And now how are we to represent the contradictory Proposition "SOME x are m"? This is a difficulty I have already considered. I think the best way is to place a red counter ON THE DIVISION-LINE between No. 11 and No. 12, and to understand this to mean that ONE of the two compartments is 'occupied,' but that we do not at present know WHICH. This I shall represent thus:—

Curioso libro de lógica matemática de Lewis Carroll, a la que era aficionado. Interesante desde el punto de vista histórico.

A mind opener

A local (accredited) university allows a course in Propositional Logic to replace algebra. There is even Propositional Calculus. I find algebra a lot simpler.

Well, this critter is symbolic logic (Mathematical logic) is not the same, but it is close enough. It is more English-orientated.

. Quem diria que o mestre do absurdo era um matemático e um lógico? Mas enfim, para transgredir as regras, será bom conhecê-las a fundo.
. Um livro interessantíssimo para quem gosta de lógica. Tem por exemplo, uma versão gráfica da teoria dos silogismos (que foi o primeiro sistema formal, estabelecid

So clever and entertaining. I am proud to own a physical copy, and it is well loved.

I primi capitoli sono divertenti: la logica proposizionale viene spiegata utilizzando torte ed esempi buffi. Poi però gran parte del libro è dedicata a esercizi e problemini senza fantasia. Peccato!

Carroll's book is an engaging, even playful, introduction to Basic Logic. Especially his diagram method I find particularly illustrative and worth of today's classroom. Also very enlightening is his side-by-side comparison of his method and those of Euclid and Venn. The second book, "The Game of Log

Interesting method for logic thinking, but the publishers note should be taken wholeheartedly as some of the terminology used on the book have aged purely

Genius! Clever. Inspired! Mathematical and wonderful!!! Loved every bit of it!

Stunning, thought-provoking, maddeningly brilliant.

Comprehensive and cleverly written! Having studied symbolic logic before, I cannot speak on the instructive quality for a complete beginner, though I believe I read in Universe in a Handkerchief by Martin Gardner that one of his child friends that he originally wrote The Game of Logic for did not qu
