This is pretty much what I've been attempting to articulate about the state of academia



Really, this guy continues to blow my mind. Although this was written over ten years ago, it is still relevant, as the trendy pomo left (as opposed to the rest of the left, who is unjustly lumped in with them) still continues to have a chokehold on academia. Posting in its entirely.

A Plea for Reason, Evidence and Logic
Alan Sokal
[from New Politics, vol. 6, no. 2 (new series), whole no. 22, Winter 1997]

[Editors' Note: As most of our readers probably know by now, Alan Sokal, a physicist at New York University, submitted a parody of postmodernist studies of natural science to Social Text, which published it as serious contribution in its "Science Wars" issue, Spring/Summer 1996. He then revealed the hoax in the pages of Lingua Franca, producing a wide-ranging debate on the politics of postmodernism and the nature of truth, reason and objectivity. What follows is a transcript of a talk given by Sokal at a forum on that subject held at New York University on October 30, 1996.]

Alan Sokal is a Professor of Physics at New York University. In the summers of 1986-88 he taught mathematics at the Universidad Nacional Autónoma de Nicaragua. He is co-author with Roberto Fernández and Jürg Fröhlich of Random Walks, Critical Phenomena, and Triviality in Quantum Field Theory (Springer, 1992) and co-author with Jean Bricmont of the forthcoming Les impostures scientifiques des philosophes (postmodernes).

THIS AFFAIR HAS BROUGHT UP AN INCREDIBLE NUMBER OF ISSUES, and I can't dream of addressing them all in 10 minutes, so let me start by circumscribing my remarks. I don't want to belabor Social Text's failings either before or after the publication of my parody: Social Text is not my enemy, nor is it my main intellectual target. I won't go here into the ethical issues related to the propriety of hoaxing (although I'm glad to defend my ethics). I won't address the obscurantist prose and the uncritical celebrity-worship that have infected certain trendy sectors of the American academic humanities (though these are important questions that I hope other panelists will address). I won't enter into technical issues of the philosophy of science. I won't discuss the social role of science and technology (though these are important issues). Indeed, I want to emphasize that this affair, in my view, is not primarily about science -- though that was the excuse that I used in constructing my parody -- nor is it a disciplinary conflict between scientists and humanists, who are in fact represented on all sides of the debate. What I believe this debate is principally about -- and what I want to focus on here -- is the nature of truth, reason and objectivity: issues that I believe are crucial to the future of left politics.

I didn't write the parody for the reasons you might think at first. My aim was not to defend science from the barbarian hordes of lit crit or sociology. I know perfectly well that the main threats to science nowadays come from budget-cutting politicians and corporate executives, not from a handful of postmodernist academics. Rather, my goal is to defend what one might call a scientific worldview -- defined broadly as a respect for evidence and logic, and for the incessant confrontation of theories with the real world; in short, for reasoned argument over wishful thinking, superstition and demagoguery. And my motives for trying to defend these old-fashioned ideas are basically political. I am worried about trends in the American Left -- particularly in academia -- that, at a minimum, divert us from the task of formulating a progressive social critique, by leading smart and committed people into trendy but ultimately empty intellectual fashions. These fashions can, in fact, undermine the prospects for such a critique, by promoting subjectivist and relativist philosophies that are inconsistent with producing a realistic analysis of society that we and our fellow citizens will find compelling.

David Whiteis, in a recent article, said it well:

Too many academics, secure in their ivory towers and insulated from the real-world consequences of the ideas they espouse, seem blind to the fact that non-rationality has historically been among the most powerful weapons in the ideological arsenals of oppressors. The hypersubjectivity that characterizes postmodernism is a perfect case in point: far from being a legacy of leftist iconoclasm, as some of its advocates so disingenuously claim, it in fact ... plays perfectly into the anti-rationalist -- really, anti-thinking -- bias that currently infects "mainstream" U.S. culture.

Along similar lines, the philosopher of science, Larry Laudan, observed caustically that the displacement of the idea that facts and evidence matter by the idea that everything boils down to subjective interests and perspectives is -- second only to American political campaigns -- the most prominent and pernicious manifestation of anti-intellectualism in our time. (And these days, being nearly as anti-intellectual as political campaigns is really quite a feat.)

NOW OF COURSE, NO ONE WILL ADMIT TO BEING AGAINST REASON, evidence and logic -- that's like being against Motherhood and Apple Pie. Rather, our postmodernist and poststructuralist friends will claim to be in favor of some new and deeper kind of reason--such as the celebration of "local knowledges" and "alternative ways of knowing" as an antidote to the so-called "Eurocentric scientific methodology" (you know, things like systematic experiment, controls, replication, and so forth). You find this magic phrase "local knowledges" in, for example, the articles of Andrew Ross and Sandra Harding in the "Science Wars" issue of Social Text. But are "local knowledges" all that great? And when local knowledges conflict, which local knowledges should we believe? In many parts of the Midwest, the "local knowledges" say that you should spray more herbicides to get bigger crops. It is old-fashioned objective science that can tell us which herbicides are poisonous to farm workers and to people downstream. Here in New York City, lots of "local knowledges" hold that there's a wave of teenage motherhood that's destroying our moral fiber. It's those boring data that show that the birth rate to teenage mothers has been essentially constant since 1975 and is about half of what it was in the good old 1950s. Another word for "local knowledges" is prejudice.

I am sorry to say it, but under the influence of postmodernism some very intelligent people can fall into some incredibly sloppy thinking, and I want to give two examples. The first comes from a front-page article in the New York Times (10/22/96) about the conflict between archaeologists and some Native American creationists. I don't want to address here the ethical and legal aspects of this controversy -- who should control the use of 10,000-year-old human remains -- but only the epistemic issue. There are at least two competing views on where Native American populations come from. The scientific consensus, based on extensive archaeological evidence, is that humans first entered the Americas from Asia about 10,000-20,000 years ago, crossing the Bering Strait. Many Native American creation accounts hold, on the other hand, that native peoples have always lived in the Americas, ever since their ancestors emerged onto the surface of the earth from a subterranean world of spirits. And the Times article observed that many archaeologists, "pulled between their scientific temperaments and their appreciation for native culture, ... have been driven close to a postmodern relativism in which science is just one more belief system." For example, Roger Anyon, a British archaeologist who has worked for the Zuni people, was quoted as saying that "Science is just one of many ways of knowing the world. ... [The Zunis' world view is] just as valid as the archeological viewpoint of what prehistory is about."

Now, perhaps Dr. Anyon was misquoted, but we all have repeatedly heard assertions of this kind, and I'd like to ask what such assertions could possibly mean. We have here two mutually incompatible theories. They can't both be right; they can't both even be approximately right. They could, of course, both be wrong, but I don't imagine that that is what Dr. Anyon means by "just as valid." It seems to me that Anyon has quite simply allowed his political and cultural sympathies to cloud his reasoning. And there is no justification for that: we can perfectly well remember the victims of a horrible genocide, and support their descendants' valid political goals, without endorsing uncritically (or hypocritically) their societies' traditional creation myths. Moreover, the relativists' stance is extremely condescending: it treats a complex society as a monolith, obscures the conflicts within it, and takes its most obscurantist factions as spokespeople for the whole.

My second example of sloppy thinking comes from Social Text co-editor Bruce Robbins' article in the Sept./Oct. 1996 issue of Tikkun magazine, in which he tries to defend -- albeit half-heartedly -- the postmodernist/poststructuralist subversion of conventional notions of truth. "Is it in the interests of women, African Americans, and other super-exploited people," Robbins asks, "to insist that truth and identity are social constructions? Yes and no," he asserts. "No, you can't talk about exploitation without respect for empirical evidence" -- exactly my point. "But yes," Robbins continues, "truth can be another source of oppression." Huh??? How can truth oppress anyone? Well, Robbins' very next sentence explains what he means: "It was not so long ago," he says, "that scientists gave their full authority to explanations of why women and African Americans ... were inherently inferior." But is Robbins claiming that that is truth? I should hope not! Sure, lots of people say things about women and African Americans that are not true; and yes, those falsehoods have sometimes been asserted in the name of "science," "reason" and all the rest. But claiming something doesn't make it true, and the fact that people -- including scientists -- sometimes make false claims doesn't mean that we should reject or revise the concept of truth. Quite the contrary: it means that we should examine with the utmost care the evidence underlying people's truth claims, and we should reject assertions that in our best rational judgment are false.

This error is, unfortunately, repeated throughout Robbins' essay: he systematically confuses truth with claims of truth, fact with assertions of fact, and knowledge with pretensions to knowledge. These elisions underlie much of the sloppy thinking about "social construction" prevalent nowadays in the academy, and it is something that progressives ought to resist. Sure, let's show which economic, political and ideological interests are served by our opponents' accounts of "reality"; but first let's demonstrate, by marshalling evidence and logic, why those accounts are objectively false (or in some cases true but incomplete).

A bit later in his article, Robbins admits candidly that "those of us who do cultural politics sometimes act as if ... truth were always and everywhere a weapon of the right." Now, that's an astoundingly self-defeating attitude for an avowed leftist. If truth were on the side of the right, shouldn't we all -- at least the honest ones among us -- become right-wingers? For my own part, I am a leftist and a feminist because of evidence and logic (combined with elementary ethics), not in spite of it.

This plea of mine for reason, evidence and logic is hardly original; dozens of progressive humanists, social scientists and natural scientists have been saying the same thing for years. But if my parody in Social Text has helped just a little bit to amplify their voices and to provoke a much-needed debate on the American Left, then it will have served its purpose.

Nice piece. I knew about Sokal but had never actually read anything from the horse's mouth, as it were.

A few reactions:

1 Sokal is a bit unkind in taking aim at the worst kind of post-modernism. There are post-modernists who have some degree of intellectual credibility. Zizek and Derrida, for instance, aren't the sort of people who would just shrug their shoulders and say: "Heck, it's all relative – it's just another language game." They spend time and effort looking at the way language games get misunderstood by those playing them. One favorite tactic, of course, is to look at dualisms (freedom/oppression, truth/lies, self/other) that are assumed to indicate entirely separate "things" and reveal the way the privileged pole of the pair for Derrida and Zizek these very philosophical reflections upon the nature of our language are also supposed to lend weight (somehow) to the very left-wing discourse of emancipation that Sokal wants his science and reason to connect with.

2 On the other hand, the careful and bold readers of Derrida are far, far outnumbered by the flaccid relativists that Sokal attacks. One interesting question here is: how did it come about that there is so much flaccid relativism? Sokal is concerned about this. He implies that it is the fault of certain academics spreading post-modernist ideas. But is it? Is the market outside the academy not a much, much, much more powerful force in undermining the idea of a genuine hierarchy of values – a more powerful force in sapping the will to say "This is genuinely good and that is genuinely bad" – than the activities of a few obscure academics? Is it not that, having experienced and come to accept a general social levelling and the commodification of just about everything, sensitive and somewhat confused and directlonless individuals drift towards the academy and towards ideas about post-modernity because there they find names for what they already inchoately feel? Is the rot in the academy not a symptom of a malaise elsewhere, rather than a cause of it?

3 In the background is a confusion about values. But Sokal needs to acknowledge that the scientific discourse (which of course is brilliant at separating fact from prejudice) has also played a role in contributing to the confusion. The rise of economics as a science, for instance, has been crucial in supporting the idea of the economy as a system that a supposedly democratic society must simply adapt to (the brutal facts of economic life). The values that count in public life are the quantities that can be fed into the relevant scientific equations (inflation, GDP, labour costs, commodity prices, evergy reserves, etc). The rest (worries about meaningful work, the beauty of the environment, the integrity of communities, the vibrancy of the public sphere, etc, etc) are left as personal preferences to be dimly registered in sporadic elections. Could science be used to challenge this marginalisation – this exclusion – of what might really matter to ordinary people when the sort of science that Sokal speaks in defence of insists on the separation of objective facts and (non-objective) values?

Of course, Sokal is not defending JUST science – he also mentions reason, and hopefully there is a way of reasoning about the fate of social life that can do justice to the experience that something is amiss in society above and beyond the regression of thinking in that flaccid thing calling itself post-modernism.

4 I agree with the implication in your title (which Sokal seems to echo) that academia, having been shoved into a position of near total irrelevance by society) ought to engage more vigorously with the wider society (not just in finding funding for research projects) instead of building ever higher and more elaborate ivory towers from which to gaze down on the motley ranks below. Not easy, though, when almost everything else in society promotes a general dumbing down.
