Just passing by ... :-)-This subject begs questions like is anything conscious, a la Susan Blackmore?-What is difference between everything being conscious and nothing being conscious?-Is consciousness anything other than an exchange of energy?-In his book Dennett described the idea, that if a philosopher's zombie could respond exactly like a conscious human being then to all intents and purposes that zombie is conscious. For the life of me the logic then flows backwards too, it becomes difficult to distinguish between a conscious being and a philosopher's zombie!-have fun-rom
