The Zebra* case does satisfy condition (c*) because R is incompatible with a presupposition of the cognitive project of obtaining perceptual justification for P3

With (c*) in the place of (c), Fox no longer instantiates the disjunctive template. For the truth of R—the proposition that the animal in the garbage is not a fox—appears to jeopardize no presupposition of the cognitive project of obtaining a perceptual justification for P7. Thus (c*) is not fulfilled. On the other hand, arguments that intuitively do not transmit do satisfy (c*). Take again Zebra*. In that case R is the proposition that the animals in the pen are mules cleverly disguised so as t
