Pain is certainly a prominent element in anger. This pain is the emotional pain, the pain at pain, whose nature and origin we have commented on in the chapter on fear. The mere representation of pain to be starts a violent pain quite distinct from the fear-pain, yet like it, pre-eminently central and subjective. Precedent, however, to both fear and anger-pain, is the simple pain which immediately arises on representation of pain, the prospect of pain being immediately and peculiarly painful in itself. This commonly continues throughout, and gives a dominant pain tone. But there immediately succeeds a rush of either fear or anger emotion, each intensely painful in opposite ways. The pain which results from the anger, which is by the anger occasioned in me, is again distinct from the pain in and of the anger. Anger is itself a state of pain. In its earliest forms, as rarely and with difficulty attained, there is still another pain connected with anger, the pain of exertion and stress. But all the pain factors, as more or less continuous, make anger, as emotion in general, a complex pain state. Thus, when angered by a man shaking his fist in my face, we trace first a purely subjective pain at prospect of pain, then a rush of aggressive emotion which embodies in it a pain of its own, then a pain which reacts from the peculiar tension of the anger state. Of course, in our stage of evolution, anger has become such an inwrought factor that it arises spontaneously, it overtakes and overcomes us, not we reaching it; and so the stress or labour pain is absent. It is never or very rarely an effort for us to get angry, but it must have been for our very remote psychical ancestors.
