Square divided into quadrants for "The Game of Logic" by Lewis Carroll. London: MacMillan and Co., 1887. Second edition
Lewis Carroll wrote this little text to introduce Victorian children to the concepts of logic. He devised a game, the game of logic, which takes place on a square grid divided into four quadrants. A player uses colored markers to diagram the meaning of propositions such as “some cakes are sweet” and “all tigers are fierce.” The game does a decent job of teaching basic logical theory, coming as it does from the author of “Alice in Wonderland” who, along with his whimsical literary interest in nonsense, was a gifted mathematician.
