 Like Boghossian and Chudnoff, and unlike Williamson, Albert Casullo thinks that there is a significant difference between a priori and a posteriori justification based on the difference between support by nonexperiential and experiential evidence. He also thinks that there is something like justification (namely, positive epistemic status) that does not rest on evidence at all (2012c: 318–326). For Casullo and others, positive epistemic status can stem from what you are entitled to accept given certain ends or projects. This sort of view will be discussed in  Section 4.5  below.
