J.M. Bocheński is considered to be one of the most important polish logicians. His work in this field of research con­sists in applying logics, semiotics and methodology in non-logical field. In Qu’est-ce que l’authorité? Introduction a` la logique de l’autorite, The Logic of religion, On Analogy Bocheński uses, among other things, theory of relations (he lists the properties of binary relations between two elements of the relation of authori­ty; they are: non-reflexive, asymmetric for the same domain and transitive for the same domain), set theory, various ty­pologies (typology of justifications, ty­pology of possibilities of verification, ty­pology of verifier type, typology of expressions), descriptions of semiotic si­tuations, language and metalanguage di­stinction. Examples of the results of this work are: the definition of authority, its distinction between it’s different types, the outline of the fundamental problems associated with religious discourse, the definition of ambiguity, unequivocalness and three types of analogy. These, as well as other results of his research provide a solid foundation for further, technical­ly more advanced studies.
