Logic (from the Greek λογική, logikē)1 refers to both the study of modes of reasoning (which are valid and which are fallacious)2 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.3 Logic is also studied in argumentation theory.4
Logic was studied in several ancient civilizations, including India,5 China,6 and Greece. In the west, logic was established as a formal discipline by Aristotle, who gave it a fundamental place in philosophy. The study of logic was part of the classical trivium, which also included grammar and rhetoric.
Logic is often divided into three parts, inductive reasoning, abductive reasoning, and deductive reasoning.

Get the loginfo mug.A warped method of reasoning and debate technique encountered primarily in the pub, whereby common sense and prior knowledge are overused at the expense of actual evidence and synopticity, caused mainly by alcohol intoxication.

Get the quito logic mug.Junkie logic is the logic used by junkies. It has several characteristics that distinguish it from normal logic. These include: a reliance on irrelevant information to support an argument, combining multiple unrelated assertions, and jumping to conclusions not based on fact or reality. Junkie logic is often self-serving, and the user can rationalize away even the most convincing evidence against them.
Max: "Hey James, I know you said that the world is round, but maybe that's just because it's from your perspective. I mean, from my perspective, it's all relative, you know? It's like, if I think that the world is flat, then it's flat. But if I think it's round, it's round. So you can't really say whether it's flat or round, it just depends on which on you choose."
James: "Man, get out of here with that junkie logic."
