The Game of Logic Lewis Carroll

How much easier it is, when you want to play a Game, to find one Player than twenty-two! At the same time, though one Player is enough, a good deal more amusement may be got by two working at it together, and correcting each other's mistakes. A second advantage, possessed by this Game, is that, besides being an endless source of amusement (the number of arguments, that may be worked by it, being infinite), it will give the Players a little instruction as well. But is there any great harm in that, so long as you get plenty of amusement? Это и многое другое вы найдете в книге The Game of Logic (Lewis Carroll)
