Why would I refuse to?
Sure, science is not really very connected to morality.
Although it
is a valuable resource for investigating reality, and as such it is unavoidably invaluable for morality and ethics as well, since those (at their best, anyway) require reliable information about the likely results of various actions and neglects.
But that is just a part of it. Morality proper is an arising property of sentience, as well as a discipline of applied reason.
Then notice that it is the same, for that is as in the is-ought problem.
Uh, I don't think that is at all true. On the contrary; the very reason for being of morality is to
be the bridge that such an impasse presents.
Maybe you can explain why you disagree?
I am an anti-realist when it comes to meta-ethics and you can't solve that with any philosophical system. Biology in humans causes anti-realism as result for meta-ethics and there is no objective truth, proof, evidence or what not possible as long as we remain humans(a case of conditional knowledge).
I truly disagree here. Moral truth may be challenging in some respects, but that is only because we are subject to the limitations of our own reasoning ability and other personal circunstances.
Granted, that is no small complication.
Nonetheless, morality also is and must be informed by objective facts, if it is to be anything other than a form of fiction. And if we go
there, its very existence is nothing but an arbitrary, unsustainable action. That could only make any sense when joined with rather extreme statements about the very existence of reality.
Nothing has changed since this:
"Man is the measure of all things: of the things that are, that they are, of the things that are not, that they are not." - Protagoras
Not at all, if we are still talking about morality and ethics. And that because those disciplines need awareness of many objective facts on fields such as nutrition, medicine, ecology, and economics.
