Re: Attention: a key to understanding consciousness?

The focus of our attention is often suddenly changed as the result of a sensory input – hearing a familiar name in a conversation we weren’t listening to, maybe, or somebody waving at us, or a stab of pain from a sore toe… David Eagleman (in “Livewired”) explains that this occurs when the input is i...

Re: Free Will

What would make us think that "truth" and "algorithm" had anything to do with one another? "That sentence contains exactly 20 vowels." How would you check the truth of that claim? Why wouldn't you call it an algorithm? Well, in order to reply, you found you couldn't use an algorithm. :shock: Instea...

Re: Free Will

I'm talking about the "Multiverse Interpretation" of standard quantum theory, which is something quite different, which it sounds as if you are not aware of. I I see. I'll have to find out about that. I do know the Multiverse Hypothesis, of course; and I know of standard quantum theory. I had not h...

Re: Free Will

For a Determinist, "the will" has to be no more than a very odd way we describe a physical step in an inevitably physical chain of causes-and-effects That word "chain" implies a very dated version of determinism - it's a straw man version. Even apart from quantum uncertainty, the world is nothing l...

Re: Free Will

The evidence for quantum theory is as strong as for any theory known to science. Quantum Theory is not the Multiverse Hypothesis. They're two distinct postulates, and the latter is 100% speculative, by definition. That's all very interesting, but I'm not talking about the "Multiverse Hypothesis"! I...

Re: Free Will

On the other hand, if a mental state is neither instantaneously self-determined nor a product of prior physical/mental states, it cannot have the character of a will. This, again, does not at all seem obvious. Why can't "will" be explained in terms like, "Will is what 'the I' chooses to make out of...

Re: Free Will

I am referring to a specific and reputable viewpoint in quantum physics. It's only reputable among those who have not realized the logical and mathematical error in their postulate. I have not seen any of them provide a solution to this obvious problem. So it looks like a rapidly growing set of fut...

Re: Free Will

"everything that can happen, does happen". But there's a very fundamental mathematical error bedded in this very idea. It requires that "things that can happen" is a finite set, and yet that the Multiverses are infinite. Put those things together, and you have to believe that not only does "everyth...

Re: Free Will

Determinism has to hold that the will is strictly a product of prior forces. A belief in free will allows that its not. This is a key point. The question is, does free will require the ability to choose the state of one’s mind at the instant that one is doing the choosing? If it does, then that is ...

Re: Free Will

The first thing we need to know about the Multiverse Hypothesis is that it's a "hypothesis," an imaginary model, not an empirical reality, of course. Worse still, if we understand the word "universe," then we also realize that if anything empirical were ever found to support the idea, it would, by ...

Re: Free Will

That's because "prediction," as a word, is a description of what humans can or cannot know. Determinism, by contrast, is presented as a statement about what is actually true, whether humans know it or not. I'm trying to make a further distinction: whether or not there is an algorithm by which the t...

Re: Free Will

Well, I wouldn't be worried about that at all. I think it's obvious that "predictability with (absolute) certainty is not possible epistemologically. But "predetermined" does mean "predictable with absolute certainty in principle " if not in fact. In other words, if Determinism is true, then in the...
