ABSTRACT
The aim of this chapter is to defend the Cartesian view that a subject is infallible with respect to the contents of her own occurrent thoughts. These days, such a Cartesian claim is often met with stunned disbelief. But this is likely due to evidence-based antagonism, and to the absence of an adequate, positive defense. Yet whereas antagonism was mitigated in the last chapter, it is my aim here to supply the positive defense.
