“They know not what they do”

We just celebrated the last Sunday of the Church Year–some call it the Sunday of the Fulfillment or Christ the King Sunday.  And the Gospel reading for this triumphant, climactic day is about. . . Christ on the Cross (Luke 23:27-43).  Our pastor preached on some words of His that I’ve never heard treated like this:  “They know not what they do” (Luke 23:34).

The sermon made me realize that the epistemological problem–what do we know and how do we know it?–is not just a theoretical question for academic philosophers. In the course of our everyday lives, we have to function with major gaps in our knowledge. [Read more...]

Plantinga on Science, Naturalism, and Faith

Alvin Plantinga is a highly-respected philosopher, respected even by those who disagree with him.  An evangelical, Reformed Christian, Plantinga has written a new book, Where the Conflict Really Lies: Science, Religion, and Naturalism.

It has received a glowing review from Thomas Nagel, an atheist–in the New York Review of Books, no less–in which he says that Plantinga’s arguments help him to realize that Christians are, in fact, rational.  And that his own side has some explaining to do.

The gulf in outlook between atheists and adherents of the monotheistic religions is profound. We are fortunate to live under a constitutional system and a code of manners that by and large keep it from disturbing the social peace; usually the parties ignore each other. But sometimes the conflict surfaces and heats up into a public debate. The present is such a time.

One of the things atheists tend to believe is that modern science is on their side, whereas theism is in conflict with science: that, for example, belief in miracles is inconsistent with the scientific conception of natural law; faith as a basis of belief is inconsistent with the scientific conception of knowledge; belief that God created man in his own image is inconsistent with scientific explanations provided by the theory of evolution. In his absorbing new book, Where the Conflict Really Lies, Alvin Plantinga, a distinguished analytic philosopher known for his contributions to metaphysics and theory of knowledge as well as to the philosophy of religion, turns this alleged opposition on its head. His overall claim is that “there is superficial conflict but deep concord between science and theistic religion, but superficial concord and deep conflict between science and naturalism.” By naturalism he means the view that the world describable by the natural sciences is all that exists, and that there is no such person as God, or anything like God.

Plantinga’s religion is the real thing, not just an intellectual deism that gives God nothing to do in the world. He himself is an evangelical Protestant, but he conducts his argument with respect to a version of Christianity that is the “rough intersection of the great Christian creeds”—ranging from the Apostle’s Creed to the Anglican Thirty-Nine Articles—according to which God is a person who not only created and maintains the universe and its laws, but also intervenes specially in the world, with the miracles related in the Bible and in other ways. It is of great interest to be presented with a lucid and sophisticated account of how someone who holds these beliefs understands them to harmonize with and indeed to provide crucial support for the methods and results of the natural sciences.

Plantinga discusses many topics in the course of the book, but his most important claims are epistemological. He holds, first, that the theistic conception of the relation between God, the natural world, and ourselves makes it reasonable for us to regard our perceptual and rational faculties as reliable. It is therefore reasonable to believe that the scientific theories they allow us to create do describe reality. He holds, second, that the naturalistic conception of the world, and of ourselves as products of unguided Darwinian evolution, makes it unreasonable for us to believe that our cognitive faculties are reliable, and therefore unreasonable to believe any theories they may lead us to form, including the theory of evolution. In other words, belief in naturalism combined with belief in evolution is self-defeating. However, Plantinga thinks we can reasonably believe that we are the products of evolution provided that we also believe, contrary to naturalism, that the process was in some way guided by God.

Nagel gives a very clear summary of Plantinga’s epistemology, which emphasizes that there are different kinds of “warrants” for  beliefs.  Faith itself, Plantinga argues, is such a warrant:

Faith, according to Plantinga, is another basic way of forming beliefs, distinct from but not in competition with reason, perception, memory, and the others. However, it is a wholly different kettle of fish: according to the Christian tradition (including both Thomas Aquinas and John Calvin), faith is a special gift from God, not part of our ordinary epistemic equipment. Faith is a source of belief, a source that goes beyond the faculties included in reason.God endows human beings with a sensus divinitatis that ordinarily leads them to believe in him. (In atheists the sensus divinitatis is either blocked or not functioning properly.)2 In addition, God acts in the world more selectively by “enabling Christians to see the truth of the central teachings of the Gospel.”

If all this is true, then by Plantinga’s standard of reliability and proper function, faith is a kind of cause that provides a warrant for theistic belief, even though it is a gift, and not a universal human faculty. (Plantinga recognizes that rational arguments have also been offered for the existence of God, but he thinks it is not necessary to rely on these, any more than it is necessary to rely on rational proofs of the existence of the external world to know just by looking that there is beer in the refrigerator.)

It is illuminating to have the starkness of the opposition between Plantinga’s theism and the secular outlook so clearly explained. My instinctively atheistic perspective implies that if I ever found myself flooded with the conviction that what the Nicene Creed says is true, the most likely explanation would be that I was losing my mind, not that I was being granted the gift of faith. From Plantinga’s point of view, by contrast, I suffer from a kind of spiritual blindness from which I am unwilling to be cured. This is a huge epistemological gulf, and it cannot be overcome by the cooperative employment of the cognitive faculties that we share, as is the hope with scientific disagreements.

Faith adds beliefs to the theist’s base of available evidence that are absent from the atheist’s, and unavailable to him without God’s special action. These differences make different beliefs reasonable given the same shared evidence. An atheist familiar with biology and medicine has no reason to believe the biblical story of the resurrection. But a Christian who believes it by faith should not, according to Plantinga, be dissuaded by general biological evidence. Plantinga compares the difference in justified beliefs to a case where you are accused of a crime on the basis of very convincing evidence, but you know that you didn’t do it. For you, the immediate evidence of your memory is not defeated by the public evidence against you, even though your memory is not available to others. Likewise, the Christian’s faith in the truth of the gospels, though unavailable to the atheist, is not defeated by the secular evidence against the possibility of resurrection.

For the purposes of our discussion, could we make some topics off-limits?  First, please do not dismiss Plantinga as a “theistic evolutionist”; he may be one, but I think that’s too simplistic, and he is also giving some “warrants” for creationism.  Second, let’s not get into the debate here between “evidentialist”  and “presuppositionalist” apologetics.  There is actually some of both here, as Plantinga is supporting the reality of objective evidence as well as the fact–which Lutherans, at least, must not deny–that faith is a gift.  The ultimate cause of atheism, as Plantinga says and as the atheist Nagel admits, is “spiritual blindness.”  Finally, let’s not have any attacks on Plantinga as a Calvinist.  (Comments that violate these terms may be deleted.)

Can Science explain everything?

From David Wheeler at the Chronicle of Higher Education blog:

There’s a new bully on the intellectual block, shoving scholars around. Lots of them are caving into the threats. The bully’s name is “scientism,” the belief that science has a monopoly on all real knowledge. All other knowledge, scientism asserts, is simply opinion, irrationality, or utter nonsense.

That was the perspective Ian Hutchinson, professor of nuclear science and engineering at the Massachusetts Institute of Technology, offered at an event titled “Can Science Explain Everything?” at the American Association for the Advancement of Science this week. . . .

Hutchinson, theauthor of Monopolizing Knowledge: A Scientist Refutes Religion-Denying, Reason-Destroying Scientism, said that science is in the middle of confrontation with religious faith and with many other forms of belief. He is proud of science’s achievements thus far. But he thinks that, in part because of its overwhelming success, members of other disciplines, seeking the authority that science has, try to make themselves out to be scientists. An alternative course, he suggests, would be for scholars such as sociologists and political scientists to firmly declare that they have ways of building knowledge that are simply different from science, not “unscientific.”

Science has two key elements, reproducibility and clarity, Hutchinson said. Reproducibility means essentially that an experiment done in one place by one person can be repeated somewhere else by someone else. Clarity refers to the unambiguous nature of science’s measurements, descriptions, and classifications. History is an example of a discipline that has produced real knowledge that is not scientific knowledge, he said. History at its best is based on facts, but historians cannot reproduce Henry VIII’s exploits to find out if accounts of them are true.

Mr. Hutchinson listed other phenomena that may be “true” but that he believes are outside of science’s scope: the beauty of a sunset, the justice of a verdict, or the terror of a war. Many humans may share similar perceptions of these phenomenon but the basis of those perceptions will lack clarity. “Ambiguity is an intrinsic part of these things,” he said.

Where, exactly, does God fit into this picture? Mr. Hutchinson says that while the universe has physical laws, God may be behind them. Science would be helpless to detect an act of God that violates the laws of physics since it would not be reproducible. Scientists should have no problem being religious, he said.
Enter Lisa Randall, a woman with an astonishing range of achievements from a libretto for an opera to experiments at the Large Hadron Collider, in Geneva. She studies cosmology and theoretical particle physics and is the author of “Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World.”

While polite in tone, Ms. Randall said the term “scientism” was embarrassing and an act of name calling, at a time when the discussion about tackling the world’s problems needs to be elevated. “It shouldn’t be embarrassing or quaint to be earnest about facts or logic,” she said. And, she added “Why do politicians feel comfortable talking about God and religion and not about science and mathematics?”

Art is important she said, but it ultimately operates through the filter of human perceptions and emotions. Religion, she said, is also a human phenomenon that serves social needs. “If you say it makes me happy or helps me live my life, I’m not going to stop you,” she said.

But, she said, religion is different to different people. Scientists, while they have their petty fights, are ultimately able to create knowledge they can agree on.

In audience questions after the two talks, one person cut to the chase and demanded “yes” or “no” answers to the evening’s challenge: “Can science explain everything?”

“No,” said Mr. Hutchinson.

“We don’t know,” said Ms. Randall.
