This is one of my occasional Who Said This? quizzes.
I have been merely oppressed by the weariness and tedium and vanity of things lately: nothing stirs me, nothing seems worth doing or worth having done: the only thing that I strongly feel worth while would be to murder as many people as possible so as to diminish the amount of consciousness in the world. These times have to be lived through: there is nothing to be done with them.
So who said it? No Googling, because that would be immoral, especially if you’re a moral error theorist.
