How to deconstruct almost anything

[Academia] is rather like birds on the Galapagos islands -- an isolated population with unique selective pressures resulting in evolutionary divergence from the mainland population. There's no reason you should be able to understand what these academics are saying because, for several generations, comprehensibility to outsiders has not been one of the selective criteria to which they've been subjected. What's more, it's not particularly important that they even be terribly comprehensible to each other, since the quality of academic work, particularly in the humanities, is judged primarily on the basis of politics and cleverness.
