Two days ago I analyzed former philosophy professor Gregory Bassham’s unpublished critique of my book Faith versus Fact. (I also discovered that I analyzed the paper on this site in 2017 at greater length, so it’s been unpublished for at least three years. Shoot me for forgetting!). Bassham claimed that religion has its own “ways of knowing” that aren’t based on science, much less empirical observation. His argument, I contended, falls flat.
Now I found a similar critique from Bassham on Academia.edu about my argument in the book that science does not depend on faith. I won’t say he’s obsessed with me, but if he wants to get his ideas out, he should concentrate on getting them published.
You can see his second critique by clicking on the screenshot below.
My argument in the book, also made in my Slate piece “No faith in science,” is aimed at a common jab at science made by believers. “Science,” they say, “is based on faith, just like religion.” In effect, they’re saying, “See, you’re just as bad as we are!”
Read below if you want; it’s a short paper (12 pages double spaced).
In my book and the Slate article I contend that the religionists’ argument depends on two different conceptions of faith, described in the Slate piece like this:
You have faith (i.e., confidence) that the sun will rise tomorrow because it always has, and there’s no evidence that the Earth has stopped rotating or the sun has burnt out. You have faith in your doctor because, presumably, she has treated you and others successfully, and you know that what she prescribes is tested scientifically. You wouldn’t go to a shaman or a spiritual healer for strep throat—unless you want to waste your money.
The conflation of faith as “unevidenced belief” with faith as “justified confidence” is simply a word trick used to buttress religion. In fact, you’ll never hear a scientist saying, “I have faith in evolution” or “I have faith in electrons.” Not only is such language alien to us, but we know full well how those words can be misused in the name of religion.
It goes on, and I don’t want to reprise the argument, which is a short one at Slate. In the present paper, Bassham presents a variety of ways that, he thinks, science depends on “faith”, but it turns out that all of these are “confidence-justified-by-experience” construals of that word.
First, though, he reprises word for word what he wrote in the Faith vs. Fact critique when trying to argue that religion is not based on “faith = belief without evidence.” You’ve seen this before, so he’s self plagiarizing:
There are many widely accepted conceptions of faith that do not view it as evidence-free belief. Among these are the Catholic “propositional” view of faith as assent to revealed truths on the authority of God the revealer; the Calvinist conception of faith as firm belief in key tenets of the Christian faith as a result of the internal instigation of the Holy Spirit; the modern Protestant “voluntarist” view of faith as interpretive trust in the self-revealing actions of God within human history; and the modern “Existentialist” conception of faith as an attitude of commitment, acceptance, and “total interpretation” made by the whole person. None of these common views of faith see it as an evidence-free form of cognition, or as inherently irrational.
Where’s the beef—the bit about “evidence”? The paragraph above doesn’t do a lot of work towards showing a similarity between what scientists deem as “faith” (justified confidence) and religious faith. So let’s look at one of Bassham’s arguments that scientist really do have a religious-like faith:
Finally, what of the claims that science is based on faith because of its commitments to the orderliness of nature and an unexplained set of physical laws?
These are really separate issues, but Coyne lumps them together and dismisses both with the following quick retort:
The orderliness of nature—the so-called set of natural laws—is not an assumption but an observation. It is logically possible that the speed of light in a vacuum could vary from place to place, and while we’d have to adjust our theories to account for that, or dispense with certain theories altogether, it wouldn’t be a disaster. . . . The laws of nature, then, are regularities (assumptions, if you will) based on experience, the same kind of experience that makes us confident that we’ll see another sunrise (p. 210).
Here Coyne completely misses the point at issue. The claim that scientists’ belief in the orderliness of nature is based on faith is grounded in two obvious features of science: (1) its working assumption, based on extensive but nevertheless limited evidence, that the laws of nature always operate everywhere in the universe, and (2) its resort to inductive reasoning to predict future events based on past observations. Both points require comment.
Since Francis Bacon, it has been clear that scientists regularly make claims that are not 100 percent certain because they go beyond the available evidence. For instance, they often make universal generalizations (statements of the form “All A’s are B’s”) based upon limited evidence. This is one reason why, as Coyne himself admits (33-34), all scientific theories and claims are tentative, revisable, and falsifiable. Thus, when scientists assume that basic scientific laws like the speed of light operate always and everywhere in the universe, they are not simply, as Coyne claims, making an “observation.” It is impossible to “observe” either future events or (trivially) events in unobserved parts of the universe. Thus, when scientists assume that the speed of light is a “regularity” that remains absolutely invariant, they are making a universal generalization that goes beyond the available evidence. In other words, they are holding “a belief which is not based on proof.” This is what defenders of the “science is based on faith” argument mean when they claim that scientists’ belief in the orderliness of nature is based on “faith.”
In other words, says Bassham, our assumption that the speed of light is a constant throughout the universe is an act of “faith” comparable to the claim that “belief in Jesus as your savior will get you to Heaven”. And that is bogus. The speed of light in a vacuum can be measured in several ways, and incorporated into physical theories that apply elsewhere than in a laboratory on Earth, and, as far as we know now, is a constant. We do have evidence, just as we have evidence that other physical constants apply in places other than on Earth. So our inference to the best explanation is that the speed of light is constant in a vacuum.
Only a faith-osculator would argue that the speed-of-light claim is bascially the same as claiming that Jesus Christ, the son of God (as well as God himself) died and was resurrected so you can go to heaven, a belief based on at least five distinct empirical claims, all of them unevidenced.
In fact, there are some who have suggested that the speed of light is variable (see here and here, for instance). I’m not sure how much credibility the VSL (variable speed of light) view has, but the important thing is that we hold to a constant c because that’s what the evidence shows, but we could relinquish it if the evidence shows otherwise.
In contrast, no Christian will abandon the Jesus idea even though there’s not a scintilla of evidence for it from the get-go. So, “faith” in science 1, “faith” in Christianity, -100.
All of Bassham’s arguments for “faith” as a tenet of science are similar to the above, and I’ll let you grapple with them yourself. To end, I’ll give a quote from philosophers J. P. Moreland and William Lane Craig (oy!), which Bassham quotes to show how science depends on faith:
Science cannot be practiced in thin air. In fact, science itself presupposes a number of substantive philosophical theses which must be assumed if science is even going to get off the runway. . . . Here is a list of some of the philosophical presuppositions of science: (1) The existence of a theory-independent, external world; (2) the orderly nature of the external world; (3) the knowability of the external world; (4) the existence of truth; (5) the laws of logic; (6) the reliability of our cognitive and sensory faculties to serve as truth gatherers and as a source of justified true beliefs in our intellectual environment; (7) the adequacy of language to describe the world; (8) the existence of values used in science (e.g., “test theories fairly and report test results honestly”); (9) the uniformity of nature and induction; (10) the existence of numbers.
I would claim that all of these are inferences to the best explanation, though #6 is clearly not what scientists believe since we know that in some ways our faculties are faulty (that’s what optical illusions are about). #7 is dubious because nobody argues that (viz., quantum mechanics), and a few of the others, like “the existence of numbers” are not articles of faith.
Knock yourself out!
