 It is, however, somewhat harder to discern the actual extent to which S-naturalism has been a motivation for major philosophers in the Legal Positivist tradition. There is at least a good case to be made that Hart was sufficiently attracted to S-naturalism to consider it an advantage of Legal Positivism that it placed law in the world of earthly facts. (See Hart 1961, pp. 11–12, 83–84, 186; Raz 1998, pp. 4–5; Toh 2005, pp. 83–85.) Even so, Legal Positivism need not be, and is not always, motivated by S-naturalism, or for that matter any kind of naturalism, and not all Legal Positivists are naturalists in any interesting sense. For example, Raz does not appear to be a naturalist of any sort. (See Raz 1988, p. 6.) The broader point, of course, is that one need not be a naturalist to think that some particular phenomenon (e.g., law) depends solely on naturalistic facts.
