 Though he stated that Blacks and Native Americans had not been the subjects of natural history, there was a large body of literature by leading naturalists of his day—e.g., Swedish biologist Carl Linnaeus ([1758] 1808), Oliver Goldsmith ([1774] 1823), and “Georges” Cuvier ([1817] 1831)—to which Jefferson had access and which he doubtless assimilated. That literature viewed Blacks and Native Americans as inferior to white Europeans, and the overall tendency was to associate darker skin with increased  inferiority.[36]  Prominent philosophers like David Hume (1755 [1987]: 208n10), Adam Smith (1759 [1982]: 208), and C.F. de Volney in (1802 [2010]: 68) also asserted the inferiority of Blacks and Native Americans.
