Doesn’t the principle of ‘what is best’ cancel the reality of a divine choix in this world? How is it possible to maintain God’s free choice if God’s will is strictly determined by the infallible judgment of God’s wisdom? Leibniz’s doctrine of God’s freedom never stopped being debated. But scholars have somewhat neglected a corollary possibility: why create something rather than nothing? Does the scolastic distinction between freedom of specification and freedom of exercise apply, in Leibniz’s thinking? This article considers the role of this twofold freedom in Leibniz’s late thinking, around the time of his essay on theodicy, taking into account his doctrine of creation and the divine attributes. This inquiry is significant since it raises two major questions related to the principle of reason and the limit of human reason.
