“Sartre expresses the basic tenet of existentialism in this way: Existence precedes essence. In this statement he is taking existentia and essentia according to their metaphysical meaning, which from Plato's time on has said that essentia precedes existentia. Sartre reverses this statement. But the reversal of a metaphysical statement remains a metaphysical statement. With it he stays with metaphysics in oblivion of the truth of Being.”
