The rapid development of connectionist models in computer science and of powerful computational tools in neuroscience has encouraged eliminativist materialist philosophers to propose specific alternatives to traditional mentalistic theories of mind. One of the problems associated with such a move is that elimination of the mental would seem to remove access to ideas like truth as the foundations of normative epistemology. Thus, a successful elimination of propositional or sentential theories of mind must not only replace them for purposes of our (...) psychology, it must also replace them for purposes of the evaluation of our theories and explanations, psychological and otherwise. This paper briefly reviews eliminativist arguments for doubting the correctness of sentential accounts of explanation, understanding, and normative evaluation. It then considers Paul Churchland's (1989) proposed alternative norms, which are framed neurocomputationally. The alternative is found wanting in several specific ways. The arguments for eliminating propositionally-based norms are then re-examined and it is suggested that the need for wholesale elimination is overstated. A clear gap in the traditional epistemological story is identified, however, and a more modest set of norms is proposed as a way of filling this gap, rather than as a way of entirely replacing the traditional framework.

Prompted by the thesis that an organism’s umwelt possesses not just a descriptive dimension, but a normative one as well, some have sought to annex semiotics with ethics. Yet the pronouncements made in this vein have consisted mainly in rehearsing accepted moral intuitions, and have failed to concretely further our knowledge of why or how a creature comes to order objects in its environment in accordance with axiological charges of value or disvalue. For want of a more explicit account, theorists (...) writing on the topic have relied almost exclusively on semiotic insights about perception originally designed as part of a sophisticated refutation of idealism. The end result, which has been a form of direct givenness, has thus been far from convincing. In an effort to bring substance to the right-headed suggestion that values are rooted in the biological and conform to species-specific requirements, we present a novel conception that strives to make explicit the elemental structure underlying umwelt normativity. Building and expanding on the seminal work of Ayn Rand in metaethics, we describe values as an intertwined lattice which takes a creature’s own embodied life as its ultimate standard; and endeavour to show how, from this, all subsequent valuations can in principle be determined.

In this thesis I provide an overview of Nietzsche's ethics with an emphasis on showing how his naturalistic approach to ethics leads him to advance an egoistic moral code. I argue that this, though radical in the light of conventional morality, is not irrational, unprincipled, or proscriptive of other-regarding moral considerations. On the contrary, it demands the highest degree of foresight and integrity. While Nietzsche's writings are meant for a select group of people, namely "higher men," whose flourishing may be (...) undercut by their unwitting acceptance of a self-destructive morality. I explain that Nietzsche places the highest degree of value on the life of these individuals, the development of their character, and their flourishing. Further, I explain that Nietzsche extols as a great virtue "bestowing" or "gift-giving," and that he takes generosity to be more frequently practiced under an ethics of egoism. (shrink)

Until recently it has been conventional to assume that ethical egoism is "ethical" is name, alone, and that no account that considers one's own interests as the standard of moral obligation could count as seriously "ethical." In recent years, however, philosophers have shown increasing respect for more sophisticated forms of ethical egoism which attempt to define self-interest in enriched terms characterizing self-interest as human flourishing in both material and psychological dimensions. But philosophers are still skeptical that any conception of self-interest (...) could underpin ethical theory. This paper considers recent arguments by Richard Joyce, who is willing to concede enriched conceptions of self-interest, but who claims that egoism cannot support appropriate counterfactual conditionals about morality, or inferential uses of ordinary moral thinking. I argue that ethical egoism can satisfy each of Joyce's desiderata for morality, provided that it is taken to involve the very notion of enriched self-interest that Joyce is elsewhere willing to consider. In showing that egoism can count as a moral theory, I show, in effect, that Joyce's arguments for error theory about morality are really arguments for error theory about agent-neutral, non-egoistic morality.
