Abstract

As Descartes famously pointed out in theSecond Meditation,the thought that someone is thinking is true anytime anyone thinks it. Furthermore, thinking it makes it true. Conversely, anytime anyone thinks that it is not the case that someone is thinking, this thought is false, and thinking it makes it false.l will argue that the propositions ‘There is at least one true normative proposition’ and ‘There are no true normative propositions’ have very similar properties. The proposition ‘There is at least one true normative proposition,’ like the proposition ‘Someone is thinking,’ is true anytime anyone believes it, and, in an important sense, it is made true by someone's believing it. Conversely, anytime anyone believes that there are no true normative propositions, the proposition he believes is false and his believing it makes it false.
