I, too, want the world to be a better place. This is my reason for wanting people to understand and accept evolutionary theory: I believe that their salvation may depend on it! How so? By opening their eyes to the dangers of pandemics, degradation of the environment, and loss of biodiversity, and by informing them about some of the foibles of human nature. So isn’t my belief that belief in evolution is the path to salvation a religion? No; there is a major difference. We who love evolution do not honor those whose love of evolution prevents them from thinking clearly and rationally about it! On the contrary, we are particularly critical of those whose misunderstandings and romantic misstatements of these great ideas mislead themselves and others. In our view, there is no safe haven for mystery or incomprehensibility. Yes, there is humility, and awe, and sheer delight, at the glory of the evolutionary landscape, but it is not accompanied by, or in the service of, a willing (let alone thrilling) abandonment of reason. So I feel a moral imperative to spread the word of evolution, but evolution is not my religion. I don’t have a religion.
