“Camus [five_questions]said there is only really one serious philosophical question, which is whether or not to commit suicide. I think there are four or five serious philosophical questions:
The first one is: Who started it?
The second is: Are we going to make it?
The third is: Where are we going to put it?
The fourth is: Who's going to clean up?
And the fifth: Is it serious?”

Absurdity and Suicide
The Myth of Sisyphus (1942), An Absurd Reasoning
Context: 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. And if it is true, as Nietzsche claims, that a philosopher, to deserve our respect, must preach by example, you can appreciate the importance of that reply, for it will precede the definitive act. These are facts the heart can feel; yet they call for careful study before they become clear to the intellect. If I ask myself how to judge that this question is more urgent than that, I reply that one judges by the actions it entails. I have never seen anyone die for the ontological argument.

We haven’t any deep understanding of what we’re doing. If we tried to understand what we’re doing, we’d go nutty.
