In the constrained [i.e., conservative] vision, each new generation born is in effect an invasion of civilization by little barbarians, who must be civilized before it is too late. Their prospects of growing up as decent, productive people depends on the whole elaborate set of largely unarticulated practices which engender moral values, self-discipline, and consideration for others. Those individuals on whom this process does not “take”—whether because its application was insufficient in quantity or quality or because the individual was especially resistant—are the sources of antisocial behavior, of which crime is only one form.
