爆炸原理，也叫做“Ex falso quodlibet”或“ex contradictione (sequitur) quodlibet”，是经典逻辑中陈述从矛盾中可以得出任何事物的规则。用更加形式化的术语，从形如 P ∧ ¬P 的任何命题，可以推导出任何任意的 A。 “爆炸”指称接受一个单一的矛盾到一个系统中会导致整体定理的“爆炸”。

除了矛盾平常的一目了然的不真实性之外，这是对在形式系统中不允许 P ∧ ¬P 为真的主要逻辑论证: 在其中任何任意的公式都是定理的系统是平凡的（trivial）。所以爆炸证明了无矛盾律的正当性。

The principle of explosion (Latin: ex falso (sequitur) quodlibet (EFQ), "from falsehood, anything (follows)", or ex contradictione (sequitur) quodlibet (ECQ), "from contradiction, anything (follows)"), or the principle of Pseudo-Scotus, is the law of classical logic, intuitionistic logic and similar logical systems, according to which any statement can be proven from a contradiction. That is, once a contradiction has been asserted, any proposition (including their negations) can be inferred from it.
