 If one thinks that some sort of justification can derive from what is default reasonable or through relevant entitlements, one might adopt Casullo’s view that there are different types of knowledge or justification, broadly construed: a priori which rests on nonexperiential evidence; a posteriori which rests on empirical evidence; and a third type of justification that does not rest on any evidence (Casullo 2012c: 324–326). This section has raised some problems for this third conception of justification.
