"[I]n 1973 Roe v. Wade shattered the issue of abortion into sharp fragments. We are still dealing with the medical, social, and political fallout of the Supreme Court’s willingness to go far beyond the traditional boundaries of medical ethics and practice. The tenets of Hippocratic medicine have served us well for more than 2000 years, but our 25-year experiment with unrestricted abortion has caused the practice of medicine to become increasingly inconsistent, and the tension between valuable ethical traditions and currently legal medical practice is untenable."
