From "Notes from the Underground," by Dostoevsky
...In the first place I spent most of my time at home, reading. I tried to stifle all that was continually seething within me by means of external impressions. And the only external means I had was reading. Reading, of course, was a great help--exciting me, giving me pleasure and pain. But at times it bored me fearfully. One longed for movement in spite of everything, and I plunged all at once into dark, underground, loathsome vice of the pettiest kind. My wretched passions were acute, smarting, from my continual, sickly irritability I had hysterical impulses, with tears and convulsions. I had no resource except reading, that is, there was nothing in my surroundings which I could respect and which attracted me. I was overwhelmed with depression, too; I had an hysterical craving for incongruity and for contrast, and so I took to vice.... And so, furtively, timidly, in solitude, at night, I indulged in filthy vice, with a feeling of shame which never deserted me, even at the most loathsome moments, and which at such moments nearly made me curse. Already even then I had my underground world in my soul. I was fearfully afraid of being seen, of being met, of being recognised."
