This needful co-operation and this requisite likeness I believe to have been produced by one of the strongest yokes (as we should think if it were to be reimposed now) and the most terrible tyrannies ever known among men--the authority of 'customary law.', In its earlier stage this is no pleasant power--no 'rosewater' authority, as Carlyle would have called it--but a stern, incessant, implacable rule. And the rule is often of most childish origin, beginning in a casual superstition or local accident. 'These people,' says Captain Palmer of the Fiji,' are very conservative. A chief was one day going over a mountain-path followed by a long string of his people, when he happened to stumble and fall; all the rest of the people immediately did the same except one man, who was set upon by the rest to know whether he considered himself better than the chief.' What can be worse than a life regulated by that sort of obedience, and that sort of imitation? This is, of course, a bad specimen, but the nature of customary law as we everywhere find it in its earliest stages is that of coarse casual comprehensive usage, beginning, we cannot tell how, deciding, we cannot tell why, but ruling everyone in almost every action with an inflexible grasp. The necessity of thus forming co-operative groups by fixed customs explains the necessity of isolation in early society. As a matter of fact all great nations have been prepared in privacy and in secret. They have been composed far away from all distraction. Greece, Borne, Judaea, were framed each by itself, and the antipathy of each to men of different race and different speech is one of their most marked peculiarities, and quite their strongest common property. And the instinct of early ages is a right guide for the needs of early ages. Intercourse with foreigners then broke down in states the fixed rules which were forming their characters, so as to be a cause of weak fibre of mind, of desultory and unsettled action; the living spectacle of an admitted unbelief destroys the binding authority of religious custom and snaps the social cord.
