Physicist Victor Stenger argues in HuffPo that
Scientists and science organizations are being disingenuous when they say science can say nothing about the supernatural. They know better. Their policy of appeasing religion for presumably political reasons only empowers those who are muddling education and polluting public policy with anti-scientific magical thinking.
Stenger opens with
I find it surprising that most scientists, believers and nonbelievers alike, refuse to apply their critical thinking skills to matters of religion. . . . . Scientists prefer to follow Stephen Jay Gould’s dictum that science and religion occupy two “non-overlapping magisteria.”
That, of course, means individuals are required to leave moral and ethical questions to “scholars who interpret ancient texts.” Provocative Stenger opines that such a situation sounds to him like “Sharia law”. Moral behaviour certainly is observable and a matter of scientific understanding. (It was my own realization that all social animals have “moral codes”, including punishments meted out to those who break them, that helped me on my own journey towards atheism.)
Stenger addresses two (of several) types of scientific experiments that have been conducted to test what should be the observable effects of the supernatural on the natural world: the phenomena of answered — or unanswered — prayer and near-death experiences.
