Non-classical logic

Connexive logic

Connexive logic names one class of alternative, or non-classical, logics designed to exclude the paradoxes of material implication. The characteristic that separates connexive logic from other non-classical logics is its acceptance of Aristotle's thesis, i.e. the formula, * ~(~p → p) as a logical truth. Aristotle's thesis asserts that no statement follows from its own denial. Stronger connexive logics also accept Boethius' thesis, * ((p → q) → ~(p → ~q)) which states that if a statement implies one thing, it does not imply its opposite. Relevance logic is another logical theory that tries to avoid the paradoxes of material implication. (Wikipedia).
