Wind stirs water by penetrating it. Thus the superior man, when obliged to judge the mistakes of men, tries to penetrate their minds with understanding, in order to gain a sympathetic appreciation of the circumstances. In ancient China, the entire administration of justice was guided by this principle. A deep understanding that knows how to pardon was considered the highest form of justice. This system was not without success, for its aim was to make so strong a moral impression that there was no reason to fear abuse of such mildness. For it sprang not from weakness but from a superior clarity.
