So, basically, virtue ethics has a main point in the fact that it tries to build people intellectually, where other systems mainly focus on imposing rules.
Naturally, if you teach a person to be smart and kind, you wont need any rules to begin with.
And if you dont teach a person to be smart and kind, imposing rules wont help much.
So the goal of virtue ethics is to work to develop certain virtues, such as intelligence, kindness, non-aggression...
It is mostly a process, and not a set of immediate rules.
For example, instead of telling kids to be generous, you tell them a sad story of a person who struggled greatly due to poverty, and they will be generous without you even telling them to be.
Its kinda like telling people to be smart. You cant tell people to be smart. But you can create a process to make them smarter.
So, you cannot tell people to be good. But you can make a process to make them good.
So a basic premise of virtue ethics is that being good and smart requires a process and not a simple imposing of rules.
You cannot tell a child "be smart" and expect it to be smart, for example. Same works with being good, kind, generous...ect.
It takes the building of premises in person, which are often more based on emotions than logic.
It takes a journey.
