 In other words, what problem consciousness entails is that objects are always more than “an object for a subject,” and even the natural attitude toward the world takes this for granted. The burden of proof is thus on idealism to show that there is no such thing. This is in fact impossible, since even idealism assumes at the very least that the cognizing subject is something “in itself,” otherwise there is nothing but an infinite regress of representations (ME30b-c). The regress has to stop with something that “is,” and we need ontology to determine what this means.
