According to a widespread, broadly Humean consensus, desires and other conative attitudes seem as such to be free from any normative constraints of rationality. However, rational subjects are also required to be attitude-coherent in ways that prima facie hold sway for desire. I here examine the plausibility of this idea by proposing several principlesfor coherent desire. These principles parallel principles for coherent belief and can be used to make a case for a kind of purely conative normativity. I consider several (...) objections to a principle for consistent desiring and reply to them. I conclude that, if attitude-coherence is a mark of rationality, the broadly Humean consensus must be rejected. (shrink)

This paper explores the different ways in which conditionals can be carriers of good and bad news. I suggest a general measure of the desirability of conditionals, and use it to explore the different ways in which conditionals can have news value. I conclude by arguing that the desirability of a counterfactual conditional cannot be reduced to the desirability of factual propositions.

This paper has three interdependent aims. The first is to make Reichenbach’s views on induction and probabilities clearer, especially as they pertain to his pragmatic justification of induction. The second aim is to show how his view of pragmatic justification arises out of his commitment to extensional empiricism and moots the possibility of a non-pragmatic justification of induction. Finally, and most importantly, a formal decision-theoretic account of Reichenbach’s pragmatic justification is offered in terms both of the minimax principle and the (...) dominance principle.

I argue that desire sometimes amounts to knowledge, in the same sense that belief sometimes amounts to knowledge. The argument rests on two assumptions: that goodness is the correctness condition for desire and that knowledge is apt mental representation. Desire that amounts to knowledge—or ‘conative knowledge’—is illustrated by cases in which someone knows the goodness of something despite not believing that it is good.

The Desire-as-Belief thesis (DAB) states that any rational person desires a proposition exactly to the degree that she believes or expects the proposition to be good. Many people take David Lewis to have shown the thesis to be inconsistent with Bayesian decision theory. However, as we show, Lewis's argument was based on an Invariance condition that itself is inconsistent with the (standard formulation of the) version of Bayesian decision theory that he assumed in his arguments against DAB. The aim of (...) this paper is to explore what impact the rejection of Invariance has on the DAB thesis. Without assuming Invariance, we first refute all versions of DAB that entail that there are only two levels of goodness. We next consider two theses according to which rational desires are intimately connected to expectations of (multi-levelled) goodness, and show that these are consistent with Bayesian decision theory as long as we assume that the contents of 'value propositions' are not fixed. We explain why this conclusion is independently plausible, and show how to construct such propositions. (shrink)
