It’s an interesting question. Aristotle thought that a good person was a person who lived a worthwhile life.
in this sense we have what we might call the boundaries of moral action- which is largely what people would recognise from the 10 commandments- don’t murder, don’t steal, don’t lie, don’t cheat, don’t be jealous, don’t have affairs.
but this is just the limitations on action- no action that constitutes these can be something that contributes to a worthwhile life. Within this “field of play” we then need to make decisions about what we want to do to arrange our lives such that they are worthwhile. Which means we need to set goals that are good in themselves, and then pursue rational action to achieve those goals.
He then goes to consider what might be considered worthwhile in itself, is it money? Honour? Pleasure? Each of these he in turn examines and dismisses as limited in so far as they are fundamentally good for something else, rather than good for themselves.
Aristotle’s solution is that a contemplative life is the life that is worthwhile in itself- a life spent considering what is true, good, one and beautiful. My own view is that a life must be spent on self-sacrifice of some kind. We have one life, and have to spend it in some way, and so I hope that by choosing to be a parent and sacrificing myself for my spouse and children, to discover by this life my own limitations and selfishness (nothing will show your own selfishness like kids) and work to overcome them.
So- are you a good person? what are you pursuing in your life? Something that you consider good in itself, however perfectly or imperfectly you do this, or something that is a transitory good?
