Begging the question is a fallacy in which the premise of an argument presupposes the truth of its conclusion; in other words, the argument takes for granted what it's supposed to prove.
In Critical Thinking (2008), William Hughes and Jonathan Lavery offer this example of question-begging: "Morality is very important, because without it people would not behave according to moral principles."
Used in this sense, the word beg means "to avoid," not "ask" or "lead to." Begging the question is also known as a circular argument, tautology, and petitio principii (Latin for "seeking the beginning").
