But all we have for "truth" to correspond to is our functional experience. But functional experience creates value assessment, and value assessments lead to moral dilemmas that require more truth than functionality can provide.
Moral dilemmas are problems for the individual brain, using our evolved moral instincts ─ child nurture and protection, dislike of the one who harms, like of fairness and reciprocity, respect for authority, loyalty to the group, and a sense of self-worth through self-denial ─ and our evolved moral faculties, empathy and conscience, and the morals we acquire by our upbringing, culture, education and experience, which govern social interactions and behavior for occasions. We know about these matters from reasoned enquiry and observation. We also observe that there are no absolute moral statements ─ against the background I've just mentioned, "good" means beneficial or pleasing to me and mine and the causes I support, and bad means detrimental or displeasing likewise.
That is also it's abject failure.
We'll have to disagree on that. I'd say reasoned enquiry, of which scientific method is an example, has been and is an outstanding success. The statements of science, for example, and the resulting technologies, have been of enormous benefit to humans in terms of convenience and health.
Science cannot address the problem of value assessment or moral imperative
But as I mentioned, reasoned enquiry can. Scientific method is only one aspect of reasoned enquiry. There's also historical method, mathematical method, and the rather flabby history of psychological research is being stiffened at last by hard medical brain research.
not only does science neither seek nor find truth, It gives us the powerful illusions that it does
BUT there are no absolute truths. Truth is the best opinion of the best relevant brains at any time. It was once true that the earth was flat and the heavenly bodies went round it, but now its not; that light propagated in the lumeniferous ether, but now it's not; that the earth's crust was uniform and rigid, but now it's now.
And in the moral sphere, as the bible makes clear, it was once morally correct to conduct invasive war, to massacre populations, to trade in slaves, to offer human sacrifice, to treat women as property, to practice murderous religious intolerance; and now, at least where I live, it's not.
I think science is the study of physical function, that results in increasing our physical functionality. But beyond that, it's mostly useless.
Science is that part of reasoned enquiry that explores, describes and seeks to explain nature. Perhaps one day it will stop the election of populist leaders like Trump, Johnson, Bolsonaro, Orbán and more; but that goes back to our tribal origins and the instincts that resulted.
And what is beyond functionality is still very important. Maybe even more important than functionality is. Because determining whether "X" is a weapon or a tool is at least as important as having "X" in the first place.
We're not far apart. But I think reasoned enquiry will continue to do those things that are outside of science's remit.
