I still have problems understanding why external world skepticism is a thing in philosophy. I've heard so many hypotheses and they all seem to revolve around the idea that consciousness is a "simulatable". Here's what I don't understand: The keywords are: Consciousness: the state of being aware of and responsive to one's surroundings. Simulation: imitation of something else. Simulation, by definition, is the imitation of something else. The "something else" in this case is consciousness. If it's the imitation of consciousness then it cannot be the real one. How on earth can consciousness not be real? It seems to me that by simulation they are trying to say that there is "illusory simulated consciousness" and "real non-simulated consciousness". How on earth can consciousness be illusory/simulated? A lot of people then say: external world skepticism is skepticism about perception not consciousness. It seems to me that perception and consciousness are more or less the same thing. Consciousness is the general state of being aware of and responsive to one's surroundings. Perception is the specific response to one's surroundings or, in other words, "consciousness of" something specific. I don't understand. Is it possible that skepticism is finally dead?
