Abstract

The purpose of legal theory seems to be a perpetually debated issue among legal scholars. Koskenniemi argues that the history of international legal theory is conditioned by a dialectical movement between a position justifying any given positive law based on the power of states, and a position arguing for a theory of the state where laws are justified only in accordance with certain substantial conditions. According to Lauterpacht there is very little support in Spinoza's political philosophy for a “separate and independent theory of international law”. The chapter aims to contextualize the passages pointed to by Lauterpacht in order to investigate whether such an endeavor may produce an understanding of Spinoza's political philosophy that makes it apt to function as a basis for a practical theory of international law. Lauterpacht's critique of Spinoza's statements on international law hinges on the argument that they deviate from his general explanation of the mechanisms of law‐making.
