The aim of this course is to study in their logical and ontological implications some basic concepts related to the analysis of language and to a dialectical conception of philosophical inquiry. The first part will examine the Aristotelian conception of language outlined in De interpretatione: the notions of sign, name, proposition, negation and opposition. Then we will examine, in the course of a close reading of book four of the Metaphysics, the principle of contradiction and how it operates within a dialectical discourse that proceeds by means of questions and refutations. In the second part, attention will be paid to Jan Lukasiewicz’ and Nikolai A. Vasil’ev’s criticism of Aristotle and to their proposals for a logic devoid of the principle of contradiction; in particular, we will investigate a theory of imaginary worlds where contradictory objects and the language suitable for these worlds are envisaged. Finally, we will turn our scrutiny to an examination of the role of fiction in logic.

The course will address the following topics in the following order:

The relationship between language, thought and the world in the De interpretatione.

The elements of the proposition and the relationships of opposition between propositions in the De interpretatione.

The science of being qua being and the principle of contradiction in Metaphysics IV.

The dialectical refutation in Metaphysics IV.

Jan Łukasiewicz’ criticisms of the Aristotelian conception of the principle of contradiction.

The new conception of the proposition and negation in the work of N.A. Vasil’ev.

The imaginary logic for imaginary worlds.
