 There is also a sentiment commonly expressed in the secondary literature (e.g., Risjord 2002: 50–1, and Holowchak 2012, 243–48) that Jefferson had a personal, or political, interest in defending Native Americans that he did not have for Blacks. Buffon—perhaps the greatest naturalist of his day—argued that since the continent of North America was colder and wetter than that of  Europe,[39]  its biota, Native Americans included, were inferior ([NV]: 48). Consequently, “the savage” was feeble, glabrous, passionless, and compared to Europeans, was sexually less potent, less sensitive, and more timid, among other things ([NV]: 58). Abbé Raynal said more. What was true of Native Americans would eventually prove true of any Europeans transplanted in America ([NV]: 64). Jefferson put considerable effort into refuting Buffon and Raynal ([NV]: 60–64), which he did, as most scholars concede (e.g., Peden 1954: xxiii), with remarkable success, though his aim was further, open discussion more than it was refutation ([NV]: 54).
