ABSTRACT
In a study of the psychology of aggression a severe strain is imposed on the student, for the following reason. In a total psychology, being-stolen-from is the same as stealing, and is equally aggressive. Being weak is as aggressive as the attack of the strong on the weak. Murder and suicide are fundamentally the same thing. Perhaps most difficult of all, possession is as aggressive as is greedy acquisition; indeed acquisition and possession form a psychological unit, either is incomplete without the other. This is not saying that acquiring and possessing are good or bad.
