    There’s fundamentally not much difference between our brain and a fly’s, at the cellular level.

    There’s fundamentally not much difference between the silicon in an n64 and the silicone in a quantum computer… That doesn’t mean you can make a quantum computer out of an old n64.

    However, consciousness is likely just an internal illusion.

    Internal… as it can only be confirmed by the individual self? Consciousness is an ontological term to define the human condition. There is purposely no exact definition, as an exact definition of consciousness would only be utilized to strip rights away from those who do not fall under the exacting definition. There are however generally agreed upon criteria and criteria that have been hotly debated for hundreds of years.

    There’s no obvious reason we can’t scale up from a fly to a human brain, other than difficulty.

    To make this claim requires someone to have a limited understanding of what consciousness is, and how it develops. It completely ignores the mind body problem, and treats the human brain as something that can operate outside the body as if it were some sort of computer.

    Consciousness in humans develops and sustains itself as we physically interact with the world around us. This is true in both development in childhood and as we continue to age. As we physically interact with phenomena around us we mentally develop, as our senses start to fail us in age we mentally decline. Even if I were to just cut off your arm, there would be a plethora of changes to the physiology of your brain that would alter the way it functions and the way it is shaped.

    A person born stripped of all physical phenomena would never develop a conscious to begin with, and a if it were stripped away after consciousness had developed they would lose it. Hell, even sticking someone in an area with restricted physical phenomena for a short period of time can drive them insane.

    Consciousness is not purely a metaphysical phenomenon. And from what we currently understand of it can not be recreated purely in a virtual format.

      You’re mixing up two different things. One is normal brain development, and the other is consciousness itself. It’s true that a human being needs certain external stimuli for the brain to develop in a healthy way and for mental experience to be normal and stable. But that does not mean that, without those stimuli, consciousness does not exist.

      A person can still be conscious and yet suffer severe cognitive, emotional, or behavioral changes because of sensory deprivation or an extremely limited environment. What changes is the quality of development, mental functioning, and maybe the kind of consciousness they have, not necessarily the existence of consciousness itself.

      Also, there is no clear way to measure how much, how little, or whether someone has “no” consciousness at all. Because of that, claiming that a lack of stimuli means a lack of consciousness goes beyond what can actually be established.

      So your argument seems to confuse “without stimuli, there is no normal development” with “without stimuli, there is no consciousness.” Those are not the same thing.

It’s true that a human being needs certain external stimuli for the brain to develop in a healthy way and for mental experience to be normal and stable. But that does not mean that, without those stimuli, consciousness does not exist.

        Human beings require external stimuli for any higher brain development to happen, not just healthy brain development.

        But that does not mean that, without those stimuli, consciousness does not exist.

        Yes… It does. Any example you would like to share of a conscious individual who lacks access to any and all external stimuli?

        A person can still be conscious and yet suffer severe cognitive, emotional, or behavioral changes because of sensory deprivation or an extremely limited environment.

        Yes, but they did not develop in that extreme deprivation. And even if they did develop in a way that was restricted, they did not lack external stimuli completely.

        Your body literally need to be experience external stimuli to develop the capacity for consciousness.

          Yes, I have to admit that I don’t have any example of consciousness in an individual completely without external stimuli. In fact, I agree with you on the last point you made. My point is that we need to be more precise about what we mean by “external stimuli” exactly.

          We could even say that it may be impossible to isolate the mind completely from all stimulation in the first place. That leads to the real issue: perhaps those external stimuli are always present in some form, even if they are extremely minimal, indirect, or invisible to us at first glance.

          So I correct myself, the argument is not necessarily that consciousness can exist with literally no input whatsoever, but rather that what we call “external stimuli” may include things so subtle that they are easy to overlook. In that sense, the claim becomes less about the absence of stimulation and more about how little stimulation is actually enough to sustain consciousness or mental activity.
