"I had motives for not wanting the world to have meaning; consequently assumed that it had not; and was able without any difficulty to find satisfying reasons for this assumption. The philosopher who finds no meaning for this world is not concerned exclusively with the problem of pure metaphysics; he is also concerned to prove that there is no valid reason why he personally should not do as he wants to.... For myself... The philosophy of meaninglessness was essentially an instrument of liberation, sexual and political."
