Because of your position against universals, you might be interested in viewing and commenting on this other thread which is actively debating Nominalism v Realism: If a Tree Falls in the Forest...the indivisible link between consciousness and existence.. You and I are polar opposites in that debate. LOL!
Concerning fideism, the Lurkers might be interested in reading more about it over here on Wikipedia. Again, you and I are polar opposites in the debate. But that is good to know!
I am not opposed to universals, per se. What I claim is that they have no existence independent of God. I do not say "independent of some consciousness" as the referenced thread does (which is just a rewording of George Berkeley's [1685-1753] contention). What is the "essence" of the number 7? It is a truth that God knows, and which I, in his image, can know. Nothing more--but also nothing less. Imagine: that we can know things that are in the mind of God. That have been, that always shall be. This is a thing ignored by fideists: because of the gift of reason, we are in Eternity...even now.
