A post at the Blog of the American Chesterton Association about G.K. Chesterton’s frequent references to Edward Lear gives me an opportunity to mention that three nonsense related articles of his are on the Bookshelf of nonsenselit.org:

• A Defence of Nonsense (1901)
• Both Sides of the Looking-Glass (1933)
• Humour (1938)

Another essay which promises to be very interesting is “The Two Kinds of Paradox,” London News 11 March 1911 (reprinted in vol. XXIX of the Collected Works. San Francisco: Ignatius Press, 1988). I have not been able to find a copy, but a discussion is available here.
