“On October 22, 1996, the New York Times ran an unusual front-page story. Entitled ‘Indian Tribes’ Creationists Thwart Archaeologists,’ it described a conflict that had arisen between two views of where Native American populations originated. According to the standard, extensively-confirmed archaeological account, humans first entered the Americans from Asia, crossing the Bering Strait some 10,000 years ago. By contrast, some Native American creation myths hold that native peoples have lived in the Americas ever since their ancestors first emerged onto the earth from a subterranean world of spirits.”
Is one of these two accounts true, or do they stem from two equally valid ways of knowing? Is the subterranean passage just as real for the traditional Zuni people as the Bering passage is for modern archaoeologists? Is it symptomatic of Western hegemony to impose its totalizing scientific worldview on every culture it encounters?
These are the sorts of questions that philosopher Paul Boghossian explores in Fear of Knowledge: Against Relativism and Constructivism, a book recommended to me by someone whom a news reporter might describe as a reliable source. Boghossian systematically explores and critiques what he calls
“the doctrine of Equal Validity: “There are many radically different, yet ‘equally valid’ ways of knowing the world, with science being just one of them.”
Speaking personally, I accept and embrace the fact that there are many ways of knowing the world, including personal observation, interpersonal relationships, literature and film, and direct manipulation of the stuff that comprises the world. But I also privilege science as the closest thing to objective knowledge about the world that’s on offer. Psychology was my field of study in school. I did some training as a therapist, but mostly I learned how to conduct empirical research. Though its subject matter overlaps considerably with sociology and the humanities, the practice of academic psychology has more in common with biology and chemistry. Psychologists do science. Flights of theory and rhetoric are reserved for the superstars and the emeriti; everyone else is expected to stick closely to the data.
Scientists believe that they’re discovering truths about the world. Sure, they’ve heard of Kuhn: they’re aware that biases can affect results and funding and professional status. But human perception is biased too: that’s why you need carefully calibrated observational tools and measurement instruments and data-analytic techniques. Good technique includes being aware of the biases that might affect your results and either eliminating, controlling, or compensating for them. Someone might come along after you’ve completed your study and identify another bias that you missed. So you try again, tightening up the methods, cleaning up the data, generating results that are just a little bit purer, a little closer to the ideal of objectivity.
I certainly didn’t learn about social constructivism in my graduate education. When eventually I did become exposed to this sort of thinking I regarded it as both insightful and intuitively obvious. Of course worldviews and moralities and tastes aren’t discovered; they’re created by people. And I also thought: that’s why science is so valuable — the method exposes and controls for sociocultural biases as well as perceptual and cognitive ones.
Boghossian, though, contends that the prevailing view in contemporary humanities and social sciences is that
“the truth of a belief is not a matter of how things stand with an ‘independently existing reality;’ and its rationality is not a matter of its approval by ‘transcendent procedures of rational assessment.’ …All knowledge, it is said, is socially dependent because all knowledge is socially constructed.”
Many if not most scientists would agree that they “construct” theories to explain their empirical findings, and that there is a “social” component to establishing consensus within the discipline about whether theory A is better than theory B. But that’s a far cry from saying that scientific knowledge itself is a social construct. Knowledge is discovered. Theories are constructed to explain this knowledge, but the adequacy and general acceptance of a theory always depends on whether that theory accounts adequately for reliable observations of the real world.
Maybe it’s because I trained and worked as a scientist that I find realist ontologies and epistemologies generally more persuasive than social constructivism when it comes to scientific knowledge about the world. Boghossian asserts that analytical philosophers tend also to subscribe to scientific realism, a contention confirmed by a recent survey of Anglophone philosophy departments. Presumably realism strikes a more radical chord among social scientists, humanities scholars, and continental philosophers.
Since part of what I’ve gotten out of blogging is a greater familiarity with just this crowd, I’ve felt more inclined to consider the arguments against realism than is my ordinary inclination. And I don’t deny my naivety regarding much of the sophisticated sociocultural theorizing that identifies systematic bias in the whole scientific enterprise. Still, when I read a book like Boghossian’s, even though it’s a work of philosophy rather than science, I feel like I’m in my element. Here’s the last paragraph:
“The intuitive view is that there is a way things are that is independent of human opinion, and that we are capable of arriving at belief about how things are that is objectively reasonable, binding on anyone capable of appreciating the relevant evidence regardless of their social or cultural perspective. Difficult as these notions may be, it is a mistake to think that recent philosophy has uncovered powerful reasons for rejecting them.”
It’s nicely done, Boghossian’s book. I’m not going to work through his arguments in favor of scientific realism, most of which I find persuasive. Perhaps the book’s biggest weakness is that it doesn’t really explore the extent to which human empirical observations of the real might not correspond with or accurately represent or describe the real itself. For that matter, in my view the book doesn’t adequately describe or debunk the sort of epistemological stance whereby tradition or faith trumps empiricism and reason; e.g., where the Zuni genesis story is deemed true while the anthropologists’ story is false. These gaps are understandable, since Boghossian maintains a sharp focus on critiquing postmodern relativist hermeneutics. And the book is only 130 pages long, so it can’t cover everything.
That said, I still find constructivist theories of knowledge quite exotic when compared with scientific realism. So too with some of the more speculative variants of realism. I think they all have a prominent role to play in contemporary speculative fiction.
