The bedst perfection does not derive from each indvidual monad's perfection, but It is due to the perfection of the system and order of the universe as a whole . In other words, Under the Divine View-point, all the empirical truths are to be utimately reduced to a priori , analytical truths by means of the principle of sufficient reason. This moral necessity derives from the principle of the better, or the priniciple of sufficient reason. The efficient cause is subordinated to the final cause. The principle of the better is a special case of this principle.
Ratio sufficiens contains both ratio essendi and ratio cogniscendi.
Nothing occurs without any cause or at least something occurs with at least determinant cause. However, this distinction may be meaningfully held from the finite, human point of view. From the Divine Point of View, the principle of sufficient reason ultimately is reducible to the a priori principle of contradiction. The absolute continuity governs the universe. The component members in a series are similar, at the same time The component members in a series are varied.
