- (logic) Either of a pair of propositions, that cannot both be true or both be false.
- 2001, Mark Sainsbury, chapter 1, in Logical Forms — An Introduction to Philosophical Logic, 2nd edition, Blackwell Publishing, →ISBN, §4, page 20:
- If one proposition is the negation of another, it follows trivially from the definition that the two propositions are contradictories. The converse does not hold. Two propositions can be contradictories without either being the negation of the other. For example:
3) John is more than six feet tall
4) John is either exactly six feet tall or else less than six feet tall
are contradictories, but neither is the negation of the other. Negation is one way, but not the only way, of forming a contradictory.
any of a pair of propositions, that cannot both be true or both be false
