No such thing as consciousness? I can understand an idea that consciousness is somehow pervasive, along the lines of panpsychism - but that doesn't make it nonexistent. Or, in the other direction, consciousness can be binary and rare but not particularly special, if it emerges from a confluence of lesser phenomena - but then it does still exist, and we're arguing only over its value. Do you not doubt, ergo think, ergo be? Who is reading this sentence?
