On the other hand, if they belong to the second category--to those who have a predominating tendency for the speculative, the abstract--less care will be bestowed upon the material interests; the influence of the priests will preponderate in the government; in fact, we perceive a complete antithesis to the condition above described. The Dahomees, of Western Africa, and the Caffres of the south, are examples of this state. Leaving those races whose progressive tendency is not sufficiently vigorous to enable them to extend their influence over great multitudes,[99] we come to those of a higher order, in whom this tendency is so vigorous that they are capable of incorporating, and bringing within their sphere of action, all those they come in contact with. They soon ingraft their own social and political system upon immense multitudes, and impose upon vast countries the dominion of that combination of facts and ideas--more or less co-ordinate--which we call a _civilization_. Among these races, again, we find the same difference, the same division, that I already pointed out in those of inferior merit--in some the speculative, in others the more materially active tendency predominates. It is, indeed, among these races only, that this difference has important consequences, and is clearly perceptible. When a tribe, by incorporating with it great multitudes, has become a people, has founded a vast dominion, we find that these two currents or tendencies have augmented in strength, according to the character of the populations which enter into the combination, and there become blended. Whatever tendency prevails among these populations, they will proportionably modify the character of the whole. It will be remarked, moreover, that at different periods of the life of a people, and in strict accordance with the mixture of blood and the fusion of different elements, the oscillation between the two tendencies becomes more violent, and it may happen that their relative proportion changes altogether; that one, at first subordinate, in time becomes predominant. The results of this mobility are important, as they influence, in a sensible manner, the character of a civilization, and its stability.[100]
