The further one advances in life, the more does life offer things that can give one a good reason for enjoying and amusing oneself. And the first thing that can make one smile is seeing how everybody is running after his own interests: how a man finds his way along devious routes, how he knocks another person down in order to go forward himself, how he pushes another from behind, and how he silences the next one. Is there anything that we cannot find in human nature? Biting, kicking, and fighting, it is all there. There is nothing of the animal nature that is not in the human being; man even excels the animal. All this, however, only makes one smile; the laughter comes afterwards, when one can see where it all ends. If one is capable of seeing all the various endings, in the end there will be laughter.
