WALTER BLOCK I listened to a podcast of Block's lecture on Abortion from Mises. In a sentence: "abortion" is killing and the libertarian should promote the eviction (where and when technologically possible) of the fetus. Also, Block actually changed my position on Terri Schiavo in one argument. I think it's an excellent approach. He also outlines three types of birth control and why the libertarian should question the use of at least one method. If you have a moment, take a listen.
