When I first saw that headline, I was a little bit concerned, because too frequently I've seen people pretend that the existence of God is subject to scientific, ie, empirical proof. That's a mistake because whatever God is, He's clearly outside the bounds of scientific investigation. Thankfully, Mr. Bollore appears to understand this distinction very well, and I appreciate his attention to detail. I think I'd be very interested to read this book once it's translated.

Great article, thanks for doing this interview. I'm looking forward to seeing a translation of this book!

What Bolloré had to say about epistemology is critical to understanding why you can't perform a purely deductive proof regarding the existence of God -- namely, that you can't perform a purely deductive proof about anything in reality! Deductive logic only operates on what you have ascertained about reality, but knowledge is achieved through inductive reasoning. Everyone is doing this all the time, and it is the only means the natural sciences have for "proving" anything. The best anyone can do is "inference to the best explanation" (IBE), but notice how that idea already has human judgment embedded in it: what is "best"? Reasonable people can and do disagree.

This is why, as Bolloré says, you have to look for converging lines of evidence, or "consilience," as the best indicator of what is likely the case. Hence, St. JPII was justified in saying during his October 22, 1996 address: "Today... new

findings lead us toward the recognition of evolution as more than an hypothesis. [...] The convergence in the results of... independent studies — which was neither planned nor sought — constitutes in itself a significant argument in favor of the theory." If all we had was a fossil record, that's one thing. But that the biological evolution of species one from another explains so many different things about the world indicates its facticity. Still, humans are left to make the judgement.

This caught my attention towards the end: "I must admit that many ecclesiastics have been very unhappy with the book. Usually, they say that God does not require proof, and if there were proof of the existence of God it would reduce the merit of faith." Without knowing the details of what said "ecclesiastics" mean by such statements, my first response is, "These dudes need to go read Aquinas."

Divine revelation is the matter of faith, not what natural reason can grasp about reality. I fear that such opinions stem from the abandonment of good philosophy in seminary training after Vatican II. On the other hand, it is true that inference to a creator God is of a different order of knowledge than me knocking on the table in front of me, or accepting that electrons exist. If this is all they mean by such statements, fine. God is not a material object, so he cannot be the subject of empirical scientific study. But this does not discount paying attention to "where the science points," especially when we're asking the question of why the scientific study of reality can be done in the first place.
