Over at Crescat Sententia, Will Baude has been defending subjectivism about morality. Will doesn’t defend the traditional positivist view that "Murder is wrong" means (roughly) "Boo for murder!", but rather that it means "I disapprove of murder". Freespace’s Timothy Sandefur responds to Will with several moral and legal arguments. This seems to me to be a mistake. Will’s making a metaphysical and semantic claim, and the right responses will be based on metaphysics or semantics. Fortunately, there are plenty of the latter kind of argument.
Dan Drezner weighs in about the reasons for the war in Iraq and, in particular, whether a President might be justified in lying to the country in order to invade. Steven Den Beste believes that the nation wasn’t told the real reason for invading, but that the ends justify the means. Josh Marshall thinks that this is unjustifiable.
