In a very limited sense this is true. Where codes are wanting, former judicial decisions must serve in their place. But it would be a mistake to suppose that it is a large part of the business of American lawyers to search out precedents for the guidance of the courts. Most cases, after any facts in dispute are once settled, depend on the application of the simplest processes of ordinary reasoning. No aid from the past is needed for this and none is to be had. It has been well said by an English judge[Footnote: 1 James, L. J., in 1875, Law Reports, 10 Chancery Appeal Cases, 526.] that the clearer a thing is the more difficult it is to find any express authority or any _dictum_ exactly to the point. Nor, if there be one, is it to be accepted without regard to the circumstances out of which it arose or the end to be effected by the judgment. A precedent may indeed be used slavishly, but so it may be used in the free spirit in which it was conceived. Many an argument at the bar, however, is ruined by an excessive anxiety to repeat the _ipsissima verba_ of some ancient opinion, when the soul of it is the only thing of value. And occasionally courts are chargeable with pursuing the letter of some of their former deliverances rather than the spirit which called them forth and gave them all their vitality. * * * * * CHAPTER V THE JUDICIAL POWER OF DEVELOPING UNWRITTEN LAW The English common law was and is an unwritten law. To find it one has to look in legal treatises and reports of judicial decisions. Its historical development has been not unlike that of Rome. In Rome, as in England, there were in early times written enactments or governmental declarations of standing rules on but few points. Some of these writings were of special importance, such as the twelve tables of Rome and the _Magna Charta_ of England. These were regarded as so bound up with the very life of the people as to have a place by themselves, and a superior force to anything to the contrary to which the free consent of the people was not formally given. But in general Romans and Englishmen preferred to make custom their law, and to let this law grow "not with observation," but insensibly from day to day as the needs of their social organization might be found to require. It was a wise preference, and founded on a better philosophy than they knew--than the world knew, until the theory of evolution was demonstrated by Darwin and applied to governmental science by Spencer.
