Donald Davidson contributed more deeply to our understanding of language, thought, and reality than perhaps any other recent philosopher. His discussions of skepticism are sometimes seen as peripheral to those contributions. As I read him, Davidson argued against three skeptical worries. First, beliefs are true or false relative to a conceptual scheme. Second, beliefs generally are false. Third, other minds and an external world do not exist. Call those worries ‘conceptual relativism’, ‘falsidicalism’, and ‘solipsism’, respectively. I investigate how Davidson’s arguments (...) are connected. I then show that those connections are so systematic that Davidson ultimately offers a single, master argument with two premises. Premise one is that I think. Premise two is an application of his account of radical interpretation. Focusing on the systematicity of Davidson’s anti-skeptical arguments demonstrates that discussions of skepticism were more central to his views than often appreciated and shines fresh light on his project overall.

I articulate and argue for a modest use to which philosophers who are not historians of philosophy might put the history of philosophy. That use is in conceptual cartography. I understand conceptual cartography to be the practice of mapping how concepts, including those as complex as philosophical views, relate. Using the history of philosophy in conceptual cartography uses that history to situate landmarks on a conceptual map, and then situates other views (historical or contemporary) relative to those landmarks. After articulating (...) and arguing for this use, I consider objections. (shrink)

If it seems unquestionable that C. I. Lewis is a Kantian in important respects, it is more difficult to determine what, if anything, is original about his Kantianism. For it might be argued that Lewis’ Kantianism simply reflects an approach to the a priori which was very common in the first half of the twentieth century, namely, the effort to make the a priori relative. In this paper, I will argue that Lewis’ Kantianism does present original features. The latter can (...) be detected by focusing on Lewis’ account of the method of philosophy in the first chapter of Mind and the World Order. In that context, Lewis argues that the method of philosophy should be reflective and critical. It will be my contention that this understanding of philosophy involves a therapeutic perspective, which bears important resemblances to Kant’s account of transcendental reflection in the Amphiboly of the Critique of Pure Reason. I will illustrate how this therapeutic application of reflection works in Lewis’ metaphysics. In this context, reflection can correct errors of reasoning that occur when we are operating within a particular conceptual scheme and use the criteria of reality that are appropriate in another.
