What is structural rationality? Specifically, what is the distinctive feature of structural requirements of rationality? Some philosophers have argued, roughly, that the distinctive feature of structural requirements is coherence. But what does coherence mean, exactly? Or, at least, what do structuralists about rationality have in mind when they claim that structural rationality is coherence? This issue matters for making progress in various active debates concerning rationality. In this paper, I analyze three strategies for figuring out what coherence means in the (...) debates on structural rationality. I argue that these strategies face problems. (shrink)

Kiesewetter defends the normativity of rationality by presenting a new solution to the problems that arise from the common assumption that we ought to be rational. He provides a defence of a reason-response conception of rationality, an evidence-relative account of reason, and an explanation of structural irrationality in relation to these accounts.

Suppose you intend now to φ at some future time t. However, when t has come you do not φ. Something has gone wrong. This failing is not just a causal but also a normative failing. This raises the question how to characterize this failing. I discuss three alternative views. On the first view, the fact that you do not execute your intention to φ is blameworthy only if the balance of reasons pointed to φ-ing. The fact that you intended (...) to φ does not add to the reasons for φ-ing at t. On the second view, the fact that you do not execute your intention to φ is blameworthy because you violate a requirement of rationality. Both these views have in common that they deny that intending to φ at t creates a reason to φ at t. The third alternative, the one I defend, claims that you often create reasons to φ by intending to φ. (shrink)

Mind reading (i.e. the ability to infer the mental state of another agent) is taken to be the main cognitive ability required to share an intention and to collaborate. In this paper, I argue that another cognitive ability is also necessary to collaborate: representing others’ and ones’ own goals from a third-person perspective (other-centred or allocentric representation of goals). I argue that allocentric mind reading enables the cognitive ability of goal adoption, i.e. having the goal that another agent’s achieve p (...) because and as long as another agent has that goal that p. Having clarified the relevance of mutual goal adoption for acting jointly, I argue that when an intention is shared between several agents, each individual has an intention in favour of the joint action and one in favour of a joint mode of reasoning. This mode of reasoning is allocentric reasoning. Finally, I elaborate on the consequences of this view for the scientific study of human collaboration. (shrink)

The paper criticizes two prominent accounts which purport to explain normativity by appealing to some relation that one bears to oneself. Michael Bratman argues that one has reason to be formally coherent because otherwise one would fail to govern oneself. And David Velleman argues that one has reason to be formally coherent because otherwise one would be less intelligible to oneself. Both Bratman and Velleman argue in quite different ways that rational coherence is normative because it is necessary for the (...) instantiation or promotion of the independently normative self-relation they invoke. But the paper presents a similar scenario which arguably exposes a failure of extensional adequacy common to both accounts: one can instantiate the self-relation in question without being formally coherent. A brief diagnosis is offered for why two such different accounts turn out to be vulnerable to a similar counterexample, suggesting that other accounts which appeal to self-relations in a broadly similar way might also suffer from the problem identified here.
