What is revenge but courage to call in our honor's debts, and wisdom to convert others' self-love into our own

Question

what does that quote mean, its for edward young

Answer 1

When offended, your honor has been impugned. Hence the courage to call in honor's debts is to seek satisfaction (revenge) for the offense. In doing so, you appeal to a person's self-love to make it an affair of honor that must be defended, hence you are able to extract your revenge.

Think of the story The Count of Monte Cristo by Dumas.
