Abstract

Although the zombie idea seems to fit in with some ‘natural and plain’ intuitions, it conflicts with others. Reinforced by the ‘jacket fallacy’, it both feeds on and feeds an incoherent conception of phenomenal consciousness. The ‘sole-pictures argument’ shows that a certain variety of epiphenomenalism is inconceivable in the relevant sense. Then it is argued that if zombies are conceivable, so is that kind of epiphenomenalism. If the reasoning is sound, the inconceivability of zombies follows. Among other corollaries of the main conclusion is that the idea of the inverted spectrum without physical differences is incoherent too.
