All recorded history shows that society developing under the conditions that have obtained up {245} to the present time—developing, that is to say, spontaneously under the random influences of an uncontrolled environment of the individual—does not permit to the average man that balanced instinctive expression which is indispensable for the formation of a rich, vigorous, and functionally active personality. It has been one of my chief efforts in this book to show that the social instinct, while in itself the very foundation of society, takes, when its action is undirected and uncontrolled, a principal part in restricting the completeness and efficacy of the social impulse. This instinct is doubly responsible for the defects which have always inhered in society through the personal impoverishment of its individual constituents. In the first place, it is the great agent by which the egoistic instincts are driven into dwarfed, distorted, and symbolic modes of expression without any regard for the objective social necessity of such oppressive regulation. In the second place, it is an instinct which, while it embodies one of the deepest and potentially most invigorating passions of the soul, tends automatically to fall out of vigorous and constant activity with the expansion of societies. It is the common character of large societies to suffer heavily from the restrictive effect on personality of the social instinct, and at the same time to suffer in the highest degree from the debilitation of the common social impulse. Only in the smallest groups, such as perhaps was early republican Rome, can the common impulse inform and invigorate the whole society. As the group expands and ceases to feel the constant pressure of an environment it no longer has to fear, the common impulse
