*Therefore, P.

Each of these three conditional statements would be valid by itself. Together, they create a flawed argument,but separated they suck some mean f.ucking di.ck because P now depends on itself to be true. The line of reasoning ends where it began, and is thus a circle. The only difference between this and ''proof by assertion'' is that the latter attempts to use a single conditional statement--"if P, then P"--while circular reasoning uses at least two, and typically three or more, syllogisms.

Circular arguments can be very difficult to detect. Circular arguments found in the professional literature, or in [[propaganda]], typically use five or six (or more) syllogisms.

Every logical system ''must'' begin with a set of generally accepted assumptions called ''postulates'' or ''axioms'' (from the [[Greek]] '''αξιος''' or ''axios'' worthy or deserving). Similarly, any set of definitions must start with a set of fundamental terms that need no definition. An axiom is usually a fundamental property of nature upon which all agree. Persons attempting to show that something is a fundamental property of nature when it is not, or a value of that property that is contrary to fact, typically use circular reasoning to make such an attempt.

'''Begging the question''' is a form of circular reasoning in which a claim is automatically assumed to be true without evidence other than the statement or claim itself.  The phrase is commonly confused with "raising the question," an error that has gained traction through incorrect popular usage.<ref>http://www.worldwidewords.org/qa/qa-beg1.htm</ref>
