As a non-representationalist form of integrating methodological naturalism with ontological naturalism, this work proposes a distinction between phenomenic and rational intuitions. Since this is not a static distinction, it offers a way of observing in which sense the apparent circularity between mental and theoretical representations is not a vicious one. The argument’s plausibility will have to be reinforced through considerations about the unstability of ontologies and about how to conceive conflicting intuitions.
