So, Jerry Coyne is asking for responses to a position of Polkinhorne’s. The position is this:
His two arguments are these:
* The universe can be comprehended by the rational faculties of humans, and its workings appear to adhere to laws of physics.
* Much of our understanding of the universe is expressed through mathematics, which is “unreasonably effective” in encapsulating what we discover about nature.
Ergo Jesus.
(Coyne, BTW, would do well to lose the dismissive “Ergo Jesus” at the end. It’s annoying enough when it might actually be the case that they’re using the argument to get to the Christian God, but since he uses it even when they aren’t it’s really annoying.)
Coyne quotes Polkinghorne in some detail:
“. . . why is science possible at all in the deep way that has proved to be the case?” p. 71
“A distinguished nuclear physicist, Eugene Wigner, once asked, ‘Why is mathematics so unreasonably effective?’ Those seeking an understanding as complete as possible must ask what it could be that that links together the reason within (mathematical thinking) and the reason without (the structure of the physical world) in this remarkable way? The universe has not only proved to be astonishingly rationally beautiful, affording scientists the reward of wonder for all the labours of their research. Why are we so lucky?
It would surely be intolerably intellectually lazy not to seek to pursue this question. Yet science itself will not provide its answer, for it is simply content to exploit the opportunities that these wonderful gifts afford us, without being in a position to explain their origin. Theology, however, can step into the breach. Science has disclosed to us a world which, in its rational transparency and beauty, is shot through with signs of mind, and religious belief suggests that it is indeed the Mind of the Creator that lies behind the wonderful order of the universe. (p. 73)
Now, I’m not going to answer this or respond to it, favourably or unfavourably. All I’m going to do is examine and clarify the question, and the issues around it. At the end of this, my only hope is that you’ll understand what is at stake here and what are the implications and the issues that each side of the argument have to address. Then, I’d ask you to read Coyne’s initial responses and the ones in the comments to see if they really go after the question that is being asked here.
Polkinghorne’s argument is basically that the universe we have seems to be, for the most part, rationally infused. By taking a rational and even intentional approach, we have had great successes. It really seems that the laws of physics are exceedingly and excessively rational and mathematical, in such a way that science and understanding can proceed under what you’d call almost ideal conditions. Thus, we can form incredibly detailed and generalized models that just work, with little ad hoc corrections and manuevering. The universe, then, seems ideally rationaly understandable by the best tools of logic and reason, including mathematics. But there’s no reason to think that this is just the natural state of affairs; we could certainly be in a world where fewer things are generalizable and where a grand Theory of Everything would be automatically dismissed as a pipedream as opposed to a Holy Grail. The universe seems intentional and rational, and Polkinghorne’s argument is that this then reflects a rational, intentional and intellectual mind. That mind, then, is God’s mind.
Now, there are numerous potential pitfalls along the way. The first challenge is whether or not this universe really is that ideally rational. While our scientific models look pretty, in practice you always have to slip a lot more ad hoc reasoning into them, and sometimes even contort the mathematics slightly to get them to work out in the world. For the argument to work, it must be the case that reality is ideally rational, not our best academicized models of it. This leads to the second objection, which is that maybe our laws are not as reflective of it all as we’d like. Maybe, like Newton’s equations, they only work locally, and break down elsewhere in the universe. Yes, we have some cosmological results that suggest otherwise, but those have enough issues — dark matter, for example — that we can’t be certain that our generalizations really do hold … or that we can really generalize that far. Now, most scientists will probably defend the rationality of the laws and their generalizability, but that doesn’t leave them out in the cold when it comes to criticism. They can ask if it really is the case that a rationally ideal universe must be generated by a rational mind, or if this could just happen on its own. Maybe, in fact, this is the normal way of things; universes tend towards greater regularity unless they can’t. And the last desperate gasp is to deny that if it needs a mind that doesn’t make it God, but if you have a rational mind that created the universe you’re well, pretty much there, so it would be a desperate grasp at some counter, but not a very strong rebuttal.
Note that none of these counters, though, are damning. The argument is essentially this:
1) An ideally rational universe requires a rational mind to have structured it that way.
2) This is an ideally rational universe.
C) This universe requires a rational mind to structure it that way.
In order to oppose it, then, you have to attack either 1) or 2). Anything else is sophistry that brings in other arguments or disputes to dodge the key argument being made here. As I said, both premises can be challenged, but it isn’t clear that they’re false. Which means, then, that the argument — in my not-so-humble (and Not-So-Casual) opinion — is interesting and worth considering, but it needs more work to actually prove what it is trying to prove. There are, as far as I can see, no quick rebuttals, but this argument isn’t a killer one either.
Which, really, is where the fun begins for philosophers and theologians.
And so I face the final curtain …
February 28, 2012The latest Not-So-Casual Commentary is up.
I’ve suddenly gotten really busy and had to run around with a lot of things, so my posting schedule has been blown. But I hope to get back up to speed soon.
