B. Reason is inadequate Existentialists oppose reason to arrive at truth because certain universals have to exist which they oppose. Existentialists emphasize passion and will.

The universe was a closed system governed only by chance and natural law.
Man is nothing but a complex electro-chemical machine.

Truth is personal, not propositional or objective. There is no universe other than the universe of individual human subjectivity.
