What is a Fallacy?

Logical Fallacies (common types of errors in reasoning):

Fallacies are broken down into two categories: formal and informal. Formal fallacies are based strictly on the logical formation of an argument (deductive). Informal fallacies, which are the most commonly recognized and easiest to learn, take into account the non-logical content of an argument (inductive); are false for epistemological, dialectical or pragmatic reasons; and typically fall under three categories: relevance, presumption, ambiguity. The first formation of logical fallacies comes to us from Sir Thomas Aquinas and “The Scholastics”.

    Pretty cool to learn that these are the manipulating tools that people use. It is nice to know many of these fallacies to defend yourself against them.
