 As in the case of meaning, we may distinguish between more or less direct arguments. One way to provide a direct argument for CE normativity would be to proceed from the notion of correctness conditions, in analogy with the simple argument (Boghossian 2003: 85). Just as meaningful expressions have correctness conditions essentially, along the lines of  (CM),  so do concepts: The concept green, for instance, applies to an object \(x\) if and only if \(x\) is green. However, unlike in the case of (CM), the application relation here is just that between a concept and the objects that “fall under” it. For normativity to enter some connection has to be made with the subject who employs the concepts, with her mental states.
