Lawrence Krauss vs. John Lennox on science and faith
by J.W. Wartick
I’ve been catching up on my podcasts and I recently listened to a dialogue between an atheist, Lawrence Krauss, and a theist, John Lennox on questions about science and faith. It was on the Unbelievable? program (something I strongly suggest you listen to weekly) [listen here]. Thus, it was less a debate than it was a moderated discussion. Here, I’ll only focus on a couple questions that came up in their dialogue.
How and Why
According to Lawrence Krauss, science cannot answer “Why” questions but only “how” questions. Lennox brought up the example of a Ford motor car sitting on a driveway [I added this last bit for clarity]. He argued that one can explain the “how” it got there but there still remains the question of “why” it was made. Thus, the “why” questions remain “real” questions whether or not science is capable of investigating them. Interestingly, Krauss took a different tact than I expected in his

rebuttal: he argued that the “why” question (at least in the Lennox case) is reducible to a “how” question. That is, one could explain how Henry Ford designed it, had it built, and then someone bought it and drove it to where it is sitting.
But of course redefining terms does little to address the actual questions at hand. Lennox was keen to show that questions about “why” are indeed meaningful. It seems that Krauss’ only response is to either say “no they’re not” or redefine actual “why” questions into “how” questions and argue there still are no “why” questions. The move is not very subtle, nor is it successful.
Purpose in the Universe?
Krauss made several comments regarding purpose in the universe. First, he seemed to suggest that in order to assert the universe has purpose, one must know what that purpose is. Second, he argued that the universe is indeed quite wasteful if it were intelligent designed with purpose. Third–in response to Lennox’s statement that Krauss and other cosmologists admit that for life to exist there would have had to be several generations of stars (to produce enough carbon for carbon-based life)–he alleged that there could be all sorts of other life forms we don’t know about. I’ll address these each briefly in turn…
