Aim of the paper is to analyze the conception of the human nature in Vico’s Diritto universale. The main proposal is to understand that Vico had an essential view of human nature intended as animal rationis particeps and that this definition had a foundational role into his jurisprudence book. In fact, in order to understand myths, laws and facts from the past it’s necessary to understand the natural relationship between the human mind and the eternal truth. It is precisely the disproportion between finite and infinite, that by this relationship are united in human beings, that founds the inexhaustible course of history.
