The presented contribution stresses the role of preference ordering and of the logical culture in many spheres of human rational activities, especially in the domains connected with evaluating and decision-making tasks. Since preference relation is conceived as a relation of proposition-like-entities (in the sense of G. H. von Wright), any construction of preference ordering pre_- supposes the application of comparability principles. Preference expressions can be considered as a special form of propositional attitudes and the concept of preference itsself as an intensional operator.
