Richard Brown (left) and Keith Frankish (right) on qualia.
Suppose you’re a physicalist and you want to include qualia in your ontology. Unfortunately, “classic qualia” (intrinsic, ineffable, private properties of experience) seem incompatible with physicalism, while “zero qualia” (mere dispositions to judge that we have classic qualia) don’t seem like genuine qualia at all. After all, even zombies have zero qualia! Perhaps you can be satisfied with “diet qualia” (subjective feels of experience). But are there meaningful distinctions between diet qualia and the other two conceptions? Is the notion of diet qualia even coherent? Frankish and Brown discuss the issue.
