Given the success of the formal approach, within contemporary epistemology, to understanding degreed belief, some philosophers have recently considered its extension to the challenge of understanding intention. According to them, (1) intentions can also admit of degrees, as beliefs do, and (2) these degreed states are all governed by the norms of the probability calculus, such that the rational norms for belief and for intention exhibit certain structural similarity. This paper, however, raises some worries about (2). It considers two schemes (...) for representing degreed intention, and casts some doubt on applying probabilistic norms to degreed intention on each scheme. And it argues that the norms of Intention–Belief Consistency and Enkrasia cannot plausibly be turned into norms prescribing a simple correspondence relation between one’s degrees of belief and intention. The results suggest a potential structural discrepancy between the norms of theoretical and practical rationality—at least for degreed belief and intention. This potential discrepancy not only raises interesting questions about the intention–belief relation and rational norms for degreed intention. It also poses a new challenge for intention-based expressivism about normative judgment and cognitivism about practical rationality. (shrink)

In this article, I first elaborate and refine the Principle of Intention Agglomeration (PIA), which was introduced by Michael Bratman as “a natural constraint on intention”. According to the PIA, the intentions of a rational agent should be agglomerative. The proposed refinement of the PIA is not only in accordance with the spirit of Bratman’s planning theory of intention as well as consistency constraints for intentions rooted in the theory, but also reveals some deep rationales of practical rationality regarding resource-limited (...) agents. Then I defend the PIA against various objections and counterexamples, showing that the refined PIA survives attacks based on both conceptual analyses and psychological considerations. (shrink)

Many philosophers of action afford intentions a central role in theorizing about action and its explanation. Furthermore, current orthodoxy in the philosophy of action has it that intentions play a causal role with respect to the etiology and explanation of action. But action theory is not without its heretics. Some philosophers have challenged the orthodox view. In this paper I examine and critique one such challenge. I consider David-Hillel Ruben's case against the need for intentions to play a causal role (...) in the etiology and explanation of mental actions. Contra Ruben, I defend the orthodox view that intentions play an indispensable causal and explanatory role with respect to mental actions. (shrink)

In this article, I challenge the dominant view of the importance of the debate over action-individuation. On the dominant view, it is held that the conclusions we reach about action-individuation make little or no difference for other debates in the philosophy of action, much less in other areas of philosophy. As a means of showing that the dominant view is mistaken, I consider the implications of accepting a given theory of action-individuation for thinking about doxastic agency. In particular, I am (...) interested in the implications for thinking about the variety of evaluative control we can exercise over the formation of our doxastic attitudes. I show that our assumptions about how to individuate actions matters for how we think about doxastic agency and, hence, the conclusions we reach about action-individuation are of greater significance than some have thought.
