Famous and knowledgeable

Good week, Rabbi.
When the Maimonides says in Part One, Chapter Two of the Teaching that good and evil, obscene and pleasant, are determined by the known and not the understood, does this in itself mean that all religious and faith-based decisions are merely a product of the known?
As Pascal says, "There is nothing in the world that is right for reasons that are logical. The accepted practice (like the famous ones) determines the rightness, that it has no other meaning than that it is agreed upon and accepted. This is the secret of its authority, and the tendency to place it on its own principle is its undoing."
And David Hume also seems to me to argue the same thing because of the irrationality of values. He testifies that their root is "from emotions." The question is what does he mean by emotions and do you agree with him about this and what do you think?
I'm really sorry for the interruption and thank you very much.
