Hume's Scepticism and the Science of Human Nature (review)

Any new book on David Hume enters an already overcrowded field. There is no shortage of commentary on Hume's philosophy to be found in a broad range of journals such as Hume Studies, and in recent years a steady stream of monographs and collections have appeared. In addition to this rapidly expanding body of literature, rigorous textual scholarship is being brought to bear on Hume's philosophical writings in the Clarendon edition of Hume's works; significant eighteenth-century editions of Hume are more widely available thanks to facsimile reprints; and a new edition of Hume's correspondence is in preparation. Moreover, this activity has not taken place in a vacuum, insofar as the study of the Scottish Enlightenment and of key figures like Francis Hutcheson, Adam Smith, and Thomas Reid has itself been something of an academic growth industry. Consequently, the interpretation of Hume now requires considerable intellectual expertise, a familiarity with an increasingly technical secondary literature, and a firm grasp on the divergent approaches to Hume that have emerged over the past quarter century.

In Hume's Scepticism and the Science of Human Nature, Paul Stanistreet aims both to "provide the reader with an accessible guide to the most significant recent developments in Hume scholarship" and "[defend] a general interpretation of Hume's philosophy" (viii) that is largely based on a close reading of Book I of Hume's A Treatise of Human Nature. Although Stanistreet's introductory statement of his intentions may seem innocuous to the student readership his book is least partly intended for, the apparent innocence of his opening remarks masks a serious issue, namely the validity of grounding a reading of Hume primarily on the first book of the Treatise. A number of leading Hume scholars would argue, pace Stanistreet, that one cannot offer such an interpretation without reference to the two Enquiries and other texts by Hume. Furthermore, Hume himself can be read as opposing Stanistreet's approach. In the face of hostile critics like James Beattie and Thomas Reid, who focussed their attacks on the Treatise, Hume chose to exclude his first publication from the Humean canon and thereby deflect some of the ill-tempered criticism he had been forced to endure in his later years. Thus, in the "Advertisement" prefacing the 1777 edition of the Essays and Treatises on Several Subjects, he explicitly disavowed the Treatise and announced that his philosophical principles were to be found exclusively in the works included in the Essays and Treatises. For the long line of commentators fixated on the Treatise, the "Advertisement" poses questions of interpretation that cannot be ignored, and, for the benefit of his readers, Stanistreet therefore should have not only acknowledged that such questions exist, but also provided some justification for the approach to Hume he adopts.

According to Stanistreet, the key to understanding Hume's philosophy is to see how he reconciles his positive programme of constructing a "science of man" with the apparently sceptical thrust of the major arguments advanced in Book I of the Treatise. To show how this reconciliation is achieved, Stanistreet first elucidates Hume's conception of the science of human nature and then proceeds to a detailed consideration of Hume's version of the theory of ideas, his treatment of causation and probable reasoning, and his analysis of our belief in objects external to and independent of ourselves. What emerges from Stanistreet's patient exposition of Hume's position is that Hume was no Pyrrhonian, but rather an advocate for a form of mitigated scepticism that was of a piece with his science of man. For anyone with even a passing familiarity with the Hume literature, this will hardly be a startling conclusion. Nor is it news that Hume was supposedly engaged in establishing a genuinely Newtonian science of the mind, as Stanistreet argues at length in Chapter 1...
