Flyaway

“I suddenly felt that it was all the same to me whether the world existed or whether there had never been anything at all: I began to feel with all my being that there was nothing existing. At first I fancied that many things had existed in the past, but afterwards I guessed that there never had been anything in the past either, but that it had only seemed so for some reason. Little by little I guessed that there would be nothing in the future either. Then I left off being angry with people and almost ceased to notice them. Indeed this showed itself even in the pettiest trifles: I used, for instance, to knock against people in the street. And not so much from being lost in thought: what had I to think about? I had almost given up thinking by that time; nothing mattered to me. If at least I had solved my problems! Oh, I had not settled one of them, and how many there were! But I gave up caring about anything, and all the problems disappeared.”
― Fyodor Dostoyevsky, The Dream of a Ridiculous Man
