Pretty hard considering Hegel would not even be born a few decades after Leibniz died. Agreed that it is preferable to the "fallen world" starting point of so many other philosophies. Once you think the world is fallen or broken, the only remaining thing is trying (and waiting ;) ) to bring about some kind of Utopia by changing humankind, nature, etc..
