Here's why:
* Arete is a Greek word that means "excellence" or "virtue."
* It's often associated with the concept of striving for moral perfection, which inherently involves compassion and empathy.
The other words don't fit:
* Ugly: Arete is a positive concept, not related to physical appearance.
* Hard: While pursuing excellence can be challenging, it's not the primary meaning of arete.
* Simple: Arete is a complex concept that involves moral and ethical development.
