This paper reflects on the possible role of legal positivism in (the cognition of) international law and makes three specific points. First, we need positivism, but only to the extent that it is assigned a few very limited functions. This is the idea of reductionism. Second, positivism should be stripped of all the straw men that are commonly attached to it: voluntarism, state-centricism, rigid and static theories of sources, theories of interpretation and techniques of content determination, etc. This is the idea of emancipation. Third, if restricted to one particular function and emancipated from such approximations, legal positivism can prove to be a useful approach to international law that complements — and can be complemented by — other existing approaches, and which, in that sense, does not claim any monopoly on the cognition of international law. This is the idea of ecumenism. Reductionism, emancipation, and ecumenism are the three prerequisites without which it is not possible to make sense of international legal positivism at all, and short of which international legal positivism cannot make sense of our complex world. They simultaneously constitute three steps that ought to be taken in order to move away from the straightjacket of classical legal positivism. The paper says a few words about each of them.
