Can Biology do better than Faith?

From the New Scientist

Why does an intense and pervasive resistance to evolution continue 150 years after the publication of On The Origin of Species, and in the teeth of the overwhelming accumulated evidence favouring it? The answer is simply that the Darwinian revolution, even more than the Copernican revolution, challenges the prehistoric and still powerful self-image of humanity. Evolution by natural selection, to be as concise as possible, has changed everything.

In the more than slightly schizophrenic circumstances of the present era, global culture is divided into three opposing images of the human condition. The dominant one, exemplified by the creation myths of the Abrahamic monotheistic religions - Judaism, Christianity and Islam - sees humanity as a creation of God. He brought us into being and He guides us still as father, judge and friend. We interpret His will from sacred scriptures and the wisdom of ecclesiastical authorities.

The second world view is that of political behaviourism. Still beloved by the now rapidly fading Marxist-Leninist states, it says that the brain is largely a blank state devoid of any inborn inscription beyond reflexes and primitive bodily urges. As a consequence, the mind originates almost wholly as a product of learning, and it is the product of a culture that itself evolves by historical contingency. Because there is no biologically based "human nature", people can be moulded to the best possible political and economic system, namely communism. In practical politics, this belief has been repeatedly tested and, after economic collapses and tens of millions of deaths in a dozen dysfunctional states, is generally deemed a failure.

Both of these world views, God-centred religion and atheistic communism, are opposed by a third and in some ways more radical world view, scientific humanism. Still held by only a tiny minority of the world's population, it considers humanity to be a biological species that evolved over millions of years in a biological world, acquiring unprecedented intelligence yet still guided by complex inherited emotions and biased channels of learning. Human nature exists, and it was self-assembled. Having arisen by evolution during the far simpler conditions in which humanity lived during more than 99 per cent of its existence, it forms the behavioural part of what, in The Descent of Man, Darwin called "the indelible stamp of [our] lowly origin".

The inexorable growth of biology continues to widen, not to close, the tectonic gap between science and faith based religion. Rapprochement may be neither possible nor desirable. There is something deep in religious belief that divides people and amplifies societal conflict. The toxic mix of religion and tribalism has become so dangerous as to justify taking seriously the alternative view, that humanism based on science is the effective antidote, the light and the way at last placed before us.

Religions continue both to render their special services and to exact their heavy costs. Can scientific humanism do as well or better, at a lower cost? Surely that ranks as one of the great unanswered questions of philosophy.

So. Can scientific humanism replace faith based religion? Is it a better, safer and more productive way of looking at the world? Or can Humanisn be seen as a 'flash in the pan' soon to be relegated to a footnote in the religious history of the world?
