Temporality
Being and NothingnessTemporality names the For-itself’s way of existing outside itself across past, present, and future. It is neither a universal time that contains human beings nor a succession of self-sufficient moments: it is the internally related, self-surpassing structure through which consciousness bears its past, flees in the present, and projects possibilities. Its unity is real but never finished; human reality temporalizes itself as an incomplete totality that runs after itself and refuses to coincide with itself.
Against time as a sequence
The analysis turns to Temporality after the For-itself has been shown to exceed the instantaneous limits of the Cartesian cogito. Consciousness is already transcended toward value and possibilities, but those possibilities can be its own only through a temporal surpassing. They appear on the horizon of a world made meaningful by the projects directed toward them. A description of time is therefore necessary to clarify the For-itself and, ultimately, consciousness’s original relation to being.
Past, present, and future cannot be collected as independent givens or arranged as an infinite series of “nows.” The past is no longer, the future is not yet, and an instantaneous present has no duration; treated as separate items, the series seems to vanish into nothingness. The alternative is to approach Temporality as an organized totality whose secondary structures acquire their meaning from the whole. The three dimensions are not detachable parts but moments of an original synthesis, and any description of one must keep in view its dependence on the others.
The unity that disperses itself
Temporality is not a container in which instants are placed and later reunited. Nor can it be reduced to irreversible succession considered on its own, since succession alone would not explain how there is one time. Unity and multiplicity have no priority over one another: Temporality is a unity that multiplies itself, an internal relation at the heart of a being. The before and after become intelligible through one another; the before is before only for a being that is, in its own being, outside itself.
That structure belongs to the For-itself. Temporality is its mode of being insofar as it has to be its being ekstaticly: it temporalizes itself by existing. The For-itself cannot exist except temporally, and no temporal dimension stands alone. Past, present, and future condition one another in a single synthetic form. The present is not ontologically prior, although it is the mould of non-being through which that form is disclosed; the For-itself is its past as something it must be, surpasses that past, and is haunted by its future.
The book calls this mode of being diasporatic. The For-itself holds to itself through one thread while dispersing across the dimensions of nihilation. In contrast, the In-itself has only one dimension of being. With the appearance of nothingness at the heart of being, the For-itself’s relation to itself becomes a dispersed temporal structure rather than the fixed self-identity of a thing.
Duration and incompletion
The account distinguishes this original structure from the dynamic problem of duration. Showing that the For-itself rises according to three temporal dimensions does not yet explain why it becomes past or how a new present arises. The analysis nevertheless establishes that time is not an independently existing law or substance. It is the intra-structure of a being that is its own nihilation: Temporality is not itself a being, but the For-itself exists temporally.
The time of consciousness is human reality temporalizing itself as a totality that is its own incompletion. Nothingness enters that totality as a detotalizing ferment: the For-itself runs after itself and refuses itself at once, surpassing itself toward itself without finding a final limit. For that reason it cannot be confined to an instant. There is no instant at which the For-itself simply is, and Temporality is described as a refusal of the instant rather than a sequence of completed presents.
Temporality in the lived project
The glossary condenses the account into a subjective process through which the For-itself continuously lives its project of nihilating the In-itself. Time does not reside in things as a property: it flows over them, while the For-itself establishes a measure for their duration and self-identity. In this formulation, the For-itself is what it has been in the past, a flight in the present toward what it projects to be in the future.
This description connects Temporality to the broader account of ek-stasis. The For-itself stands out from itself through Temporality, attempting reflection, and its discovery that it has a Self for the Other. Temporality is the first of these three successive ekstases: it nihilates the In-itself through past, present, and future. Its significance is therefore not merely that it locates consciousness in time. It explains how consciousness can be related to its past without being fixed by it, exceed what is given, and make a world intelligible through the possibilities toward which its projects are directed.
