DRAFT Uncovering constitutive relevance relations in mechanisms * Alexander Gebharter Abstract: In this paper I argue that constitutive relevance rela- tions in mechanisms behave like a special kind of causal relation in at least one important respect: Under suitable circumstances consti- tutive relevance relations produce the Markov factorization. Based on this observation one may wonder whether standard methods for causal discovery could be fruitfully applied to uncover constitutive relevance relations. This paper is intended as a first step into this new area of philosophical research. I investigate to what extent the PC algorithm, originally developed for causal search, can be used for constitutive relevance discovery. I also discuss possible objec- tions and certain limitations of a constitutive relevance discovery procedure based on PC. * This is a draft paper.
