Ronan,
First it is not simply that we can never explain, it is that we cannot explain because we will have to feel what is like to be a bat in order to know
And why assume that is impossible? The argument is fundamentally flawed because of an assumption of a “never” condition placed on an unknown future.
If science is able to reverse engineer the mechanism of consciousness then that allows the potential possibility of creating the condition that would permit experiencing and knowing what it would be like to be a bat.
and we will never know because first of all unconsciousness is a assumption and secondly causation is also an assumption (only thing we have is correlation)
There is the flaw again of attempting to predict the future.
I don’t see any relevance to the issue of unconsciousness here. This appears to an error in confusing different terminology. Being unconscious is akin to being asleep, while being conscious is akin to being awake and aware. The issue here is consciousness, i.e. what it means to be “I”, and how is it possible for me to be self-aware.
We make assumptions all the time, some are fundamental to any meaningful progress and we generally call these axioms. E.g. existence exists, reality exists, there is cause and effect. These are universally accepted starting points that provide a frame of reference for future discussion.
Assumptions are fine if they are appropriately substantiated.
Nagel does not talk about now and in fact in his paper he ask us to imagine if we could know everything about physical reality and what a bat is, we would still not know what is the feeling of the bat because in order to know we have to feel it
Please read his article first!
It is a flawed argument since he is indeed attempting to limit what science can do in the future. He is making unsubstantiated assumptions based on his opinion on what consciousness is and then drawing flawed conclusions.
How can you explain consciousness by something that is inside consciousness ?
You have yet to make a meaningful case that consciousness is inside another consciousness.
There is no reason yet to conclude that consciousness is not a physical phenomenon and hence not able to be explained by science.
Moreover (apart from the last question) remember that the content of your consciousness can be a dream
so it is simply not possible to explain because you will always have the doubt!
This is irrelevant to a scientific study of the mechanism of consciousness.
no, I said consciousness is god,
individual consciousness (as one part of the content of consciousness) is caused by consciousness
Whatever variation you choose is fine, the issue is you have introduced a conclusion, that a god is involved that has no basis.
