explain what logic can and cannot do. In other words, what kinds of questions and logic are not decided by logical analysis
Is abortion moral?
Is there a God?
What are the ethics of polygamy?
the ethics of polygamy is to tell if someone is telling the true.
These are questions that logical analysis cannot answer.
Btw -- check the definition of polygamy.
the definition of polygamy is having more than one spouse, especially wife, at one time.
Now back to your original question.

I think that you are right this a question that a logic cannot answer.
