"For many have but one resource to sustain them in their misery, and that is to think, “Circumstances have been against me, I was worthy to be something much better than I have been. I admit I have never had a great love or a great friendship; but that is because I never met a man or a woman who were worthy of it; if I have not written any very good books, it is because I had not the leisure to do so; or, if I have had no children to whom I could devote myself it is because I did not find the man I could have lived with. So there remains within me a wide range of abilities, inclinations and potentialities, unused but perfectly viable, which endow me with a worthiness that could never be inferred from the mere history of my actions.” But in reality and for the existentialist, there is no love apart from the deeds of love; no potentiality of love other than that which is manifested in loving; there is no genius other than that which is expressed in works of art."

"You are -- your life, and nothing else."

"Man is condemned to be free; because once thrown into the world, he is responsible for everything he does. It is up to you to give [life] a meaning."

"It answers the question that was tormenting you: my love, you are not 'one thing in my life' - not even the most important - because my life no longer belongs to me because...you are always me."

"Every existing thing is born without reason, prolongs itself out of weakness, and dies by chance."

"In love, one and one are one."

"Freedom is what you do with what’s been done to you."
