In the ongoing debate, there are a set of mind-body theories sharing a certain physicalist assumption: whenever a genuine cause produces an effect, the causal efficacy of each of the nonphysical properties that participate in that process is determined by the instantiation of a well-defined set of physical properties. These theories would then insist that a nonphysical property could only be causally efficacious insofar as it is physically implemented. However, in what follows we will argue against the idea that fine-grained mental contents could be physically implemented in the way that functional properties are. Therefore, we will examine the metaphysical conditions under which the implementing mechanism of a particular instance of a functional property may be individuated, and see how genuine beliefs and desires—insofar as they track the world—cannot meet such conditions.

In this paper, I want to challenge some common assumptions in contemporary theories of practical rationality and intentional action. If I am right, the fact that our intentions can be rationalised is widely misunderstood. Normally, it is taken for granted that the role of rationalisations is to show the reasons that the agent had to make up her mind. I will argue against this. I do not object to the idea that acting intentionally is, at least normally, acting for reasons, but I will propose a teleological reading of the expression ‘for reasons.’ On this reading, it is quite possible to act for reasons without having reasons to act. In a similar way, paradigmatic cases of cogent practical reasoning do not require the transference of justification from the premises to the practical conclusion.

In my opinion, Richard Moran’s account of the connections between self-knowledge and intentional ac-tion presents a certain unresolved tension. On the one hand, the epistemic privilege of the first person derives from the fact that forming an intention is a matter of the subject endorsing a course of action. An en-dorsing subject is not a mere observer of her intentions. On the other hand, the transparency of endorsement is assimilated to the putative fact that an agent forms her intentions by reflecting on the reasons to make up her mind. The resulting picture is an extremely rationalistic account of intentional action. I will try to defend that this form of practical rationalism can be avoided without renouncing the basic intuitions behind Moran’s use of the notion of endorsement.
