For-itself

The For-itself (être-pour-soi) is Sartre's central ontological category for conscious human reality, defined by its constitutive non-coincidence with itself. Unlike the In-itself (être-en-soi)—which simply is what it is, in opaque self-identity—the For-itself "is what it is not and not what it is": it exists only as perpetual flight from itself, as presence-to-itself rather than as a thing. This structural non-identity is not a deficiency imposed from outside but is the very mode of being of consciousness: the For-itself is "the being which determines itself to exist inasmuch as it can not coincide with itself," sustained by an immanent nothingness or nihilation at its core. Because its being is always at a distance from itself—stretched across temporal ekstases of past, present, and future—the For-itself is process rather than substance, continuously choosing to project itself toward possibilities it is not yet and surpassing the facticity it has been.

This structural non-coincidence grounds several derived features. First, freedom: the For-itself "is free to choose its way of being" precisely because it is never fixed in the manner of an in-itself. Second, lack and desire: "the For-itself is the foundation of itself as a lack of being," constitutively oriented toward a future self-completion (the impossible fusion of for-itself and in-itself) that it can never achieve. Third, temporality: "temporality is not, but the For-itself temporalizes itself by existing"—time is not a container but the ekstatic mode of the For-itself's being. Fourth, embodiment: the For-itself is not a soul in a body but is its body, since body just is the contingent form assumed by the necessity of the For-itself's factical engagement in the world. Finally, the For-itself requires being-for-others as its condition: "being-for-others appears as a necessary condition for my being-for-itself," since the Other's look can fix the For-itself's perpetual flight into an in-itself-like object.

In the corpus, all occurrences derive from a single source: Sartre's Being and Nothingness (1943) together with Hazel Barnes's translator's introduction. There is accordingly no cross-author evolution to track, but there is significant internal development within the text itself. Barnes's introduction (Occurrences 1–3) presents the For-itself in summary and thematic terms—as "free to choose its way of being," as "process rather than entity," and as constitutively embodied—functioning as an orientating overview for the reader. The philosophical architecture visible in the introduction is then elaborated with increasing technical precision in the body of the work.

In Part Two of Being and Nothingness (Occurrences 7–15), Sartre moves from the preliminary contrast with the In-itself to a fully developed structural analysis. The For-itself is shown to be grounded in nothingness as an "impalpable fissure," constituted as lack (Occurrence 8), as the being of self-reference (Occurrence 9), and as the ontological condition for past, present, and future as ekstatic modes of a single temporalizing act (Occurrences 10–15). This represents the most technically dense phase of the concept's presentation, where the For-itself's formal features—non-coincidence, self-nihilation, projection—are individually derived.

Parts Three and Four (Occurrences 16–28) apply the concept outward: to the problem of Other Minds (the For-itself needs the Other to be a fully constituted self-consciousness), to the body (the For-itself is its body, not a substance attached to one), to situation and freedom (freedom is the very being of the For-itself, which is condemned to be free in any situation), and finally to appropriation, play, and the fundamental project (the impossible dream of becoming an In-itself-For-itself, or God). This arc traces a movement from formal ontological analysis toward a concrete existential anthropology grounded in the same structural core. No later commentators appear in the corpus to modulate or challenge Sartre's own formulations, so the evolution is entirely internal to Being and Nothingness.

The for-itself is the being which determines itself to exist inasmuch as it can not coincide with itself.

This is Sartre's most compressed technical definition of the For-itself: its mode of being is defined entirely by the impossibility of self-coincidence, making non-identity the positive ontological structure of consciousness rather than a lack.

Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (page unknown)

the being of for-itself is defined, on the contrary, as being what it is not and not being what it is.

This formulation establishes the dialectical opposition between For-itself and In-itself at the most fundamental level, and it recurs throughout Being and Nothingness as the master formula for consciousness, bad faith, and freedom alike.

Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (p.86)

The for-itself is the foundation of itself as a lack of being; that is, it determines its being by means of a being which it is not.

Pivotal for linking the For-itself to desire and transcendence: the structural lack that constitutes it is not contingent suffering but the ontological form through which desire, intentionality, and the cogito's self-surpassing all become intelligible.

Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (p.135)

Temporality is not, but the For-itself temporalizes itself by existing.

This formulation shows that temporality is not a container or property but the For-itself's own mode of being: time exists only because consciousness perpetually flees itself across past, present, and future.

Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (page unknown)

The For-itself is a temporalization. This means that it is not but that it 'makes itself.'

Concisely captures the anti-substantialist core of the For-itself: it has no fixed nature or essence but is purely self-constituting process, which grounds both radical freedom and the impossibility of a given human nature.

The young woman on a date who lets her hand rest inertly in her companion's, neither withdrawing it nor acknowledging the advances — exploiting the shuttle between for-itself and for-others to avoid committing herself (case_study)

Cited by Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (page unknown). Sartre uses this case to show how bad faith exploits the ontological gap between being-for-itself (transparent, transcendent self-consciousness) and being-for-others (fixed object-identity). The woman treats her hand as a thing (in-itself) so as not to confront the free choice the for-itself would require her to make.

The For-itself historicized in the time of Duns Scotus, ignorant of the automobile and airplane (history)

Cited by Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (p.522). Sartre uses this historical example to argue that no technical epoch represents a privation for the For-itself situated within it: because the For-itself always exists in a world that is 'everything it can be' relative to its project, the absence of modern technology does not limit the medieval subject's freedom.

Descartes inventing analytical geometry — determining the state of mathematical knowledge by establishing the axes of coordinates (history)

Cited by Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (page unknown). Sartre invokes Descartes as an illustration that a For-itself is not a nature transported into a historical situation but is absolutely its date: Descartes constitutes both himself and his epoch through his free projective act, making it impossible to ask what he 'would have been' under other conditions.

Tennis player adopting court positions in anticipation of the return shot (other)

Cited by Being and Nothingness: An Essay on Phenomenological OntologyJean-Paul Sartre · 1943 (page unknown). Sartre uses this example to illustrate that the For-itself's present actions are always defined by a future possibility toward which they are oriented: each position on the court has meaning only through the future shot, demonstrating that the For-itself exists as a lack whose meaning is always 'at a distance, down there, outside.'

Within the corpus

Whether the For-itself is constitutively embodied (identical with its body) or whether body and consciousness remain on two 'incommunicable levels' that cannot be united.

• Barnes (introducing Sartre): 'we might more accurately say that the For-itself is its body… If the For-itself were not body simultaneously with consciousness, the idea of objects as instruments would not make sense.' The For-itself and body are identified. — cite: jean-paul-sartre-hazel-barnes-being-and-nothingness-an-essay-on-phenomenological, introduction

• Sartre (in the body analysis): 'Being-for-itself must be wholly body and it must be wholly consciousness; it can not be united with a body.' The lived body and the body-as-object exist on two incommunicable ontological levels, and the For-itself never straightforwardly 'is' the body it touches or sees. — cite: jean-paul-sartre-hazel-barnes-being-and-nothingness-an-essay-on-phenomenological, part 3 chapter 2

  Barnes's summary-identification ('the For-itself is its body') elides Sartre's careful distinction between the body as lived facticity and the body as object-for-others, the conflation of which Sartre himself identifies as the source of pseudo-problems like inverted vision.

Across frameworks

vs Ego Psychology

Lacanian: For Lacan, the Sartrean For-itself's supposed self-transparency and radical freedom are ideological illusions maintained by the imaginary register. The subject is constitutively split (divided subject, $) by its subjection to the signifier and structured by an unconscious that is not a pre-reflective cogito but an Other's discourse. There is no foundational self-presence from which freedom can be exercised; the 'I' that thinks it chooses is itself an effect of the symbolic order.

Ego Psychology: Ego psychology (Hartmann, Kris, Loewenstein) locates a conflict-free sphere of the ego endowed with adaptive, synthetic capacities. Rather than Sartre's absolute freedom of the For-itself, ego psychology posits an autonomous ego that mediates between drive, superego, and reality through neutralized energy — the self is a structured psychic apparatus, not an ekstatic nothingness. Freedom is not ontological but a function of ego strength and adaptation.

Fault line: The deep disagreement is between constitutive lack/non-coincidence (Sartre/Lacan) and adaptive plenitude: whether the subject's core structure is an irreducible void or flight (Sartre, and for Lacan the split), versus a positive agency capable of mastery and synthesis (ego psychology).

vs Humanistic Self Actualization

Lacanian: Sartre's For-itself is defined by constitutive lack and the impossibility of self-coincidence: it can never become what it aims at (the in-itself-for-itself), making the fundamental project structurally doomed and desire perpetually unsatisfied. Lacan radicalizes this: desire is sustained precisely by its non-satisfaction, and there is no telos of plenitude toward which the subject tends — lack is not a deficiency to be overcome but the subject's very condition.

Humanistic Self Actualization: Humanistic psychology (Maslow, Rogers) posits a self with an inherent growth tendency toward actualization of its potentials. The person moves from deficiency toward being-values, from anxiety toward authentic self-expression. The self is not a void but a real structure with positive developmental aims; self-actualization represents a genuine fulfillment rather than a structurally impossible project.

Fault line: Whether the human subject has a positive telos of self-realization (humanistic actualization) or whether it is constituted by an irresolvable lack that no fulfillment can close (Sartrean For-itself, Lacanian desire).

vs Object Oriented Ontology

Lacanian: Sartre's ontology is organized around the For-itself/In-itself divide, in which consciousness (For-itself) is the privileged site of nihilation, meaning-constitution, and temporalization — the In-itself acquires significance only through the For-itself's surpassing of it. Lacan similarly privileges the speaking subject's relation to the signifier over any direct encounter with things, keeping the real inaccessible behind the symbolic.

Object Oriented Ontology: Object-Oriented Ontology (Harman) rejects the privileging of human consciousness (or the subject-signifier relation) in determining the being of objects. Objects have a withdrawn, inexhaustible reality that is not constituted by any for-itself's nihilation or any signifier's naming. The human-world correlation that both Sartre and Lacan presuppose is precisely what OOO dismantles: being is not exhausted by its relation to consciousness or language.

Fault line: The fundamental fault line is correlationism vs. flat ontology: Sartre's For-itself (and Lacan's subject) make meaning, lack, and being-for-consciousness constitutive of how entities show up, while OOO insists objects have a reality independent of and prior to any such relation.
