The principle that laws themselves—the rules that govern reasoning—operate in two modes: absolute laws (principles that hold for all reasoning, in all contexts, for all beings) and relative laws (rules that are valid within particular logical systems, for particular purposes, under particular assumptions). The law acknowledges that some logical laws are truly universal—the law of non-contradiction (something cannot both be and not be in the same sense), the principle of identity (A is A). Other laws are system-relative—the law of excluded middle (every proposition is either true or false) holds in classical logic but fails in intuitionistic logic. The law of absolute and relative laws reconciles the search for universal logical foundations with the observation that different logical systems have different rules. It's the meta-law that governs all other laws.
