"Constitutional attorney and author of Men in Black: How the Supreme Court is Destroying America, Mark R. Levin refers to Justice Blackmuns opinion: “We need not resolve the question of when life begins. When those trained in the respective disciplines of medicine, philosophy, and theology are unable to arrive at any consensus, the judiciary, at this point in the development of man’s knowledge, is not in the position to speculate as to the answer.” Levin goes on to comment, “Blackmun gave deference to medicine, philosophy, and theology (from his own perspective) but not to the Constitution, the people, the states, or the other branches of the federal government. In truth, Blackmun did establish, at least for constitutional purposes, when life begins by recognizing abortion as a constitutionally protected right to privacy. He did precisely what he lectures should not be done.”"
