«So sage ich gerade das Gegentheil». Da Bolzano a Leibniz (via Feuerbach)

Through the reading of Feuerbach’s 1837 book dedicated to Leibniz, Bolzano grasp the opportunity to write in his philosophical diaries about the differences between Leibniz’s and his own views. This is an important document, as it provides us with a closer look at the relationship between such two great philosophers: while both signifacantly contributed to the very development of logic, in these pages Bolzano focuses rather on what divides them, particularly in the domain of ontology. His aim is to take up and redefine a monadological metaphysics and a speculative physics. This goal is mainly pursued by overcoming the theory of pre-established harmony.
