The fine-tuning argument says that if the laws of our universe had been just slightly different, intelligent life could never have existed. Some say this shows that the cosmos was carefully designed by a supreme intelligence as a home for people like us.
I have explored this question in a fictional conversation in my book, Bridging the God Gap. In this discussion, Theodore is a theist; Althea is an atheist, and Agnes is an agnostic. Obviously I do not agree with everything these three people say, and some of their arguments are persuasive but fallacious. Here are excerpts from the book, pp. 106-108:
To get the most out of these dialogues pay particular attention to what the “other side” says. Notice what happens when you encounter a good idea that disturbs your preconceptions. What emotions do you feel? What impulses do you experience? At such uncomfortable moments it’s only human to look for an exit: “I’d better catch up on my emails.”
Ancient peoples tended to assume that there were only two possible explanations for the existence of heaven and Earth. Either “everything just happened” or “God(s) did it,” and the latter seemed far more likely. Although they realized there was a lot they didn’t know, it did not occur to them that their limited understanding also limited their awareness of alternatives.
Physics and biology have already given us another candidate: The universe radiated outward from the Big Bang and life-forms evolved through natural selection. Some of us agree with these theories and some do not, but at least they offer a conceivable alternative. So now we have at least four options rather than two: “it just happened,” “a Creator made it,” “Big Bang plus evolution,” or a combination in which God caused the Big Bang and included evolution in the divine plan. Importantly, future scientists and philosophers may develop other credible theories about how the cosmos could be “a watch without a watchmaker.” And of course, even if we had a million legitimate options, the right answer might still be, “God did it.”
Let’s see what our three friends have to say about this topic. Theodore leads off.
Theodore: Even if I try to convince myself that the universe could have appeared out of nowhere, it just doesn’t seem plausible. Everywhere I look I find intricate order and regularity. Unbelievably complicated systems have to work with finicky precision for me to stay alive a single second. To me all of this just screams “intelligent design!” Don’t either of you ever feel that way?
Althea: Of course it’s hard to imagine how everything could function without an invisible guiding hand. But it’s hard for me to imagine a great many things that have been well-established. I am only a moderately intelligent mammal living on a little planet near a smallish sun. Why should I be able to comprehend how the whole universe works?
Agnes: We’re just a bunch of curious little critters trying to grasp infinite subtlety and complexity. Even so, I prick up my ears when I hear that physicists have found evidence of creative intelligence. Remember that YouTube video of the debate between Daniel Dennett and Dinesh D’Souza? D’Souza claimed that if certain cosmic laws had been infinitesimally different, “we would have no universe. We would have no life.” He concludes that a creative intelligence wanted us to be here, and some scientists agree with him. This is one reason I’m an agnostic instead of an atheist. …
Althea: Right, but Dennett pointed out [in Part Seven] that there may be lots of other universes which operate according to laws that prevent life from occurring. Some cosmologists even say there could be an infinite number of universes. Life might be impossible in almost all of these systems, but some of them might be suitable homes for living creatures. If these creatures didn’t know about all the other universes, it would seem as if “the” universe was specifically designed for their benefit. “Wow, how come everything is arranged so precisely? I guess there must be a God!” …
Theodore: The idea of a godless cosmos offends my intelligence. I had a logic teacher in college who often spotted a fallacious argument just by noticing that it sounded fishy. He relied more on hunches than on tight little syllogisms. His mind was equipped with a built-in nonsense-detector that sounded an alarm, and an alarm goes off in my mind when people claim that all this wonderment happened for no reason at all. [End of excerpt from Bridging the God Gap.]
So – which statements felt right to you? Which ones upset you? Which ones made you squirm because you didn’t agree but you weren’t sure how to reply? We’ll finish this conversation in my next posting.
