For-itself as Historicizing Agent
ELI5
When you speak or act freely, you don't escape the rules of language or society — you use them, and in doing so you give the world around you a particular shape and moment in history. It's you doing the historicizing, not history doing it to you.
Definition
The "For-itself as Historicizing Agent" designates Sartre's account of how the for-itself (the structure of human consciousness as radical negativity and freedom) is not merely thrown into a pre-given historical world but actively produces historical time by choosing and projecting itself through the socio-linguistic techniques it inherits. The for-itself does not stand outside the grammatical, social, and technical structures that condition it; it takes them up as its situation and, in surpassing them toward its own project, retroactively endows them with historical meaning — a date, a style, a world. The sentence is Sartre's privileged example: abstract grammatical laws (the structural system) are neither obeyed nor broken by the free speaking subject; they are sustained and exceeded in the very act of choosing to say something, so that the social technique "belongs" to the speaker's freedom even as the speaker "belongs" to the technique. Freedom is thus always situated freedom — not freedom from conditioning structures but freedom exercised in and through them, including the constitutive presence of the Other whose look fixes the situation from without.
This formulation is sharply directional: it is the for-itself that historicizes the world, not the world that historicizes the for-itself. The conditioned world — language, techniques, social structures — is the medium through which the for-itself projects itself, and in that projection the world is given temporal depth, meaning, and dating. The concept therefore articulates a particular resolution of the freedom-structure tension: structure (grammar, language, social technique) is real and conditioning, but it is subordinated to the ontological primacy of the free project. The for-itself does not transcend its situation abstractly; it transcends it concretely, by choosing itself within it, and this choice is simultaneously a historicization of the self and of the world it inhabits.
Place in the corpus
This concept appears in jean-paul-sartre-hazel-barnes-being-and-nothingness-an-essay-on-phenomenological and occupies a polemical position relative to any structuralist or determinist account of subjectivity — hence its cross-referencing of Structuralism and Language. Where structuralism (and its Lacanian inheritance) insists that the subject is an effect of the signifying chain — that Language "uses us" rather than being used — Sartre's for-itself insists on the inverse directional priority: the speaking, choosing subject is the agent that animates and historicizes the abstract structural laws it encounters. This is a direct ontological counterproposal to the Lacanian principle that "language is the condition of the unconscious" and that the subject is always already captured within it before it can speak.
In relation to Freedom and Situation, the concept functions as a specification: it is not generic freedom but freedom-as-historicization, freedom as the act by which both the for-itself and the world acquire temporal determination. Against Alienation (in the Lacanian sense), the concept resists the structural irremediability of the subject's dispossession: for Sartre, the for-itself is not permanently eclipsed by the signifying chain but remains the ontological source of worldly dating and historical meaning. The cross-reference to Gaze and Identification is also significant: it is the constitutive presence of the Other (whose gaze and recognizing or misrecognizing identification define the situation) that makes the for-itself's historicizing act socially embedded rather than solipsistic. Sartre thus accepts that subjectivity is never pure self-coincidence — the Other is always already there — but refuses to let that co-presence dissolve the for-itself's status as the agent of historicization rather than its product.

it is by choosing itself and by historicizing itself in the world that the For-itself historicizes the world itself and causes it to be dated by its techniques.
The quote is theoretically loaded because it establishes a double movement — "historicizing itself" and "historicizes the world itself" — that makes the for-itself simultaneously the subject and the source of historical temporality, rather than its object or product; and the phrase "causes it to be dated by its techniques" explicitly anchors this historicization in socio-linguistic and material structures (techniques), showing that freedom does not bypass structure but operates through it to produce historical meaning.
