 On the issue of evidence-possession generally: if we regard evidence as wholly constituted by mental states (experiences, beliefs, memories, etc.), then an account of what it is to “possess” evidence will be relatively straightforward—we must simply have these mental states. If evidence is not merely in the head, so to speak, then the possession condition in Evidentialist norms may turn out to be quite complex. What is our evidence for the belief that “it's raining”? Is it our awareness or experience of something, such as the street's being wet? Or is it simply the street's being wet? When asked why we believe that it is raining, we typically say something like “because the street is wet.” Is this merely shorthand or does it say something about the nature of evidence? (For arguments that extra-mental facts in the world often constitute evidence, see McDowell 1994 and Ginsborg 2007; for further discussion see Williamson 2000 and Dancy 2000, ch.6).
