Ulogiske

Ulogiske is a Norwegian adjective form used to describe statements, arguments, or conclusions that lack logical coherence or contradict established principles of reason. In everyday language, it is often employed to critique reasoning that appears inconsistent, unfounded, or irrational.

Etymology and form: the word derives from logisk (logical) with the negative prefix u-, yielding ulogisk (illogical). The form ulogiske is the plural, used before plural nouns or in predicate position after a plural subject (for example: Disse påstandene er ulogiske). The base adjective remains ulogisk in singular contexts and shifts to ulogiske when describing multiple items.

Usage and context: ulogiske is common in philosophy, critical journalism, and debate to flag reasoning that fails to meet criteria of validity, coherence, or evidential support. It may modify nouns directly (ulogiske påstander), appear in predicates (Påstandene er ulogiske), or appear in evaluative discussions of arguments and theories. The term is neutral in itself but often conveys a normative judgment about the quality of reasoning rather than empirical truth.

Relation to related terms: ulogisk is the antonym of logisk (logical), and the concept is closely related to discussions of logical fallacies, sound argumentation, and rational thinking. While primarily used in Norwegian, similar forms exist in Danish, with the same sense, whereas Swedish typically uses different expressions such as or illogisk in everyday language.
