Dostoyevsky
'Never in my whole life have I read a more engrossing and elemental work, and at the time I had never read such a long one. It had the effect of a powerful drug, and for a time I was totally absorbed by it. For some time after my return home I refused to read another book, fearing that I might be plunged headlong into the deepest disappointment. For weeks I refused to read anything at all. The monstrous quality of The Demons had made me strong; it had shown me a path that I could follow and told me that I was on the right one, the one that led out. I had felt the impact of a work that was both wild and great, and I emerged from the experience like a hero. Seldom has literature produced such an overwhelming effect on me.'
