A Cult Of Ignorance, Isaac Asimov

It's hard to quarrel with that ancient justification of the free press: "America's right to know." It seems almost cruel to ask, ingeniously, "America's right to know what, please? Science? Mathematics? Economics? Foreign languages?"

None of those things, of course. In fact, one might well suppose that the popular feeling is that Americans are a lot better off without any of that tripe.

  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
