“The only serious question in life is whether to kill yourself or not.”

“There is but one truly serious philosophical problem and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy. All the rest — whether or not the world has three dimensions, whether the mind has nine or twelve categories — comes afterwards. These are games; one must first answer.”

“It was previously a question of finding out whether or not life had to have a meaning to be lived. It now becomes clear on the contrary that it will be lived all the better if it has no meaning”

“From the moment absurdity is recognized, it becomes a passion, the most harrowing of all. But whether or not one can live with one's passions, whether or not one can accept their law, which is to burn the heart they simultaneously exalt - that is the whole question.”

“The most important thing you do everyday you live is deciding not to kill yourself.”

“I see many people die because they judge that life is not worth living. I see others paradoxically getting killed for the ideas or illusions that give them a reason for living (what is called a reason for living is also an excellent reason for dying). I therefore conclude that the meaning of life is the most urgent of questions.”

“There comes a time in history when the man who dares to say that two and two make four is punished with death. The schoolteacher is well aware of this. And the question is not one of knowing what punishment or reward attends the making of this calculation. The question is that of knowing whether two and two do make four.”
