The length of this post might suggest otherwise, but I’m not going to reproduce my book, Philosophy after Christ, here but Maverick Philosopher and friend William “Bill” Vallicella (the subject of several posts, e.g., here, here, and here) recently posted essays on theistic argumentation, and I thought it deserved a response.
Preamble: if the God of the Bible, who created human beings in his image to know and love him and to know, value, and rule the rest of creation under him (hereafter, “God”), exists, then we know one way that the conditions of intelligible predication (IP) can be met. The preceding sentence includes key aspects of the Christian worldview (CW)—the Theos-anthropos-kosmos relationship—expressed on the pages of the Bible.
If no alternative explanation for IP is possible, then Biblical theism is necessarily true (which is what the CW predicts).
Knowing whether IP has conditions and that they’re met is a “big deal.” It underlies everything one does, not something one can take for granted. And yet virtually every thinker, yea, every philosopher, takes the satisfaction of those conditions, which must obtain, for granted. This taking is arbitrary, and being arbitrary does not comport with philosophizing.
If no worldview other than the Christian (CW) can account for IP, if (as I now hold) an alternative to the CW when it comes to accounting for IP cannot even be conceived, then to hold out for an alternative, as though doing so were an expression of rational exigency (“demandingness”)—that to reserve judgment somehow accords with epistemic duty—models only dogmatic stubbornness, not tolerant liberality.
Referring to the transcendental argument (TA) laid out in Chapter 13 of my book, I will call Bill’s bluff. After reading it, he may still say, “Well, Tony, I remain unconvinced”; if my argument goes through, however, then I will interpret such a response as an expression of his commitment to what he calls his “characteristic thesis” (CT). To paraphrase Brand Blanshard, it wrong to leap to a conclusion that argument’s premises don’t entail, but it is no less wrong to fail to draw an inference that they do entail.
