Violence may well be the only form of human action by which it is possible
to have relatively predictable effects on the actions of another person about whom
you understand nothing. Pretty much any other way one might try to influence .
another’s actions, one has to have some idea who they think they are, who they
think you are, what they might want out of the situation, and a host of similar
considerations. Hit them over the head hard enough, and none of this much matters.
