The Folly of Scientism
Good article The folly of Scientism
While not agreeing with the author’s philosophy, I appreciate his rebuke of Scientism.
These questions include how we define and understand science itself. One group of theories of science — the set that best supports a clear distinction between science and philosophy, and a necessary role for each — can broadly be classified as “essentialist.” These theories attempt to identify the essential traits that distinguish science from other human activities, or differentiate true science from nonscientific and pseudoscientific forms of inquiry. Among the most influential and compelling of these is Karl Popper’s criterion of falsifiability outlined in The Logic of Scientific Discovery (1959).
An additional strength of the falsifiability criterion is that it makes possible a clear distinction between science properly speaking and the opinions of scientists on nonscientific subjects. We have seen in recent years a growing tendency to treat as “scientific” anything that scientists say or believe. The debates over stem cell research, for example, have often been described, both within the scientific community and in the mass media, as clashes between science and religion. It is true that many, but by no means all, of the most vocal defenders of embryonic stem cell research were scientists, and that many, but by no means all, of its most vocal opponents were religious. But in fact, there was little science being disputed: the central controversy was between two opposing views on a particular ethical dilemma, neither of which was inherently more scientific than the other. If we confine our definition of the scientific to the falsifiable, we clearly will not conclude that a particular ethical view is dictated by science just because it is the view of a substantial number of scientists. The same logic applies to the judgments of scientists on political, aesthetic, or other nonscientific issues. If a poll shows that a large majority of scientists prefers neutral colors in bathrooms, for example, it does not follow that this preference is “scientific.”
The fundamental problem raised by the identification of “good science” with “institutional science” is that it assumes the practitioners of science to be inherently exempt, at least in the long term, from the corrupting influences that affect all other human practices and institutions. Ladyman, Ross, and Spurrett explicitly state that most human institutions, including “governments, political parties, churches, firms, NGOs, ethnic associations, families … are hardly epistemically reliable at all.” However, “our grounding assumption is that the specific institutional processes of science have inductively established peculiar epistemic reliability.” This assumption is at best naïve and at worst dangerous. If any human institution is held to be exempt from the petty, self-serving, and corrupting motivations that plague us all, the result will almost inevitably be the creation of a priestly caste demanding adulation and required to answer to no one but itself.
Thus a (largely justifiable) admiration for the work of scientists has led to a peculiar, unjustified role for scientists themselves — so that, increasingly, what is believed by scientists and the public to be “scientific” is simply any claim that is upheld by many scientists, or that is based on language and ideas that sound sufficiently similar to scientific theories.
The Eclipse of Metaphysics
There are at least three areas of inquiry traditionally in the purview of philosophy that now are often claimed to be best — or only — studied scientifically: metaphysics, epistemology, and ethics. Let us discuss each in turn.
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
