Henri Bergson

Henri Bergson is presented as a powerful but incomplete thinker of time and memory. His account of duration grants the past a continuing existence and imagines it interpenetrating the present, resisting a picture of experience made from isolated instants. Yet the book argues that this account does not explain the act or structure by which the past is organized, remembered, and made to matter now. Bergson’s importance lies in how sharply his theory reveals the problem of temporal continuity—and how, in the author’s judgment, it leaves that problem unresolved.

The past and the problem of memory

Bergson’s philosophy assigns the past a kind of enduring existence: an event, on passing into the past, does not cease to be but ceases to act, remaining in its place at its date. Duration is, in this account, a multiplicity of interpenetration, with the past continually organized with the present. The book grants the force of this conception, which restores being to the past rather than treating it as simply annihilated. But preserving the past is not yet an explanation of how it can be reborn in memory or haunt present consciousness.

That difficulty sharpens when the past is described as unconscious and inactive. If it has no activity, the book asks, how can it weave itself into present consciousness? If it acts upon the present, does that not make its force present already—and how, then, does the force emanate from the past as past? Bergson’s theory thus supplies an enduring past but leaves obscure the connection that would make this past operative for a remembering subject.

The critique also concerns the kind of being attributed to the past. Bergson’s conception, alongside Descartes’s opposing account, treats the past in isolation from the present. Whether the past is preserved as a kind of household god or held to have been annihilated, the difficulty remains if all bridges to the present have been cut. Against both alternatives, the book insists that a past is never simply isolated in its pastness: it is the past of a present and is bound to the being for whom it is past.

Duration against the instant

Bergson’s position emerges as a reaction against accounts that make time a series of separate instants. In the discussion of temporality, Leibniz, reacting against Descartes, and Bergson, reacting against Kant, are grouped as thinkers who emphasize immanence and cohesion. Bergson’s duration is a melodic organization and a multiplicity of interpenetration rather than a succession assembled out of discrete, self-contained moments. In this respect, he is right to resist the instant: a temporal unity cannot be understood simply by placing isolated points next to one another.

But suppressing the instant does not itself explain temporal organization. The book argues that any organization of a multiplicity presupposes an organizing act. Bergson’s account describes the flow and interpenetration of duration without identifying what unifies that multiplicity. Kant, in this comparison, is right to deny that synthesis is simply given, even as Bergson sees more clearly than Descartes the inadequacy of the isolated instant.

The question is therefore not whether duration flows, but what kind of being can sustain both cohesion and separation. Temporality is described as a unifying relation that also differentiates: before and after are intelligible only as an internal relation within a being that is itself outside itself. Bergson’s description points toward this difficulty, but the book argues that the ontological structure required to resolve it has not been established by the description of duration alone.

The limits of interpenetration

The book calls the past that clings to and penetrates the present in Bergson’s account scarcely more than a rhetorical figure unless a present being exists ek statically in the past. If the past is inactive, it can remain behind; it cannot enter memory merely by being said to interpenetrate the present. The account therefore needs an explanation of the being that endures across time, or of duration itself if duration is what being is.

This challenge extends to the familiar language of interpenetration. If duration contains parts that interpenetrate, those parts seem divisible and isolated in principle; their fusion then requires an unexplained cohesion. If, instead, they are genuinely fused, the theory must explain what makes their organized multiplicity possible. Bergson’s appeal to duration describes a unity that experience presents, but, as the book reads it, does not ground that unity in the structure of consciousness.

The criticism is not that Bergson has failed to notice temporal continuity. It is that continuity, taken as a fact, cannot serve as its own explanation. The author repeatedly returns to the distinction between depicting an enduring flow and accounting for the being through which the past and present belong together. Bergson’s work makes the need for that account unmistakable, while leaving the central ontological question open.

Psychic duration and reflective consciousness

The same tension appears in the book’s treatment of psychic duration. Bergson’s “multiplicity of interpenetration,” the author argues, concerns the psychic state rather than consciousness understood as the For-itself. Psychic states, such as hate, may appear as a unified duration across successive moments; yet the cohesion among those apparently formed “nows” is, on Bergson’s account as presented here, a given intuition rather than a unity derived from consciousness’s own structure.

For the book, this distinction matters because psychic duration is an inert, constituted unity, whereas original temporality belongs to the self-transcending being of the For-itself. Under reflection, consciousness apprehends itself as enduring and a psychic world appears: love or hate can be taken into account as a reason for acting, and the psyche becomes a virtual situation through which the For-itself determines itself. Such psychic temporality is made-to-be; it does not temporalize itself. It may therefore resemble Bergsonian duration, but that resemblance does not make the psychic flow the source of original temporality.

Bergson’s theory consequently serves as both a landmark and a foil. It gives philosophical form to the intuition that the past persists in a lived present and that duration is more than a chain of instants. The book’s counterclaim is that persistence and interpenetration cannot, by themselves, explain how a past belongs to the present or how temporal unity is achieved. That explanation must begin not with duration treated as a self-sufficient fact, but with the being whose existence is temporal.
