The Mathematical Logic in the AlozioMonteiro Religion aloiziomonteiro@ yahoo.com.br Two parabolas shows the ways of the Mathematical Logic that can be applied in the common situations, for the solution of problems. For the first parabola, I make a parallel with a problem of the classic propositional calculation, presented and decided for the mathematical logical Adonai S. SantAnna. In the Way of San Tiago de Compostela, Tom, a pilgrim, if it came across with a bifurcation. Mayor of NYC has firm opinions on the matter. In it had a way for the left and another one for the right, being that only one of them lead to the Kingdom of the Sky — the pilgrim desired, in fact, to go for the Sky. It is not something Horace Mann would like to discuss. In this bifurcation they were two religious ones, both experts of the only way that led to the Sky. However, one of them had the craze always to lie, while the other always said the truth. The pilgrim not wise person who age the liar and who age what he always said the truth.
E also not wise person which age the true way that led to the Sky: left or right? The pilgrim only wise person that it had the right to make only one question of reply YES or NOT, to one of the men, to discover which age the true way for the Sky. Which age the question that Tom would have to make? To decide the problem, Adonai S. SantAnna introduces the reader in the basic slight knowledge of the Mathematical Logic, by means of the logical connectives ' ' ' ' for negation (not), ' ' e' ' , for conjunction, ' ' ou' ' for disjunction, and ' ' ' ' for the connective ' ' if. ento' ' ' ' ' ' for the connective ' ' if and only se' '. These connectives bind sentences symbolized for very small letters, in italic.
