The abortion debate rages on. Yet the two most popular positions seem to be clearly mistaken. Conservatives maintain that a human life begins at conception and that therefore abortion must be wrong because it is murder. But not all killings of humans are murders. Most notably, self defense may justify even the killing of an innocent person.Liberals, on the other hand, are just as mistaken in their argument that since a fetus does not become a person until birth, a woman (...) may do whatever she pleases in and to her own body. First, you cannot do as you please with your own body if it affects other people adversely. Second, if a fetus is not a person, that does not imply that you can do to it anything you wish. Animals, for example, are not persons, yet to kill or torture them for no reason at all is wrong. (shrink)

An emerging view of science rejects an infallible observational given and takes consensus as the starting point for confirmation. Theory and Observation are seen as mutually correcting. I argue that the same is true of ethics, such as Rawls' "reflective equilibrium." Though epistemologically similar, their truth conditions may differ. Ethics may be reducible to physics; but even if it is not, that does not imply that it has no truth conditions. The options for truth in ethics are the same as (...) those of other abstract fields such as mathematics. (shrink)
