his is a clear assessment of Hume's theories of the self and personal identity, including his famous Treatise on Human Nature . Pitson provides a critical exploration of his thinking, also examining the continuing relevance of Hume's theories for contemporary philosophy and relating it to his broader reflections on human nature itself. Divided into two parts, Pitson's study follows Hume's important distinction between two aspects of personal identity: the "mental" and the "agency". The first part discusses Hume's conception of the mind as a "bundle" or "system" of perceptions and explores Hume's position on the traditional mind/body problem. In the second part Pitson examines a range of topics including Hume's treatment of character, the relationship between human and animal nature, and the nature of agency.
