  But while many have felt the force of this “just too different” intuition, it’s unclear what that charge amounts to. In what sense are the natural and the normative “just too different?” Schroeder thinks that the “too different” intuition has force only if there is “a perfectly general single truth about which any reductive view would be forced into error” (Schroeder 2005, 14). The existence of such a truth would be the proof that the natural and normative are just too different; without such a truth, the non-naturalist hasn’t offered much by way of an argument against naturalism. But because all normative claims conceptually reduce to claims about reasons, argues Schroeder, there will be no such general truth, provided that we have a coherent account of the foundational notion of a reason. If all normative claims are conceptually reducible to claims about reasons, then a coherent account of reasons can explain all normative claims, without error. These fundamental normative facts about reasons are themselves explained by the natural facts to which reasons reduce. But because this reduction of reasons will take the form of a synthetic reduction, there end up being no conceptual connections between the normative and the natural. This general lack of conceptual connections between the normative and the natural is what explains the presence of the “just too different” intuition, and it is fully compatible with moral naturalism as a synthetic metaphysical truth.
