I noticed that, most of the time, when atheists attack the concept of God, they mean the divine attributes in univocal terms. For example, JL Mackie attacks the concept of God by using his logical POE,
(1) God is all-powerful and all-good
(2) Evil exists
(3) Then either He is all-powerful but not all-good or He is all-good but not all-powerful
(C) Therefore, God cannot exist
Mackie assumed "all-good" to be morally good in the same sense as us humans, but in a higher degree. However, Thomists deny univocal terms regarding God, instead Thomists use analogous terms. Also, Thomists deny that God is a moral agent. Hence, the logical POE loses a lot of its force. Indeed, if one uses univocal terms regarding God then one will get into trouble, especially when it comes to Divine Simplicity. I have not read Martin's "Impossibility of God" but I read Paul Copan's review of the book. He mentions that a lot of the "disproofs" are not that good. Maybe some day I will read it.
