I think this one is something of a sticking point. Our saying that mind depends upon brains seems true because we observe that a complete loss of consciousness follows death and destruction of the body (and the death of the brain). And yet all we are concluding is that evidence for what we call consciousness is no longer apparent...
True. I'm going with the simplest assumption--that things are as they appear to be. That is not always the case, but it is usually the case. In fact, we often live as if our lives depended on that simple assumption, and I think that they usually do.
Well, I think that we can say a lot more than that about the nature of consciousness. Consciousness also seems to depend on memory. There is a discrepancy between what we perceive in the moment and what we remember just having seen. I wonder if it is even possible to have consciousness without memory. And we do know that memory is very much dependent on the physical condition of the brain. There are so many things that can go wrong with it and that can be traced to very specific types and locations of brain lesions....Consciousness is simply an awareness of one’s existence, an ability to think and perceive...
Yes, analogy is the foundation of human cognition. We understand everything by analogy with past experiences, beginning with bodily sensations. That is what we mean when we talk about an "embodied mind".We identify other minds by the actions of the corporeal forms that contain them. We say ‘I am conscious and I see others who act similar to me, therefore they too are conscious’...
You are missing my point here. We assume death because we experience loss of consciousness all the time, and we know that brain trauma causes it. We can also associate mental function very closely with brain activity. Hence, it is reasonable to assume the absence of mental function with loss of brain activity. Every time we go to sleep, we get closer to what death is like, which is to say that it isn't like anything at all. It is just a gap in our awareness. Death is the ultimate gap--a mirror image of what we experienced before birth....And so we assume of a dead body that its mind is dead because minds, we say, are just brains and the brain is now dead. But if mind is not corporeal then it doesn’t follow that consciousness is absent...
Yet all human beings, alive or dead are entirely the same in a certain respect: we are carbon-based substances. So it seems correct to say:
We are more than just carbon, and I do not accept this syllogism. Consciousness is not of the same category as the physical. It is a condition that allows our type of physical being to survive and reproduce.That which exists is physical.
Consciousness exists.
Consciousness is physical.
I'll repeat what I have said before. I am not opposed to mind-body dualism, but I consider it asymmetric. Physical things can exist independently of consciousness, but not vice versa. Consciousness is an effect--an emergent phenomenon--of a physical system.This is asserting that only physical things can exist...
