<p>Point:</p>
<p>(1) In most academic departments, most of the time, "intellectual diversity," understood as balance in political identification, is simply irrelevant. As Brian Leiter observes, "in the overwhelming majority of academic disciplines political identification barely matters, as compared to technical skill and ability. Consider: classics, philosophy, physical anthropology, chemistry, computer sciences, mathematics, archaeology, physics, astronomy, engineering, linguistics, biology, psychology, sociology, even (in large part) economics." While I would question at least four of the entries on Leiter's list, his basic point is right. Political identification simply doesn't (or shouldn't) matter in mathematics and the hard sciences (at least). Of course, neither does (nor should) sexual, racial or ethnic identity - but that's another story.</p>
<p>I disagree about whether intellectual diversity matters as far as classics, philosophy, archaeology, and physical anthropology--intellectual diversity would be more important in those classes-- but I feel that the author's point is valid. More or less, intellectual diversity doesn't even matter much. How many ways are there for an engineer to approach a problem? Now how more likely is he to use a certain thinking pattern just because he's a liberal? Exactly. Of course the same can be said for other sorts of identity but so what? Are conservatives underrepresented in college? Not really. Conservative students attend majority conservative schools; liberal students attend liberal schools. If you want a mixture of both attend a large university. The same applies for anyone looking for any sort of "intellectual diversity". The answer lies in the big university. You're bound to find someone that thinks differently than you do.</p>
<p>And the most important point, perhaps is this...</p>
<p>2) In such departments and at such times as "intellectual diversity" is relevant, it is also relative to the eye of the beholder. In a discussion of political philosophy, for example, my idea of "diversity" might be to include a Christian natural law theorist, a secular traditionalist, a libertarian anarcho-capitalist, a Rawlsian liberal and a left communitarian. But to someone whose idea of "diversity" was a Leninist, a Trotskyite, a Maoist, a Frankfurt Schooler and a feminist psychoanalyst, my list would no doubt look impossibly narrow - and the feeling would be mutual. Moreover, neither of us might feel any need to include a fascist, a numerologist or an interspecific egalitarian simply to make things more "diverse." There are limits, after all. But what limits? Anyone familiar with the way philosophical arguments go will immediately recognize that there is no hope whatsoever of achieving any consensus at all on how to measure "intellectual diversity" or how to decide which forms of such "diversity" are within reasonable limits and which are not. </p>
