Then came four years in the Siberian prison, followed by a few years of enforced military service. His health actually grew better under the cruel regime of the prison, which is not difficult to understand, for even a cruel regime is better than none at all, and Dostoevski never had the slightest notion of how to take care of himself. At what time his epilepsy began is obscure, but this dreadful disease faithfully and frequently visited him during his whole adult life. From a curious hint that he once let fall, reenforced by the manner in which the poor epileptic in "The Karamazov Brothers" acquired the falling sickness, we cannot help thinking that its origin came from a blow given in anger by his father. Dostoevski was enormously interested in his disease, studied its symptoms carefully, one might say eagerly, and gave to his friends minute accounts of exactly how he felt before and after the convulsions, which tally precisely with the vivid descriptions written out in his novels. This illness coloured his whole life, profoundly affected his character, and gave a feverish and hysterical tone to his books. Dostoevski had a tremendous capacity for enthusiasm. As a boy, he was terribly shaken by the death of Pushkin, and he never lost his admiration for the founder of Russian literature. He read the great classics of antiquity and of modern Europe with wild excitement, and wrote burning eulogies in letters to his friends. The flame of his literary ambition was not quenched by the most abject poverty, nor by the death of those whom he loved most intensely. After his first wife died, he suffered agonies of grief, accentuated by wretched health, public neglect, and total lack of financial resources. But chill penury could not repress his noble rage. He was always planning and writing new novels, even when he had no place to lay his head. And the bodily distress of poverty did not cut him nearly so sharply as its shame. His letters prove clearly that at times he suffered in the same way as the pitiable hero of "Poor Folk." That book was indeed a prophecy of the author's own life. It is impossible to exaggerate the difficulties under which he wrote his greatest novels. His wife and children were literally starving. He could not get money, and was continually harassed by creditors. During part of the time, while writing in the midst of hunger and freezing cold, he had an epileptic attack every ten days. His comment on all this is, "I am only preparing to live," which is as heroic as Paul Jones's shout, "I have not yet begun to fight."
