What do you regard as a scientific test that would falsify Determinism?
I never thought I’d find myself writing this, but I agree with everything you’ve written here!
Call the press!
And I have no answer to your question, so there’s a win for you!
Gracious. Thank you.
Now then, I know you’ll have seen this one coming. What do you regard as a scientific test that would falsify free will?
I haven't advanced Free Will as a scientific theory, but rather as one that is strongly existentially and sociologically compelling; but I did not promise to close the question so far as that. I don't think we can.
Free Will is like consciousness, reason, morality, selfhood, and a bunch of other "spiritual" realities: they're not the kinds of things that are amenable to scientific measurement, because science does not work on non-physical entities. It's not a universally-powerful methodology, just a very powerful way to deal with material problems. Put it in charge of stuff that's not physical, and its proponents can only cope by denying those realities even exist. (This is why Determinists notoriously profess skepticism about things like "selfs", "minds" (as opposed to "brains") and "morality": they're not physical properties.)
Determinism, however, is an ardently
material theory. It deals with physical cause and effect, and denies the relevance of anything beyond that. Therefore, in principle, it ought to be able to be falsified by some test.
Now, if you only believe in Determinism
as a preference, and not as a physical description of how real cause-and-effect work, you won't owe me any such explanation, of course. But if you do think it is THE truth about how things work, and an accurate scientific description of causality, then yes, you would owe some sort of test for falsification.
Got one?
I don’t want to be late for the latest dose of vitriol flung in my face by old Spheres.
I thought I’d explained to you, fairly lucidly, why my own behaviour was not evidence of free will. Please tell me where I’ve failed to do that.
I have the same old problem with Determinism. Sometimes you can't PROVE something wrong, but that doesn't make it right.
Remember the old story about Galileo? Forced by the Aristotelians and the Inquisition to recant the idea that the Earth isn't fixed, he is said to have muttered under his breath as he left, "And yet it moves."
That's probably an urban legend. But you get the point: just because you lack the present means to convince a particular audience of a point does not guarantee you aren't still right. None of us knows what the size of the universe is, and nobody can demonstrate it. But everybody also knows the universe has a size, because it's expanding. Can any of us PROVE what that size is? No. And yet it has one. Interesting.
Free-willians don't have to work to destroy all belief in Determinism. We all know that SOME elements of our past are set by others or by previous forces, without our consent. If nothing else, none of us is in charge of the circumstances of his birth, his gender, his physical potential, his eye colour, and so on. Much is settled. The whole question of free will hinges on this: is ANYTHING not simply predetermined like that?
And if there is one, or only a few, then Free-willians win the day. Determinism would then not be a comprehensive explanation of the universe. The upshot, then, is that Free-willians don't deny all causality: they deny there is ONLY strict, material causality, and maintaining that "human choice" is a causal agency in its own right.
