Having suggested that a salient feature of philosophical naturalism is to deny that there are non‐natural norms, I make a distinction between a moderate naturalism, which admits the existence of natural norms , and a radical naturalism which denies it . On the assumption that intentional facts are irreducibly normative, their existence would thus seem to raise a problem for moderate epistemological naturalism. I argue that no non‐trivial naturalistic explanation of conceptual intentionality is to be possible unless it is denied that norms of rationality are constitutive of intentional content. It follows that the only form of intentional naturalism that is not obviously untenable has to be radical. Other aspects of Quine's doctrine suggest that the introduction of epistemic norms into our “system of the world” is either dubiously coherent, or “merely programmatic”

The question to be discussed is whether the distinction between the conceptual and the nonconceptual is best understood as pertaining primarily to intentional contents or to intentional states or attitudes. Some authors have suggested that it must be understood in the second way, in order to make the claim that experiences are nonconceptual compatible with the idea that one can also believe what one experiences. I argue that there is no need to do so, and that a conceptual content can be understood as being simply one which is composed of concepts, without compromising this intuitive view of the relation between beliefs and experiences.
