Two philosophers in search of a contradiction: a response to Singer and Kuhse

Peter Singer and Helga Kuhse reject my claim that because their views on the mortality of infanticide are metaphysically incommensurate with those of Paul Ramsey they cannot refute his position. According to them, I have failed to see that Ramsey contradicts himself. Once this is seen, no further refutation is needed. I argue that there is no contradiction and offer further thoughts on the metaphysically incommensurate.
