Abstract

In this paper, I show how Maimon’s method of fic- tions deals with the specific problems raised by one of his skeptical arguments, namely the quid facti. This argument leads Maimon to adopt what is sometimes called a ‘system interpretation’ of the necessity of empirical laws. Since Maimon thinks that transcendental philosophy cannot prove the fact that the categories have objective validity, he infers that hence systematization, and not the catego- ries, is what constitutes the source of necessity in empirical laws. Yet, systemat- ization can only ever yield high probability but never apodictic necessity. Conse- quently, Maimon proposes to understand theoretical philosophy as science that employs and indeed can only employ the method of fictions. Since neither phil- osophical, nor physical laws can claim objective validity, philosophical princi- ples must be understood as useful fictions. Thereby, philosophy engages in a form of modeling-practice that delivers descriptions of the conceptual conditions that would be required for our scientific judgments to be justified.
