We must also mention Gupta 2006. In this work, Gupta argues that an experience provides the experiencer, not with a straightforward entitlement to a proposition, but rather with a hypothetical entitlement: as explicated in Berker 2011, if subject S has experience e and is entitled to hold view v (where S’s view is the totality of S’s concepts, conceptions, and beliefs), then S is entitled to believe a certain class of perceptual judgements, Γ(v). (Berker uses “propositions” instead of “perceptual judgements” in his formulation.) But this generates a problem: how is S entitled to hold a view? There seems to be a circular interdependence between entitlements to views and entitlements to perceptual judgements. Here, Gupta appeals to a general form of revision theory — generalizing beyond both the revision theory of truth and the revision theory of circularly defined concepts (Section 5.4, above) — to given an account of how “hypothetical perceptual entitlements could yield categorical entitlements” (Berker 2011).
