Temporality cannot be derived from atemporal being or imposed upon it

Evidence

Thus inasmuch as temporality is at once a form of separation and a form of synthesis, it does not allow itself either to be derived from a non-temporal or to be imposed from without upon non-temporals. — Jean-Paul Sartre, Being and Nothingness, 467

Categorization

• DEFINE: Clarifies why temporality is irreducible: it is simultaneously separation and synthesis, so neither a non-temporal source nor external imposition can produce it.
• XREF: Connects directly to Kant’s ‘I think’ and Husserl’s noema as foils, which Sartre is clearing away to set up his own ekstatic temporality — the backdrop Beauvoir inherits. — connects to: Temporality is the necessary horizon for the for-itself’s transcendence; Temporal unity cannot be rebuilt from atemporal substances; Temporality exists only as the intra-structure of the For-itself, which temporalizes itself. — Jean-Paul Sartre, Being and Nothingness: An Essay on…, 471 (+4 more)
• yield-rescued: below the book’s yield-target cutoff, included anyway for connecting to: Temporality is the necessary horizon for the for-itself’s transcendence; Temporal unity cannot be rebuilt from atemporal substances; Temporality exists only as the intra-structure of the For-itself, which temporalizes itself. — Jean-Paul Sartre, Being and Nothingness: An Essay on…, 471 (+4 more)
