Parentheticalism, Normative Reasons, and Error Cases
This chapter discusses another crucial use of parenthetical sentences in normative reasons-discourse. Due to their feature of subject-orientation, they enable us to cite known falsehoods as normative reasons without violating the factivity requirements of reasons-discourse. This is important, because it allows us to deal with error cases in a way that does not entail that putatively rational agents systematically misidentify their reasons. Ontological and linguistic objections to the idea that falsehoods can be full-blooded normative reasons for agents are discussed and rejected. A notion of quasi-factivity is introduced to characterize the requirements of reasons-discourse. Parentheticalism is shown to enable a unified account of normative reasons-discourse, avoiding divergences between veridical and error cases.
