In this paper I study intentions of the form, that is, intentions with a we-content, and their role in interpersonal coordination. I focus on the notion of epistemic support for such intentions. Using tools from epistemic game theory and epistemic logic, I cast doubt on whether such support guarantees the other agents' conditional mediation in the achievement of such intentions, something that appears important if intentions with a we-content are to count as genuine intentions. I then formulate a stronger version of epistemic support, one that does indeed ensure the required mediation, but I then argue that it rests on excessively strong informational conditions. In view of this I provide an alternative set of conditions that are jointly sufficient for coordination in games, and I argue that these conditions constitute a plausible alternative to the proposed notion of epistemic support

Dans cet article, je montre que quatre normes de rationalité associées aux intentions peuvent être déduites de normes similaires s’appliquant aux acceptations en contextes délibératifs, un type d’état mental apparenté mais irréductible aux croyances par lequel un agent tient certains faits pour acquis lorsqu’il délibère. Je montre que cette approche, que je nomme le pragmatisme hybride, évite certaines limitations de l’approche la plus prisée dans la littérature, le cognitivisme, et qu’en comparaison avec les approches purement pragmatistes, principales rivales du cognitivisme, le pragmatisme hybride rend mieux justice à nos intuitions relatives aux normes associées aux intentions. Je montre enfin que le pragmatisme hybride permet d’expliquer comment les intentions influencent le raisonnement pratique, et de ce fait, comblent un vide important dans les théories contemporaines.In this paper, I show that four normative requirements on rational intentions follow from similar requirements on acceptations in deliberative contexts, a type of mental state close but irreducible to beliefs by which agents take some facts for granted in deliberation. I show that this approach, which I call hybrid pragmatism, avoid shortcomings of cognitivism, one of the most prominent one in the literature. I show furthermore that in comparison with purely pragmatist approaches, the main rivals of cognitivism, an hybrid form of pragmatism makes better justice to our intuitions regarding the sources of the normative requirements on rational intentions, and that it allows for understanding how intentions influence practical reasoning
