And indeed a bird is so made that it must fly, collect food, and build a nest, and when I see that a bird does this I have pleasure in its joy. A goat, a hare, and a wolf are so made that they must feed themselves, and must breed and feed their family, and when they do so I feel firmly assured that they are happy and that their life is a reasonable one. Then what should a man do? He too should produce his living as the animals do, but with this difference, that he will perish if he does it alone; he must obtain it not for himself but for all. And when he does that, I have a firm assurance that he is happy and that his life is reasonable. But what had I done during the whole thirty years of my responsible life? Far from producing sustenance for all, I did not even produce it for myself. I lived as a parasite, and on asking myself, what is the use of my life? I got the reply: “No use.” If the meaning of human life lies in supporting it, how could I⁠—who for thirty years had been engaged not on supporting life but on destroying it in myself and in others⁠—how could I obtain any other answer than that my life was senseless and an evil?⁠ ⁠… It was both senseless and evil.
