A few weeks back, Mathew C. Nisbet and Chris Mooney wrote an article for the Washington Post arguing that defenders of evolution undermine their cause when they seek to promote atheism as well. I wholly agree with this argument. There is no inherent conflict between a belief in evolution and a theistic worldview. The theory of evolution explains how human beings and other species evolved, and is a very effective way of understanding biological systems. Evolution does not purport to answer the question of how things began, or whether there was a Prime Mover who initiated the evolutionary process or perhaps even guided it. It is a scientific explanation about the natural world that we experience. When evolution advocates embrace atheistic evangelism, they not only misrepresent evolutionary theory, they also undermine their ability to communicate with a largely God-fearing public.
Nisbet and Mooney make this point in the context of a broader discussion of how scientists need to "sell" scientific understanding. While Mooney and I clearly have our differences, I generally think they are correct here as well. If scientists want to have a greater influence on the public, they need to learn to talk to laypeople differently than they talk to other scientists. This does not require misrepresenting scientific research, nor does it require pretending that science can answer what are essentially normative policy questions. But it definitely requires recognizing the challenge of communicating scientific information to a relatively scientifically ignorant public.
