Logical Fallacy of the Day!

Begging the question (petitio principii) – providing what is essentially the conclusion of the argument as a premise.[22][23][24][25]

Begging the question means "assuming the conclusion of an argument", a type of circular reasoning. This is an informal fallacy where the conclusion that one is attempting to prove is included in an initial premise of an argument, often in an indirect way that conceals this fact.[1]

The term "begging the question" originated in the 16th century as a mistranslation of Latin petitio principii "assuming the initial point".[2] In modern vernacular usage, "to beg the question" is sometimes also used to mean "to raise the question" (as in "This begs the question of whether...") or "to dodge the question".[2] This usage is often proscribed.[3]

History

The original phrase used by Aristotle from which "begging the question" descends is: τ ξ ρχς (or sometimes ν ρχ) ατεν, "asking for the initial thing". The meaning of this to Aristotle is closely tied to the type of dialectical argument he discusses in his Topics, book VIII: a formalized debate in which the defending party asserts a thesis that the attacking party must attempt to refute by asking yes-or-no questions and deducing some inconsistency between the responses and the original thesis. In this stylized form of debate, the proposition that the answerer undertakes to defend is called "the initial thing" (τ ξ ρχς, τ ν ρχ) and one of the rules of the debate is that the questioner cannot simply ask for it (that would be trivial and uninteresting). Aristotle discusses this in Sophistical Refutations and in Prior Analytics book II, (64b, 34–65a 9, for circular reasoning see 57b, 18 – 59b, 1....There's more follow the link.....
 

· Formal Fallacies -A formal fallacy is an error in logic that can be seen in the argument's form.[1]All formal fallacies are specific types of non sequiturs.

· Informal Fallacies are Informal fallacies– arguments that are fallacious for reasons other than structural (formal) flaws and usually require examination of the argument's content.[12]
