The Caracal lies on a shelf in its den in the Zoological Gardens quietly licking its fur. I go up and stand near it. It makes a face at me. I come a little nearer, it makes a worse face and raises itself up on its haunches. I stand and look. It jumps down from its shelf and makes as if it intended "going for" me. I move back; the Caracal has exerted a moral influence over me which I have been unable to resist. Moral influence means persuading another that one can make that other more uncomfortable than that other can make oneself.
