    Why argue so convoluted. Our sensory organs transmit the signal by means of a biochemical electrical charge and our brains are able to interpret that signal in such a fashion that it provides us with knowledge about our environment. Don't have to make it more complicated than that.

    mathematician's played around with numbers as an abstract exercise long before they applied it to the real world (?)3017amen

    Maybe not so much numbers, for even the proverbial caveman had the idea of quantity and the ability to represent it to himself. I mean....who goes hunting with only one measly arrow? And if you’ve got two hands, why not carry two spears?

    Geometry, on the other hand, well.........

    “....A new light must have flashed on the mind of the first man (Thales, or whatever may have been his name) who demonstrated the properties of the isosceles triangle. For he found that it was not sufficient to meditate on the figure, as it lay before his eyes, or the conception of it, as it existed in his mind, and thus endeavour to get at the knowledge of its properties, but that it was necessary to produce these properties, as it were, by a positive a priori construction; and that, in order to arrive with certainty at a priori cognition, he must not attribute to the object any other properties than those which necessarily followed from that which he had himself, in accordance with his conception, placed in the object....”

    This is not to say all those produced properties arrived out of the blue. But however much trial-and-error the old geezer did, all of it without exception, was pure thought, and all could have been derived from a single example of a single triangle. What’s really amazing....sorta.....is, Thales lived around 600BC, but square roots had been known for 1000 years before that. So arriving at 1,1, sq rt 2 for one of the properties of the isosceles triangle, while seeming quite unlikely, actually wasn’t.

    So, yeah, no doubt. The abstract mathematical playground was in use long before its application to the natural empirical one.

    Beings are conscious, that’s why they’re called ‘beings’. ‘Eyes’ are conscious, they’re organs.

    "You equate "physical" and "actual", and I agree. But if a simulated electron is not physical & actual, what is it?" --Gnomon
    It's virtual. It means it is represented as information by some other physical form rather than its actual form.
    Zelebg
    I'm beginning to see a part of our communication glitch. You seem to think that a "virtual electron" --- as represented by illuminated pixels on a computer screen --- is still an electron in a different physical form. Yet, those screen pixels have none of the physical properties of an actual electron. Instead, they only have the potential to cause the metaphysical idea of an electron to be generated in the mind of the observer. The graphic symbol is merely an illusion or appearance, due to its conventional association with a real object. I'm sure you know this, but your terminology is misleading.

    The physical pixels are not the thing represented, but a coded message (information) that triggers the idea of an electron in a conscious mind. So, the physical representation on the screen (symbol) is converted into an abstract idea (eidos) in a conscious mind. Hence, a virtual electron is not, as you suggested, an electron in an alternative "physical form" in space-time, but merely a pointer to a meta-physical form in consciousness. A simulated electron is not a virtual electron, but an abstract sign directing your mind to recall the idea of an actual object that you are already familiar with. :nerd:


    Virtual : not physically existing as such but made by software to appear to do so.
    ___Google

    Symbol : a thing that represents or stands for something else, especially a material object representing something abstract.
    ___Google

    PS___ Your definition of "virtual" above is like saying a statue of an invisible god, is still the god, but in a different form. Early Christians ridiculed pagans for equating the powerless symbol with a powerful deity. Our God, they said, is a spirit and will never be found in a physical form. Ironically, the Christians could see the error in pagan idolatry, but not in their own equation of human Jesus with divine Jehovah : spirit in the flesh. :smile:

    Nonsense. You can take frog’s eyes out and place them in solution, and the photo-receptors will still respond to simulation, but ‘responding to stimuli’ doesn’t constitute ‘consciousness’. Consciousness is holistic, it manifests as the interaction of all manner of cells and organs as an orchestrated whole which is what 'being' refers to. There are 'conscious beings' but not 'conscious organs'. That is the mereological fallacy in a nutshell.

    No. "The hard problem ...

    You might have missed the scientific paper I mentioned above, which mentions the 'hard problem' in particular connection to what is called the 'neural binding problem'. The paper is here, from which I quote:

    We will now address the deepest and most interesting variant of the NBP, the phenomenal unity of perception. There are intractable problems in all branches of science; for Neuroscience a major one is the mystery of subjective personal experience. This is one instance of the famous mind–body problem (Chalmers 1996) concerning the relation of our subjective experience (aka qualia) to neural function. Different visual features (color, size, shape, motion, etc.) are computed by largely distinct neural circuits, but we experience an integrated whole. This is closely related to the problem known as the illusion of a stable visual world (Martinez-Conde et al. 2008). ....

    Traditionally, the NBP concerns instantaneous perception and does not consider integration over saccades. But in both cases the hard problem is explaining why we experience the world the way we do. As is well known, current science has nothing to say about subjective (phenomenal) experience and this discrepancy between science and experience is also called the “explanatory gap” and “the hard problem” (Chalmers 1996). There is continuing effort to elucidate the neural correlates of conscious experience; these often invoke some version of temporal synchrony as discussed above.

    There is a plausible functional story for the stable world illusion. First of all, we do have a (top-down) sense of the space around us that we cannot currently see, based on memory and other sense data—primarily hearing, touch, and smell. Also, since we are heavily visual, it is adaptive to use vision as broadly as possible. Our illusion of a full field, high resolution image depends on peripheral vision—to see this, just block part of your peripheral field with one hand. Immediately, you lose the illusion that you are seeing the blocked sector. When we also consider change blindness, a simple and plausible story emerges. Our visual system (somehow) relies on the fact that the periphery is very sensitive to change. As long as no change is detected it is safe to assume that nothing is significantly altered in the parts of the visual field not currently attended.

    But this functional story tells nothing about the neural mechanisms that support this magic. What we do know is that there is no place in the brain where there could be a direct neural encoding of the illusory detailed scene (Kaas and Collins 2003). That is, enough is known about the structure and function of the visual system to rule out any detailed neural representation that embodies the subjective experience. So, this version of the NBP really is a scientific mystery at this time.

    Bolds added. So here we have "scientist acknowledges 'scientific mystery'". Maybe you could explain to him that he ought to be doing his job better. :wink:

    Pointer points FROM something to something. Do you understand the difference when that pointer of yours points from, say an actual chair in a room, and virtual chair on a computer screen?Zelebg
    Yes. A symbol points to something else. But it is not the actual something else. And the something else is not necessarily concrete or real. It may be an idea or concept. In that latter case, the physical symbol points to a meta-physical concept. The pointer points FROM something symbolic or virtual, TO something semantic, which is an abstraction pointing BACK TO something real or physical. The "difference" is between Mind & Matter, Substance & Attribute, Potentiality & Actuality. "Vive la difference!"

    If you point a camera at an actual physical chair in a room, and display the collected optical information on a TV screen, the image on the screen may be defined as a "virtual" chair, but you can't sit on it. The image is a simulation, or a symbol, or an illusion of a chair. The symbol has a physical reality, but not that of a chair. The symbol only serves to remind you of the idea of a chair. The meaning of "chair" is already in your memory as a pattern of abstract information, but not as a little chair inside the head.

    In computer theory, a symbolic reference is sometimes called a "semantic pointer". It redirects to the metaphysical meaning of a thing, but not to the thing itself. Meaning is in the mind, not the brain. A symbol is not the thing symbolized. A virtual thing is not the thing symbolized. A virtual electron is not an actual electron; it's the idea of an electron. You might say it's the Platonic form of an electron. :nerd:

    Note : a Virtual Electron is a potential particle, not an actual particle.
