## 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:

“...some sort of false *logic* has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.”

—Ellen Henrietta Swallow Richards (1842–1911)

“You can no more bridle passions with *logic* than you can justify them in the law courts. Passions are facts and not dogmas.”

—Alexander Herzen (1812–1870)

“The American Constitution, one of the few modern political documents drawn up by men who were forced by the sternest circumstances to think out what they really had to face instead of chopping *logic* in a university classroom.”

—George Bernard Shaw (1856–1950)
