That science hasn't positively "established the non-existence of the soul" doesn't mean that there is an empirical or rational justification for the metaphysical belief in its existence. In fact, substance dualism is extremely implausible for several philosophical and scientific reasons.JamesOfSeattle wrote: ↑June 27th, 2018, 2:14 am …My final conclusion, then, about the substantial Soul is that it explains nothing and guarantees nothing. Its successive thoughts are the only intelligible and verifiable things about it, and definitely to ascertain the correlations of these with brain-processes is as much as psychology can empirically do. From the metaphysical point of view, it is true that one may claim that the correlations have a rational ground; and if the word Soul could be taken to mean merely some such vague problematic ground, it would be unobjectionable. But the trouble is that it professes to give the ground in positive terms of a very dubiously credible sort. I therefore feel entirely free to discard the word Soul from the rest of this book. If I ever use it, it will be in the vaguest and most popular way. The reader who finds any comfort in the idea of the Soul, is, however, perfectly free to continue to believe in it; for our reasonings have not established the non-existence of the Soul; they have only proved its superfluity for scientific purposes."This is concise, simple and fair, and it reads like it was written yesterday instead of a century ago. It leads to the obvious conclusion that the answer is unknown.

The great Australian philosopher (and reductive physicalist) David Armstrong writes the following:
"There is no certainty in philosophy. No philosopher can know that his or her arguments are true."
(Armstrong, D. M. A World of States of Affairs. Cambridge: Cambridge University Press, 1997. p. xi)
"One moral that I draw is that in the fields of philosophy and religion there is no knowledge. We can only know what our beliefs are."
(Armstrong, D. M. "A Naturalist Program: Epistemology and Ontology." Proceedings and Addresses of the American Philosophical Association 73.2 (November 1999): 77-89. p. 82)
Beliefs that fall short of knowledge can still be justified or unjustified, rational/reasonable or irrational/unreasonable, probable or improbable, plausible or implausible.

It does serve me, and I think, all men, to believe we have a will, and that our actions therefore have some meaning.Materialists surely don't "negate( ) their very existence". As I already mentioned, materialism is consistent with the negation of determinism, and there is disagreement among the determinists over whether compatibilism or incompatibilism is true. For example, Daniel Dennett is a staunch materialist and determinist, but he rejects incompatibilism.
Why would anyone voluntarily assent to something unproven, if doing so negates their very existence? I'm not trying to attack anyone here, but the only reason I can see is a cop out. Perhaps they are too lazy or frightened to take on life, and would prefer to think of themselves as being pushed along by events at all times, rather than having some say in outcomes (and thereby some accountability for outcomes).
I'm assuming above that most people would not be 'compatibalists' and be able to reconcile a free will with materialism and/or determinism. However, I think it would be interesting to see someone try to support that position.
If you think that you directly experience the falsity of determinism and the existence of totally undetermined, libertarian free will, you are wrong insofar as this is a theoretical interpretation of your self-experience and your intentional actions that may well be false. This sort of free will ("superfree will") may well be (and arguably is) a subjective illusion.
How do you know that when you do x at time t, you could have done otherwise at t?
