"And then--it's queer logic!" grumbled the student as he put on his nightshirt. "The ideas which you so dislike, which are so ruinous for the young are, according to you, the normal thing for the old; it's as though it were a question of grey hairs. . . . Where do the old get this privilege? What is it based upon? If these ideas are poison, they are equally poisonous for all?" "Oh, no, my dear soul, don't say so!" said the engineer with a sly wink. "Don't say so. In the first place, old men are not dilettanti. Their pessimism comes to them not casually from outside, but from the depths of their own brains, and only after they have exhaustively studied the Hegels and Kants of all sorts, have suffered, have made no end of mistakes, in fact--when they have climbed the whole ladder from bottom to top. Their pessimism has both personal experience and sound philosophic training behind it. Secondly, the pessimism of old thinkers does not take the form of idle talk, as it does with you and me, but of _Weltschmertz_, of suffering; it rests in them on a Christian foundation because it is derived from love for humanity and from thoughts about humanity, and is entirely free from the egoism which is noticeable in dilettanti. You despise life because its meaning and its object are hidden just from you, and you are only afraid of your own death, while the real thinker is unhappy because the truth is hidden from all and he is afraid for all men. For instance, there is living not far from here the Crown forester, Ivan Alexandritch. He is a nice old man. At one time he was a teacher somewhere, and used to write something; the devil only knows what he was, but anyway he is a remarkably clever fellow and in philosophy he is A1. He has read a great deal and he is continually reading now. Well, we came across him lately in the Gruzovsky district. . . . They were laying the sleepers and rails just at the time. It's not a difficult job, but Ivan Alexandritch, not being a specialist, looked at it as though it were a conjuring trick. It takes an experienced workman less than a minute to lay a sleeper and fix a rail on it. The workmen were in good form and really were working smartly and rapidly; one rascal in particular brought his hammer down with exceptional smartness on the head of the nail and drove it in at one blow, though the handle of the hammer was two yards or more in length and each nail was a foot long. Ivan Alexandritch watched the workmen a long time, was moved, and said to me with tears in his eyes: "'What a pity that these splendid men will die!' Such pessimism I understand." "All that proves nothing and explains nothing," said the student, covering himself up with a sheet; "all that is simply pounding liquid in a mortar. No one knows anything and nothing can be proved by words." He peeped out from under the sheet, lifted up his head and, frowning irritably, said quickly:
