- n. Proof, either a process of stating in an orderly manner indubitable propositions which evidently cannot be true without the truth of the conclusion so proved, or the propositions so Stated. Properly, demonstration is restricted to perfect proof, especially mathematical proof. (See the extract from Burgersdicius, below.) According to the Aristotelian doctrine, which has greatly influenced the use of the word, demonstration must be drawn from principles not only self-evident, but also underived from any higher principles; and the conclusion must not only be shown to be true, but also to be a mere special case of the truth of one or more of the principles from which it is derived. It was supposed that this was the character of the best mathematical proofs; but mathematical proof consists in constructing a diagram or formula according to certain rules which prescribe that certain relations shall exist between the parts of that diagram, and then in showing by observation (directly or indirectly) that certain additional relations exist between those parts; and no important mathematical proof is of the nature of the Aristotelian demonstration. The word has consequently acquired two significations: first, its original sense of a perfect mathematical proof; second, the sense of a proof drawn from principles, as in the Aristotelian theory. There is also a third signification, according to which a demonstration is any proof which leaves no room for reasonable doubt, such as Kepler's proof that the orbit of Mars is an ellipse. Writers who adopt the Aristotelian view hold that the reductio ad absurdum and the Fermatian mode of proof, though entirely convincing, are not perfect demonstrations.
- n. In Roman law, the formal statement of the plaintiff's claim in presenting his case to the court: somewhat analogous to the ‘declaration’ of the common law.
