Problem:
"Existentialism Is a Humanism" by Jean-Paul Sartre (1946)
From the Christian side, we are reproached as people who deny the reality and seriousness of human affairs. For since we ignore the commandments of God and all values prescribed as eternal, nothing remains but what is strictly voluntary. Everyone can do what he likes, and will be incapable, from such a point of view, of condemning either the point of view or the action of anyone else.
