Scientism, broadly speaking

This, then, is what I mean by Scientism. It is not merely the misapplication of techniques such as quantification to questions where numbers have nothing to say; not merely the confusion of the material and social realms of human experience; not merely the claim of social researches to be applying the aims and procedure of natural science to the human world. Scientism is all of these, but something profoundly more. It is the desperate hope, and wish, and ultimately the illusory belief that some standardized set of procedures called “science” can provide us with an unimpeachable source of moral authority, a suprahuman basis for answers to questions like “What is life, and when, and why?” “Why is death, and suffering?” “What is right and wrong to do?” What are good and evil ends?” “How ought we to think and feel and behave?” It is Scientism on a personal level when one says, as President Reagan did, that he personally believes that abortion is wrong but we must leave it to science to tell us when a fetus enters life. It is Scientism on a cultural level when no scientist rises to demur, when no newspaper prints a rebuttal on its “science” pages, when everyone cooperates, willfully or through ignorance, in the perpetuation of such an illusion. Science can tell us when a heart begins to beat, or movement begins, or what are the statistics on the survival of neonates of different gestational ages outside the womb. But science has no more authority than you do or I do to establish such criteria as the “true” definition of “life” or of human state or of personhood. Social research can tell us how some people behave in the presence of what they believe to be legitimate authority. But it cannot tell us when authority is “legitimate” and when not, or how we must decide, or when it may be right or wrong to obey. To ask of science, or expect of science, or accept unchallenged from science the answers to such questions is Scientism.
