Classical Logic (Propositional Calculus)
Classical logic is the standard framework for formal reasoning, founded by Aristotle and formalised in the modern era by Boole, Frege, and Russell. Operating on the laws of identity, non-contradiction, and excluded middle, it provides the logical foundations for mathematics, science, and digital computation — while embodying specific assumptions that quantum mechanics, paraconsistent logic, and other non-classical frameworks have shown to be domain-limited rather than universal.
