Aristotle's Pain

I really had a hard time reading and understanding this book. I eventually chose Book II chapter 3 on page 267.” But we must take someone’s pleasure or pain following on his actions to be sign of his state.”
Pleasure can be a very powerful motivator and very difficult to overlook but good things occur when we do things that are difficult for us and may cause pain. Aristotle believed that those who can handle the pain and pleasure experience will be good people.
