Writer and logistician Charles Lutwidge Dodgson, better known by his pen name Lewis Carroll (previously), concluded his 1886 The Game of Logic—which challenged readers in an engaging way to parse out Boolean inferences and propositions by means of a table top game that the book instructed players to make—with a chapter subtitled “Thou canst not hit it, hit it, hit it,/Thou canst not hit it, my good man.” Ninety one pairings of seemingly logical premises ensue but there’s no key or solutions to be found, so one is expected to draw his or her own conclusions. Though these aphorisms might be debated at the Mad Hatter’s table, they are also quite poetic and enigmatic.
