The functions of body, on which life is founded, do not depend upon reason. The heart begins to beat before birth; it continues to beat until the end of life. The reason has nothing to do with the heart performing its function. Man goes to sleep at night confident that it will still be beating in the morning. The blood circulates in the veins independent of the thoughts of man. The digestive processes go on whether he sleeps or is awake. Many of his muscles never rest from birth to death. Life could not be preserved through the intellectual processes.

Human action is governed largely by instinct and emotion. These instincts and emotions are incident to every living machine and are the motor forces that impel the organism. They do not think. They act, and act at once. All the mind can do is to place some restraint on such instincts and emotions through experience, education and settled habits. If the actions are never inhibited, the machine will tear itself to pieces. If too easily inhibited, it will do no work. It is manifest that the perfect machine does not exist.

Man is moved by his instinct of flight and his emotion of fear, which are set in motion by apprehended dangers and by unaccustomed sights or sounds. Terror sometimes becomes so intense that it prevents flight and brings convulsions and death. It is idle to reason with one in terror. It is idle to reason with a mob in terror or a nation in terror. One might as well expect to calm a tempestuous sea with soft words.

The instinct of repulsion brings hatred and dislike and, combined with the instinct of pugnacity, may lead to crimes of violence. When these instincts are strong enough, the weak and superficial barriers cannot stand against them. An electrical flash showing the scaffold with the noose above it would have no force to stop an instinct and emotion fully aroused. Through seeing, feeling, hearing, tasting or smelling, some instinct is called into action. Many times several conflicting instincts are aroused. The man is like a tree bent back and forth by the storm. If the storm is hard enough, sooner or later it will break. Which way the tree falls has nothing to do with the consciousness of the tree, but has to do only with the direction of the prevailing and controlling force.

The instinct of gregariousness draws animals or men together into communities and close relations. This is one of the strongest instincts and not only preserves life but is fundamental to those human associations that are the basis of civilization. Except for this, animals would live a lonely life and probably perish from the earth. Through this instinct, man builds his villages and cities and organizes his states and nations. With the gregarious instinct and the parental instinct drawing men together, and the instincts and emotions of flight, fear and pugnacity, repelling and pushing them apart, conflict is inevitable. All that can be done is to create and cultivate as strong habits, customs and laws as possible to stand against the power of instinct and emotion in time of need, and to remove the main inciting causes so far as man has the intelligence and power to remove them. It is evident that this can never be complete. There are too many weak machines, too many defective nervous systems, too many badly organized brains. Accidents are inevitable, and some accidents are called "crimes." When the accident is international or world-wide, it means war. Those who believe that there is any power to stop all the harmful manifestations of man's instincts, either individually or en masse, do not understand the fundamental nature of man.

Many and probably all instincts work both for good and ill. Flight, pugnacity, repulsion, sex—all are life-preserving or life-destroying, as the case may be. A certain degree of excitation brings life and pleasure. A stronger or weaker may bring calamity and death. The parental instinct, with the instinct of reproduction, is fundamental to life. It is the basis of tenderness and sympathy, and is likewise the foundation of jealousy and often of hatred and pugnacity. At one time it may mean the deepest and most abiding pleasures of life, and at another it may bring death. Life cannot exist without it, and yet, that it may persist, Nature seriously overloads many machines with disastrous results. History is replete with the helplessness of reason and judgment in dealing with these emotions. Neither when they act for good nor for ill can reason and judgment have the slightest weight when these instincts and emotions are stirred to the depths.

The emotion to acquire and keep property is very strong and perhaps at the base of the deep desire for wealth. This emotion is probably of a comparatively late growth, but today it seems to have taken its place as one of the strongest that move men. This emotion, like all others, prompts man to get what he wants. It of course does not suggest the way, but is simply an urge to acquire and possess. It is modified and hedged about by customs and habits but, like all instincts, its strength is always seeking ways to accomplish results regardless of the rules laid down and thus urging their violation. With weak machines and imperfect systems, where not only are the restrictions imperfect, the habits not well defined, but where it is impossible to satisfy the instinct under the rules laid down, there can be but one result; a large number will take property wherever and however they can get it.

The instinct for acquisition is so strong that men are constantly contriving new and improved methods for getting property. Often the new methods come under restraint of the law. The enactment of the law does not give man the feeling that a thing is wrong which before was right and many continue their ways of getting property, regardless of the law. The instinct is too strong, the needs too great, and the barriers too weak.

Instincts are primal to man. He has inherited them from the animal world. Their strength and weakness depend on the make-up of the machine. Some are very strong and some abnormally weak, and there are no two machines that emphasize or repress the same instincts to the same degree. One need but look at his family and neighbors to see the various manifestations of these instincts. Some are quarrelsome and combative and will fight on the slightest provocation. Others are distinctively social; the gregarious instinct is pronounced in many people. These are always seen in company and cannot be alone. They readily adapt themselves to any sort of associations. Others are solitary. They choose to be alone. They shrink from and avoid the society of others. In some the instinct at the basis of sex association is over-strong; they like children; they are generally sympathetic and emotional, and the strength of the instinct often leads them to excesses. Others are entirely lacking in this instinct; they neither care for children nor want them; they habitually avoid association with the other sex. The difference is constituent in the elements that make up the machine.

Everyone is familiar with the varying strength and weakness of the instincts of getting and hoarding as shown by his neighbors and acquaintances. Some seem to have no ambition or thought for getting or keeping money. Some can get it but cannot keep it. Some have in them from childhood the instinct for getting the better of every trade; for hoarding what they get, and accumulating property all their lives. In this, as in all other respects, no two individuals are alike. History is filled with examples of men who had the instinctive power of getting money combined with the instinct for keeping it. Their names are familiar, all the way from Midas and Croesus down to the prominent captains of industry today. It is common for them and their adherents who criticise new schemes of social organization to remark with the greatest assurance that before wealth can be equal, brains must be equal. The truth is that brains have little to do with either the making or accumulating of money. This depends mainly, like all other activities, on the strength or weakness of the instincts involved. One's brain capacity cannot be measured by his bank account, any more than by the strength of his body or the color of his hair. His bank account simply shows his innate tendencies. There is no doubt that brain capacity as well as physical perfection adds to power, but it is the instinct that determines the tendency and strength of the activity.
