Remember this: it's not just wanting power and money that makes you weak and dependent on others. Even wanting peace, free time, travel, or education can do the same thing. Here's the truth: whatever outside thing you value highly will make you subject to other people. So what's the difference between wanting to be a senator and not wanting to be one? What's the difference between craving power and being happy with a private life? What's the difference between saying "I'm miserable, I have nothing to do, I'm chained to my books like a dead body" and saying "I'm miserable, I have no time to read"? Because just like praise and power are external things beyond your control, so is a book.
Remember that not only the desire of power and of riches makes us mean and subject to others, but even the desire of tranquillity, and of leisure, and of travelling abroad, and of learning. For, to speak plainly, whatever the external thing may be, the value which we set upon it places us in subjection to others. What then is the difference between desiring to be a senator or not desiring to be one; what is the difference between desiring power or being content with a private station; what is the difference between saying, I am unhappy, I have nothing to do, but I am bound to my books as a corpse; or saying, I am unhappy, I have no leisure for reading? For as salutations and power are things external and independent of the will, so is a book.
