This article asks whether the two studies by Max Weber that form his Critique of Stammler are by now only marginal to a study of Weber's work, of historical interest only, given that Rudolf Stammler has long since been relegated to almost complete obscurity. Or could they still lead to a better understanding of the thought of Max Weber? This article argues that the Critique of Stammler offers a still‐relevant contribution to sociological reflection, particularly about law, and valuable guidance for distinguishing normative legal orders from empirical ones, and measuring the causal influence of the former on the latter.
