ABSTRACT
The frantic and senseless actions of an enraged man may be attributed in part to the undirected flow of nerve-force, and in part to the effects of habit, for these actions often vaguely represent the act of striking. Whenever the emotions or sensations are even slightly felt by humans, though they may not at the time lead to any exertion, humans whole system is nevertheless disturbed through the force of habit and association. Affection indeed, in as far as it is a pleasurable sensation, excites the ordinary signs of pleasure. Many of the effects due to the excitement of the nervous system seem to be quite independent of the flow of nerve-force along the channels which have been rendered habitual by former exertions of the will. The chapter considers how far the will and consciousness have come into play in the development of the various movements of expression.
