The reasoning is classic in its clarity. If God does not exist, Kirilov is god. If God does not exist, Kirilov must kill himself. Kirilov must therefore kill himself to become god. That logic is absurd, but it is what is needed.
Albert CamusThe sense of doing good , the satisfaction of being right, the joy of looking favorably upon oneself, dear sir, are powerful levers for keeping us upright and making us progress. On the other hand, if men are deprived of that feeling, they are changed into rabid dogs.
Albert CamusWithout memories, without hope, they lived for the moment only. indeed, the here and now had come to mean everything to them. For there is no denying that the plague had gradually killed off in all of us the faculty not of love only but even of friendship. Naturally enough, since love asks something of the future, and nothing was left us but a series of present moments.
Albert Camus
