- We think thoughts that are about Fness.
- There is no good naturalistic explanation of how our F-thoughts manage to make claims about reality.
- The best explanation of how our thoughts succeed in being about Fness, of how our F-thoughts have intentionality, involves God.
- metaphysical possibility
- proper function
- objectively beautiful
The point in this line of argument isn't that these properties depend on God. Rather, our grasp of these properties either is given to us by God, directly or not.
A related argument schema is to ask for the explanation of how we know F-facts.
