 As noted, even convergence theorists adopt restrictions on the set of justificatory reasons. Some discipline is implicit in the concept of “a reason.” A factual claim does not justify a principle if evidence falsifies the claim, and a normative claim is not a reason to endorse \(L\) if it lacks real normative force. So, we need to articulate some tests that count reasons as justificatory. The entry organizes them by increasing stringency: intelligibility, accessibility, and shareability.
