Logic is the study of the methods and principles used to distinguish good reason from bad reason. Unfortunately it seems to escape most people now a days as they rely on rumors from cnn, emotion and passion.
Me: "without Logic there is no reason. Without reason there is no rationality. Without rationality there is nothing but destruction"

Adolph Hitler (mien Komph) "Propaganda should use very little logic and more emotion and passion to fool the people. Masses are easily fooled by emotion and passion. Thus the more people you are targeting the less logic your propaganda should use" (paraphrased to save space)

A class usually only offered at college that deals with the analysis and appraisal of arguments. There are different systems of logic for different uses, including syllogistic logic (an ancient form of logic dealing with categories), propositional logic (dealing with statements dependence on each other), quantificational logic (a sort of combination of syllogistic and propositional), modal logic (dealing with necessity and possibility), deontic logic and imperative logic (dealing with "can," "should," "will," etc.) and belief logic (dealing with patterns of belief). Most of these systems can be combined with each other and I'm pretty sure there's Wikipedia articles about all of them if you want to know more. Some classes will also cover formalized ethics (building an ethical theory with these previous systems), metalogic (the study of the logical systems themselves) and various forms of reasoning and argumentation.

It is sometimes described as math without numbers, because you learn various formulas to calculate whether or not a statement is true or false in a particular context, but the only numbers you ever see are 0 for false and 1 for true. It is also possibly the worst college course about having people bitch about how hard it is when in reality it's one of the easiest courses you can take.
Imagine a kid with Down's Syndrome handing you a piece of paper with various statements relating to the same thing on it and asking you if they make sense together. If you could handle this, you can handle a logic course. If not, you probably need to take a logic course.
