete experience has become this particular experience.
This difference is not minor. There is a distinction powerful enough to alter the very object of philosophy between the “conditions of possible experience” and the “conditions of real experience.”
From Possible Experience to Real Experience
Kant’s method seeks to determine universally valid structures behind the diversity of experience. Space and time are not properties of any particular experience; they are the general forms of sensible experience. Similarly, the categories of the understanding are not learned from specific objects; they constitute the conditions under which objects can be thought within experience. Kant therefore establishes a transcendental framework that remains valid regardless of the content of experience. It is precisely through this generality that the framework explains the possibility of experience.
For Bergson, the problem is that this generality remains insufficient for explaining the specificity of concrete experience. If a condition applies in the same form to all possible experiences, can it explain why this experience has occurred in exactly this way rather than another? Real experience is not simply an instance of general conditions. Every experience emerges through its own duration, quality, internal differentiation, and mode of becoming. Philosophy must therefore ask not only, “Under what general conditions is experience possible?” but also, “What are the conditions specific to this experience itself?”
The transformation that Deleuze identifies in Bergson becomes clear here. Transcendental inquiry is preserved, but its form changes. Transcendental conditions are no longer conceived as universal forms that frame all possible experience in advance, but as tendencies and differences that produce real experience. The transcendental thus ceases to stand above experience as a structure and moves closer to the genesis of experience itself. The distance between condition and conditioned narrows.
For this reason, Bergson’s orientation should not be confused with empiricism. Returning to real experience does not mean merely “accepting whatever is given to us.” On the contrary, it requires recognizing that immediately given experience is already a mixed, organized result in which different tendencies are intertwined. The task of intuition is to dissolve this mixture, determine which pure directions are entangled within a singular experience, and trace experience back to the conditions of its own formation.
The Difference Between the Transcendental and the Transcendent
An important distinction in Kantian terminology must be preserved here: the transcendental and the transcendent are not the same. Transcendence refers to a level of being conceived beyond the field of experience. When one thinks of a being such as God as existing beyond possible experience, one is dealing with transcendence. Transcendental analysis, by contrast, does not abandon experience; it investigates the conditions of its possibility.
To describe Bergsonian intuition as transcendental therefore does not mean reducing it to mystical apprehension. Intuition does not leave experience in order to discover another reality. It moves beyond the visible and empirical form of experience but ultimately returns to the conditions that produce that very experience. In other words, it exceeds experience without abandoning the world; it attempts to grasp more deeply the movement through which the world is constituted.
This feature reveals both Bergson’s proximity to Kant and the point at which he departs from him. Kant’s transcendental conditions are a priori structures that allow the subject to constitute experience. The Bergsonian transcendental increasingly shifts away from the structure of the subject toward the movement of life and reality itself. Conditions are no longer merely the forms of the knowing subject; they become the conditions of reality’s own differentiation. The philosophical center of gravity shifts from how the subject constitutes the world to how the world and experience themselves come into being.
For Deleuze, therefore, it would be inaccurate to say that Bergson simply rejects Kant. Bergson inherits the critical problem opened by Kant but changes its limits. Critique now means not merely determining the limits of knowledge but tracing thought back to the level on which concrete experience is produced.
The Distinction Between What Is and What Is in Principle
To understand this transformation, the distinction between en fait and en droit, which becomes important in Deleuze’s reading of Bergson, is decisive. Roughly speaking, en fait refers to what actually occurs, while en droit refers to the pure level that makes it possible. Yet “in principle” should not be understood here as a moral norm. The issue is the distinction between how experience actually appears and the pure level of tendencies that constitutes it.
Everyday experience usually presents us with mixtures. Perception, memory, sensation, matter, and thought are not encountered as completely separated realities. Within experience, they are intertwined in specific proportions and relations. If philosophical analysis merely describes this mixture, it cannot reach the structure of its genesis. Bergsonian intuition investigates which pure tendencies are present within the actually given mixture and reconstructs experience from the perspective of those tendencies.
Kant’s method also seeks a level more fundamental than empirical experience, but the level it reaches consists of universal structures. Bergson, by contrast, searches for the difference proper to the singular experience itself. In Deleuze’s interpretation, the meaning of the transcendental therefore changes: it moves from generality toward singularity, from structure toward tendency, and from possible experience toward real experience.
What matters here is that the conditions of real experience should not constitute a field entirely broader than experience itself. If the conditions bear no internal relation to what they condition, the explanation once again becomes abstract. The Bergsonian approach seeks the condition not outside experience as an alien mold, but within the movement of differentiation active in its genesis. A condition is not a form imposed upon experience from elsewhere; it is the tendency from which experience itself develops.
Between Representation and Presence
Another dimension of the difference between Kant and Bergson appears in the problem of representation. Experience often presents us not with the pure presence of the object but with a processed and organized representation of it. The meaning contained in the French word représentation—“making present again”—is important here. Representation is a mode of appearance organized under particular conditions and differs from the pure existence of the object itself.
Bergsonian intuition therefore does not simply record what is directly given. Empirical experience, which initially appears immediate, is itself already the result of various distinctions, relations of utility, and perceptual organizations. Intuition goes behind this apparent immediacy in order to investigate the object’s own internal difference. In this sense, intuition exceeds the visible form of experience not in order to move away from experience but in order to approach it more closely.
One of the important formulas in Deleuze’s interpretation of Bergson acquires its meaning precisely here: the immediate must be sought in the identity between the thing itself and the difference proper to it. To truly grasp something is not simply to list the external properties that distinguish it from other things; it is to understand through what difference that thing is formed within itself.
Knowledge thus moves from external classification toward internal differentiation. This also changes the status of the concept. A concept is no longer valuable merely because it is broad enough to apply to many different objects. On the contrary, Bergsonian precision requires the production of a concept adequate to its object. The more general a concept is, the more powerful it is not necessarily; generality may sometimes become a form of impoverishment that erases the concrete difference of the object.
The Limit of Kant’s Copernican Revolution
Kant’s famous Copernican Revolution argues that rather than knowledge passively conforming to the object, the object’s capacity to be experienced is conditioned by the cognitive structures of the subject. The object therefore becomes the object of knowledge not in terms of how it is in itself, but in terms of how it can appear under the conditions of our experience. This transformation constitutes one of the most powerful ruptures in modern epistemology.
Bergson’s movement proceeds in another direction. In Deleuze’s interpretation, Bergson moves beyond asking how experience is conditioned by the subject and begins to investigate the movement from which the distinction between subject and object itself emerges. If sensation and understanding, memory and perception, interiority and exteriority are not fixed distinctions given in advance, philosophy cannot restrict itself to explaining how these faculties function. It must also think the processes through which such distinctions are produced.
The Bergsonian transcendental therefore becomes increasingly non-formal. Along the line opened by Deleuze, conditions become material, singular, and tendential. They are material because they are not empty forms standing outside real experience. They are singular because they do not provide the same general schema for all possible experiences. They are tendential because they express directions of becoming rather than static structures.
This change does not so much abandon Kant’s critical project as carry it toward a more radical question: is it possible to think not only the conditions that make experience possible, but also how those conditions themselves come into being?
Waiting for the Sugar to Dissolve
A remarkably simple example Bergson uses in Creative Evolution makes this entire discussion concrete: in order to obtain sugar water, one must wait for the sugar to dissolve. The philosophical importance of this example lies in the fact that conceptually knowing in advance that an event will occur does not abolish the real time of its becoming. We may know that the sugar will dissolve, but we must nevertheless live through the duration of its dissolution. Waiting is not a subjective addition external to the event; it belongs to the event’s mode of realization.
Here real experience separates itself from possible experience. What is possible can be thought in advance at the conceptual level; what is real occurs within duration. Reality is not simply the realization of what the concept has already calculated. Time is the field of novelty and unpredictable differentiation. To investigate the conditions of real experience therefore cannot mean constructing a structure that excludes time.
The importance of Bergsonian intuition follows from this. Intuition attempts to follow the movement of reality without freezing it within the stability of the concept. Precision does not mean being able to deduce the entire future of an event in advance; it means developing a thought adequate to the event’s own mode of becoming.
Philosophical precision must therefore be distinguished from closure. A system is not necessarily more precise because it is more complete; on the contrary, if it excludes reality’s capacity to produce novelty, its completeness may become its weakness.
A Philosophy of Real Experience
Kant’s great contribution to philosophy was to make it necessary to think the conditions of experience. Bergson’s movement, radicalized by Deleuze, carries that question back into concrete experience itself. The question is no longer only “How is experience possible?” but “How does this real experience come into being?”
The method of philosophy changes accordingly. Singular tendencies take the place of universal forms, internal differences replace external oppositions, and open-ended investigations replace completed systems.
Bergson’s departure from Kant is therefore not simply a return to empiricism. If it were, Bergson would have to remain confined to experience as it is given. Intuition does the opposite: it exceeds experience in order to reach its conditions. Yet this movement does not abandon experience in favor of an independent transcendent realm. After determining the pure tendencies underlying experience, it returns to concrete experience and attempts to grasp it within its own genesis.
For Deleuze, an important shift in philosophy takes place here. Conditions are no longer applied to conditioned experience from above; they begin to be derived from the genesis of experience itself. Rather than explaining the world according to conceptual structures prepared in advance, thought approaches the world through its own movement of differentiation.
Bergsonian transcendental thought therefore does not eliminate Kant’s critical question; it relocates it onto another level.
Kant taught philosophy to ask about the conditions of experience. The path opened by Bergson asks how close those conditions can come to experience itself. This is not merely a technical distinction between two philosophers. It directly changes the object of philosophy: a transition from the general structure of possible worlds to the singular becoming of the world in which we actually live.
