nation are, the more extensively the theory gains ground--that, "all branches of the human family are endowed with intellectual capacities of the same nature, which, though in different stages of development, are all equally susceptible of improvement." This is not, perhaps, the precise language, but certainly the meaning. Thus, the Huron, by proper culture, might become the equal of the Englishman and Frenchman. Why, then, I would ask, did he never, in the course of centuries, invent the art of printing or apply the power of steam; why, among the warriors of his tribe, has there never arisen a Cæsar or a Charlemagne, among his bards and medicine-men, a Homer or a Hippocrates? These questions are generally met by advancing the influence of climate, local circumstances, etc. An island, it is said, can never be the theatre of great social and political developments in the same measure as a continent; the natives of a southern clime will not display the energy of those of the north; seacoasts and large navigable rivers will promote a civilization which could never have flourished in an inland region;--and a great deal more to the same purpose. But all these ingenious and plausible hypotheses are contradicted by facts. The same soil and the same climate have been visited, alternately, by barbarism and civilization. The degraded fellah is charred by the same sun which once burnt the powerful priest of Memphis; the learned professor of Berlin lectures under the same inclement sky that witnessed the miseries of the savage Finn.
