This dissertation is a critique of synthetic ethical naturalism (SEN). SEN is a view in metaethics that comprises three key theses: first, there are moral properties and facts that are independent of the beliefs and attitudes of moral appraisers (moral realism); second, moral properties and facts are identical to (or constituted only by) natural properties and facts (ethical naturalism); and third, sentences used to assert identity or constitution relations between moral and natural properties are expressions of synthetic, a posteriori necessities. (...) The last of these theses, which distinguishes SEN from other forms of ethical naturalism, is supported by a fourth: the semantic contents of the central moral predicates such as 'morally right' and 'morally good' are fixed in part by features external to the minds of speakers (moral semantic externalism). Chapter 1 introduces SEN and discusses the most common motivations for accepting it. The next three chapters discuss the influential "Moral Twin Earth" argument against moral semantic externalism. In Chapter 2, I defend this argument from the charge that the thought experiment upon which it depends is defective. In Chapters 3 and 4, I consider two attempts to amend SEN so as to render it immune to the Moral Twin Earth argument. I show that each of these proposed amendments amounts to an abandonment of SEN. Chapter Five explores Richard Boyd's proposal that moral goodness is a "homeostatic property cluster." If true, Boyd's hypothesis could be used to support several metaphysical, epistemological, and semantic claims made on behalf of SEN. I advance three arguments against this account of moral goodness. In the sixth chapter, I argue that moral facts are not needed in the best a posteriori explanations of our moral beliefs and moral sensibility. Because of this, those who accept a metaphysical naturalism ought to deny the existence of such facts or else accept skepticism about moral knowledge. In Chapter 7, I consider a counterargument on behalf of SEN to the effect that moral facts are needed in order to explain the predictive success of our best moral theories. I show that this argument fails. (shrink)

I defend Jack Goody's approach to explaining expansive social and intellectual changes by pointing to the contributions of the technologies of communication, and specifically, of the use of writing (Goody 1987, 2000). I argue that conceptually driven approaches to social or human kinds contribute the clarifications needed to alleviate and respond to his critics’ concerns surrounding the notion of a literate society (Collins 1995, Finnegan 1999, Sawyer 2002, Bloch 2003). My defense of Goody also identifies and endorses a few main (...) criteria and resources for the success of any satisfactory definition of the related notions of a literate society/literate mind.

abstract This article attempts to illustrate the continuing need to pay attention to ontological issues connected with the conduct of empirical research and subsequent policy making. Failure to do so leads to the conflation of social constructions with ideas about the thesis of an independent reality. Such category mistakes often lead to dilemmas in which culturally sensitive constructs may, on the one hand, be worthy of study because they do tell us how socially constructed categories do predict social phenomena; but, (...) on the other hand, such constructs may illustrate an unwillingness on the part of the research community to recognize the objective nature of such constructs. Some recommendations are suggested for addressing the social policy consequences of these dilemmas. (shrink)
