In An Essay on the Nature and Conduct of the Passions and Affections, with Illustrations on the Moral Sense, Francis Hutcheson answers the criticism that had been leveled against his first book, Inquiry into the Original of Our Ideas of Beauty and Virtue (1725). Together the two works constitute the great innovation in philosophy for which Hutcheson is most well known.

Professor Garrett has constructed a critical variorum edition of this great work. Because there are no manuscripts of the work, this could be done only by comparing all extant lifetime editions. Three such editions exist: those of 1728, 1730 (chiefly a reprint of the 1728 edition), and 1742. The Liberty Fund edition collates the first edition with Hutcheson's revision of 1742.

Francis Hutcheson (1694-1746) was educated at the University of Glasgow, where he assumed the chair of moral philosophy in 1729.
