Historicization
ELI5
Historicization means that the past doesn't come with a fixed meaning — it only becomes truly "historical" (meaningful, significant) when someone, right now, chooses a goal that makes those past events matter in a particular way.
Definition
Historicization, as it emerges in Sartre's Being and Nothingness, designates the ontological operation by which the For-itself retroactively confers historical meaning upon a sequence of past events through its current free project. The past, qua facticity, is not a storehouse of self-evident meanings waiting to be read off; rather, it remains perpetually "in suspense," acquiring determinate sense only when the For-itself's present projection toward the future takes it up, interprets it, and validates or invalidates it under the light of its current utilitarian or ethical aims. Historicization is thus the moment at which brute factical succession — a series of past relations, acts, or exchanges — becomes History in the full sense: a temporally organized, meaningful narrative that the subject recognizes as bearing on its situation. The example Sartre gives — the United States recovering and revaluing its prior relations with France as a "debt of honor" — illustrates that the same factual past can remain mere chronicle or become historical event depending entirely on the project that appropriates it.
This concept is inseparable from Sartre's broader account of temporality and freedom. The For-itself is the being through which time is constituted as meaningful, because the For-itself is structured as permanent self-distancing: it is never coincident with its past (which is in-itself, fixed, factical) but always ahead of itself toward possibility. Historicization is therefore the name for the exercise of this temporal freedom at the level of collective or inter-subjective meaning — the point at which the nihilating power of the For-itself reaches backward into sedimented relations and makes them signify. It is not an act of arbitrary rewriting but of free constitution: the project provides the evaluative horizon ("debt of honor") within which past events acquire their truth. Meaning is not discovered in the past; it is conferred upon it — which is what makes freedom the "original constituent of both temporal structure and historical meaning."
Place in the corpus
Within the source jean-paul-sartre-hazel-barnes-being-and-nothingness-an-essay-on-phenomenological, historicization occupies a specific junction between the concepts of facticity, temporality, freedom, and project. Facticity — all that the subject inherits as unchosen, brute, past givenness — provides the raw material that historicization works on. Temporality supplies the structural condition: because the For-itself ecstatically relates past, present, and future, the past is never sealed but remains open to reappropriation by the present project. Freedom is the active force: historicization is freedom's operation on factical sequence, the move that converts chronicle into History. The concept is thus a specification of how freedom and facticity interact at the level of collective temporal meaning, rather than merely individual biography.
In relation to the cross-referenced canonical concepts, historicization sits at the intersection of Phenomenology and Subjectivity: it enacts the phenomenological claim that meaning is always constituted by a subject (the For-itself as intentional consciousness), while specifying that this constitution works temporally and retroactively rather than through a present intuition. It is distinct from mere Identification (which concerns the subject's relation to an image or signifier in the Other) but shares with it the retroactive, constitutive structure — meaning comes after the fact, not before. In Lacanian terms, one might note (as an inference) that historicization resonates with après-coup (Nachträglichkeit): the logic by which earlier events receive their traumatic or meaningful charge only from a later moment. Sartre reaches this retroactive structure through phenomenological ontology and freedom rather than through the signifier, which marks the precise limit at which phenomenology (as critiqued in the corpus) stops short of accounting for the unconscious dimension of temporal constitution.
Key formulations
Being and Nothingness: An Essay on Phenomenological Ontology (p.500)
When in the light of its utilitarian projects, it recovers the previous relations of the United States with France and gives to them the meaning of the paying of a debt of honor by Americans to France, then it becomes historical.
The phrase "recovers... and gives to them the meaning" is theoretically loaded because it makes explicit the two-stage retroactive structure at the heart of historicization: first a taking-up (recovery) of factical past relations, then a bestowal (giving) of meaning — under the explicit frame of a "utilitarian project," showing that it is the present free projection, not the past itself, that is the constitutive agent of historical sense.
