Three reasons why scientism should be rejected

Scientism is the view that the only things that can be known are things that can be discovered through science. That’s a very popular view, but there are at least three things wrong with it.

First,  Tough Questions Answered quotes philosopher Ed Feser, who says that the enterprise of science makes assumptions that cannot be justified by science itself.

Feser writes:

Of  its very nature, scientific investigation takes for granted such assumptions as that: there is a physical world existing independently of our minds; this world is characterized by various objective patterns and regularities; our senses are at least partially reliable sources of information about this world; there are objective laws of logic and mathematics that apply to the objective world outside our minds; our cognitive powers – of concept-formation, reasoning from premises to a conclusion, and so forth – afford us a grasp of these laws and can reliably take us from evidence derived from the senses to conclusions about the physical world; the language we use can adequately express truths about these laws and about the external world; and so on and so on.

Science assumes that those things are true, it cannot discover them.

Second, scientism cannot account for things we know apart from science.

William Lane Craig explains:

First, scientism is too restrictive a theory of knowledge. It would, if adopted, compel us to abandon wide swaths of what most of us take to be fields of human knowledge. Your friend admits this with regard to moral and aesthetic truths. On his view there is nothing good or evil, right or wrong, beautiful or ugly. But is it plausible to think that there are no aesthetic or moral truths? On your friend’s view there’s nothing wrong with torturing a little girl to death. Why should we accept such a conclusion simply because of a epistemological restriction? Isn’t this a signal that we need rather to broaden the scope of our theory so as to encompass other types of knowledge? Your friend says he will treat logical and mathematical truths as merely empirical truths. Good luck! Truths like “If p implies q, and p, then q” or “2 + 2 = 4” are to all appearances necessary truths, not merely empirical generalizations.

Third, scientism is self-refuting.

William Lane Craig explains:

Secondly, scientism is self-refuting. Scientism tells us that we should not believe any proposition that cannot be scientifically proven. But what about that very proposition itself? It cannot itself be scientifically proven. Therefore we should not believe it. Scientism thus defeats itself.

You can’t prove scientism (a theory of what we can know) using science. It refutes itself.

So, there are three reasons to reject scientism. Nothing I have said here should be taken as criticism of science, though. On the contrary – the progress of science is one of the best friends of Christian theists. We have gained a lot from the advances made by science in areas like cosmology, cosmic fine-tuning, the origin of life, the fossil record, and astrobiology. We love science. But scientism is false.

What criteria do historians use to get to the minimal facts about the historical Jesus?

Have you ever heard Gary Habermas, Michael Licona or William Lane Craig defend the resurrection of Jesus as the best explanation for the “minimal facts” about Jesus? The lists of minimal facts that they use are typically agreed to by their opponents during the debates.

For example, in his debate with Bart Ehrman, Craig was able to quote Ehrman’s own writings where he agreed that all four facts were probably true.

Excerpt:

Now in his early published work Dr. Ehrman expressed skepticism about these facts. He insisted that we cannot really affirm these facts.

[…]Dr. Ehrman has himself come to re-think his position on these issues. Inconsistencies in the details notwithstanding, he now recognizes that we have “solid traditions,” not only for Jesus’ burial, but also for the women’s discovery of the empty tomb, and therefore, he says, we can conclude with “some certainty” that Jesus was in fact buried by Joseph of Arimathea in a tomb and that three days later the tomb was found empty. 8

When I discovered that Professor Ehrman had reversed himself on this question, my admiration for his honesty and scholarly objectivity shot up. Very few scholars, once they’ve gone into print on an issue, have the courage to re-think that issue and admit that they were wrong. Dr. Ehrman’s reversal of his opinion on these matters is testimony, not merely to the force of the evidence for these four facts, but also to his determination to follow the evidence wherever it leads. What this means is that my first contention is not an issue of disagreement in tonight’s debate.

So what are the criteria that historians use to derive a list of minimal facts about Jesus?

Dr. Craig explains them in this article.

Excerpt:

The other way, more influential in contemporary New Testament scholarship, is to establish specific facts about Jesus without assuming the general reliability of the Gospels. The key here are the so-called “Criteria of Authenticity” which enable us to establish specific sayings or events in Jesus’ life as historical. Scholars involved in the quest of the historical Jesus have enunciated a number of these critieria for detecting historically authentic features of Jesus, such as dissimilarity to Christian teaching, multiple attestation, linguistic semitisms, traces of Palestinian milieu, retention of embarrassing material, coherence with other authentic material, and so forth.

It is somewhat misleading to call these “criteria,” for they aim at stating sufficient, not necessary, conditions of historicity. This is easy to see: suppose a saying is multiply attested and dissimilar but not embarrassing. If embarrassment were a necessary condition of authenticity, then the saying would have to be deemed inauthentic, which is wrong-headed, since its multiple attestation and dissimilarity are sufficient for authenticity. Of course, the criteria are defeasible, meaning that they are not infallible guides to authenticity. They might be better called “Indications of Authenticity” or “Signs of Credibility.”

In point of fact, what the criteria really amount to are statements about the effect of certain types of evidence upon the probability of various sayings or events in Jesus’ life. For some saying or event S and evidence of a certain type E, the criteria would state that, all things being equal, the probability of S given E is greater than the probability of S on our background knowledge alone. So, for example, all else being equal, the probability of some event or saying is greater given its multiple attestation than it would have been without it.

What are some of the factors that might serve the role of E in increasing the probability of some saying or event S? The following are some of the most important:

(1) Historical congruence: S fits in with known historical facts concerning the context in which S is said to have occurred.

(2) Independent, early attestation: S appears in multiple sources which are near to the time at which S is alleged to have occurred and which depend neither upon each other nor a common source.

(3) Embarrassment: S is awkward or counter-productive for the persons who serve as the source of information for S.

(4) Dissimilarity: S is unlike antecedent Jewish thought-forms and/or unlike subsequent Christian thought-forms.

(5) Semitisms: traces in the narrative of Aramaic or Hebrew linguistic forms.

(6) Coherence: S is consistent with already established facts about Jesus.

For a good discussion of these factors see Robert Stein, “The ‘Criteria’ for Authenticity,” in Gospel Perspectives I, ed. R. T. France and David Wenham (Sheffield, England: JSOT Press, 1980), pp. 225-63.

Notice that these “criteria” do not presuppose the general reliability of the Gospels. Rather they focus on a particular saying or event and give evidence for thinking that specific element of Jesus’ life to be historical, regardless of the general reliability of the document in which the particular saying or event is reported. These same “criteria” are thus applicable to reports of Jesus found in the apocryphal Gospels, or rabbinical writings, or even the Qur’an. Of course, if the Gospels can be shown to be generally reliable documents, so much the better! But the “criteria” do not depend on any such presupposition. They serve to help spot historical kernels even in the midst of historical chaff. Thus we need not concern ourselves with defending the Gospels’ every claim attributed to Jesus in the gospels; the question will be whether we can establish enough about Jesus to make faith in him reasonable.

And you can see Dr. Craig using these criteria to defend minimal facts in his debates. For example, in his debate with Ehrman, he alludes to the criteria when making his case for the empty tomb.

Here, he uses multiple attestation and the criteria of embarrassment:

Among the reasons which have led most scholars to this conclusion are the following:

1. The empty tomb is also multiply attested by independent, early sources.

Mark’s source didn’t end with the burial, but with the story of the empty tomb, which is tied to the burial story verbally and grammatically. Moreover, Matthew and John have independent sources about the empty tomb; it’s also mentioned in the sermons in the Acts of the Apostles (2.29; 13.36); and it’s implied by Paul in his first letter to the Corinthian church (I Cor. 15.4). Thus, we have again multiple, early, independent attestation of the fact of the empty tomb.

2. The tomb was discovered empty by women.

In patriarchal Jewish society the testimony of women was not highly regarded. In fact, the Jewish historian Josephus says that women weren’t even permitted to serve as witnesses in a Jewish court of law. Now in light of this fact, how remarkable it is that it is women who are the discoverers of Jesus’ empty tomb. Any later legendary account would certainly have made male disciples like Peter and John discover the empty tomb. The fact that it is women, rather than men, who are the discoverers of the empty tomb is best explained by the fact that they were the chief witnesses to the fact of the empty tomb, and the Gospel writers faithfully record what, for them, was an awkward and embarrassing fact.

There are actually a few more reasons for believing in the empty tomb that he doesn’t go into in the debate, but you can find them in his written work. For example, in his essay on Gerd Ludemann’s “vision” hypothesis. That essay covers the reasons for all four of his minimal facts.

So, if you are going to talk about the resurrection with a skeptic, you don’t want to invoke the Bible as some sort of inerrant/inspired Holy Book.

Try this approach instead:

  1. Explain the criteria that historians use to get their lists of minimal facts
  2. Explain your list of minimal facts
  3. Defend your list of minimal facts using the criteria
  4. Cite skeptics who admit to each of your minimal facts, to show that they are widely accepted
  5. List some parts of the Bible that don’t pass the criteria (e.g. – guard at the tomb, Matthew earthquake)
  6. Explain why those parts don’t pass the criteria, and explain that they are not part of your case
  7. Challenge your opponent to either deny some or all the facts, or propose a naturalistic alternative that explains the facts better than the resurrection
  8. Don’t let your opponent attack any of your minimal facts by attacking other parts of the Bible (e.g. – the number of angels being one or two, etc.)

And just keep in mind that there is no good case for the resurrection that does not make heavy use of the early creed in 1 Corinthians 15:3-8. You have to use that – it’s the law.

Back to the minimal facts criteria. The best essay on the minimal facts criteria that I’ve read is the one by Robert H. Stein in “Contending with Christianity’s Critics“. It’s a good short essay that goes over all the historical criteria that are used to derive the short list of facts from which we infer the conclusion “God raised Jesus from the dead”. That whole book is really very, very good.

Is there a smooth pathway from micro-evolution to macro-evolution?

From Luke Nix who blogs at Faithful Thinkers.

Excerpt:

Macroevolutionary changes are a lot of microevolutionary changes, but they are in a specific series that follow a specific pathway. The missing premise in this argument is that the pathway from ancestor to claimed offspring (many generations down the road) is clear of obstacles.

In his book, “The Edge of Evolution” Michael Behe shows that scientists have observed such an obstacle in the lab. The obstacle was not time, it is in the genetic pathway that must be traversed if macroevolutionary changes are to take place in reality. Since an obstacle has been observed, we now have a false premise in the argument. Since there is a false premise, the argument fails. There is a difference between micro- and macro-evolutionary changes. A lot of microevolutionary changes are necessary for macroevolution, but they are not sufficient. The other sufficient condition (a clear genetic pathway) still has yet to be met. Since both sufficient conditions for macroevolution have not been met, it has not been demonstrated. And since changes over time has been demonstrated, there is a need to distinguish between the two. To prevent confusion about what we know to be true and what we don’t, this distinction must be made.

There is only one way that this can be overcome by the naturalist: find a pathway that would be clear by default in nature. Notice that I have added one more piece to the missing premise above: “…clear by default in nature“. I have to add that last qualification because as scientists are looking for a way to overcome this obstacle, they are introducing their own intelligence- fine-tuning the process, then “allowing nature to take its course”. Their conclusion of naturalistic macroevolution will depend on a premise that is founded on intelligence. That would undermine the whole argument for naturalistic (macro)evolution.

This is one of the ways to show that evolution is true – by showing a pathway to macro-evolutionary change in the lab. If people expect me to believe in the grandiose claims of fully naturalistic evolution through a stepwise process, then why can’t I see the pathway myself? If you make the claim that it happened, then I want to see the evidence for the claim.
