The idea of using simple steps to overcome obstacles, problems, situations; something a wise and intelligent person uses to avoid making things assumed or implied; knowing the correct thing over the fastest and easiest thing

Something that makes mathematical sense.

Exact reasoning, or knowing what is true and how to know whether it is true.

The by-product of thinking without relying on emotions.

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.

1. The governing force by which the universe is supposed to operate, but doesn't really.

Non-operation is defined in the sense of a computer program having an error in its programming. Sense life has not crashed, we are forced to conclude that the universe operates.

An extremely logical person will attempt to relate every event, emotion, and idea into a universal truth and will probably devote the entirety of their life to this endeavor, possibly to the point of obsession. When they fail utterly they can only say that they did the most logical thing possible.

2. An excuse to ignore the emotions, logic, ability, or worth of others in order to do whatever the hell one wants.
