Tom Bethell, who writes regularly for the American Spectator, is a favorite author of mine. His writings on science, economics, the environment, and just about everything else under the sun—and indeed about the sun itself—are fascinating in their clarity and pure logic. In today's edition of National Review Online, a perfectly fabulous publication read and admired by absolutely all of the Smart Set, Bethell writes brilliantly on the relative merits of the theories of evolution and intelligent design. You must read the entire article, lest you remain far less brilliant than you could be (and it will only be your own damned fault), but the following excerpt illustrates an important point which the present author has himself made over at the American Spectator, that both evolution and intelligent design are theories that are not falsifiable—and Bethell does us a great favor by reminding us that the philosopher who invented the "falsifiability" test himself said that the theory of evolution by natural selection abysmally failed it!. To wit:
Charles Krauthammer tells us that Isaac Newton was religious and if he saw no conflict between science and religion, why can't we take our thin gruel of evolutionary science like good children and be satisfied, without dragging a Designer into the picture?
Because it isn't real science, Charles. Newton, in fact, thought that the "most beautiful system" of sun, planets, and comets could "only proceed from the counsel and dominion of an intelligent and powerful being." But the laws of physics that govern these motions are simplicity itself compared with the immense complexity of the biological machinery that governs the development, proliferation, growth, and aging of millions of reproductive species. These mechanisms have yet to be discovered or described. To believe that the feeble tautology of natural selection — laissez-faire political economy from the 1830s imported into biology — constitutes a sufficient explanation of the marvels of nature is to display a credulity that makes our fundamentalists seem sagacious by comparison.
George Will has made one accurate criticism of the idea he so dislikes: "The problem with intelligent design is not that it is false but that it is not falsifiable. Not being susceptible to contradicting evidence, it is not a testable hypothesis." This is true; but he should have added that Darwin's theory of evolution by natural selection is not falsifiable either. Darwin's claim to fame was his discovery of a mechanism of evolution; he accepted "survival of the fittest" as a good summary of his natural-selection theory. But which ones are the fittest? The ones that survive. There is no criterion of fitness that is independent of survival. Whatever happens, it is the "fittest" that survive — by definition. This, just like intelligent design, is not a testable hypothesis. As the eminent philosopher of science Karl Popper said, after discussing this problem that natural selection cannot escape: "There is hardly any possibility of testing a theory as feeble as this." Popper was the first to propose falsification as the line of demarcation between theories that are scientific and those that are not; both intelligent design and natural selection fall by this standard.
The underlying problem, rarely discussed, is that the conclusions of evolutionism are based not on science, but on a philosophy: the philosophy of materialism, or naturalism. Living creatures, including human beings, are here on Earth, and we got here somehow. If atoms and molecules in motion are all that exist, then their random interactions must account for everything that exists, including us. That is the true underpinning of Darwinism. What needs to be examined in detail is not so much the religion behind intelligent design as the philosophy behind evolution.
Bloody well right, Tom, as ever.
