He asked the question everyone else had forgotten: what does it mean to be? And then joined the Nazi Party. The two facts cannot be separated.

Jean-Paul Sartre

ExistentialistContemporaryFrench

Born Paris

Existence precedes essence. He said it, lived it, and refused the Nobel Prize to prove it.

Connection

Martin Heidegger fundamental ontology reinterpreted Jean-Paul Sartre — Being and Time gave Sartre the vocabulary for Being and Nothingness: facticity and transcendence, authenticity and bad faith. Heidegger later complained that Sartre had humanized, and missed, what Being and Time was about.
