One result of this isolation was that the South was more homogeneous than the North, and perhaps more distinctly American in its characteristics. This was to be expected, since it had one common and overmastering interest in slavery, had little foreign admixture, and was removed from the currents of commerce and the disturbing ideas of Reform. The South, so far as society was concerned, was an agricultural aristocracy, based upon a perfectly defined lowest class in the slaves, and holding all trade, commerce, and industrial and mechanical pursuits in true mediæval contempt. Its literature was monarchical, tempered by some Jeffersonian, doctrinaire notions of the rights of man, which were satisfied, however, by an insistence upon the sovereignty of the States, and by equal privileges to a certain social order in each State. Looked at, then, from the outside, the South appeared to be homogeneous, but from its own point of view, socially, it was not at all so. Social life in these jealously independent States developed almost as freely and variously as it did in the Middle Ages in the free cities of Italy. Virginia was not at all like South Carolina (except in one common interest), and Louisiana—especially in its centre, New Orleans—more cosmopolitan than any other part of the South by reason of its foreign elements, more closely always in sympathy with Paris than with New York or Boston, was widely, in its social life, separated from its sisters. Indeed, in early days, before the slavery agitation, there was, owing to the heritage of English traditions, more in common between Boston and Charleston than between New Orleans and Charleston. And later, there was a marked social difference between towns and cities near together—as, for instance, between agricultural Lexington and commercial Louisville, in Kentucky.
