Dall' Harmonia Universalis all' Harmonia praestabilita. Evoluzione di un concetto in G.W. Leibniz

The purpose of this work is to prove the presence of an evolution within the concept of harmonia in the leibnitian metaphysical system. That will be done, firstly, by studying the meaning that this notion gain in the early writing of Leibniz (until the Paris years); secondly, by comparing it with the mature concept of pre-established harmony and with the other related issues which are involved in it. With reference to this point, I will face questions referring to relations, to individual substance, to complete concept and finally to the problem of determinism and freedom.
