  • I wasn’t arguing from a non-scientific point view at all. Reality is there. That doesn’t make the problem any less “hard”. But I think it is “hard”, not “impossible”.

    And as any modern physicist will tell you: most of reality is indeed invisible to us. Most of the universe is seemingly comprised of an unknown substance, and filled with an unknown energy. Most of the universe that we can see more directly follows rules that are unintuitive and uses processes we can’t see. Not only can’t we see them, our own physics tells is it is literally impossible to measure all of them consistently.

    Yet despite this, physics works. We can use our minds and tools to reveal the invisible truth. That’s why I believe in the scientific method, and why I think consciousness is not necessarily an impossible problem (unlike Nagel).

    But subjective consciousness and qualia fit nowhere in our modern model of physics. It’s potentially “nature of reality”-level stuff – and I don’t mean hippy quasi-scientific mumbo jumbo by this, I mean it seems to reach right down deep into the fundamentals of what physics is and seeks to achieve, to a level that we have not yet uncovered.

    I don’t think it’s impossible to explain consciousness. It is part of the universe and the universe is there for us to study. But we are not ready to answer the question. We don’t even fully understand what the question is really asking. It sidesteps our current model of physics. Obviously it is intimately connected to processes in the brain somehow… but that somehow is, currently, an absolute mystery.

    I don’t subscribe to Nagel’s belief that it is impossible to solve, but I do understand how the points he raises are legitimate points that illustrate how consciousness does not fit into our current scientific model of the universe.

    If I had to choose anyone I’d say my thoughts on the subject are closest to Roger Penrose’s line of thinking, with a dash of David Chalmers.

    I think if anyone doesn’t see why consciousness is “hard” then there are two possibilities: 1) they haven’t understood the question and its scientific ramifications 2) they’re not conscious.



  • You are wading in with extreme arrogance in an area you clearly know very little about.

    Many of the most prominent ideas in the field of consciousness are from physicists, biologists, and other scientific fields. The issues are in some cases fundamental to the philosophy of science itself. This is the very bleeding edge of science, where hard physics and metaphysics collide.

    Why do you think consciousness remains known as the “hard problem”, and still a considered contentious mystery to modern science, if your simplistic ideas can so easily explain it?

    Do you think your naive ideas have not already been thoroughly debated and explored by scientists and philosophers over years of debate and research? The extremely simplistic and basic points you have raised (even ignoring the fallacious ones) are easily invalidated by anyone with even a basic grasp of this field (or indeed basic logic or scientific methodology).

    Besides the above, you have clearly not understood the main point of my comment, not engaged in any actual logical debate or analysis of the issues raised (indeed you don’t even to comprehend or recognise what these are) and demonstrated a near total ignorance of modern theories of consciousness.

    You had a chance to open your eyes to a whole realm of knowledge and discovery in a fascinating field at the cutting edge of modern science and reason and you just utterly failed to engage with it, handwaving it away with ignorance and stupidity.


  • Petroleum is what makes cars move, obviously. That’s it!

    All those engineers and mechanics who waffle on about physics, laws of motion, and engines and stuff are all a bunch of idiots. I have no respect for them. I don’t need to know about that stuff to talk about how cars work!

    You just put petrol in it, it burns and it moves. Burning petrol is what makes cars move. That’s all we’re talking about here! The extent of our debate is whether or not petrol makes cars move. Not how it makes cars go, that’s a wider debate for non-idiots.

    (Electric cars? Nonsense. Where’s the gas tank?)

    (Boats? No, they’re completely different. I mean yes you put the same fuel in them, but they’re clearly not cars, so it’s not the same.)



  • No it hasn’t, and if you don’t see why, and why your explanation is incredibly simplistic and insufficient as an explanation of consciousness, you may not fully realise or understand the problem.

    I don’t believe in life after death etc. and I believe consciousness is indeed manifested somewhere in the brain (and tied to those electrical impulses in some way), yet find your explanation utterly insufficient to address the “hard problem” of consciousness. It doesn’t explain qualia, or subjective experience.

    Now obviously we do seem to have proved that consciousness is somehow related to such electrical impulses and other processes in the brain… but to say that we even begin to understand how actual subjective conscious experience arises from this is simply not true.

    For starters: your logical steps from brain uses electricity -> consciousness is in the brain -> therefore consciousness is in the electrical impulses is a non-sequitur.

    To illustrate: CPUs are made up of logic gates that utilise electricity to perform many operations. We know mathematical calculations are done in the CPU. Therefore mathematics is in the logic gates. Does that sound right to you? Is that in any way a satisfactory explanation of what maths is, or where mathemarical concepts exists or how marhs came to be? Does maths only exist in electrical logic gates?

    Doesn’t seem at all right does it? Yet that’s precisely the same leap of logic you just used.

    Now before you reply with “ah, but that’s totally different” carefully examine why you think it’s different for consciousness…

    In addition, there are more than just electrical impulses going on in the brain. Why do you choose electrical or only electrical? Do you think all electrical systems are conscious? What about a computer? What about your house electrical system? Do you draw a distinction? If so, where is the distinction? Can you accurately describe what exactly about certain electrical systems and not others gives rise to direct subjective experience and qualia? What is the precise mechanism that leads to electrons providing a conscious subjective experience? Would a thinking simulation of a brain experience the same qualia?

    If you really can’t see what I’m getting at with any of this, perhaps you might be a philosophical zombie… not actually conscious yourself. Just a chemical computer firing some impulses that perfectly simulates a conscious entity, just like an AI but in meat form. Carefully consider: how do you personally know if this is or isn’t true?




  • In this thread: people who don’t understand what power is.

    Power isn’t something that is “pushed” into a device by a charger. Power is the rate at which a device uses energy. Power is “consumed” by the device, and the wattage rating on the charger is a simply how much it can supply, which is determined by how much current it can handle at its output voltage. A device only draws the power it needs to operate, and this may go up or down depending on what it’s doing, e.g. whether your screen is on or off.

    As long as the voltage is correct, you could hook your phone up to a 1000W power supply and it will be absolutely fine. This is why everything’s OK when you plug devices into your gaming PC with a 1000W power supply, or why you can swap out a power-hungry video card for a low-power one, and the power supply won’t fry your PC. All that extra power capability simply goes unused if it isn’t called for.

    The “pushing force” that is scaled up or down is voltage. USB chargers advertise their capabilities, or a power delivery protocol is used to negotiate voltages, so the device can choose to draw more current and thus power from the charger, as its sees fit. (If the device tries to draw too much, a poorly-designed charger may fail, and in turn this could expose the device to inappropriate voltages and currents being passed on, damaging both devices. Well designed chargers have protections to prevent this, even in the event of failure. Cheap crappy chargers often don’t.)



  • > Have you been to an IMAX? Every seat can see the whole screen.

    I don’t understand this comment… Why do you think I’m implying that people can’t see the whole screen from every seat? I don’t see how it’s related to what I said.

    I was simply jokingly observing the irony of sitting at the back to reduce the size of the screen in your field of vision because you have difficulties observing a wide field – a problem that is exacerbated by going to a larger screen in the first place.
