In the increasingly complex conjunction of law and religion, one of the most crucial questions concerns the privileged place of religion among other convictional positions which are protected under Article 9 of the European Convention on Human Rights. This article argues the need for a trans-disciplinary approach to the question of definitions, importing insights from philosophy, sociology of law and neo-pragmatism. The aim is to elucidate the view that defining is both an art (in the discursive construction of its object) and a form of politics (as a regulative technology, through which the actual flux and complexity of human reality is brought under control). The question of what religion is (the ontological question) should be acknowledged as a jurisprudential red herring.
