There is also a reading list of historical texts which produce red flags to RICU. These include Leviathan by Thomas Hobbes, John Locke’s Two Treatises of Government and Edmund Burke’s Reflections on the Revolution in France, as well as works by Thomas Carlyle and Adam Smith. Elsewhere RICU warns that radicalisation could occur from books by authors including C.S. Lewis, J.R.R. Tolkien, Aldous Huxley and Joseph Conrad. I kid you not, though it seems that all satire is dead, but the list of suspect books also includes 1984 by George Orwell.
