FREGE AND ŁUKASIEWICZ ON LOGICAL VALUES

Gottlob Frege and Jan Łukasiewicz. We are especially focused on the
problem of logical values and their ontological interpetation. The paper is

Our article regards the connections between the views on semantics of
Gottlob Frege and Jan Łukasiewicz. We are especially focused on the
problem of logical values and their ontological interpetation. The paper is
composed of three parts. In the first section we point out the general
tendencies in the reception of Frege’s logical theory in the Lvov-Warsaw
Philosophical School. The second section is dedicated to Frege’s semantics,
especially his analysis of sense and meaning of propositions. In the third
section we reconstruct Łukasiewicz’s propositional semantics from the
period when he was inspired by Frege’s semantics. We also critically
examine the widespread opinion, according to which the ontological
interpretation of logical values proposed by Łukasiewicz is entirely
consistent with Frege’s concept.
