The stimulus of the same catastrophe, it thus appears, may result in two different types of responses--that of greed on the one hand or altruistic emotion on the other. One individual is spurred to increased activity by the opportunity of business profit, another by the sense of social needs. Why this is so--indeed the whole field of profiteering--would be a subject of interesting enquiry. Whether it is due to the varying degrees of socialization represented in the different individuals or whether it is not also partly due to the fact that philanthropy functions best in a sphere out of line with a man's own particular occupation, the truth remains that some display an altogether unusual type of reaction in an emergency to the actions of others; and perhaps exhibit behavior quite different from that which appears normal in a realm of conduct where associations based on habit are so strongly ingrained. The human will as we have seen is in close association with the emotions. We are now to notice the dynamogenic value of the strong emotions aroused by catastrophe. It is first of all essential to remember the role of adrenin in counteracting the effects of fatigue. Wonderful phenomena of endurance in disaster might well be anticipated for "adrenin set free in pain and in fear and in rage would put the members of the body unqualifiedly at the disposal of the nervous system." This is "living on one's will" or on "one's nerve." There are "reservoirs" of power ready to pour forth streams of energy if the occasion presents itself. Strong emotions may become an "arsenal of augmented strength." This fact William James was quick to see when he said "on any given day there are energies slumbering within us which the incitements of that day do not call forth."[78] But it was left to Cannon to unfold the physiological reasons,[79] and for Woodworth to explain how the presence of obstruction has power to call forth new energies.[80] Indeed the will[81] is just the inner driving force of the individual and an effort of will is only "the development of fresh motor power."[82] Following the lines of least resistance the will experiences no unusual exercise. Catastrophe opposes the tendency to eliminate from life everything that requires a calling forth of unusual energies. [78] James, William, _The Energies of Men_ (N. Y., 1920), p. 11.

[81] Will is indeed the supreme faculty, the whole mind in action, the internal stimulus which may call forth all the capacities and powers.
