Christian Thomasius claims for himself the label of ‘eclectic philosopher.’ This claim first regards the emancipation of reason from any other authority, which not only allows him to claim new juridical rights but also to determine philosophy as a wisdom-for-the-world. This claim is, however, narrowed by both the limits of scholastic knowledge and the undue generalizations Thomasius finds in it. The claim is intended to make room for belief, and for a faith purified of all philosophical-theological confusion, i.e., for a wisdom-outside-the-world. Despite being an anti-dogmatist and anti-syncretist, Thomasius’ eclectic claim never proved to be—contrary to a common statement—anti-systematic nor anti-religious.
