I am using this debate on abortion in my intro to philosophy class, in the section on ethics. The debate is between Prof. David Boonin (Affirmative), of U. Colorado-Boulder, and Prof. Peter Kreeft (Negative), of Boston College. If you know which of these men I greatly admire, you know who I'm agreeing with in this debate.
Check out the debate in either video or audio, held at Yale University. Note that this debate is over 90 minutes long--not for someone looking to kill a few minutes on the internet!
Just for kicks, I was going to post my five-page outline of the debate that I prepared for my students, but I don't see how I can do that on blogger. If you want a copy, let me know in the comments.
