 Further, although human actions flow from prior causes that ultimately arise in God and therefore are known to God as metaphysical certainties, an individual's free will is exercised within natural laws, where choices are merely contingently necessary and to be decided in the event by a "wonderful spontaneity" that provides individuals with an escape from rigorous predestination.For Leibniz, "God is an absolutely perfect being".He describes this perfection later in section VI as the simplest form of something with the most substantial outcome (VI).
