  • Sometimes strokes can destroy the area of the brain that controls hunger. They require alarms to consistently eat, sleep, etc. I remember one story about a guy who put all these alarms on his watch. One day, his watch runs out of batteries, so his alarms stop completely. A couple days later, he calls the hospital because he couldn’t get out of bed. Turns out he hadn’t eaten anything the whole time. In short, you’ll probably forget to eat without any signal you have to.






  • I’m not sure I entirely understand your argument. “We decide it exists, therefore it exists” is the basis of all science and mathematics. We form axioms based on what we observe, then extrapolate from those axioms to form a coherent logical system. While it may be a leap of logic to assume others have consciousness, it’s a common decency to do that.

    Onto the second argument, when I mean “what signal is qualia” I’m talking about what is the minimum number of neurons we could kill to completely remove someone’s experience of qualia. If we could sever the brain stem, but that would kill an excess of cells. We could kill the sensory cortex, but that would kill more cells than necessary. We could sever the connection between the sensory cortex and the rest of the brain, etc. As you minimize the number of cells, you move up the hierarchy, and eventually reach the prefrontal cortex. But once you reach the prefrontal cortex, the neurons that deliver qualia and the neurons that register it can’t really be separated.

    Lastly, you said that assuming consciousness is some unique part of the universe is wrong because it cannot be demonstrably proven to exist. I can’t really argue against this, since it seems to relate to the difference in our experience of consciousness. To me, consciousness feels palpable, and everything else feels as thin as tissue paper.


  • Here’s another way of framing it: qualia, by definition, is not measurable by any instrument, but qualia must exist in some capacity in order for us to experience it. So, me must assume that either we cannot experience qualia, or that qualia exists in a way we do not fully understand yet. Since the former is generally rejected, the latter must be true.

    You may argue that neurochemical signals are the physical manefestation of qualia, but making that assumption throws us into a trap. If qualia is neurochemical signals, which signals are they? By what definition can we precisely determine what is qualia and what is not? Are unconscious senses qualia? If we stimulated a random part of the brain, unrelated to the sensory cortex, would that create qualia? If the distribution of neurochemicals can be predicted, and the activations of neurons was deterministic as well, would calculating every stimulation in the brain be the same as consciousness?

    In both arguments, consciousness is no clearer or blurrier, so which one is correct?
