"Our lady the Common Law will note other people's fashions and take a hint from them in season, but she will have no thanks for judges or legislators who steal incongruous tags and patches and offer to bedizen her raiment with them. Assimilation of foreign elements, we have already seen, may be a very good thing. Crude and hasty borrowing of foreign details is unbecoming at best, and almost always mischievous. When you are tempted to make play with foreign ideas or terms, either for imitation or for criticism, the first thing is to be sure that you understand them."
