Do not look around you to what guides others but look straight at this: Where is Nature leading you? By this I mean both the nature of the Whole which acts upon you, and your own nature which requires action by you. But everyone must do what is in accordance with their constitution, and all other parts of the person have been constituted for the sake of the rational part, just as in every other case the lower exist for the sake of the higher. But rational beings have been made for the sake of each other.
