 At the same time, however, many of the same figures’ works comfortably assume features of the naturalistic outlook. So naturalism is far from a recent invention; as Kornblith puts it, it has “a long and distinguished heritage” (1999: 158). As the subtitle of Hume’s most famous work, for example, makes clear—“An attempt to introduce the experimental method of reasoning into moral [i.e., human] subjects”—his intention was to apply the Newtonian “experimental method” to the human mind, avoiding “hypotheses” and trying to uncover the most general underlying principles. Only then, he thought, would we be in a position to get our epistemic position into proper perspective. Further, the inspiration Hume draws from sciences beyond “the science of man” (1739, “Introduction”) to which he intends his own work to be a contribution, is not merely methodological. He compares his principles of association to gravity, for example, “ideas and impressions” being the relevant domain of “objects” on which those “forces” operate (ibid., 1.1.4 para 6). Lastly, according to Barry Stroud, Hume’s “revolution in philosophy” was his use of this empirical orientation to rein in and replace an overly rationalistic conception of cognitive agents:
