“Logic, n. The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding. The basic of logic is the syllogism, consisting of a major and a minor premise and a conclusion - thus:Major Premise: Sixty men can do a piece of work sixty times as quickly as one man.Minor Premise: One man can dig a post-hole in sixty seconds; Therefore-Conclusion: Sixty men can dig a post-hole in one second.This may be called syllogism arithmetical, in which, by combining logic and mathematics, we obtain a double certainty and are twice blessed.”

“For every crime that comes before him, a judge is required to complete a perfect syllogism in which the major premise must be the general law; the minor, the action that conforms or does not conform to the law; and the conclusion, acquittal or punishment. If the judge were constrained, or if he desired to frame even a single additional syllogism, the door would thereby be opened to uncertainty.”

“Oh, come off your perch!" said the other man, who wore glasses. "Your premises won't come out in the wash. You wind-jammers who apply bandy-legged theories to concrete categorical syllogisms send logical conclusions skallybootin' into the infinitesimal ragbag. You can't pull my leg with an old sophism with whiskers on it.”

“Life is the art of drawing sufficient conclusions from insufficient premises.”

“If you'll excuse a brief history lesson: most people didn't experience 'the sixties' until the seventies. Which meant, logically, that most people in the sixties were still experiencing the fifties--or, in my case, bits of both decades side by side. Which made things rather confusing.”

“The example of a syllogism that he had studied in Kiesewetter's logic: Caius is a man, men are mortal, therefore Caius is mortal, had throughout his whole life seemed to him right only in relation to Caius, but not to him at all.”
