Accordingly, it is believed that the principal characteristics of the English Constitution are inapplicable in countries where the materials for a monarchy or an aristocracy do not exist. That Constitution is conceived to be the best imaginable use of the political elements which the great majority of States in modern Europe inherited from the medieval period. It is believed that out of these materials nothing better can be made than the English Constitution; but it is also believed that the essential parts of the English Constitution cannot be made except from these materials. Now these elements are the accidents of a period and a region; they belong only to one or two centuries in human history, and to a few countries. The United States could not have become monarchical, even if the Constitutional Convention had decreed it, even if the component States had ratified it. The mystic reverence, the religious allegiance, which are essential to a true monarchy, are imaginative sentiments that no legislature can manufacture in any people. These semi-filial feelings in Government are inherited just as the true filial feelings in common life.
