Yosef had the second capacity, the classifying. He not only had it, but he knew that he had it; this conviction preserved him in life from many mistakes, and gave a certain balance to his wishes and capacities. He never undertook a thing that for him was impossible. He calculated with himself. And, finally, he had much enthusiasm, which in his case might have been called persistence in science. Having a mind which was fond of examining everything soberly, he wanted to see everything well; but to see well one must know thoroughly. He was unable to guess, he wished to know.

This was why he never learned anything half-way. As a spider surrounds a fly, he surrounded his subject of investigation diligently with a network of thought, he drew it into himself; it might be said that he sucked it out of the place where it was and finally digested it. His thoughts had also a high degree of activity. He desired, a natural attribute of youth. He was free of conceit. Frequently he rejected an opinion accepted by all, specially for this reason, that it had importance behind it. It must be confessed, however, that in this case he endeavored to find everything that was against it; when he did not find enough, he yielded. He had, besides, no little energy in thinking and doing.

All this composed his strength, his weapon, partly acquired, partly natural. We forgot to say that he had in addition two thousand rubles.

When he had estimated these supplies, he betook himself to medicine. But the greater the enthusiasm with which he betook himself to his specialty the more was he disenchanted at first. He wanted to know, but now only memory was required. In that case any man might succeed; at least it was a question of memory and will, not of reason. One needed a memory of the eyes, a memory of the hands; one had to put into the head seriously the first and second and tenth, from time to time like grain into a storehouse. That was well-nigh the work of a handicraftsman; the mental organism gained no profit from these supplies, for it did not digest nor work them over. Nutrition was lacking there. The philosophy of the physical structure of organisms may be compared in subtlety and in immensity of result with all others; but Yosef was only beginning to become acquainted with the organism itself; indications as to whether there existed any philosophy of those sciences were not given him thus far.

But having once begun he had to wade farther. He waded. But the technical side of scientific labor was disagreeable, thankless, full of hidden difficulties and unexpected secrets, frequently obscure, often barely visible, most frequently repelling, always costing labor. One might have said that nature had declared war against the human mind at this stage. Yosef struggled with these moral difficulties, but he advanced. That technic had a gloomy side also in his eye: it had an evil effect morally.

It disclosed the end of life without indicating whether a continuation existed. The veil was removed from death without the least hesitation. All the deformity of that subterranean toiler was exhibited with unconcealed insolence. That which remained of the dead was also a cynical promise to the living. Death appeared to say in open daylight, "Till we meet in the darkness!" This seemed an announcement bearing terrible proofs of the helplessness of man before an implacable, malicious, loathsome, and shameless power. This power when seen face to face, roused in young minds a violent reaction,—a reaction expressed in the following manner: "Let us lose no time, let us make use of life, for sooner or later the devils will take everything!"

In such occupations delicacy of feeling was dimmed by degrees; indifference was degraded to coarseness, ambition to envy, love passed into passion, passion into impulse. Love was like the sun seen through a smoked glass; one felt the heat, but saw not the radiance.

Yosef warded off these impressions; he shook himself free of them, he cast them away, and went forward.

Finally, he had to be true to his principle. He who has confidence in one career has not in another; that which he has chosen seems best to him. In that which Yosef had chosen everything from the time of Hippocrates downward reposed on experience. Seeing, hearing, tasting, smelling, and feeling are the only criteria on which the whole immense structure stands even in our day.

So men believe, especially young men, as the most different in everything from their elders. All that has come to science by ways aside from experience, is doubtful. Each man judges according to his own thought the ideas of others. The hypothesis of anything existing outside of experience, even if true, seems through such a glass frivolous. "Only investigated things have existence. The connection between cause and effect is a necessity of thought, but only in man. History is a chronicle more or less scandalous; law rests on experience of modes of living in society, speculation is a disease of the mind."
