Just as the soul fills the body, so God fills the world. Just as the soul bears the body, so God endures the world. Just as the soul sees but is not seen, so God sees but is not seen. Just as the soul feeds the body, so God gives food to the world.
There is nothing so charming as the knowledge of literature; of that branch of literature, I mean, which enables us to discover the infinity of things, the immensity of Nature, the heavens, the earth, and the seas; this is that branch which has taught us religion, moderation, magnanimity, and that has rescued the soul from obscurity; to make her see all things above and below, first and last, and between both; it is this that furnishes us wherewith to live well and happily, and guides us to pass our lives without displeasure and without offence.
