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 posthole in sixty seconds; therefore --
Conclusion: Sixty men can dig a posthole in one second.
This may be called the syllogism arithmetical, in which, by combining logic and mathematics, we obtain a double certainty and are twice blessed.
2009 Update: The most analytical form of reason, by which the capable human animal combines two assumptions into one irrelevancy. Logic is never as coldly precise as when it used to explain a failure of judgement, and judgement fails primarily due to distraction and, therefore, the Orange Bowl? Not too shabby.
