## Key lines

> Another doctrine of the Stoics is that there is nothing intermediate between virtue and vice; while the Peripatetics assert that there is a stage between virtue and vice, being an improvement on vice which has not yet arrived at virtue.

The Stoics believe there is no middle ground between virtue and vice, whereas the Peripatetics hold that there is an intermediate state of moral improvement.

_Highlights a key difference between Stoic and Peripatetic ethics._

> Moreover, Chrysippus is of opinion that virtue can be lost, but Cleanthes affirms that it cannot; the one saying that it can be lost by drunkenness or melancholy, the other maintaining that it cannot be lost on account of the firm perceptions which it implants in men.

Chrysippus thinks virtue can be lost through drunkenness or depression, while Cleanthes argues it is permanent due to the strong impressions it creates.

_Illustrates an internal Stoic debate on the permanence of virtue._

> Again, they affirm that it is of itself sufficient for happiness, as Zeno says, and he is followed in this assertion by Chrysippus in the first book of his treatise on Virtues, and by Hecaton in the second book of his treatise on Goods.

Zeno, Chrysippus, and Hecaton all assert that virtue alone is enough for happiness.

_Central Stoic doctrine of the self-sufficiency of virtue._
