Jean Bernard Mérian is one of the main representatives of empiricism at the Academy of Berlin. This article seeks to show how Mérian articulates both his critique of systematic metaphysics, which is based on a synthetic method borrowed from mathematics, and his defence of a new philosophical ethos: an academic or eclectic spirit. I point out a relation of interdependence between terms like “empirical,” “academic” and “eclectic” in Mérian, and I examine how the eclectic approach to philosophy provides him with a method for comparing and critiquing the pretensions of philosophical systems, opening up the possibility of an eclectic conception of the history of philosophical debates.
