Jean-Paul Sartre (Wheaton Lectures)
From Clark and His Critics, published by the Trinity Foundation (page numbers are from the Apple Books e-book).
Perhaps it will not be necessary to quote from Sartre. Existentialism is so blatantly irrationalistic that everyone knows it repudiates all eternal principles. Existence precedes essence, and no predetermined guidelines, either of divine decree or of psychological determination, or of logical principle, restrict or anticipate how existence may produce essence. All is chaos.Gordon H. Clark. “Clark and His Critics.” Apple Books. 69.
