This article recalls the various manifestations of the anthropomorphic doctrine of the fundamental rights of states with a view to critically examining the various functions of anthropomorphic thinking in international law. This allows the article to provide some critical insights on the remnants of the doctrine of fundamental rights of states and the role played by those anthropomorphic residues in contemporary international law. This article is built on a diachronic examination of the functional changes which the doctrine of fundamental rights of states underwent since its origin. This article, after some introductory considerations on the relations between rights and anthropomorphic thinking, examines how anthropomorphic thinking materialised in the form of a doctrine of fundamental rights of states and came to thrive in international legal thought. The article then turns to the manifestation of the doctrine of fundamental rights of states in the inter-American and United Nations contexts with a view to shedding light on the functions that such positive rules pertaining to the fundamental rights of states were meant to play in the international legal order. The article subsequently discusses the demise of the classical doctrine of fundamental rights of states and the foundering of the codification process in order to examine the role that the remains thereof are meant to play in contemporary international law. It ends with a few concluding remarks on the ubiquity of anthropomorphic thinking about international law. Throughout this examination of the functions of the anthropomorphic doctrine of fundamental rights of states, this article espouses the view that, in contemporary legal argumentation, the notion of fundamental rights of state does not constitute any autonomous construction to which specific legal effects are ascribed but rather a textual package of protest or resistance.
