Answer:
This question is incomplete, but I will help you understand it.
Explanation:
With the example given, we are facing a self-interested thinking.
Aristotle tells us that the good man is interested in doing good to others and the more honest he is, the more good he does; and that when it comes to a friend he can forget himself.
But since his friend is his, he also has to love himself in the same way.
Egoism is a term that is used for those who only think of themselves to satisfy their worldly desires and it is with this word that the common people judge them.
In this example, we can see how Jonathan affirms that his essay is better, having a self-interested thinking without caring about the evidence that Betty exposes.
