“We are likely to think of the savage as a freakish creature, all moods—at one moment a friend, at the next moment a fiend. So he might be were it not for the social drill imposed by his customs. So he is, if you destroy his customs, and expect him nevertheless to behave as an educated and reasonable being. Given, then, a primitive society in a healthy and uncontaminated condition, its members will invariably be found to be on the average more law-abiding, as judged from the stand-point of their own law, than is the case in any civilized state.

“Of course, if we have to do with a primitive society on the down-grade—and very few that have been ‘civilizaded,’ as John Stuart Mill terms it, at the hands of the white man are not on the down-grade—its disorganized and debased custom no longer serves a vital function. But a healthy society is bound, in a wholesale way, to have a healthy custom.”
