For the mathematical form of proof by contradiction, see Proof by contradiction.

Reductio ad absurdum (Latin: "reduction to the absurd") is a form of argument in which a proposition is disproven by following its implications to a logical but absurd consequence. It is an argument for which an assumption is shown to be false because it leads to a contradiction (for example a proposition of the form ‘p and not-p’).
