The species of affinity which the ancient Persian dialects display to the languages of the adjoining countries appears to point very distinctly to another highly important conclusion in relation to the early history of mankind, viz., that the diffusion of population over Persia and the contiguous countries must have been a comparatively recent event with reference to the earliest specimens of the Persian and Semetic dialects, &c. After the lapse of a long interval the languages even of contiguous countries lose the traces of original unity. But with regard to modern dialects it can be distinctly shown that those of intermediate districts are connecting links between those of the extremities. Thus the Savoyard connects the French and Italian dialects of the Latin, and those of the North of England are intermediate between the modern English and the Lowland Scotch; Du Ponceau has made a similar remark with regard to the North American Indian dialects spoken by kindred tribes. Septs placed in the centre continue to maintain a certain degree of intercourse with all the tribes by which they are surrounded, a consideration which will account for these results, which probably cannot, in many cases, be referred to different degrees of Genealogical affinity. One of the most striking indications of the Original Unity of the different Races of Men is derivable from the uniformity of the Moral, Mental, and Social Features they display. Though the mind in early infancy may be destitute of positive ideas, it seems to be evident, nevertheless, that our Species has been gifted with Intellectual Faculties, and with Moral Sentiments and Sympathies, which are in the strictest sense innate.(18) Of this conclusion a striking confirmation is derivable, from the extraordinary sameness which, on a close examination, will be found to prevail in the characters, sentiments, and sympathies of the various branches of the Human Species. Of this truth a few examples will now be noticed.
