We may grant then that sense of the object giving pain, sense of comparative power, hostility, and pains of various kinds, are usual elements in anger; yet it is evident that anger is explained by no one or all of them. It is not a mere aggregation and mixture of states, it is essentially a compound which has in some unexplained way a peculiar quality which is not in any of its constituent elements. When I am angry, there occurs a phenomenon which, while based on and inclusive of these factors, is yet peculiar in itself. The flush of anger, the wave of emotion, the tempest of passion, bases itself on and includes cognition, hostility, and pain; but it is more—it is a deep psychic disturbance of a peculiar and undefinable kind which we recognise when we have it, but which we cannot analyse. We express the nature of anger metaphorically, indeed, when we speak of an angry man being “hot,” “boiling with rage,” etc., as opposed to being chilled and frozen stiff by fear. The being angry is obviously a kind of being pained at pain quite opposite to that of fear. It is also true that I may see threatening injury, I may be pained, I may combat, but not be angry. There are other and higher motives which may bring about the violent will offensive activity so often required in the struggle of life; but we may take it that anger is the most primitive, and throughout the whole range of psychism the most common offensive motive, and so of the utmost importance as a life factor. Which shall we regard as the more primitive, anger or fear? Were animals at first universally timid, and subsequently acquired anger as an advantageous variation, or was anger the first, and fear the complementary and later evolution, or may we suppose that they developed in strict correlation? The earliest manifestations of emotion with some animals, and with some human infants, seem to be anger. Everything perceived to be painful irritates and makes them mad, and they are quite fearless in the presence of overwhelming danger. These but slowly learn to fear; by hard experience they learn the hurtfulness and inutility of combatting in many cases, and occasions which would once make them mad now cause them to fear. On the other hand, we observe many of the very young who seem to be universally fearful, and but slowly acquire “spunk” and spirit. Mental embryology thus, at least with our present very imperfect knowledge, is quite indecisive on the question. If fear and anger were wholly determined by relation of predacious and prey, then we might suppose correlated simultaneous origin; but we know that obstacles and injuries, not from competitors, but from elements, forces, and objects of nature, were the first environment and the first field for struggle. Organism began as a weak thing planted amongst manifold opposing forces, where fear was quite the most salutary emotion and anger useless. If, as we must deem probable, mental function in general
