Answer:
Aristotle believed the eight virtues were developed through learning and habitual practice.
Step-by-step explanation:
“For the things we have to learn before we can do them, we learn by doing them...Men become builders by building and lyre players by playing the lyre; so too we become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts.”
“These virtues are formed in man by his doing the actions ... The good of man is a working of the soul in the way of excellence in a complete life.”
“Virtue lies in our power, and similarly so does vice; because where it is in our power to act, it is also in our power not to act...”
(Some quotes from The Nicomachean Ethics by Aristotle)
