Denying the Antecedent (Paperback)

High Quality Content by WIKIPEDIA articles! In philosophy, a formal fallacy or a logical fallacy is a pattern of reasoning which is always wrong. This is due to a flaw in the logical structure of the argument which renders the argument invalid. A formal fallacy is contrasted with an informal fallacy, which may have a valid logical form, but be false due to the characteristics of its premises, or its justification structure. The term fallacy is often used more generally to mean an argument which is problematic for any reason, whether it be a formal or an informal fallacy.
