The writings of Francis Hutcheson played a central role in the development of British moral philosophy in the eighteenth century. "His Illustrations on the Moral Sense" is significant not only historically but also for its exploration of problems of concern in contemporary ethics. Yet except for brief selections it has not appeared in print since the eighteenth century. This edition of "Illustrations on the Moral Sense" again makes available Hutcheson's contributions to normative ethics and metaethics, thus making possible a more accurate evaluation of his significance in the history of ethics.
