Freedom (Sartrean)
ELI5
Sartrean freedom means that, unlike a rock or a table that simply is what it is, a human being is always in the process of choosing and making itself — you have no fixed nature, so you are always responsible for what you do, even though you're always stuck in a situation you didn't fully choose and always seen by others in ways you can't control.
Definition
Sartrean freedom, as it appears in Being and Nothingness, is not a property the for-itself possesses alongside other properties but the very ontological structure of human reality as such. Because existence precedes essence, the for-itself has no pre-given logical nature (contra Leibniz's Adam defined by his essence): it is nothing but the perpetual upsurge toward self-chosen ends, constituted by an "ekstatic temporalization" in which past, present, and future are held together as a Gestalt. Freedom is therefore not the ability to choose between pre-given options but the very mode of being by which the for-itself nihilates the given — the factical situation — and surges toward its possibilities. This means freedom cannot be measured in degrees: no situation suppresses or amplifies it, since the situation itself is constituted as such only by a free surpassing. Freedom and facticity are not opposites but co-constitutive poles of the single ontological structure Sartre calls "situation."
Crucially, Sartrean freedom is not sovereign self-sufficiency. Because the for-itself is always already exposed to the Look of the Other, its freedom is perpetually haunted by being-for-others — the dimension of existence in which it is fixed, objectified, and rendered opaque. Hate, as the project of destroying the Other to abolish this alienation, reveals freedom's structural trap: even successful annihilation of the Other leaves one's being-for-others irremediably sedimented in the past. Freedom thus cannot escape the other's gaze by its own effort; it can only take up its situation — including its alienated objectification — as the very terrain within which it projects itself. Sartrean freedom is accordingly absolute in structure but never pure: it is always situated, always entangled with facticity, and always shadowed by the irreducible exteriority that being-for-others introduces into the heart of the for-itself.
Place in the corpus
This concept lives entirely within the single source jean-paul-sartre-hazel-barnes-being-and-nothingness-an-essay-on-phenomenological, where it functions as the architectonic principle unifying the text's three major ontological structures: being-in-itself, being-for-itself, and being-for-others. Sartrean freedom is the positive face of the for-itself's nihilating structure — the same structure that, in its relation to the Other, generates being-for-others and, in its encounter with the Other's Look, generates alienation. It thus stands in close dialogue with the cross-referenced canonical concepts: it is what the for-itself is insofar as it is not yet fixed — yet being-for-others (the canonical concept synthesized here as a cross-ref) names exactly the dimension in which freedom is perpetually objectified and partially arrested by the Other's gaze. Alienation in the Lacanian-Sartrean interface would name the inevitable cost of this exposure: freedom constitutes itself only through a situation already inhabited by others whose Look it cannot neutralize.
Relative to the other cross-referenced canonicals, Sartrean freedom sits at an instructive distance from the Lacanian Subject. Where the Lacanian subject is constitutively split, passive, and produced as a vanishing effect of the signifying chain, Sartrean freedom names a radical, if always situated, self-projection — a for-itself that is the source of its own nihilation rather than an effect of the Other's signifying chain. The cross-ref to the big Other is likewise telling: for Sartre there is no symbolic Other that pre-structures the field of possibility; freedom is originarily unconditioned by any such order, even if it is always conditioned by facticity. Singularity maps onto the Sartrean fundamental project — the irreplaceable Gestalt of an individual's original choice of ends — while Identification and Hate as Ontological Failure mark the limits at which Sartrean freedom encounters its own impossibility: the for-itself that hates consents to being only for-itself, refusing the other's constitutive role, only to discover that this refusal cannot undo what being-for-others has already deposited.
Key formulations
Being and Nothingness: An Essay on Phenomenological Ontology (page unknown)
there is no situation in which the given would crush beneath its weight the freedom which constitutes it as such—and that conversely there is no situation in which the for-itself would be more free than in others.
The quote is theoretically loaded because it asserts a strict ontological equivalence across all situations: the phrase "the freedom which constitutes it as such" reveals that freedom is not something that exists alongside the situation but is the very act by which a situation is constituted as a situation at all — making freedom and facticity inseparable co-conditions rather than competing forces, and foreclosing any empirical or comparative measure of freedom.
