In the delightfully funny “Big Bang Theory” Penny’s boyfriend, Zack, wants to talk with the genius scientists who live across the hall because the thing he loves about science is “there’s no one right answer.” The laugh track cuts in and the “audience” laughs while the four scientists look at one another with dismay. I hate laugh tracks, but while it is a funny moment it is also a bit sad, because Zach’s statement reflects much common opinion today when an alarming number of “educated” people in this country (which group does not, apparently, include Zach) have no idea what science is and what it is not. Just consider: a recent study done at the University of Texas revealed that four in ten public school teachers of biology think that humans and dinosaurs roamed the earth at the same time; three out of five adult Americans do not know that DNA governs heredity; and one in four Americans thinks the sun revolves around the earth. And most Americans, I dare say, confuse science with technology.
Science is a word that describes a particular method of getting at the truth about our world and the universe in general. It leans on empirical evidence, gathered by the five senses, and/or mathematical proof. Both empirical evidence and mathematical proof are accessible to others in the scientific community and no scientific claim is accepted unless it is verifiable by anyone at any time. This notion of independent verification is key to the scientific method. When the claim was made not long ago that cold fusion had been discovered there was much excitement until it was later shown by other scientists that there were errors in the testing procedure and the claims were proved false. That is also a key: the claims must be open to independent testing and it must be possible to prove them false. If they cannot be proved false, they are accepted as true — subject to further tests.
Evolution is a scientific theory that has been supported again and again by empirical evidence to the point now where it is indisputable fact. But there are those who are convinced that evolution is incompatible with Genesis and either do not want evolution taught in the schools or want it taught alongside of creationism, or what has come to be called “intelligent design” in an attempt to make it sound more respectable. Both of these two views argue that God created the world and the assumption is that He couldn’t have done this if species evolved as scientists contend.
Now there are two things we need to consider: (1) are evolution and creationism compatible? and (2) is creationism science? The answer to the latter question is a resounding “no,” since independent testing is not possible; nor is it possible to prove the theory false. What would even count as a test for this view? But the answer to the first question is “yes,” and that’s why the battle that is going on in the schools is absurd. Both creationism and evolution can be true (for different reasons), since God could have chosen to create animal and plant life through evolution. But since creationism is not science, it should not be taught in the schools: it is a matter of faith, not reason. Thus while students should be taught evolution in science classes, they are also perfectly free to accept creationism on faith.
One is reminded of the medieval battle between reason and faith that went on in the universities and which the Catholic Church attempted in its way to adjudicate. In the end, St. Thomas Aquinas wrote his monumental Suma Theologica to reconcile faith and reason, to show that they were perfectly compatible. If there were conflicts, of course, Thomas insisted that faith had the final word. That was where things stood when Galileo ran into the Inquisition and had to recant and allow that the evidence he had about the earth’s motion was merely a theory, since it was in direct conflict with the Bible which speaks of the motion of the sun. Now, except for that 25% exposed by the Texas survey noted above, we now know that Galileo was right, and most regard the Biblical statements as metaphorical — true in their way, but not matters of science.
The same seems to me to be the case with creationism: it may be true in its way, but it most assuredly is not science. And since it is a matter of faith, not reason, it should not be taught in the schools — especially in schools supported by taxes in a country that was founded on the separation of church and state. But it should not be taught in any school as science, which it clearly is not.
