Stephen Barr,
The Design of Evolution (
Communion and Stewardship is the document that I just cited in my post above):
"But
Communion and Stewardship also explicitly warns that the word “random” as used by biologists, chemists, physicists, and mathematicians in their technical work does not have the same meaning as the words “unguided” and “unplanned” as used in doctrinal statements of the Church. In common speech, “random” is often used to mean “uncaused,” “meaningless,” “inexplicable,” or “pointless.” And there is no question that some biologists, when they explain evolution to the public or to hapless students, do argue from the “randomness” of genetic mutations to the philosophical conclusion that the history of life is “unguided” and “unplanned.” Some do this because of an anti-religious animus, while others are simply careless.
"When scientists are actually doing science, however, they do not use the words “unguided” and “unplanned.” The Institute for Scientific Information’s well-known Science
Citation Index reveals that only 48 papers exist in the scientific literature with the word “unguided” in the title, most having to do with missiles. Only 467 have the word “unplanned,” almost all referring to pregnancies or medical procedures. By contrast there are 52,633 papers with “random” in the title, from all fields of scientific research. The word “random” is a basic technical term in most branches of science. It is used to discuss the motions of molecules in a gas, the fluctuations of quantum fields, noise in electronic devices, and the statistical errors in a data set, to give but a few examples. So if the word “random” necessarily entails the idea that some events are “unguided” in the sense of falling “outside of the bounds of divine providence,” we should have to condemn as incompatible with Christian faith a great deal of modern physics, chemistry, geology, and astronomy, as well as biology.
“This is absurd, of course. The word “random” as used in science does not mean uncaused, unplanned, or inexplicable; it means uncorrelated. My children like to observe the license plates of the cars that pass us on the highway, to see which states they are from. The sequence of states exhibits a degree of randomness: a car from Kentucky, then New Jersey, then Florida, and so on”because the cars are uncorrelated: Knowing where one car comes from tells us nothing about where the next one comes from. And yet, each car comes to that place at that time for a reason. Each trip is planned, each guided by some map and schedule. Each driver’s trip fits into the story of his life in some intelligible way, though the story of these drivers’ lives are not usually closely correlated with the other drivers’ lives.”
