The currency of the notion that earnest sincerity about one's opinions and ideals of conduct is inseparably connected with intolerance, is indirectly due to the predominance of legal or juristic analogies in social discussion. For one thing, the lawyer has to deal mainly with acts, and to deal with them by way of repression. His attention is primarily fixed on the deed, and only secondarily on the mind of the doer. And so a habit of thought is created, which treats opinion as something equally in the sphere of coercion with actions. At the same time it favours coercive ways of affecting opinion. Then, what is still more important, the jurist's conception of society has its root in the relation between sovereign and subject, between lawmaker and those whom law restrains. Exertion of power on one hand, and compliance on the other--this is his type of the conditions of the social union. The fertility and advance of discussion on social issues depends on the substitution of the evolutional for the legal conception. The lawyer's type of proposition is absolute. It is also, for various reasons which need not be given here, inspired by involuntary reference to the lower, rather than to the more highly developed, social states. In the lower states law, penalties, coercion, compulsion, the strong hand, a sternly repressive public opinion, were the conditions on which the community was united and held together. But the line of thought which these analogies suggest, becomes less and less generally appropriate in social discussion, in proportion as the community becomes more complex, more various in resource, more special in its organisation, in a word, more elaborately civilised. The evolutionist's idea of society concedes to law its historic place and its actual part. But then this idea leads directly to a way of looking at society, which makes the replacement of law by liberty a condition of reaching the higher stages of social development.
