“When you come to any passage you don't understand, read it again: if you still don't understand it, read it again: if you fail, even after three readings, very likely your brain is getting a little tired. In that case, put the book away, and take to other occupations, and next day, when you come to it fresh, you will very likely find that it is quite easy.”

English author, poet, mathematician, photographer, and Anglican deacon

Lewis Carroll was the pen name of Charles Lutwidge Dodgson, an English writer, poet, mathematician, photographer, and Anglican deacon. He is best known for Alice's Adventures in Wonderland and its sequel, Through the Looking-Glass, both central works of Victorian literature. His writing is marked by wordplay, logic, and fantasy, and he is also remembered for the poems Jabberwocky and The Hunting of the Snark. Those works are often described as literary nonsense, and some of the odd logic in Alice reflects his published interests in mathematical logic.
