 Dretske did not clearly delineate the class of propositions he called “limiting” (in 2003) or “heavyweight” (in 2005). Some of the examples he provided are “There is a past,” “There are physical objects,” and “I am not being fooled by a clever deception.” He appeared to think that these propositions have a property we may call “elusiveness,” where p is elusive for me if and only if p’s falsity would not change my experiences. But being limiting does not coincide with being elusive. If there were no physical objects, my experiences would be changed dramatically, since I would not exist. So some limiting propositions are not elusive. As to whether all elusive claims are limiting, it is hard to say, because of the squishiness of the term “limiting”. Not-mule is elusive, but is it limiting?
