When we face this fact in its general significance, we confront one of the ominous aspects of the history of man. We realize how little the progress of man has been the product of intelligent guidance, how largely it has been a byproduct of accidental upheavals, even though by an apologetic interest in behalf of some privileged institution we later transmute chance into providence. We have depended upon the clash of war, the stress of revolution, the emergence of heroic individuals, the impact of migrations generated by war and famine, the incoming of barbarians, to change established institutions. Instead of constantly utilizing unused impulse to effect continuous reconstruction, we have waited till an accumulation of stresses suddenly breaks through the dikes of custom.
It is often supposed that as old persons die, so must old peoples. There are many facts in history to support the belief. Decadence and degeneration seems to be the rule as age increases. An irruption of some uncivilized horde has then provided new blood and fresh life—so much so that history has been defined as a process of rebarbarization. In truth the analogy between a person and a nation with respect to senescence and death is defective. A nation is always renewed by the death of its old constituents and the birth of those who are as young and fresh as ever were any individuals in the heyday of the nation’s glory. Not the nation but its customs get old. Its institutions petrify into rigidity; there is social arterial sclerosis. Then some people not overburdened with elaborate and stiff habits take up and carry on the moving process of life. The stock of fresh peoples is, however, approaching exhaustion. It is not safe to rely upon this expensive method of renewing civilization. We need to discover how to rejuvenate it from within. A normal perpetuation becomes a fact in the degree in which impulse is released and habit is plastic to the transforming touch of impulse. When customs are flexible and youth is educated as youth and not as premature adulthood, no nation grows old.
There always exists a goodly store of non-functioning impulses which may be drawn upon. Their manifestation and utilization is called conversion or regeneration when it comes suddenly. But they may be drawn upon continuously and moderately. Then we call it learning or educative growth. Rigid custom signifies not that there are no such impulses but that they are not organically taken advantage of. As matter of fact, the stiffer and the more encrusted the customs, the larger is the number of instinctive activities that find no regular outlet and that accordingly merely await a chance to get an irregular, uncoordinated manifestation. Routine habits never take up all the slack. They apply only where conditions remain the same or recur in uniform ways. They do not fit the unusual and novel.
Consequently rigid moral codes that attempt to lay down definite injunctions and prohibitions for every occasion in life turn out in fact loose and slack. Stretch ten commandments or any other number as far as you will by ingenious exegesis, yet acts unprovided for by them will occur. No elaboration of statute law can forestall variant cases and the need of interpretation ad hoc. Moral and legal schemes that attempt the impossible in the way of definite formulation compensate for explicit strictness in some lines by implicit looseness in others. The only truly severe code is the one which foregoes codification, throwing responsibility for judging each case upon the agents concerned, imposing upon them the burden of discovery and adaptation.
The relation which actually exists between undirected instinct and over-organized custom is illustrated in the two views that are current about savage life. The popular view looks at the savage as a wild man; as one who knows no controlling principles or rules of action, who freely follows his own impulse, whim or desire whenever it seizes him and wherever it takes him. Anthropologists are given to the opposed notion. They view savages as bondsmen to custom. They note the network of regulations that order his risings-up and his sittings-down, his goings-out and his comings-in. They conclude that in comparison with civilized man the savage is a slave, governed by many inflexible tribal habitudes in conduct and ideas.
The truth about savage life lies in a combination of these two conceptions. Where customs exist they are of one pattern and binding on personal sentiment and thought to a degree unknown in civilized life. But since they cannot possibly exist with respect to all the changing detail of daily life, whatever is left uncovered by custom is free from regulation. It is therefore left to appetite and momentary circumstance. Thus enslavement to custom and license of impulse exist side by side. Strict conformity and unrestrained wildness intensify each other. This picture of life shows us in an exaggerated form the psychology current in civilized life whenever customs harden and hold individuals enmeshed. Within civilization, the savage still exists. He is known in his degree by oscillation between loose indulgence and stiff habit.
Impulse in short brings with itself the possibility but not the assurance of a steady reorganization of habits to meet new elements in new situations. The moral problem in child and adult alike as regards impulse and instinct is to utilize them for formation of new habits, or what is the same thing, the modification of an old habit so that
