Abstract

This article is divided into introduction andd three section. In the first section we examine Leibniz’ termini necesitas-possibilitas. In the second section we propose a minimal modal logic, LLM, arise from the addition of modal priciples. Finally in the last section we examine his complex studie towards the interpretation of modal language in the possible worlds. The resulting interplay between the minimal modallogic and the possible worlds perspective is one of the main charms of semantics.
