Logic
Logic (from the Greek λογική, logikē) refers to both the study of modes of reasoning (which are valid and which are fallacious) and the use of valid reasoning. In the latter sense, logic is used in most intellectual activities, including philosophy and science, but in the first sense, is primarily studied in the disciplines of philosophy, mathematics, semantics, and computer science. It examines general forms that arguments may take. In mathematics, it is the study of valid inferences within some formal language. Logic is also studied in argumentation theory.

Famous quotes containing the word logic:
“What avail all your scholarly accomplishments and learning, compared with wisdom and manhood? To omit his other behavior, see what a work this comparatively unread and unlettered man wrote within six weeks. Where is our professor of belles-lettres, or of logic and rhetoric, who can write so well?”
—Henry David Thoreau (18171862)
“The much vaunted male logic isnt logical, because they display prejudicesagainst half the human racethat are considered prejudices according to any dictionary definition.”
—Eva Figes (b. 1932)
“We want in every man a long logic; we cannot pardon the absence of it, but it must not be spoken. Logic is the procession or proportionate unfolding of the intuition; but its virtue is as silent method; the moment it would appear as propositions and have a separate value, it is worthless.”
—Ralph Waldo Emerson (18031882)
