So you see how many puzzles are there in nature, how many blank spots everywhere. But the empty-headed youth coming up to take our place doesn't seem to see the mysteries of existence. He lacks vision and initiative, and I doubt that he - that any of them - have any brains in their heads. What could be more noble, for example, than experimenting on oneself? At their age I would do this: on Thursday I'd drink, all at one go, three and a half liters of beer and vodka mixed. I'd drink it and lie down to sleep without getting undressed and with one thought only - will I wake up in Friday or won't I?
