Existentialism and Human Emotions

“Man is nothing else but what he makes of himself. Such is the first principle of existentialism.”

This is one heavily profound philosophical book. It starts off with Sartre dissecting the idea of what actually does existential philosophy is about. He wonderfully explains the nature of human behaviour from an existential point of view, exploring ideas like despair, anguish, freedom and God. Sartre's style of writing is simple but a bit tangential at times. Overall the book is a great read if you're interested into philosophy and existentialism.
