Ethics and Humanity pays to tribute to Jonathan Glover, a pioneering figure whose thought and personal influence have had a significant impact on applied philosophy. In topics that include genetic engineering, abortion, euthanasia, war, and moral responsibility, Glover has made seminalcontributions. The papers collected here, written by some of the most distinguished contemporary moral philosophers, address topics to which Glover has contributed, with particular emphasis on problems of conflict discussed in his book, Humanity: A Moral History of the Twentieth Century. There arealso moving testaments to the influence Glover has had on colleagues, students, and friends. Glover himself contributes a series of fine replies, which constitute an important addition to his published work.
