Introducing the Instincts

Back of Our Dispositions. What is it that makes the baby jump at a noise? What energizes a man when you tell him he is a liar? What makes a young girl blush when you look at her, or a youth begin to take pains with his necktie? What makes men go to war or build tunnels or found hospitals or make love or save for a home? What makes a woman slave for her children, or give her life for them if need be? "Instinct" you say, and rightly. Back of every one of these well-known human tendencies is a specific instinct or group of instincts. The story of the life of man and the story of the mind of man must begin with the instincts. Indeed, any intelligent approach to human life, whether it be that of the mother, the teacher, the preacher, the social worker or the neurologist, leads back inevitably to the instincts as the starting-point of understanding. But what is instinct?

We are apt to be a bit hazy on that point, as we are on any fundamental thing with which we intimately live. We reckon on these instinctive tendencies every hour of the day, but as we are not used to labeling them, it may help in the very beginning of our discussion to have a list before our eyes. Here, then, is a list of the fundamental tendencies of the human race and the emotions which drive them to fulfilment.

These are the fundamental tendencies or dispositions with which every human being is endowed as he comes into the world. Differing in degree in different individuals, they unite in varying proportions to form various kinds of dispositions, but are in greater or less degree the common property of us all.

There flows through the life of every creature a

steady stream of energy. Scientists have not been able to decide on a descriptive term for this all-important life-force. It has been variously called "libido," "vital impulse" or "élan vital," "the spirit of life," "hormé," and "creative energy." The chief business of this life-force seems to be the preservation and development of the individual and the preservation and development of the race. In the service of these two needs have grown up these habit-reactions which we call instincts. The first ten of our list belong under the heading of self-preservation and the last two under that of race-preservation. As hunger is the most urgent representative of the self-preservative group, and as reproduction and parental care make up the race-preservative group, some scientists refer all impulses to the two great instincts of nutrition and sex, using these words in the widest sense. However, it will be useful for our purpose to follow McDougall's classification and to examine individually the various tendencies of the two groups.

In Debt to Our Ancestors. An instinct is the result of the experience of the race, laid in brain and nerve-cells ready for use. It is a gift from our ancestors, an inheritance from the education of the age-long line of beings who have gone before. In the struggle for existence, it has been necessary for the members of the race to feed themselves, to run away from danger, to
