Ron Paul eloquently defends his position on the life issues.
Two interesting points here.
1. One of the interviewers aggressively attacks Ron Paul with the false dilemma of "Who are you going to put in jail, the woman seeking an abortion or her doctor!" Ron Paul answers with humility and a strong dose of reality. He is a passionate defender of life. This line of questioning reveals just how impoverished the thinking is on the pro-abortion advocacy side of things.
2. He says that the only way that embryonic research might be morally acceptable is when you have an ectopic pregnancy that threatens the life of the mother. Invoking the natural law principle of double effect, the action that seeks to save the mother's life results (in an unwanted fashion) with the death of the child. In this limited scope, Ron Paul suggests that it might be morally acceptable for that embryo to be reserved for research purposes.
This exchange shows how deeply informed Ron Paul is with natural law arguments on the life issue. But more so, how deeply he holds them.
