It is therefore to the psychology of feeling and expression that we shall turn for the solution of the problem of the art-impulse.

CHAPTER III
THE FEELING-TONE OF SENSATION

Before attempting to prove that the impelling force in art-creation is to be explained by the psychology of feeling, we must first pay some attention to the general theory of emotional states. It would be impossible to assert anything about the æsthetic importance of such activities as have their origin in emotional conditions without first having made out the relation between feeling and movement.

In this purely psychological investigation it is advantageous to postpone all æsthetic considerations. The important thing is to get hold of the mental factors in their simplest possible form. Even the lowest feelings, therefore, the feeling-tones of mere physical sensation or the vaguest emotional states, such as comfort or discomfort, which are overlooked in all works on æsthetic proper, may be of great value in this preliminary discussion.

It is preferable to begin with the feeling-tones of definitely physical origin, because these hedonic elements have been subjected to an experimental investigation which could never be undertaken with regard to the complex emotions and sentiments. As early as 1887 Féré published some important researches on the relation between sensation and movement. By submitting persons to various external stimuli, he showed that every such stimulus calls forth a modification of the activities of the body, which modification, according to the intensity and the duration of the stimulus, takes the character either of enhancement or of arrest. In all cases when the apparatus used in the experiments indicated a shortened reaction-time and an increased development of energy, the subject of the experiment had experienced a feeling of pleasure. Every painful stimulus, on the other hand, was connected with a diminution of energy.[41]

These results have been corroborated in the main by the later researches of Lehmann. He has not, however, restricted his attention to the development of energy, but has also measured the changes in pulsation and respiration which occur under the influence of various stimuli. His conclusions are these:—

“Simple pleasurable sensations are accompanied by dilatation of the blood-vessels, and perhaps also by an increase in the amplitude of heart-contraction, together with an increase in the innervation of the voluntary muscles, at least of those connected with respiration. In sensations of pain one has to distinguish the first shock of irritation from the subsequent state. At the moment of irritation there ensues a deeper inhalation, and, if the irritation is strong, also an increase in the innervation of voluntary muscles. Then there generally follows a relaxation.”[42]

The physiological theory of pleasure and pain which can be deduced from these experiments is, however, neither new nor original. Féré has himself pointed out that his researches only serve to prove the views which have been advanced with more or less explicitness by Kant, Bain, Darwin, and Dumont.[43] All authors who have closely studied the movements of expression have also remarked that pleasurable feelings are accompanied by a tendency towards increased activity (Gratiolet, Darwin, Bain, Bouillier, Mantegazza).[44] And the popular views on pleasure and pain, as we find them expressed in literature, all agree on this point: “La joie est l’air vital de notre âme. La tristesse est un asthme compliqué d’atonie.”[45] Every one knows that movement and unchecked increased activity generally create pleasure. And, on the other hand, functional inhibition is in our experience closely connected with feelings of pain.

Although these broad facts are universally recognised, there is nevertheless no unanimity with regard to their interpretation. It may be held, on the one hand, that the perception of those objective conditions which call forth pleasure is accompanied by a tendency to movement. That, conversely, movement creates pleasure would thus be the result of an association. But it may also be contended that the functional enhancement, the stimulation itself, when present to consciousness, is perceived as pleasure, and that the feeling-tone created by movement is thus not indirect and secondary, but, on the contrary, is a typical pleasure.

We do not by any means deny the influence which associative processes exercise on all our feelings and on the activities connected with them. As has been shown by Darwin, animals as well as primitive man have earned their chief enjoyment, outside their delight of warmth and repose, by violent actions, such as hunting, war, and pairing fights.[46] And if it be objected that memories from those distant times cannot now influence our feelings, it must at least be admitted that within the life of the individual a firm foundation is laid for association between pleasure and activity.[47] Independently of all general theories, we must therefore reckon with association as a factor by which the motor element of pleasure is greatly increased. But it seems to us impossible to make the remembrance—conscious or unconscious—of earlier similar states the only ground of the activity which is connected with pleasurable feelings.
