How can we reconcile the evil at work on Earth and the holiness of God who created it? In the Essays on Theodicy on the Goodness of God, the Freedom of Man and the Origin of Evil (1710), Leibniz sets himself the Promethean task of resolving the problem of evil and exonerating God. According to him, torment, suffering and loss are necessary data to be integrated into an overall perspective, a general harmony. It is up to man to free himself from his anthropocentrism and to see the world not only as it is presented to him but as a series of elements which sometimes escape him. Through this doctrine of God's justice, Leibniz gives meaning to evil by affirming that the world as we know it is indeed the best of all possible worlds.
