Professor Krauss is a physicist at Arizona State University.
(p. A15) My practice as a scientist is atheistic. That is to say, when I set up an experiment I assume that no god, angel or devil is going to interfere with its course; and this assumption has been justified by such success as I have achieved in my professional career. I should therefore be intellectually dishonest if I were not also atheistic in the affairs of the world.
— J.B.S. Haldane
J.B.S. Haldane, an evolutionary biologist and a founder of population genetics, understood that science is by necessity an atheistic discipline. As Haldane so aptly described it, one cannot proceed with the process of scientific discovery if one assumes a “god, angel, or devil” will interfere with one’s experiments. God is, of necessity, irrelevant in science.
Faced with the remarkable success of science to explain the workings of the physical world, many, indeed probably most, scientists understandably react as Haldane did. Namely, they extrapolate the atheism of science to a more general atheism.
While such a leap may not be unimpeachable it is certainly rational, as Mr. McGinn pointed out at the World Science Festival. Though the scientific process may be compatible with the vague idea of some relaxed deity who merely established the universe and let it proceed from there, it is in fact rationally incompatible with the detailed tenets of most of the world’s organized religions. As Sam Harris recently wrote in a letter responding to the Nature editorial that called him an “atheist absolutist,” a “reconciliation between science and Christianity would mean squaring physics, chemistry, biology, and a basic understanding of probabilistic reasoning with a raft of patently ridiculous, Iron Age convictions.”
