Sri Aurobindo
Letters on Yoga
4. Reason, Science and Yoga
I think X bases his ideas on the attempt of Jeans, Eddington and other English scientists to thrust metaphysical conclusions into scientific facts; it is necessary that he should appreciate fully 
the objections of more austerely scientific minds to such a mixture. Moreover, spiritual seeking has its own accumulated knowledge which does not depend in the least on the theories or discoveries of science in the purely physical sphere. X’s attempt like that of Jeans and others is a reaction against the illegitimate attempts of some scientific minds in the nineteenth century and of many others who took advantage of the march of scientific discovery to discredit or abolish as far as possible the religious spirit and to discredit also metaphysics as a cloudy verbiage, exalting science as the only clue to the truth of the universe. But I think that attitude is now dead or moribund; the scientists recognise, as you point out, the limits of their sphere. I may observe that the conflict between religion and science never arose in India (until the days of European education) because religion did not interfere with scientific discovery and scientists did not question religious or spiritual truth because the two things were kept on separate but not opposing lines.
