There are two aspects to determining whether an argument is correct. The first is called "material truth" and the second "logical validity". A statement is materially true if it corresponds with some externally observed fact. An argument is logically valid if the conclusions follow from the premises irrespective of the truth of the premisses. Knowing how to construct logically valid arguments and how to spot fallacies in other people's arguments enables one to present one's own point of view coherently and to avoid being misled by fallacious reasoning. Although to judge facts, you need to know the specific sciences pertaining to the facts, as many misleading claims in advertising and political life are based on faulty logic, knowing logic will help you be a better consumer and citizen.
