2391 | Can we be aware but not conscious? [Chalmers] |
Full Idea: Consciousness is always accompanied by awareness, but awareness as I have described it need not be accompanied by consciousness. | |
From: David J.Chalmers (The Conscious Mind [1996], 1.1.5) | |
A reaction: One should consult Chalmers, but he is stretching the English word 'awareness' rather far. This road leads to saying that thermostats are 'aware', and information is aware of its content, which is probably very wrong indeed. Compare Idea 2415. |
2412 | Can we explain behaviour without consciousness? [Chalmers] |
Full Idea: However the metaphysics of causation turns out, it seems relatively straightforward that a physical explanation of behaviour can be given that neither appeals to nor implies the existence of consciousness. | |
From: David J.Chalmers (The Conscious Mind [1996], 2.5.2) | |
A reaction: Chalmers needs this to support his idea that zombies are possible, but it strikes me as implausible. I find it inconceivable that our behaviour would be unchanged if we retained 'awareness' but lost consciousness. Try visiting an art gallery. |
2386 | Hard Problem: why brains experience things [Chalmers] |
Full Idea: The Hard Problem is: why is all this brain processing accompanied by an experienced inner life? | |
From: David J.Chalmers (The Conscious Mind [1996], Intro) | |
A reaction: The word 'accompanied' is interesting. A very epiphenomenal word! The answer to this neo-dualist question may be: if you do enough complex representational brain processing at high speed, it adds up to some which we call 'experience'. |
2416 | What turns awareness into consciousness? [Chalmers] |
Full Idea: Given the necessity of awareness, any candidate for an underlying law will have the form "Awareness plus something gives rise to consciousness" (…but simplicity suggests leaving out the 'something'). | |
From: David J.Chalmers (The Conscious Mind [1996], 3.6.5) | |
A reaction: You can't leave out the 'something' if you think awareness without consciousness is possible. The phenomenon of blindsight suggests that a whole extra brain area must come into play to produce the consciousness. It may not have a distinct ontology. |
2423 | Going down the scale, where would consciousness vanish? [Chalmers] |
Full Idea: Moving down the scale from lizards to slugs, there doesn't seem much reason to suppose that phenomenology should wink out while a reasonably complex perceptual psychology persists….and if you move on down to thermostats, where would it wink out? | |
From: David J.Chalmers (The Conscious Mind [1996], 3.8.4) | |
A reaction: This doesn't seem much of an argument, particularly if its conclusion is that there is phenomenology in thermostats. When day changes into night, where does it 'wink out'? Are we to conclude that night doesn't exist, or that day doesn't exist? |
2403 | Nothing in physics even suggests consciousness [Chalmers] |
Full Idea: Even if we knew every last detail about the physics of the universe, that information would not lead us to postulate the existence of conscious experience. | |
From: David J.Chalmers (The Conscious Mind [1996], 2.3.1.3) | |
A reaction: I find this a very strange claim. Given that the biggest gap in our physical knowledge is that concerning the brain and consciousness, Chalmer is no position to say this. Why shouldn't a physical revelation suddenly make consciousness inevitable? |
2400 | Is intentionality just causal connections? [Chalmers] |
Full Idea: Intentional properties should be analyzable in terms of causal connections to behaviour and the environment….so there is no separate ontological problem of intentionality. | |
From: David J.Chalmers (The Conscious Mind [1996], 1.2.5) | |
A reaction: There could only be no ontological problem if intentional states were purely physical. Everything is made of something (I presume). |
2419 | Why should qualia fade during silicon replacement? [Chalmers] |
Full Idea: If parts of the brain are gradually replaced, perhaps by silicon chips, ...the most reasonable hypothesis is that qualia do not fade at all. | |
From: David J.Chalmers (The Conscious Mind [1996], 3.7.3) | |
A reaction: As it stands this could either assert dualism or functionalism. Personally I think the most reasonable hypothesis is that qualia would fade. Chalmers needs more imagination (or less?). What is it like to experience Alzheimer's Disease? |
2389 | Sometimes we don't notice our pains [Chalmers] |
Full Idea: What of the fact that we speak of pains that last for a day, even though there are times that they are not conscious? | |
From: David J.Chalmers (The Conscious Mind [1996], 1.1.3) | |
A reaction: This is hardly proof that there are non-conscious pains. Otherwise we might say we have a pain even after it has left us for good (because it might return), which seems daft. Not a crucial issue. The word 'pain' has two uses… |
2402 | It seems possible to invert qualia [Chalmers] |
Full Idea: It seems entirely coherent that experiences could be inverted while physical structure is duplicated exactly. | |
From: David J.Chalmers (The Conscious Mind [1996], 2.3.1.2) | |
A reaction: Strange how what seems 'entirely coherent' to a leading philosopher strikes me as totally incoherent. I would have thought it was only coherent to a dualist. I don't believe God makes the physics on Thursday, and adds experiences on Friday. |
2415 | In blindsight both qualia and intentionality are missing [Chalmers] |
Full Idea: In blindsight, the information does not qualify as directly available for global control, and subjects are not truly aware of the information. The lack of experience corresponds directly to a lack of awareness. | |
From: David J.Chalmers (The Conscious Mind [1996], 3.6.3) | |
A reaction: Blindsight patients give correct answers about objects in their visual field, and you need 'global control' to speak the truth, even if you lack confidence in what you are saying. Philosophers should not be frightened of blindsight. Cf Idea 2391. |
