The Value of Evolution, and the Poverty of creationism

“…In the example of evolution, the basic concepts are much easier to grasp, and should be within the reach of anyone who chooses to think about them with an open mind. However, here the challenge to acceptance is not one of the inaccessibility of the theory, but the implications that it has for existing powerful world views.

“On the other hand, as Steven Pinker has pointed out, the ramifications of natural selection are multiple. And, relatively, they are easily, if uneasily, understood: the Earth and life on it are far older than the Bible suggests. Species are not fixed entities created at one time. They rise, fall, become extinct, and there is no purpose, no forethought in these patterns. We can explain these processes now without reference to the supernatural. We ourselves are related, however distantly, to all living things. We can explain our own existence without reference to the supernatural. We may have no purpose at all except to continue. We have a nature derived in part from our evolutionary past. Underlying natural selection are physical laws. The evolved material entity we call the brain is what makes consciousness possible. When it is damaged, so is mental function. There is no evidence for an immortal soul, and no good reason beyond fervent hope that consciousness survives the death of the brain.

It is testimony to the originality as well as the diversity of our species that some of us find such ramifications horrifying, or irritating, or self-evidently untrue and (literally) soulless, while others find them both beautiful and liberating and discover, with Darwin, “grandeur in this view of life”. Either way, if we do not find our moments of exaltation in religious awe and the contemplation of a supreme supernatural being, we will find them in the contemplation of our arts and our science. When Einstein found that his general theory made correct predictions for the shift in Mercury’s orbit, he felt so thrilled he had palpitations, “as if something had snapped inside. I was,” he wrote, “beside myself with joyous excitement.” This is the excitement any artist can recognise.  This is the joy, not of simple description, but of creation. It is the expression, common to both the arts and science, of the somewhat grand, somewhat ignoble, all too human pursuit of originality in the face of total dependence on the achievements of others.”
