This paper is a concise survey of recent expressivist theories of discourse, focusing on the ethical case. For each topic discussed recent trends are summarised and suggestions for further reading provided. Issues covered include: the nature of the moral attitude; ‘hybrid’ views according to which moral judgements express both beliefs and attitudes; the quasi-realist programmes of Simon Blackburn and Allan Gibbard; the problem of creeping minimalism; the nature of the ‘expression’ relation; the Frege-Geach problem; the problem of wishful thinking; the (...) role of moral intuitions; expressivism in aesthetics.

To clarify and illuminate the place of probability in science Ellery Eells and James H. Fetzer have brought together some of the most distinguished philosophers ...

After offering a characterization of what unites versions of ‘expressivism’, we highlight a number of dimensions along which expressivist views should be distinguished. We then separate four theses often associated with expressivism – a positive expressivist thesis, a positive constitutivist thesis, a negative ontological thesis, and a negative semantic thesis – and describe how traditional expressivists have attempted to incorporate them. We argue that expressivism in its traditional form may be fatally flawed, but that expressivists nonetheless have the resources for (...) preserving what is essential to their view. These resources comprise a re-configuring of expressivism, the result of which is the view we call ‘neo-expressivism’. After illustrating how the neo-expressivist model works in the case of avowals and ethical claims, we explain how it avoids the problems of traditional expressivism. (shrink)

This paper addresses and rejects claims that one can demonstrate experimentally that most untutored subjects are systematically and incurably irrational in their probability judgements and in some deductive reasoning tasks. From within a strongly subjectivist theory of probability, it develops the notions of resiliency —a measure of stability of judgements—and robustness —a measure of expected stability. It then becomes possible to understand subjects' behaviour in the Wason selection task, in examples which have been claimed to involve a 'base-rate fallacy', in (...) appearing to ignore laws of large numbers and to overestimate their own success rate as entirely rational: a matter of combining first-order probability assignments with judgements about the robustness of those assignments.

This paper aims to make explicit the methodological conditions that should be satisfied for the Bayesian model to be used as a normative model of human probability judgment. After noticing the lack of a clear definition of Bayesianism in the psychological literature and the lack of justification for using it, a classic definition of subjective Bayesianism is recalled, based on the following three criteria: an epistemic criterion, a static coherence criterion and a dynamic coherence criterion. Then it is shown that (...) the adoption of this framework has two kinds of implications. The first one regards the methodology of the experimental study of probability judgment. The Bayesian framework creates pragmatic constraints on the methodology that are linked to the interpretation of, and the belief in, the information presented, or referred to, by an experimenter in order for it to be the basis of a probability judgment by individual participants. It is shown that these constraints have not been satisfied in the past, and the question of whether they can be satisfied in principle is raised and answered negatively. The second kind of implications consists of two limitations in the scope of the Bayesian model. They regard (1) the background of revision (the Bayesian model considers only revising situations but not updating situations), and (2) the notorious case of the null priors. In both cases Lewis’ rule is an appropriate alternative to Bayes’ rule, but its use faces the same operational difficulties. (shrink)
