Jerome : "When I applied my heart to see wisdom and work which takes place on earth- for even day or night its eyes see no sleep. And I perceived all the work of God. Indeed man cannot fathom the events that occur under the sun, inasmuch as man tries strenuously to search, but cannot fathom it. And even though a wise man should presume to know, he cannot know it. "He searches for the causes and understanding of the world, why this or that is done, and for what reason the world is steered by good or bad turns of events; why one is born blind and frail, another born healthy and with sight; why one is poor, another rich; why one is of high birth, another inglorious. Nothing else is of use, unless he is tortured in his search, and has an argument instead of anguish, but he does not find what he is looking for. And when he says that he knows, then he has the beginning of ignorance in him, and starts to sink into deeper madness. But he shows later that justice is the cause of all things, why things happen the way they do, but that those causes hide in secret and are not able to be understood by men. — Commentary on Ecclesiastes
