Camus considers that man is confronted with a contradiction between his desire to understand the world and the silence of the world that does not answer his questions. This situation creates a feeling of absurdity in the man who feels foreign to the world and to himself
Camus then proposes two possible attitudes to the absurd: suicide or revolt. Suicide is a way to escape the absurd by giving up life, but Camus rejects it as an easy and unreasonable solution. Revolt is a way of facing the absurd by accepting one's condition without resigning oneself, by living with passion and freedom, by creating human values and solidarity.
But be careful, for Camus revolt is not the same thing as revolution. The revolt is a spontaneous and individual movement that expresses a refusal of injustice and absurdity, without trying to impose a new ideology or a new system. "Revolution is a collective and organized project that aims to transform the world according to a doctrine or utopia, even if it means sacrificing human lives in the name of an ideal. "
Camus criticizes historical revolutions such as the French Revolution or the Russian Revolution, which he accuses of having betrayed the original spirit of revolt and of having generated totalitarian and oppressive regimes. Instead, he defends an ethic of revolt that respects the dignity and freedom of every human being, without giving up the fight against tyranny and oppression.
I have made here only a slight summary of his Philosophy.
