If you're interested in English and some of its best-known literature, you may well know of the 'Alice' books by Lewis Carroll (real name: Charles Lutwidge Dogdson) ~ who was in fact a teacher of mathematics and logic at the University of Oxford, about 150 years ago. The books are full of word-play (like the poem 'Jabberwocky') and logical tricks. At one point there is a poem about 'The Walrus and the Carpenter', which begins:'The sun ... ... on the sea, Shining with all his might (...)And this ... ... odd, because it was The middle of the night.'
