    How not to reject the a priori
    Kriterion: Journal of Philosophy 59 (140): 365-384. 2018.
    According to one influential argument against the existence of a priori knowledge, there is no a priori knowledge because (i) no belief is immune to revision, and (ii) if there were a priori knowledge, at least some beliefs would be unrevisable. The aim of this paper is to examine and reject this argument against the a priori. It is given special attention to premise (ii) of the argument. Philip Kitcher has famously defended a version of this premise. His arguments are assessed and rejected. The…Read more

The main aim of this paper is to challenge the analytic acc…Read more

    Understanding the Revisability Thesis
    Grazer Philosophische Studien 95 (2): 180-195. 2018.
    W. V. Quine famously claimed that no statement is immune to revision. This thesis has had a profound impact on twentieth century philosophy, and it still occupies centre stage in many contemporary debates. However, despite its importance it is not clear how it should be interpreted. I show that the thesis is in fact ambiguous between three substantially different theses. I illustrate the importance of clarifying it by assessing its use in the debate against the existence of a priori knowledge. I…Read more
