Meditation 4.12

12. In these two ways you must always be prepared: the one, only to act as the principle of the royal and law-giving art prescribes for the benefit of mankind; the second, to change your purpose, if some one is there to correct and to guide you away from some fancy of yours. The guidance must, however, always be from a conviction of justice or common benefit ensuing, and what you prefer must be similar, not because it looked pleasant or popular.
