This fact has its bad side as well as its good in the feeling life, for it means that good emotions as well as bad will fade out if we fail to allow them expression. We are all perfectly familiar with the fact in our own experience that an interest which does not find means of expression soon passes away. Sympathy unexpressed ere long passes over into indifference. Even love cannot live without expression. Religious emotion which does not go out in deeds of service cannot persist. The natural end and aim of our emotions is to serve as motives to activity; and missing this opportunity, they have not only failed in their office, but will themselves die of inaction.
Relief through Expression.—Emotional states not only have their rise in organic reactions, but they also tend to result in acts. When we are angry, or in love, or in fear, we have the impulse to do something about it. And, while it is true that emotion may be inhibited by suppressing the physical expressions on which it is founded, so may a state of emotional tension be relieved by some forms of expression. None have failed to experience the relief which comes to the overcharged nervous system from a good cry. There is no sorrow so bitter as a dry sorrow, when one cannot weep. A state of anger or annoyance is relieved by an explosion of some kind, whether in a blow or its equivalent in speech. We often feel better when we have told a man "what we think of him."
At first glance this all seems opposed to what we have been laying down as the explanation of emotion. Yet it is not so if we look well into the case. We have already seen that emotion occurs when there is a blocking of the usual pathways of discharge for the nerve currents, which must then seek new outlets, and thus result in the setting up of new motor responses. In the case of grief, for example, there is a disturbance in the whole organism; the heart beat is deranged, the blood pressure diminished, and the nerve tone lowered. What is needed is for the currents which are finding an outlet in directions resulting in these particular responses to find a pathway of discharge which will not produce such deep-seated results. This may be found in crying. The energy thus expended is diverted from producing internal disturbances. Likewise, the explosion in anger may serve to restore the equilibrium of disturbed nerve currents.
Relief Does Not Follow if Image is Held Before the Mind.—All this is true, however, only when the expression does not serve to keep the idea before the mind which was originally responsible for the emotion. A person may work himself into a passion of anger by beginning to talk about an insult and, as he grows increasingly violent, bringing the situation more and more sharply into his consciousness. The effect of terrifying images is easily to be observed in the case of one's starting to run when he is afraid after night. There is probably no doubt that the running would relieve his fear providing he could do it and not picture the threatening something as pursuing him. But, with his imagination conjuring up dire images of frightful catastrophes at every step, all control is lost and fresh waves of terror surge over the shrinking soul.
Growing Tendency toward Emotional Control.—Among civilized peoples there is a constantly growing tendency toward emotional control. Primitive races express grief, joy, fear, or anger much more freely than do civilized races. This does not mean that primitive man feels more deeply than civilized man; for, as we have already seen, the crying, laughing, or blustering is but a small part of the whole physical expression, and one's entire organism may be stirred to its depths without any of these outward manifestations. Man has found it advisable as he has advanced in civilization not to reveal all he feels to those around him. The face, which is the most expressive part of the body, has come to be under such perfect control that it is hard to read through it the emotional state, although the face of civilized man is capable of expressing far more than is that of the savage. The same difference is observable between the child and the adult. The child reveals each passing shade of emotion through his expression, while the adult may feel much that he does not show.
3. CULTIVATION OF THE EMOTIONS
There is no other mental factor which has more to do with the enjoyment we get out of life than our feelings and emotions.
The Emotions and Enjoyment.—Few of us would care to live at all, if all feeling were eliminated from human experience. True, feeling often makes us suffer; but in so far as life's joys triumph over its woes, do our feelings minister to our enjoyment. Without sympathy, love, and appreciation, life would be barren indeed. Moreover, it is only through our own emotional experience that we are able to interpret the feeling side of the lives about us. Failing in this, we miss one of the most significant phases of social experience, and are left with our own sympathies undeveloped and our life by so much impoverished.
The interpretation of the subtler emotions of those about us is in no small degree an art. The human face and form present a constantly changing panorama of the soul's feeling states to those who can read their signs. The ability to read the finer feelings, which reveal themselves in expression too delicate to be read by the eye of the gross or unsympathetic observer, lies at the basis of all fine interpretation of personality. Feelings are often too deep for outward expression, and we are slow to reveal our deepest selves to those who cannot appreciate and understand them.
How Emotions Develop.—Emotions are to be cultivated as the intellect or the muscles are to be cultivated; namely, through proper exercise. Our thought is to dwell on those things to which proper emotions attach, and to shun lines which would suggest emotions of an undesirable type. Emotions which are to be developed must, as has already been said, find expression; we must act in response to their leadings, else they become but idle vaporings. If love prompts us to say a kind word to a suffering fellow mortal, the word must be spoken or the feeling itself fades away. On the other hand, the emotions which we wish to suppress are to be refused expression. The unkind and cutting word is to be left unsaid when we are angry, and the fear of things which are harmless left unexpressed and thereby doomed to die.
