Full Idea
My main objection to Fine's notion of grounding as fundamental is that it violates 'purity' - that fundamental truths should involve only fundamental notions.
Gist of Idea
If you make 'grounding' fundamental, you have to mention some non-fundamental notions

A Reaction
[p.106 of Sider for 'purity'] The point here is that to define a grounding relation you have to mention the 'higher' levels of the relationship (as in a 'city' being grounded in physical stuff), which doesn't seem fundamental enough.
