“Man must smash to bits his stolen, contrived Christian faith through powerful, enormous suffering of the heart, through an amazement that cannot be rejected. Through this, man becomes very small and despicable in his own eyes.”

Context: The analysis of the moral man through his actions, and of the intellectual man through his productions, seems to me calculated to form one of the most interesting parts of the sciences of observation, applied to anthropology.

Context: Religion is a great force — the only real motive force in the world; but what you fellows don't understand is that you must get at a man through his own religion and not through yours. Instead of facing that fact, you persist in trying to convert all men to your own little sect, so that you can use it against them afterwards. You are all missionaries and proselytizers trying to uproot the native religion from your neighbor's flowerbeds and plant your own in its place. You would rather let a child perish in ignorance than have it taught by a rival sectary. You can talk to me of the quintessential equality of coal merchants and British officers; and yet you can't see the quintessential equality of all the religions.
