And he knew, also, what the old man was thinking as his tears flowed, and he, Rieux, thought it too: that a loveless world is a dead world, and always there comes an hour when one is weary of prisons, of one's work, and of devotion to duty, and all one craves for is a loved face, the warmth and wonder of a loving heart.
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.

All those books barely read, those friends barely loved, those cities barely visited, those women barely possessed! I went through the gestures out of boredom or absent-mindedness.

In fact, it comes to this: nobody is capable of really thinking about anyone, even in the worst calamity. For really to think about someone means thinking about that person every minute of the day, without letting one’s thoughts be diverted by anything- by meals, by a fly that settles on one’s cheek, by household duties, or by a sudden itch somewhere. But there are always flies and itches. That’s why life is difficult to live.
