The principle that logic operates within paradigms—that what counts as logical is framework-dependent, that logical systems shift over time and vary across contexts. The Law of Logical Paradigms argues that there is no logic-in-itself, no ultimate logical system; there are only logical paradigms, each adequate to its domain, each limited by its assumptions. Classical logic is one paradigm; intuitionistic logic is another; paraconsistent logic is another. None is the logic; all are logics, each valid within its paradigm. The law doesn't say logic is arbitrary; it says logic is plural, and that the task is to match paradigm to purpose.
Example: "He'd thought there was one logic—the logic, the rules of thought. The Law of Logical Paradigms showed him otherwise: different logics for different purposes, different paradigms for different domains. Classical logic worked for mathematics; paraconsistent logic worked for contradictions; fuzzy logic worked for vagueness. None was the logic; all were tools."
