Definition:
The central focus of logic is the systematized study of valid and sound reasoning. It
is often particularly interested in the study of the structure of propositions rather
than their actual content. The reasoning studied can be either deductive or inductive,
although studies of logic more often involve
deductive arguments.
One particular type of logic is called modal logic. Modal logic involves the study of the reasoning behind what might be true - that is to say, the study of the reasoning behind different modes of reality. Formal equations in modal logic use operators not found in traditional formal logic. The letter L is used to represent "it is necessary that" and the letter M is used to represent "it is possible that." Thus, (Lp) means "it is necessary that p" and (Mp) means "it is possible that p."

What is the Logic and the Philosophy of Language?
The two fields Logic and the Philosophy of Language are often treated separately, but they are nevertheless close enough that they are presented together here. Logic is the study of methods of reasoning and argumentation, both proper and improper. The Philosophy of Language, on the other hand, involves the study of how our language interacts with our thinking.What is Philosophy?
