 Determining which of these norms governs assertion depends (at least in part) on what we mean by hypothesizing that assertion is governed by a simple norm by N. In the next section  (5.1.3),  we clarify what philosophers typically mean when they say that N governs assertions. In the subsequent section  (5.1.4),  we review the various accounts of which specific norm governs assertion (i.e., the different views as to which property C makes a proposition assertable).
