"This very readable and accurate translation of the so-called Treatise on Human Nature strikes the right balance between literal rendition of Aquinas' Latin and naturalness of English expression, and thus will be of use both to new students of Aquinas and to those familiar with the original Latin. The commentary on the text should make the translation especially suitable for use in courses on Aquinas' philosophy of human nature and theory of knowledge."---Deborah Black, Professor of Philosophy, University of Toronto --
