Mistaken Objections that Seek to Trivialize Fine-Tuning
by Allen Hainline
This is my third blog in a series on fine-tuning as evidence for God. Here are the first and second blogs, which deal with the philosophical background. Before I share the evidence I want to refute or at least rebut a few objections seen at the popular level but rarely in scholarly circles – otherwise, readers might just ignore the argument no matter what fine-tuning evidence is presented. Generally one should be wary of dismissive claims that attempt to trivialize what many intelligent physicists and philosophers think is worthy of discussion and evaluation. Even hardened skeptics admit that the fine-tuning evidence is worth evaluating. The late Christopher Hitchens answered a question concerning what is the best argument from the other side: “I think everyone of us picks the fine-tuning one as the most intriguing… you have to spend time thinking about it, working on it. It’s not a trivial [argument].” But let’s consider some popular level responses that seek to trivialize fine-tuning.
The Universe is not Adapted to Us, We’re Adapted to the Universe
This was the primary response given by atheist philosopher Peter Boghossian when I discussed fine-tuning in his recent Q&A session at UT Dallas. This response is based on a fundamental misunderstanding of the articles in the physics literature as addressed in my previous blog. The fine-tuning deals with how the physics has to be setup before life gets started so without fine-tuning there is no evolutionary way for adapting life to the universe.
Aren’t Any Set of Physical Constants Just As Likely As Any Other?
About 5 years ago I had the opportunity to engage in sort of a friendly debate with the head of the science department at the high school where my daughter and son attended. She was taking a “Theory of Knowledge” class as part of the International Baccalaureate curriculum and the instructor needed to provide an example to students of presentations of opposing viewpoints. He had heard that I was an advocate of Intelligent Design and wanted each of us to make presentations supporting our viewpoints. He is an excellent teacher and heads the science department and I was somewhat nervous to be engaging in my first public debate of this type – this was before I had read a dozen or so books on fine-tuning and taken a graduate course on Cosmology. However, the instructor gave a surprisingly weak response to the fine-tuning evidence that I had presented. He set up an analogy for the students of dealing out a set of 5 cards from a set of 10 packs of cards with different backings. The odds of dealing out any particular hand were extraordinarily low but he argued that since any set of cards was just as likely as any other set, no inference could be made that the cards were not dealt at random. This was supposed to refute a design inference because any set of constants of physics is just as likely as any other.
However, the assumption that any set of constants is just as likely as any other is the very thing that we want to know. Starting off with that as an assumption begs the question against design…
