 Note, however, that the five main tenets of Leibniz’s pre-established harmony leave room for God’s supernatural causal activity even in the actions of finite substances. In other words, pre-established harmony, in Leibniz’s hands at least, is a form of concurrentism. More of this will be addressed in the section on divine causation, but for now it is enough to say that God’s causal role in the actions of finite substances at the very minimum is to pre-establish the concomitance or conjunction between “causes” and “effects,” without which God’s aim of producing universal and maximum harmony (Monadology §§85ff) would be frustrated.
