In order to operate within “the logical space of reasons,” one must be at home with normative discourse, responsive to reasons as such, sensitive to standards of correctness and appropriateness.  This requirement imposes a coherentist/holist condition that precludes the possibility of atomistically isolable cognitive states: any cognitive state, including bottom-level, non-inferential IPM beliefs, can be cognitive only as one element in a complex, reflexively structured system of such states responsive to epistemic norms and goals.
