Parentheticalism and Requirements of Rationality

Abstract

It is suggested that parentheticalism obviates the need to think of rationality as a distinct normative category, different from the category of support by normative reasons. So-called structural requirements are discussed as a potential obstacle to this proposal. It is shown that a parentheticalist account of the antecedents of rationality conditionals can explain away the impression that there are structural requirements of rationality. This account also solves the bootstrapping problem without introducing wide-scope oughts or the like. A notion of pseudo-detachment is introduced to describe the inferential behavior of the relevant conditionals. It is also explained how parentheticalism can capture the elusive idea of taking the subject’s point of view.
