Some descriptions that apply to certain perception-illusion disjunctions

In this chapter, certain propositions are assumed to be true in a hypothetical case, and some of their properties are set forth. In blunt perception–illusion disjunctions, the ‘or’ has just the sense of the logical constant ‘v’; to suppose such a disjunction to be true is to suppose no more and no less than that its limbs or disjuncts are not both false. The ‘or’ in a pointed perception–illusion disjunction gets as close to that as it can. The illusion, and it might be the perfect illusion, of (seeing) a flash of light when an electric current is passed through one's head in a certain way by experimental psychologists. They call it giving you a ‘phosphene’, etymologically a light-appearance. No light is involved. The point is that the descriptions are all ones which have been thought to apply to a suppositious class of statements, experience-reports in a narrow sense.
