Logiske

Logiske is a term used in logic and related disciplines to denote a family of non-classical formal systems intended to model reasoning in contexts of incomplete, evolving, or conflicting information. The word blends the English root logic with a Nordic-sounding suffix and is used primarily in theoretical discussions rather than as a single, standardized theory.

Rather than describing one framework, Logiske is typically treated as an umbrella concept that encompasses various approaches to logic emphasizing context-sensitivity and dynamic inference. It draws on elements from paraconsistent logic, which tolerates contradictions; dynamic or context-aware logics, which track how inference conditions change as information is updated; and modal or epistemic logics, which model knowledge and belief states. Core ideas include context-dependent validity, explicit handling of information change, and inference rules that adapt without explosion.

Applications have been explored in artificial intelligence, knowledge representation, natural language processing, and formal verification, especially in settings where information is incomplete or inconsistent. The concept intersects with several other logics, including dynamic logic, nonmonotonic logic, and contextual or epistemic logics; in practice, Logiske serves as a loose umbrella rather than a single formal system.

Critics note the lack of standardized definitions, the risk of fragmentation, and challenges in comparing results across implementations. See also: logic; nonmonotonic logic; paraconsistent logic; dynamic logic; contextual logic.
