Well, there is no empirical evidence that consciousness comes from the brain, only that it seems to come from the brain. We mustn't conflate correlation with causation.Orenholt wrote:Ok I can accept that. BUT why would we disregard empirical evidence that consciousness comes from the brain? I know it's just a guess but isn't it a logical one given what information we have?sue hindmarsh wrote:Orenholt wrote:
It’s not that the perception of a thing is necessarily false (or true) it is that perceptions are by their very nature untrustworthy. You can only build a tentative reality from them. For example, we look at the fossil evidence and extrapolate from it that dinosaurs existed. But we can’t be sure that they ever did exist, we can just accept that they might have. This doesn’t make dinosaurs any less real, for as an example their existence and every other things existence relies on that same reasoning. And that’s fine, because for the most part it is practical for us to see things this way.
For science and ordinary day to day life that way of looking at things can work fine, but when it comes to philosophy such guessing isn’t enough. Ultimate reality is what matters, so certainty is what one is after – and that can only be found through logic.
David Quinn once gave another example, saying something along the lines of: If our car does not start, and we rework the spark plugs which seemed fine but might not have been, and afterward the car then starts, we assume that the spark plugs were indeed not fine and therefore the cause of the car's failure to start. But do we really know this? What if they were fine all along, and that, in our messing with them, we unknowingly bumped some other connection back into its proper place, and that was what allowed the car to start again? We can never be exactly sure of what the particular cause was.
To be sure, we can narrow them down through a process of elimination and pick the most likely one. But it is just that -- the most likely one -- and nothing more. It is never 100% certain. Likewise with consciousness and the brain. Likewise with all empirical matters of the senses. You yourself just noted that it's just a guess. In philosophy, a guess does not cut it. If you want the true prizes of philosophy, you're going to have to go on quite a long journey, and one of its first steps is beginning to think in terms of what is ultimately real. That is, leave the guessing games for your scientific interests, not your philosophical quest.
But really, I'm now the 4th (5th?) person on this forum to personally point this out to you, and it's found many other places as well, and of course, in your own mind. Please, less posting, more thinking. Don't get me wrong -- conversation with others is important, but without contemplation (conversation with your self), it is useless, and will at best make you a self-assured parrot, but will most likely leave you feeling uncertain and even stupid. I don't think this conversation has been pointless, as it's always worth the effort to wake another person up, but Dennis Mahar had a point in that these issues cannot be forced.
