The Folly of Scientism (PDF) (19 pages)
The Thomas Edison quote applies:
Until man duplicates a blade of grass, nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favor compared with the products of nature, the living cell of the plant, the final result of the rays of the sun, the mother of all life.
Comment: Edison was not a Christian, but he did believe in a Supreme being: "I do not believe in the God of the theologians; but that there is a Supreme Intelligence I do not doubt."
