What is called consciousness is just the idea of intentionality, that is that objects are revealed in transparency, if not in 'reality' then in phenomenologically reduced actuality. But if such an object were revealed then its corresponding subject would also be revealed - for something to be known there must be a basis for trusting the knowing. Since there is no, and can be no, revelation of a subject there is also no object. It is the apparent clarity with which objects appear that is the only evidence for a subject and if this evidence is inadmissable then the appearance of the object must be doubted. There is nothing, not even a cross-sectional adumbration of an object that appears in complete transparency.  Hence consciousness does not exist, it is a myth or a deferral of transparency. Well, you might say, there is clearly something. If not consciousness what is it? Experience without any idea of experience.
