Facticity of the For-itself
ELI5
Even though consciousness is always free and can always move forward, it can never fully escape what it has already been — the past is the one thing consciousness carries without being able to get rid of it, like a shadow it can never outrun.
Definition
The "Facticity of the For-itself" names the ontological paradox whereby the For-itself — Sartre's term for consciousness as pure nihilating nothingness — is nonetheless weighted by a dimension it cannot liquidate: its own past. Sartre's theoretical move is to demonstrate that temporality (Past, Present, Future) is not an extrinsic framework imposed on consciousness from outside, but the very intra-structure of the For-itself's mode of being as self-nihilation. The For-itself comes into existence already-past — birth is not a metaphysical event but an ontological relation of nihilation by which a "before" is first constituted. The Past is precisely that surpassed facticity: what the For-itself has been but is no longer, yet which it cannot escape, since its very structure as for-itself entails that there is always something it has been and must continue to have-been. Facticity is thus the name for the In-itself dimension that clings to the For-itself despite the For-itself's perpetual effort to transcend it.
This is not a contradiction within Sartre's system but its productive tension: the For-itself is condemned to be its own past in the mode of not-being-it. The Past functions as the permanent factical ground — the weight of being — against which the For-itself projects itself toward its future possibilities. Time, on this account, is not a universal container but what Sartre calls the "diasporatic mode of being" of the For-itself: consciousness is always already dispersed across temporal ekstases, each of which is a distinct relation of nihilation to being. The facticity of the For-itself thus marks the irreducible point at which freedom and being intersect — and resist each other — without either term being dissolved into the other.
Place in the corpus
Within the source (jean-paul-sartre-hazel-barnes-being-and-nothingness), the Facticity of the For-itself occupies a pivotal structural position: it is the point where the analysis of freedom is complicated by the analysis of situation and temporality. It extends the core Sartrean account of Consciousness as pure translucent nihilating nothingness by insisting that this very nihilation necessarily produces a factical residue — the Past — that the For-itself must take up as its own even as it transcends it. Against the cross-referenced canonical concept of Consciousness (which in the Lacanian corpus is systematically decentred and constitutively deceived), Sartre's For-itself remains sovereign and translucent — yet the Facticity of the For-itself introduces a structural opacity at the temporal level: the For-itself cannot "see" its own past directly, only take it up through the present movement of surpassal.
The concept is deeply entangled with Nihilation and Negation as cross-referenced canonicals. The Past is not a positive thing that is simply "there" — it is a surpassed facticity, which means it exists for the For-itself only in the mode of internal negation (the For-itself is what it is not, and is not what it is). This aligns structurally with the Lacanian-Freudian account of Negation as constitutive rather than merely privative, and with Lack, insofar as the For-itself's relation to its past is one of constitutive non-coincidence — it forever lacks the identity with its own being that the In-itself enjoys. The concept also resonates with Ekstasis (one of the cross-references), since Past, Present, and Future are themselves the three temporal ekstases through which the For-itself is dispersed. The Facticity of the For-itself is therefore best understood as a specification — within Sartre's phenomenological ontology — of how freedom is always already situated, and how the structure of Lack and Negation manifests at the level of lived temporal existence rather than abstract structure.

It is precisely this surpassed facticity which we call the Past.
The phrase "surpassed facticity" is theoretically loaded because it holds two apparently incompatible determinations in a single nominal complex: "facticity" names the weight of sheer being that the For-itself cannot dissolve, while "surpassed" names the For-itself's constitutive act of nihilation and transcendence — together they capture the structure by which the Past is neither simply retained (In-itself fashion) nor simply cancelled, but perpetually carried forward in the mode of having-been-overcome.
