Human Events, the right-wing weekly, has posted its list of the Ten Most Harmful Books of the 19th and 20th Centuries, as chosen by "a panel of 15 conservative scholars and public policy leaders," many of them associated with mainstream institutions.
There are a bunch of the usual suspect-authors here: Marx, Hitler, Mao, John Maynard Keynes, etc. However, congratulations go out to John Stuart Mill (On Liberty got an Honorable Mention!), John Dewey (why is Democracy and Education the fifth Most Harmful Book? Because it "helped nurture the Clinton generation"), and Charles Darwin (two separate Honorable Mentions for writing two different Most Harmful Books). And yes, Auguste Comte positively made the list.
