Philo Judaeus De Aeternitate Mundi 1

[1] 1 In every uncertain and important business it is proper to invoke God, because he is the good Creator of the world, and because nothing is uncertain with him who is possessed of the most accurate knowledge of all things. But of all times it is most necessary to invoke him when one is preparing to discuss the incorruptibility of the world; for neither among the things which are visible to the outward senses is there anything more admirably complete than the world, nor among things appreciable by the intellect is there anything more perfect than God. But the mind is at all times the governor of the outward sense, and that which is appreciable by the intellect is at all times superior to that which is visible to the outward senses, but those persons in whom there is implanted a vigorous and earnest love of truth willingly undergo the trouble of making inquiries relative to the subordinate things, from that which is superior to and the ruler over them.
