“Life is an end in itself, and the only question as to whether it is worth living is whether you have had enough of it.”

The Myth of Sisyphus and other essays by Albert Camus, An Absurd Reasoning : Absurdity and Suicide p. 3 (1942, 1955)
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.

Context: I wished hard, but I didn't pray. I had developed a certain distrust of organized religion growing up, but I felt I had the capacity to be a spiritual person, and to hold some fervent beliefs. Quite simply, I believed I had a responsiblity to be a good person, and that meant fair, honest, hardworking, and honorable. If I did that, if I was good to my family, true to my friends, if I gave back to my community or to some cause, if I wasn't a liar, a cheat, or a thief, then I believed that should be enough. At the end of the day, if there was indeed some Body or presence standing there to judge me, I hoped I would be judged on whether I had lived a true life, not on whether I believed in a certain book, or whether I'd been baptized. If there was indeed a God at the end of my days, I hoped he didn't say, "But you were never a Christian, so you're going the other way from heaven." If so, I was going to reply, "You know what? You're right. Fine."
