Pro-choice versus pro-life has been a key topic of American political debate since Roe v. Wade. Boldly and deliberately, Kischer (University of Arizona College of Medicine) and Irving (DeSales School of Theology) blended their distinctive scholarly specializations and in so doing, exposed the myths and revealed the scientific facts and philosophical basis for defining human life; the result is a sound argument and logical defense of the “Right to Life” position. Accepted worldwide as a primary life issues reference book, a copy of this book was accepted by Pope John Paul II for inclusion in the Vatican Library and was a required reference during the 1996 Doctors for Life conference in Johannesburg, South Africa.
