The Folly of Scientism. Prof. Hughes begins:
When I decided on a scientific career, one of the things that appealed to me about science was the modesty of its practitioners. The typical scientist seemed to be a person who knew one small corner of the natural world and knew it very well, better than most other human beings living and better even than most who had ever lived. But outside of their circumscribed areas of expertise, scientists would hesitate to express an authoritative opinion. This attitude was attractive precisely because it stood in sharp contrast to the arrogance of the philosophers of the positivist tradition, who claimed for science and its practitioners a broad authority with which many practicing scientists themselves were uncomfortable.
The temptation to overreach, however, seems increasingly indulged today in discussions about science. Both in the work of professional philosophers and in popular writings by natural scientists, it is frequently claimed that natural science does or soon will constitute the entire domain of truth.
another quote:
Of all the fads and foibles in the long history of human credulity, scientism in all its varied guises — from fanciful cosmology to evolutionary epistemology and ethics — seems among the more dangerous, both because it pretends to be something very different from what it really is and because it has been accorded widespread and uncritical adherence. Continued insistence on the universal competence of science will serve only to undermine the credibility of science as a whole. The ultimate outcome will be an increase of radical skepticism that questions the ability of science to address even the questions legitimately within its sphere of competence. One longs for a new Enlightenment to puncture the pretensions of this latest superstition.
