Although David Hume is no match for Immanuel Kant in terms of opaque writing, his overall philosophy is not without interpretive difficulties. Earlier this century, many philosophers read Hume as the precursor to logical positivism. Of course, the concluding words of his Enquiry Concerning Human Understanding added fuel to these flames; but with the downfall of positivism, this reading of Hume has virtually disappeared. Today, interpretations of Hume fall into two main camps: the naturalistic camp and the sceptical camp. Roughly (...) speaking, naturalistic interpreters of Hume see him as attempting to employ the methods of the natural sciences in studying human subjects while sceptical interpreters read Hume as denying that we have any knowledge. In this article I want to shed some light on this controversy in an indirect way: namely, by trying to classify Hume’s epistemology as internalist or externalist. Although this internalism/externalism debate has erupted only recently in epistemology, it should be constructive in carving up the logical space of certain epistemological positions. With this background in place, we can not only see how to categorize Hume, but also discern some of the ramifications for Hume’s epistemology when he affirms theses that place him in these categories. To anticipate a bit, I will argue that the internalist aspects of Hume’s epistemology lend great credence to the sceptical interpretation. (shrink)
