Albert Camus was known as an Existential writer.Existentialism deals with the value of existence. Existential themes deal with man and the meaning of the world, his identity, man's decision, freedom and anxiety. Existential themes are nothingness, absurdity, faith, choice, and angst. Camus's works revolve around the ideas and methods of Existentialism.

Camus's works like, The Stranger, Myth of Sisyphus, and Caligula are based on the Existential idea of "The Absurd". Camus's other works like The Rebel, The Just Assassins, and The Plague, are based on the Revolts. In The Stranger, Meursault lives by the ideas of Existentialism. Meursault does not believe in regretting one's mistakes, what is done is done and one should just face the consequences; hence Meursault has killed an Arab, but when being prosecuted he does not fight society when they accuse him of murder amongst apathy for his mother's death.

In The Myth of Sisyphus, the idea of suicide is being discussed. Sisyphus is a Greek mythical character who was a conniving man in history, so when Sisyphus commits suicide, he is condemned, by Hades, to be blinded and to roll a boulder up a mountain and then let it roll down the mountain. This punishment proves how seeking truth is just as pointless as rolling a boulder up a mountain and then let it continuously roll down the mountain. Camus shows that if one only searches for truth then there is no point for living, truth is pointless, for there is no truth.
