3. But now having one thing in our power to care for, and to cleave to, we rather choose to be careful of many things, and to bind ourselves to many things, even to the flesh, and to possessions, and to brother and friend, and child and slave. And being thus bound to many things, they lie heavy on us and drag us down. So, if the weather be not fair for sailing, we sit down distraught and are ever peering forth to see how stands the wind. _It is north._ And what is that to us? _When will the west wind blow?_ When it shall seem good to it, friend; or to Æolus. For it was not thee, but Æolus whom God made “steward of the winds.”[2] What then? It is right to devise how we may perfect the things that are our own, and to use the others as their nature is. And what, then, is their nature? As it may please God. CHAPTER IV. THE NATURE OF THE GOOD. 1. The subject for the good and wise man is his own master-faculty, as the body is for the physician and the trainer, and the soil is the subject for the husbandman. And the work of the good and wise man is to use appearances according to Nature. For it is the nature of every soul to consent to what is good and to reject what is evil, and to hold back about what is uncertain; and thus to be moved to pursue the good and to avoid the evil, and neither way towards what is neither good nor evil. For as it is not lawful for the money-changer or the seller of herbs to reject Cæsar’s coin, but if one present it, then, whether he will or no, he must give up what is sold for it, so it is also with the soul. When the Good appears, straightway the soul is moved towards it, and from the Evil. And never doth the soul reject any clear appearance of the good, no more than Cæsar’s coin. On this hangeth every movement both of God and man. 2. The nature and essence of the Good is in a certain disposition of the Will; likewise that of the Evil. What, then, are outward things? Matter for the Will, about which being occupied it shall attain its own good or evil. How shall it attain the Good? Through not being dazzled with admiration of what it works on.[1] For our opinions of this, when right, make the will right, and when wrong make it evil. This law hath God established, and saith, “If thou wouldst have aught of good, have it from thyself.”
