Different individuals will, of course, achieve spiritual maturity and sobriety in this respect in different degrees; and those who fail of the average remain as an undissolved residue of crude humanity in the modern industrial community and as a foil for that selective process of adaptation which makes for a heightened industrial efficiency and the fullness of life of the collectivity.

This arrested spiritual development may express itself not only in a direct participation by adults in youthful exploits of ferocity, but also indirectly in aiding and abetting disturbances of this kind on the part of younger persons.

It thereby furthers the formation of habits of ferocity which may persist in the later life of the growing generation, and so retard any movement in the direction of a more peaceable effective temperament on the part of the community.

If a person so endowed with a proclivity for exploits is in a position to guide the development of habits in the adolescent members of the community, the influence which he exerts in the direction of conservation and reversion to prowess may be very considerable.

This is the significance, for instance, of the fostering care latterly bestowed by many clergymen and other pillars of society upon "boys' brigades" and similar pseudo-military organizations.
