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
