This article offers a critical analysis of John Broome's conception of practical reasoning. I first introduce his main claims and then point out some of the difficulties raised by the notion of “double expression” and by some aspects of the cognitivism which he explicitly endorses. I then emphasize two consequences of these criticisms: one concerning the link he sees between belief and intention, and the other concerning the idea that our practical reasonings are inextricably linked to our theoretical reasonings. Finally, (...) I argue that the problem Broome seems to be facing has its source in the difficulty of distinguishing clearly between reasoning (a relation between mental states) and the description of its content (a relation between propositions).

The thesis asserting the mental dependence of institutional entities is particularly debated in social ontology. One of its implications is the infallibility thesis, according to which the existence of institutional entities requires that some of their properties be known. What are these properties? After presenting the Searlian conception of institutional entities and the kind of mental dependence they manifest, I specify the content of the infallibility thesis. I then show that these properties are the deontic powers associated with these entities, (...) and that the mental attitude towards deontic powers must take the form of practical knowledge. Finally, I show that this interpretation is compatible with the existence of at least some naturalized institutional entities. (shrink)
