Hume's Epistemological Evolution

Book excerpt: "Here is a central issue in Hume scholarship: what is the relationship between Hume's early Treatise of Human Nature and his later Enquiry Concerning Human Understanding? Is the Enquiry a mere simplified restatement of the contents of the Treatise, or do the two substantially differ? Here is another critical issue in Hume scholarship: what is the relationship between Hume's scepticism and his naturalism? How can we reconcile Hume's extreme brand of scepticism with his positive ambitions of providing an account of human nature? Hume's Epistemological Evolution argues that these two issues are intimately related. In particular, this book argues that Hume's Enquiry indeed differs from the Treatise, precisely because he changes his response to scepticism between the two works. Because the Treatise has as its primary focus the psychological naturalistic project, its treatment of epistemological issues arises unsystematically from the psychological investigation. Consequently, Hume finds himself forced into an unsatisfactory response to scepticism founded on the Title Principle (THN 1.4.7.11). However, this response is deeply problematic, as Hume himself seems to recognise. In contrast to the Treatise, the Enquiry emphasises the epistemological aspects of Hume's project, and offers a radically different and more sophisticated epistemology. This framework addresses the weaknesses of the earlier one, and also constitutes a 'compleat answer' to two of his most prominent critics, Thomas Reid and James Beattie. Hume's epistemology thus undergoes an evolution between these two works"--
