Ontological Freedom in Jean-Paul Sartre's Being and Nothingness I think I may have found the quote pertaining to universal determinism which would encompass the notion of biological determinism. I am using Sarah Richmond's translation. "Indeed, if we allowed that the question might be determined in the questioner by a universal determinism, it would cease not only to be intelligible but even to be conceivable. In point of fact, a real cause produces a real effect, and a being that is caused is wholly engaged by its cause within positivity: to the extent that it depends on its being on its cause, it cannot contain the slightest germ of nothingness within it; insofar as a questioner must be able to take a sort of nihilating step back to relation to the thing he is questioning, he escapes from the causal order of the world and extricates himself from the glue of being." (Sartre, J.P.; Richmond, S., 1943, 2018, pg. 59)
