Abstract

This chapter describes the language of law and the different occurrences of the lexical family of lex as part of a very complex terminology which refers to a more complex range of different types and variants. An important laboratory for a first analysis of the concept of law as essential bond of nature is present in the early writings of the philosopher. Spinoza's ‘treaty of method’ outlines a horizon in which mutual relations and relations of mutual dependency between entities are a guarantee of intelligibility and knowledge. The theoretical process marking the introduction of the geometrical order into the human sphere involves the transformation of the law from a system of universal relationships into personal and collective experience according to a path of interior requalification. The particular conception of Spinoza's law would cross the boundary between philosophy and science, for more than a century.
