Can you deduce physical facts from new moral facts? >
Why not?
Because your only sources of new facts are your senses.
You can’t infer new (to you) facts from information you already have? You can’t
just be told things? A martian,. being told that pre marital sex became less of an issue after the sixities might be able to deduce the physical fact that contraceptive technology was improved in the sixities.
I guess you could but you couldn’t be a perfect Bayesian.
Generally, when one is told something, one becomes aware of this from one’s senses, and then infers things from the physical fact that one is told.
I’m definitely not saying this right. The larger point I’m trying to make is that it makes sense to consider an agent’s physical beliefs and ignore their moral beliefs. That is a well-defined thing to do.
How can you answer questions about true moral beliefs whilst ignoring moral beliefs?
All the same comprehension of the state of the world, including how beliefs about “true morals” remain accessible. They are simply considered to be physical facts about the construction of certain agents.
That’s an answer to the question “how do you deduce moral beliefs from physical facts”,not the question in hand: “how do you deduce moral beliefs from physical beliefs”.
That’s an answer to the question “how do you deduce moral beliefs from physical facts”,not the question in hand: “how do you deduce moral beliefs from physical beliefs”.
Physical beliefs are constructed from physical facts. Just like everything else!
You can predict that (physical) human babies won’t be eaten too often. Or that a calculator will have a physical configuration displaying something that you inferred abstractly.

Where does it say that? One needs good information, but the sense can err, and hearsay can be reliable.
The sense are of course involved in acquiring second hand information, but there is still a categoreal difference between showing and telling.
In order to achieve what?
Simplicity, maybe?
A simple way of doing what?
Answering questions like “What are true beliefs? What is knowledge? How does science work?′
How can you answer questions about true moral beliefs whilst ignoring moral beliefs?
Well, that’s one of the things you can’t do whilst ignoring moral beliefs.
All the same comprehension of the state of the world, including how beliefs about “true morals” remain accessible. They are simply considered to be physical facts about the construction of certain agents.

Physical beliefs are constructed from physical facts. Just like everything else!
But the context of the discussion was what can be inferred from physical beliefs.
Also your thoughts, your reasoning, which is machinery for perceiving abstract facts, including moral facts.
How might one deduce new physical facts from new moral facts produced by abstract reasoning?
You can predict that (physical) human babies won’t be eaten too often. Or that a calculator will have a physical configuration displaying something that you inferred abstractly.
You can make those arguments in an entirely physical fashion. You don’t need the morality.
You do need the mathematical abstraction to bundle and unbundle physical facts.
You can use calculators without knowing abstract math too, but it makes sense to talk of mathematical facts independent of calculators.
But it also makes sense to talk about calculators without abstract math.
That’s all I’m saying.
I agree. But it’s probably not all that you’re saying, since this possibility doesn’t reveal problems with inferring physical facts from moral facts.
There is a mapping from physical+moral belief structures to just-physical belief structures.
Correct physical-moral deductions map to correct physical deductions.
The end physical beliefs are purely explained by the beginning physical beliefs + new physical observations.
Meaning what? Are you saying you can get oughts form ises?
No, I’m saying you can distinguish oughts from ises.
I am saying that you can move from is to is to is and never touch upon oughts.
That you can solve all is-problems while ignoring oughts.
