In support of the foregoing doctrine, many particulars still more extraordinary might have been quoted from Greek and Roman writers: but truth has no occasion for artifice; and I would not take advan-<70>tage of celebrated names to vouch facts that appear incredible or doubtful. The Greeks and Romans made an illustrious figure in poetry, rhetoric, and all the fine arts; but they were little better than novices in natural history. More than half of the globe was to them the Terra Australis incognita; and imagination operates without controul, when it is not checked by knowledge: the ignorant at the same time are delighted with wonders; and the most wonderful story is always the most welcome. This may serve as an apology for ancient writers, even when they relate and believe facts to us incredible. Men at that period were ignorant in a great measure of nature, and of the limits of her operations. One concession will chearfully be made to me, that the writers mentioned, who report things at second-hand, are much more excusable than the earliest of our modern travellers, who pretend to vouch endless wonders from their own knowledge. Natural history, that of man especially, is of late years much ripened: no improbable tale is suffered to pass without a strict examination; and I have been careful to adopt no facts, but what<71> are vouched by late travellers and writers of credit. Were it true, what Diodorus Siculus reports, on the authority of Agatharchides of Cnidus, concerning the Ichthyophages on the east coast of Afric, it would be a more pregnant proof of a distinct race of men, than any I have discovered. They are described to be so stupid, that even when their wives and children are killed in their sight, they stand insensible, and give no signs either of anger or of compassion. This I cannot believe upon so slight testimony; especially as the Greeks and Romans were at that time extremely credulous, being less acquainted with neighbouring nations, than we are with the Antipodes. Varro, in his treatise De re rustica, reports it as an undoubted truth, that in Lusitania mares were impregnated by the west wind; and both Pliny and Columella are equally positive.18 The Balearic islands, Majorca, Minorca, Yvica, are at no great distance from Sicily; and yet Diodorus the Sicilian reports of the inhabitants, that at the solemnization of marriage all the male friends, and even the household servants, enjoyed the bride before the bridegroom was admit-<72>ted. Credat Judaeus appella. It would not be much more difficult to make me believe what is said by Pliny of the Blemmyans, that they had no head, and that the mouth and eyes were in the breast; or of the Arimaspi, who had but one eye, placed in the middle of the forehead; or of the Astomi, who, having no mouth, could neither eat nor drink, but lived upon smelling; or of a thousand other absurdities which Pliny relates, with a grave face, in the 6th book of his natural history, cap. 30. and in the 7th book, cap. 2.
Thus, upon an extensive survey of the inhabited parts of our globe, many nations are found differing so widely from each other, not only in complexion, features, shape, and other external circumstances, but in temper and disposition, particularly in two capital articles, courage, and behaviour to strangers, that even the certainty of different races could not make one expect more striking varieties. Doth M. Buffon think it sufficient to say dryly, that such varieties may possibly be the effect of climate, or of other accidental causes? The presumption is, that the varieties subsisting at present have always sub-<73>sisted; which ought to be held as true, till positive evidence be brought of the contrary: instead of which we are put off with mere suppositions and possibilities.
But not to rest entirely upon presumptive evidence, to me it appears clear from the very frame of the human body, that there must be different races of men fitted for different climates. Few animals are more affected than men generally are, not only with change of seasons in the same climate, but with change of weather in the same season. Can such a being be fitted for all climates equally? Impossible. A man must at least be hardened by nature against the slighter changes of seasons or weather: he ought to be altogether insensible of such changes. Yet from Sir John Pringle’s observations on the diseases of the army, to go no further, it appears, that even military men, who ought of all to be the hardiest, are greatly affected by them. Horses and horned cattle sleep on the bare ground, wet or dry, without harm, and yet are not made for every climate: can a man be made for every climate, who is so much more delicate, that<74> he cannot sleep on wet ground without hazard of some mortal disease?
But the argument I chiefly rely on is, That were all men of one species, there never could have existed, without a miracle, different kinds, such as exist at present. Giving allowance for every supposable variation of climate or of other natural causes, what can follow, as observed about the dog-kind, but endless varieties among individuals, as among tulips in a garden, so as that no individual shall resemble another? Instead of which, we find men of different kinds, the individuals of each kind remarkably uniform, and differing no less remarkably from the individuals of every other kind. Uniformity without variation is the offspring of nature, never of chance.
