"Does anyone suppose that Our Lord's hearers understood to mean that if a homicidal maniac, attempting to murder a third party, tried to knock me out of the way, I must stand aside and let him get his victim? I at any rate think it impossible they could have so understood Him. I think it equally impossible that they supposed Him to mean that the best way of bringing up a child was to let it hit its parents whenever it was in a temper, or, when it had grabbed at the jam, to give it the honey also. I think the meaning of the words was perfectly clear -- 'Insofar as you are simply an angry man who has been hurt, mortify your anger and do not hit back.'"
