Are there "elements of" which don't contain value judgements?

That strikes me as a question for dictionary writers. If we agree that Newton's laws of motion constitute such an element, then clearly, there are such elements that do not not contain value judgements.

Is Alice's preference for cabernet part of Alice's world model?

iff she perceives that preference.

If Alice's preferences are part of Alice's world model, then Alice's world model is part of Alice's world model as well.

I'm not sure this follows by logical necessity, but how is this unusual? When I mention Newton's laws, am I not implicitly aware that I have this world model? Does my world model, therefore, not include some description of my world model? How is this relevant?
