When an individual wishes to stand in opposition to authority, he does best to find support for his position from others in his group. The mutual support provided by men for each other is the strongest bulwark we have against the excesses of authority. (Not that the group is always on the right side of the issue. Lynch mobs and groups of predatory hoodlums remind us that groups may be vicious in the influence they exert.)
