In literature, too, it is not great achievement to memorize what you have read while not formulating an opinion of your own. - Epictetus

Work, therefore to be able to say to every harsh appearance, “You are but an appearance, and not absolutely the thing you appear to be.” And then examine it by those rules which you have, and first, and chiefly, by this: whether it concerns the things which are in our own control, or those which are not; and, if it concerns anything not in our control, be prepared to say that it is nothing to you.

The first and most important field of philosophy is the application of principles such as “Do not lie.” Next come the proofs, such as why we should not lie. The third field supports and articulates the proofs, by asking, for example, “How does this prove it? What exactly is a proof, what is logical inference, what is contradiction, what is truth, what is falsehood?” Thus, the third field is necessary because of the second, and the second because of the first. The most important, though, the one that should occupy most of our time, is the first. But we do just the opposite. We are preoccupied with the third field and give that all our attention, passing the first by altogether. The result is that we lie – but have no difficulty proving why we shouldn’t.

As for us, we behave like a herd of deer. When they flee from the huntsman's feathers in affright, which way do they turn? What haven of safety do they make for? Why, they rush upon the nets! And thus they perish by confounding what they should fear with that wherein no danger lies. . . . Not death or pain is to be feared, but the fear of death or pain. Well said the poet therefore: — Death has no terror; only a Death of shame!
