Hossack (2007) defends what he calls the rationalist thesis: the thesis that necessity reduces to (or at least always coincides with) a priori knowledge. In this paper I discuss some features of Hossack’s rationalist account of necessity. In the first half, I attempt to fill in a missing link in the rationalist thesis, connecting the notions of primitiveness of facts and a priori modes of presentation. In the second half, I complain that the strategy of dissolving counterexamples is not enough, and that a general principle connecting necessity and a prioricity is needed. I suggest further kinds of counterexamples that might arise, but rather than demand a response to each counterexample, I suggest that they highlight the need for a general argument for the rationalist thesis.

Abstract: This paper proposes a way to understand Kant's modalities of judgment—problematic, assertoric, and apodeictic—in terms of the location of a judgment in an inference. Other interpretations have tended to understand these modalities of judgment in terms of one or other conventional notion of modality. For example, Mattey (1986) argues that we should take them to be connected to notions of epistemic or doxastic modality. I shall argue that this is wrong, and that these kinds of interpretation of the modality of judgments cannot be reconciled with a key claim made by Kant, namely, that the modality of a judgment does not contribute to its content, and has nothing to do with the matter that is judged. I offer an alternative interpretation based upon Kant's explicating these modalities in terms of the location of a judgment in an inference, whereby the modality of a judgment is determined by the role a judgment plays in a given course of reasoning. If I am right, then Kant in fact presents an intriguing thesis pertaining to the inferential status and potential of all our judgments
