Dostoevsky?s forgotten lesson about human nature

?I am a sick man. I am a spiteful man. I believe my liver is diseased. However, I don?t consult a doctor for it, though I respect medicine and doctors. No, I refuse to consult a doctor from spite. I am well aware that I cannot ?pay back? the doctors by not consulting them, and that I am only injuring myself. But still, if I don?t consult a doctor, it is from spite. My liver is bad. Well let it get worse!?
? Fyodor Dostoevsky, ?Notes from the Underground,? 1864
