According to the most consistent terminology, this tendency to enhance feeling by voluntary co-operation with functional inhibition ought perhaps to be considered as the characteristic expression of painful emotion. It is, however, as has already been pointed out in our treatment of sensation-feeling, more in conformity with ordinary usage—and also with etymology—to apply the word expression to those active, outward manifestations by which the inhibition is relieved. There can be no inconvenience in doing so if we only keep constantly in mind the distinction between the expression which enhances and the expression which relieves. As long as these two notions are confounded, a consistent explanation of emotional states is quite impossible. The contradictions in Professor James’ brilliant chapter on the emotions furnish us with a ready proof of this impossibility. If he had based his theory upon a close discrimination of either class of expression, as they can be distinguished in simple sensational feeling, he would probably not have contended that sorrow is increased by sobbing,[71] while admitting in another passage that “dry and shrunken sorrow” is more painful than any “crying fit.”[72] It is, however, impossible to deny that sighing, sobbing, twisting the hands, and other active manifestations are often effectively used, by actors, for example, as means for working up despair or sorrows.[73] But it seems to us indubitable that these movements when they succeed in creating the real feeling do so by help of association. A pain-emotion which has been called into existence by such dramatic mechanism is therefore seldom quite genuine. Real sorrow, hate, or anger, as pain-feelings, are on their physiological side much more deeply seated than these surface expressions, which, properly speaking, are merely a reproduction of the usual reactions upon the primary feeling. They are therefore not to be easily stirred up by aid of mimetic action. It may perhaps be contended that these remarks apply only to the artificial creation of pain-emotion. When under the sway of veritable sorrow we undoubtedly feel as if the mental state were really intensified during its expression by the direct influence of the muscular activities, which constitute the sighing, sobbing, or crying. As far as the compound emotion is concerned, this observation is unquestionably correct. Sorrow, with all its intellectual and volitional elements, may become more distinct for consciousness the more it is actively expressed. But the pain itself, which constitutes the primary and initial state of this emotion, has by no means been increased. On the contrary, a crying fit, for instance, as even Professor James admits, may be accompanied by a kind of excitement which has a peculiar tone of pungent pleasure.[74]
