Excellent quote. I would add that there is not just institutional factors, but the "other" factors include behaviours codified into us through evolution (in a broad sense) that leave us vulnerable to this sort of ignorance and abuse. By mentioning evolution I am *not* making claims about immutable human nature etc.

The mathematician Doron Zellberger [sp?] writes that the Sokal prank is a cheap laugh at someone's language. There is (to my naive eyes) a sort of wilful reverse language incommensurability going on here with these "theory" or "ideology" analysis thinkers. It seems to me that Chomsky says, as seen even in the limited quotes offered by Jerry, what needs to be said at the theoretical level. It's just that he says it in a particular language (what Jerry calls common sense, and I would agree) that is unpalatable[?] or at least un-parse-able for members of other communities. I think there is a legitimate point to requiring the use of particular language both to avoid pitfalls in inference/analysis and to avoid hidden assumptions and plain old vagueness. However, typically, as long as the alternate language is used honestly and is rich enough (both of which are true of common sense and of Chomsky's usage) then it should be possible to demonstrate the errors of its users in that language itself (I am speaking generally; common sense is heavily tied to very human notions of sense and explanation, whereas some languages such as math can produce internally meaningful sentences that cannot be translated into common sense terms at all. Similar things may be true of poetry though it shares the tokens of common sense language).
For example, Aristotle's long wordy text syllogisms are no different from their formal logical symbolic counterparts. Now, using the symbolic versions gives us two things: one, the possible manipulations of the tokens are better spelled out and catch ignored conditions, and second, because of the syntactic nature of the deductions they can unearth wrong conclusions in the syllogisms. Both results can however be explained in Aristotle's language.
I must confess that I have not read Zizek, other than what has been quoted on this list from his writing.
