What is Scientism?
A scientist, my dear friends, is a man who foresees; it is because science provides the means to predict that it is useful, and the scientists are superior to all other men.
–Henri de Saint-Simon
Scientism is a rather strange word, but for reasons that we shall see, a useful one. Though this term has been coined rather recently, it is associated with many other “isms” with long and turbulent histories: materialism, naturalism, reductionism, empiricism, and positivism. Rather than tangle with each of these concepts separately, we’ll begin with a working definition of scientism and proceed from there.
Historian Richard G. Olson defines scientism as “efforts to extend scientific ideas, methods, practices, and attitudes to matters of human social and political concern.”1 But this formulation is so broad as to render it virtually useless. Philosopher Tom Sorell offers a more precise definition: “Scientism is a matter of putting too high a value on natural science in comparison with other branches of learning or culture.”2 MIT physicist Ian Hutchinson offers a closely related version, but more extreme: “Science, modeled on the natural sciences, is the only source of real knowledge.”3 The latter two definitions are far more precise and will better help us evaluate scientism’s merit.
A HISTORY OF SCIENTISM
The Scientific Revolution
The roots of scientism extend as far back as early 17th century Europe, an era that came to be known as the Scientific Revolution. Up to that point, most scholars had been highly deferent to intellectual tradition, largely a combination of Judeo-Christian scripture and ancient Greek philosophy. But a torrent of new learning during the late Renaissance began to challenge the authority of the ancients, and long-established intellectual foundations began to crack. The Englishman Francis Bacon, the Frenchman Rene Descartes, and the Italian Galileo Galilei spearheaded an international movement proclaiming a new foundation for learning, one that involved careful scrutiny of nature instead of analysis of ancient texts.
Descartes and Bacon used particularly strong rhetoric to carve out space for their new methods. They claimed that by learning how the physical world worked, we could become “masters and possessors of nature.”4 In doing so, humans could overcome hunger through innovations in agriculture, eliminate disease through medical research, and dramatically improve overall quality of life through technology and industry. Ultimately, science would save humans from unnecessary suffering and their self-destructive tendencies. And it promised to achieve these goals in this world, not the afterlife. It was a bold, prophetic vision.
As this new method found great success, the specter of scientism began to emerge. Both Bacon and Descartes elevated the use of reason and logic by denigrating other human faculties such as creativity, memory, and imagination. Bacon’s classification of learning demoted poetry and history to second-class status.5 Descartes’ rendering of the entire universe as a giant machine left little room for the arts or other forms of human expression. In one sense, the rhetoric of these visionaries opened great new vistas for intellectual inquiry. But on the other hand, it proposed a vastly narrower range of which human activities were considered worthwhile.
A century later, many of the Enlightenment intellectuals continued their love-affair with the power of natural science. They claimed that not only could science enhance the quality of human life, it could even promote moral improvement. The Encyclopedist Denis Diderot aimed to collect, organize, and preserve all human knowledge so that “our children, becoming better instructed, may become at the same time more virtuous and happy.”6 Many of the French philosophers even claimed that science could be a substitute for religion. In fact, during the French Revolution, numerous Catholic churches were converted into “Temples of Reason” and held quasi-religious services for the worship of science.7
The 19th century witnessed the most powerful and enduring formulation of scientism, a system called positivism. Its founder was August Comte, who built his positive philosophy from a deep commitment to David Hume’s empiricism and skepticism. Comte claimed that the only valid data is acquired through the senses. Nothing was transcendent, and nothing metaphysical could have any claim to validity8. The task of scientists was twofold—first, to demonstrate how all phenomena, including human behavior, are subject to invariable natural laws9. Second, they would reduce these natural laws to the smallest possible number, and ultimately unify them under the laws of physics10.
Comte also had a clear sense of the trajectory of intellectual history, which he called The Law of Three Stages: Each branch of knowledge passes through three stages: the theological or fictitious, the metaphysical or abstract, and lastly the scientific or positive state. He believed that through the continual advancement of human understanding, religion would fade away, philosophy and the humanities would be transformed into a naturalistic basis, and all human knowledge would eventually become a product of science. Any ideas outside that realm would be pure fantasy or superstition.
Positivism did not lose its appeal in the 20th century. To the contrary, a group known collectively as The Vienna Circle reinvigorated the fundamental tenets of positivism with enhanced symbolic logic and semantic theory. They called their approach, fittingly, logical positivism. In this system, there are only two kinds of meaningful statements: analytic statements (including logic and mathematics), and empirical statements, subject to experimental verification. Anything outside of this framework is an empty concept.11
Given its sweeping claims, logical positivism came under heavy scrutiny. Karl Popper pointed out that few statements in science can actually be completely verified. However, a single observation has the potential to invalidate a hypothesis, and even an entire theory. Therefore, he proposed that instead of experimental verification, the principle of falsifiability should demarcate what qualified as science, and by extension, what can qualify as knowledge.12
Another weakness of the positivist position is its reliance on a complete distinction between theory and observation. Observations, essential to the empirical approach of science, were claimed by positivists to be brute facts which one could use to establish, evaluate, and compare the theories. However, W.O. Quine pointed out in his “Two Dogmas of Empiricism” that observations themselves are partly shaped by theory (“theory-laden”).13 What counts as an observation, how to construct an experiment, and what data you think your instruments are collecting—all require an interpretive theoretical framework. This realization does not deal a death-blow to the practice of science (as some post-modernists like to claim), but it does undermine the positivist claim that science rests entirely on facts, and is thus an indisputable foundation for knowledge.
SCIENTISM OF TODAY
Scientism today is alive and well, as evidenced by the statements of our celebrity scientists:
“The Cosmos is all that is or ever was or ever will be.” –Carl Sagan, Cosmos
“The more the universe seems comprehensible, the more it also seems pointless.” –Stephen Weinburg, The First Three Minutes
“We can be proud as a species because, having discovered that we are alone, we owe the gods very little.” –E.O. Wilson, Consilience
While these men are certainly entitled to their personal opinions and the freedom to express them, the fact that they make such bold claims in their popular science literature blurs the line between solid, evidence-based science, and rampant philosophical speculation. Whether one agrees with the sentiments of these scientists or not, the result of these public pronouncements has served to alienate a large segment of American society. And that is a serious problem, since scientific research relies heavily upon public support for its funding, and environmental policy is shaped by lawmakers who listen to their constituents. From a purely pragmatic standpoint, it would be wise to try a different approach.
Physicist Ian Hutchinson offers an insightful metaphor for the current controversies over science:
“The health of science is in fact jeopardized by scientism, not promoted by it. At the very least, scientism provokes a defensive, immunological, aggressive response from other intellectual communities, in return for its own arrogance and intellectual bullyism. It taints science itself by association.”14
Noting that most Americans enthusiastically welcome scientific advancements, particularly those in health care, transportation, and communications, Hutchinson suggests that perhaps what the public is rejecting is not actually science itself, but a worldview that closely aligns itself with science—scientism15. By disentangling these two concepts, we have a much better chance for enlisting public support for scientific research than we would by trying to convince millions of people to embrace a materialistic, godless universe in which science is our only remaining hope.
DISTINGUISHING SCIENCE FROM SCIENTISM
So if science is distinct from scientism, what is it? Science is an activity that seeks to explore the natural world using well-established, clearly-delineated methods. Given the complexity of the universe, from the very big to very small, from inorganic to organic, there is a vast array of scientific disciplines, each with its own specific techniques. The number of different specializations is constantly increasing, leading to more questions and areas of exploration than ever before. Science expands our understanding, rather than limiting it.
Scientism, on the other hand, is a speculative worldview about the ultimate reality of the universe and its meaning. Despite the fact that there are millions of species on our planet, scientism focuses an inordinate amount of its attention on human behavior and beliefs. Rather than working within carefully constructed boundaries and methodologies established by researchers, it broadly generalizes entire fields of academic expertise and dismisses many of them as inferior. With scientism, you will regularly hear explanations that rely on words like “merely”, “only”, “simply”, or “nothing more than”. Scientism restricts human inquiry.
It is one thing to celebrate science for its achievements and remarkable ability to explain a wide variety of phenomena in the natural world. But to claim there is nothing knowable outside the scope of science would be similar to a successful fisherman saying that whatever he can’t catch in his nets does not exist16. Once you accept that science is the only source of human knowledge, you have adopted a philosophical position (scientism) that cannot be verified, or falsified, by science itself. It is, in a word, unscientific.
