Abstract

I discuss first the meaning of naturalism in philosophy and then the sense in which it has been introduced in ethics: that of American Naturalism, that of Dewey’s pragmatism, the sense of a negation of Moore’s negation of naturalism, the neo-Aristotelian, and the one of the external realists. I will argue a fundamental heterogeneity of these meanings and will add that the reasons for the apparent unity of a naturalist front in recent philosophical debates lies more in factors pertaining to the sociology of knowledge. I will suggest that there is one sense in which a naturalism claim may be defended, the sense of Aristotle and Dewey, according to which moral good is not specifically moral in its nature. I will add that programs of scientific exploration into biological bases of behaviour and co-ordination of behaviour within groups are highly promising, but are in no sense ‘naturalistic’ and are indeed compatible with ethical intuitionism, or Kantian ethics
