Many philosophers of the last century thought all moral judgments can be expressed using a few basic concepts — what are today called ‘thin’ moral concepts such as ‘good,’ ‘bad,’ ‘right,’ and ‘wrong.’ This was the view, fi rst, of the non-naturalists whose work dominated the early part of the century, including Henry Sidgwick, G.E. Moore, W.D. Ross, and C.D. Broad. Some of them recognized only one basic concept, usually either ‘ought’ or ‘good’; others thought there were two. But they (...) all assumed that other moral concepts, including such ‘thick’ ones as the virtue-concepts ‘courageous’ and ‘kindly,’ can be reductively analyzed using one or more thin concepts and some more or less determinate..

McFetridge (in Logical necessity and other essays . London: Blackwell, 1990 ) suggests that to treat a proposition as logically necessary—to believe a proposition logically necessary, and to manifest that belief—is a matter of preparedness to deploy that proposition as a premise in reasoning from any supposition. We consider whether a suggestion in that spirit can be generalized to cover all cases of absolute necessity, both logical and non-logical, and we conclude that it can. In Sect. 2, we explain the (...) significance that such an account of manifestation of belief in absolute necessity has for the prospects of a non-realist theory of modality. In Sect. 3, we offer a sympathetic articulation of the detail that underlies the McFetridge conception of belief in logical necessity. In Sects. 4 and 5, we show that the conception so articulated will not generalize to encompass all cases of belief in absolute necessity and proceed to offer a remedy. Our proposal is based upon a distinction between two kinds of suppositional act: A-supposing and C-supposing (Sect. 6). In Sect. 7, we then explain and defend our central thesis: (roughly) that (manifestation of) belief in absolute necessity is a matter of preparedness to deploy as a premise in reasoning under any C-supposition. Finally, we indicate that there is some promise in the parallel thesis that manifestation of the treatment of a proposition as a priori is a matter of preparedness to deploy as a premise in reasoning under any A-supposition (Sect. 8).

Friends of Wright-entitlement cannot appeal to direct epistemic consequentialism (believe or accept what maximizes expected epistemic value) in order to account for the epistemic rationality of accepting Wright-entitled propositions. The tenability of direct consequentialism is undermined by the “Truth Fairy”: a powerful being who offers you great epistemic reward (in terms of true beliefs) if you accept a proposition p for which you have evidence neither for nor against. However, this chapter argues that a form of indirect epistemic consequentialism seems (...) promising as a way to deal with the Truth Fairy problem. The relevant form of indirect consequentialism accommodates evidentialism but allows for exceptions in the case of anti-sceptical hypotheses. Since these are the kind of propositions to which Wright-entitlement is supposed to apply—i.e. cornerstone propositions—indirect consequentialism is entitlement-friendly. (shrink)

In a recent article, Mark Colyvan has criticized Jerrold Katz's attempt to show that Quinean holism is self-refuting. Katz argued that a Quinean epistemology incorporating a principle of the universal revisability of beliefs would have to hold that that and other principles of the system were both revisable and unrevisable. Colyvan rejects Katz's argument for failing to take into account the logic of belief revision. But granting the terms of debate laid down by Colyvan, the universal revisability principle still commits (...) Quineans to holding that one belief is both revisable and unrevisable: the belief that some beliefs are revisable. (shrink)

Jorn Sonderholm (2005) has argued that Simon Blackburn's commitment semantics for evaluative discourse is unable to explain the validity of simple inferences involving disjunction. This is true insofar as the basic rules which Blackburn suggests are not strong enough, but it is relatively simple to augment those rules so as to meet Sonderholm's challenge, whilst respecting the spirit of commitment semantics. One way of doing this is to add a reduction rule such that if accepting p commits one to inconsistent (...) commitments, one is committed to accepting ¬p. Thus Sonderholm has not provided any reason to doubt the adequacy of commitment semantics to explain validity in evaluative discourse. (shrink)

R.M. Hare had an ambitious scheme of providing a unified account of meta-ethics and normative ethics by combining expressivism with Kantianism and utilitarianism. The project of this thesis is to defend Hare’s theory in its most ambitious form. This means not just showing how the expressivist, Kantian and utilitarian elements are consistent, or that the three are each correct, but also that they are interdependent. The only defensible form of expressivism is Kantian; the only defensible Kantian theory is both expressivist (...) and utilitarian; the only defensible utilitarianism is Kantian. The thesis is divided into four chapters. Chapter 1 aims to show how expressivism can provide a coherent account of moral judgement and discourse. The argument for expressivism draws on Hare’s thought that the main error of moral realism is to think of moral objectivity as requiring objects, moral properties which are really there in the world. It is shown, using an argument based on the Euthyphro and the Open Question Argument that realism is untenable because it makes this mistake, and this clears the path to expressivism. Chapter 2 is a full account of the issues surrounding the Frege-Geach problem (often pressed against Hare), showing how it can be solved and how exactly the expressivist’s embrace of minimalism about truth interacts with the solution to the Frege-Geach Problem. I include an explanation of how the expressivist is able to solve the most threatening version of the problem: Schroeder’s discussion of negation. Chapter 3 argues for the connection between expressivism and Kantianism. The argument (roughly following Korsgaard) is that Humean versions of expressivism run into a sceptical challenge of normative regress. Kant employed a transcendental argument to resolve this regress, deriving his Formula of Universal Law from the Categorical Imperative. This argument defended with expressivism playing a crucial role. This chapter thus explains how Hare is entitled to universalizability in a way that avoids the shmoralising objection: it is not justified merely by being derived from our moral concepts but rather from our inescapable nature as agents. Chapter 4 illuminates the other connection, between Kantianism and utilitarianism. The largest part of the chapter is spent defending Hare’s argument from universalizability to utilitarianism. Doing so shows how Hare’s utilitarianism depends on his Kantianism, and so also how it indirectly depends on his utilitarianism. I then go on to defend Hare’s distinctive two-level version of utilitarianism, especially against the objections of Bernard Williams. It is also argued that various difficulties for utilitarianism – utility monsters, interpersonal comparison, Korsgaard’s objections – can be met by a form of utilitarianism like Hare’s, which is Kantian, and thus that such a form of utilitarianism is indeed the most defensible.
