And this explains what is the true meaning of, and solid foundation for, that reverence for antiquity which is so strongly implanted in human nature, and is never forgotten for any considerable time without inducing the most dreadful disasters upon society. It means that those institutions which have descended to us in actual practice from our ancestors, come sanctioned by the _experience_ of ages; and that they could not have stood so long a test unless they had been recommended, in some degree at least, by their utility. It is not that our ancestors were wiser than we are; they were certainly less informed, and probably were, on that account, in the general case, less judicious. But time has swept away their follies, which were doubtless great enough, as it has done the worthless ephemeral literature with which they, as we, were overwhelmed; and nothing has stood the test of ages, and come down to us through a series of generations, of their ideas or institutions, but what had some utility in human feelings and necessities, and was on the whole expedient at the time when it arose. Its utility may have ceased by the change of manners or of the circumstances of society--that may be a good reason for cautiously modifying or altering it--but rely upon it, it was once useful, if it has existed long; and the presumption of present and continuing utility requires to be strongly outweighed by forcible considerations before it is abandoned. Lord Bacon has told us, in words which can never become trite, so profound is their wisdom, that our changes, to be beneficial, should resemble those of time, which, though the greatest of all innovators, works out its alterations so gradually that they are never perceived. Guizot makes, in the same spirit, the following fine observation on the slow march of Supreme wisdom in the government of the world:--
