This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will explain how Peirce tackles this (...) issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.
