| Article 195–Absurdity | ||
| Canon 2657 | ||
| An Absurdity is a Result or Conclusion extremely unreasonable so as to be foolish and not to be taken seriously. In reasoning, it is the opposite of seriousness. | ||
 |
||
| Canon 2658 | ||
| Reductio ad absurdum, meaning “reduction to the absurd” is a form of argument in which a proposition is disproved by following its implications logically to an absurd consequence. | ||
|
||
| Canon 2659 | ||
| Proof by contradiction is a method of argument whereby a proposition is proved true by proving that it is impossible for it to be false. For example, if A is false, then B is also false; but B is true, therefore A cannot be false and therefore A is true. In practice (outside of mathematics) such arguments are frequently premised on a false dichotomy making the ostensible proof a logical fallacy. | ||
