Lists of the emotions which correspond to the instincts and fundamental impulses of man have been drawn up. In them we find mentioned fear, disgust, wonder, anger, elation, tender feeling, and so forth; phenomena which, by earlier writers, were classified as "passions," and to which we may conveniently give the name "feeling." We constantly speak of our emotions as our "feelings," and we contrast the man of feeling with the coldly intellectual mind in which emotion is at a minimum. But it is not alone to such specific emotions as those above-mentioned that we apply the term feeling. Thoughts are agreeable or disagreeable, pleasurable or painful. So are emotions. The agreeableness or disagreeableness, pleasantness or painfulness, which are the accompaniments of thoughts and emotions, have been called by modern psychologists their feeling-tone. It is not out of harmony with common usage to give them the name of feelings. In so doing we contrast them with knowledge and assimilate them to emotion. Whether every sensation and every thought gives rise to an emotion of some sort is matter for dispute, as is also the question whether every sensation, thought and emotion is tinged with some degree of pleasurable or painful feeling. In the absence of conclusive evidence, it is open to us to assume that some feeling is always present where there is mental activity of any kind. The feeling may be so faint and evanescent as to escape detection, but this does not prove that it is absent. 50. FEELING AND ACTION.--Emotions and feelings of pleasure and pain are the normal accompaniments of the exercise of the instincts and impulses of creatures that desire and will. Within limits, we appear to be able to take them as an index of the strength of the desire and the vigor of the effort at attainment. An act of cruelty is perpetrated. I see it, and it leaves me, perhaps, cold and unmoved. In such case, it is hardly expected of me that I should take energetic measures to have the evil-doer punished. The man whose face flushes, whose brows descend, whose teeth come together, whose fists clench, whose heart beats thickly, at the recognition of an insult, is, as a rule, the man from whom we look for vigorous efforts at retaliation. The apathetic creature who _feels_ no resentment is usually expected to swallow the indignity. The child who jumps for joy at the sight of a new doll is supposed to desire it eagerly, and to be ready to make efforts to obtain it.
