Abstract
Still today, and especially today, the question about the relation between faith and knowledge provokes first and foremost religious associations. That this indicates an abridgement of the practice of belief is shown in the case of Jacobi, who definitively shaped the intellectual de-bates at the real beginning of the modern era. Against the still prevailing fideistic misunder-standings of his position, the provocation of a concept of belief is discussed which adheres neither to the belief in revelation nor to the model of philosophical reflection but rather defines a new metaphysics of action. With belief understood as the acceptance of something as true without seeking reasons, day to day living whose reality Jacobi consistently emphasized from the perspective of the acting person rather than from the perspective of the observer, stands at the centre of interest. He thereby frees up the precondition for a new understanding of traditional religious and epistemic world views as visualization or rationalization of non-propositional belief convictions
