Robert P. George, professor of jurisprudence at Princeton University, is considered by some to be the “most influential conservative Christian thinker” in America. In recent years he has advanced sophisticated arguments against abortion, embryonic stem-cell research and gay marriage. The key to Robert George’s appeal is his unique brand of Natural Law ethics. He doesn’t appeal to faith, scripture or Church doctrine to advance his arguments. He invokes “no authority beyond the authority of reason itself.” For this episode the doubtcasters examine George’s complicated (and frankly bizarre) argument against gay marriage.
