Everything Has Been Figured Out Except

Attributed to Sartre and most credibly linked to his Essays in Aesthetics (originally published in French as Situations; republished by Open Road Media, 2012, p. 13), though no primary source has been independently verified chapter and verse. The sentiment is consistent with the central tension of Sartre's existentialism: humanity has accumulated vast knowledge in science, philosophy, and technology, yet the question of how to live — authentically, freely, and with responsibility — remains perpetually open for each individual to answer through action rather than inherited formula. The quote is recorded as "Attributed" in the database.
