Parfit argues that naturalistic theories that seek to understand normative concepts either as simply descriptive of certain natural facts about our desires or as expressive of our desires commit us to a bleak normative nihilism whereby nothing matters. I here defend such naturalism, in particular its expressivist variety, against this charge. It is true that such views commit us to there being no reasons as Parfit understands them. But for Parfit to suppose that equivalent to there being no reasons leaves (...) him begging the question where the relative credibility of these rival understandings is just what is at issue. 1.

The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...." (3) "the third thesis is that (...) the differences between the well-Known english writers on moral philosophy from sidgwick to the present day are of little importance." (staff). (shrink)
