Sometimes, when I am cross and cannot sleep, I begin an angry contest with the opinions I object to. Into the room they flop, those bat-like monsters of Wrong-Belief and Darkness; and though they glare at me with the daylight faces of bullying opponents, and their voices are the voices that often shout me down in argument, yet, in these nocturnal controversies, it is always my assertions that admit no answer.

I do not spare them; it is now their turn to be lashed to fury, and made to eat their words.
