totuusarvoluokkien
Totuusarvoluokkien, literally translated from Finnish as “truth‑value classes,” refer to the distinct categories of truth values that a logical system can assign to statements. In classical propositional logic the set of truth‑value classes is two: true and false. However, many non‑classical logics employ richer truth‑value algebras. For example, multi‑valued logics such as three‑valued Łukasiewicz logic introduce an intermediate value often interpreted as “unknown” or “undetermined,” while fuzzy logic uses a continuum of truth values between 0 and 1 to capture degrees of truth.
The concept is central to the algebraic study of logics. A logic’s truth‑value algebra determines the semantics
Understanding totuusarvoluokkien enables logicians and computer scientists to design systems that more accurately model real‑world uncertainty,
