I agree it is a fair question.
All attempts to know

I think that a concept of "should" is implied by the task of "recommending"(Ethical Philosophy's defined task).
I was operating under the linguistic assumption that if someone "should" do something, that means the same thing as being "obligated" to do that thing.
I grant you that I am making an
assumption in thinking that there exists a right or wrong conduct, but this is
the assumption used to define the sphere of Ethical Philosophy.
Denying that such a thing as right or wrong conduct exist is also a perfectly valid
assumption, doing so basically amounts to saying "I don't believe that the subject of study in ethical philosophy exists".
So also, in a discussion of the "nature of God",
a perfectly valid assumption is "I believe God's nature is non-existence."
It doesn't offer much in terms of advancing a discussion, but if that is God's nature then there isn't much to discuss anyhow.
