Now suppose (by way of a reductio assumption) that d and s were commensurable in terms of a common unit u, so that d n x u and s m x u, where m and n are whole numbers (integers) that have no common divisor. (If there were a common divisor, we could simply shift it into.) Now we know that ( n x u ) 2( m x u ) we then have it that n. This means that n must be even, since only even integers have even squares. So n. But now n (2 k ) 4 k 2 m, so that 2. But this means that m must be even (by the same reasoning as before).
Such argumentation is in effect simply an implementation of the above-stated principle with p standing in place. As this line of thought indicates, reductio argumentation is a special case of demonstrative reasoning. What we deal with here is an argument of the pattern: From the situation (to-be-refuted assumption a conjunction of preestablished facts) contradiction one proceeds to conclude the denial of that to-be-refuted assumption via modus tollens argumentation. An example my help to clarify matters. Consider division by zero. If this were possible when x is not 0 and omgevingsvergunning we took x 0 to constitute some well-defined quantity q, then we would have x 0 q so that x 0 x Q so that since 0 x (anything) 0 we would have. The supposition that x 0 qualifies as a well-defined quantity is thereby refuted. A classical Example of Reductio argumentation A classic instance verwijderen of reductio reasoning in Greek mathematics relates to the discovery by pythagoras - disclosed to the chagrin of his associates by hippasus of Metapontum in the fifth century bc - of the incommensurability of the diagonal. The reasoning at issue runs as follows: Let d be the length of the diagonal of a square and s the length of its sides. Then by the pythagorean theorem we have it that d.
theses (that is, doctrines or positions or teachings) modes of reasoning or argumentation definitions instructions and rules of procedure practices, policies. The logic of Strict Propositional Reductio: Indirect Proof Whitehead and Russell in Principia mathematica characterize the principle of " reductio ad absurdum " as tantamount to the formula ( p p ) p of propositional logic. But this view is idiosyncratic. Elsewhere the principle is almost universally viewed as a mode of argumentation rather than a specific thesis of propositional logic. Propositional reductio is based on the following line of reasoning: If p p, then p Here represents assertability, be it absolute or conditional (that is, derivability). Since p q yields p q this principle can be established as follows: Suppose (1) p p (2) p p from (1) (3) p ( p p ) from (2) since p p (4) ( p p ) p from (3) by contraposition (5) (. The reasoning involved here provides the basis for what is called an indirect proof. This is a process of justificating argumentation that proceeds as follows when the object is to establish a certain conclusion p : (1) Assume not- p (2) Provide argumentation that derives p from this assumption. (3) maintain p on this basis.

This takes three principal forms according as that untenable consequence is: a self-contradiction ( ad absurdum ) a falsehood ( ad falsum or even ad impossible ) an implausibility or anomaly ( ad ridiculum or ad incommodum the first of these is reductio ad absurdum. Some conditionals that instantiate this latter sort of situation are: If that's so, then I'm model a monkey's uncle. If that is true, then pigs can fly. If he did that, lange then I'm the Shah of Persia. What we have here are consequences that are absurd in the sense of being obviously false and indeed even a bit ridiculous. Despite its departure from what is strictly speaking so construed - conditionals with self-contradictory - time to time conclusions this sort of thing is also characterized as an attenuated mode of reductio. But while all three cases fall into the range of the term as it is commonly used, logicians and mathematicians generally have the first and strongest of them in view.

Reductio ad absurdum is a mode of argumentation that seeks to establish a contention by deriving an absurdity from its denial, thus arguing that a thesis must be accepted because its rejection would be untenable. It is a style of reasoning that has been employed throughout the history of mathematics and philosophy from classical antiquity onwards.
