During its first two years of publication, Philosophy & Public Affairs contributed to the public debate on abortion a set of remarkable and brilliant articles which examine the basic philosophical issues posed by this controversial subject: whether the fetus is a person, whether it has a right to life, whether a woman has a right to decide what happens in and to her body, whether there is an ethical connection between abortion and infanticide, whether there is any point after conception where it is possible to draw the line beyond which killing is impermissible. These five essays, together here for the first time in a single volume, offer radically differing points of view; they provide the best sustained discussion of these philosophical issues available anywhere. Contents: Judith Jarvis Thomson, "A Defense of Abortion"; Roger Wertheimer, "Understanding the Abortion Argument"; Michael Tooley, "Abortion and Infanticide"; John Finnis, "The Rights and Wrongs of Abortion"; and Judith Jarvis Thomson, "Rights and Deaths."
