Hayek, yes (Nobel Prize, 1974), but the rest: relative lightweights. (I love Lord Monckton, by the way.) Fine people, but in 100 years no one will know those names. Sorry.
The last genuinely conservative intellectual was William F. Buckley, and even he won't make the honor roll of history. Since Darwin, practically all the big names of academe have been associated with the secular-materialist worldview and/or the Revolution in some way. Hegel, Marx, Wells, Freud, Russell, Nietzsche, Wittegenstein, Wilde, Twain, the younger Curies, Oppenheimer, Shapley, von Neumann, Keynes, both Huxleys, Shaw, Sartre, Watson and Crick, Dawkins, Gould, Hawking — hell, even Carl Sagan and Ayn Rand. Up against these names we conservatives have Kipling, Belloc, Chesterton, Kirk, Tolkien, and C.S. Lewis. (Von Neumann converted to Catholicism on his deathbed, but was a materialist for most of his life. Ditto Wilde.) The last heavyweight intellectual on our team was Pasteur — probably the most brilliant man of the 19th Century. Since then, a lot of good people, but no one whose name is likely to ring down the halls of history.
And without firing a shot.
Game, set and match to conservatives.
As far as academe -- self-selection / Gramscian infiltration.
Cheers!
