It must be borne in mind that the races comprised under these divisions, are by no means to be considered equal among themselves. We should lay it down as a general truth, that while the entire groups differ principally in _degree_ of intellectual capacity, the races comprised in each differ among themselves rather in kind. Thus, we assert upon the testimony of history, that the white races are superior to the yellow; and these, in turn, to the black. But the Lithuanian and the Anglo-Saxon both belong to the same group of races, and yet, history shows that they differ; so do the Samoyede and the Chinese, the negro of Lower Guinea, and the Fellah. These differences, observable among nations classed under the same head, as, for instance, the difference between the Russians and Italians (both white), we express in every day's language by the word "genius." Thus, we constantly hear persons speak of the artistic, administrative, nautical genius of the Greeks, Romans, and Phenicians, respectively; or, such phrases as these, which I borrow from Mr. Gobineau: "Napoleon rightly understood the _genius_ of his nation when he reinstated the Church, and placed the supreme authority on a secure basis; Charles I. and his adviser did not, when they attempted to bend the neck of Englishmen under the yoke of absolutism." But, as the word _genius_ applied to the capacities or tendencies of a nation, in general implies either too much or too little, it has been found convenient, in this work, to substitute for it another term--_instinct_. By the use of this word, it was not intended to assimilate man to the brute, to express aught differing from intellect or the reasoning capacity; but only to designate the peculiar manner in which that intellect or reasoning capacity manifests itself; in other words, the special adaptation of a nation for the part assigned to it in the world's history; and, as this part is performed involuntarily and, for the most part, unconsciously, the term was deemed neither improper nor inappropriate. I do not, however, contend for its correctness, though I could cite the authority of high names for its use in this sense; I contend merely for its convenience, for we thereby gain an easy method of making distinctions of _kind_ in the mental endowments of races, in cases where we would hesitate to make distinctions of _degree_. In fact, it is saying of multitudes only what we say of an individual by speaking of his _talent_; with this difference, however, that by talent we understand excellency of a certain order, while instinct applies to every grade. Two persons of equal intellectual calibre may have, one a talent for mathematics, the other for literature; that is, one can exhibit his intellect to advantage only in calculation, the other only in writing. Thus, of two nations standing equally high in the intellectual scale, one shall be distinguished for the high perfection attained in the fine arts, the other for the same perfection in the
