Aristotle tells us that there are good people in the world. These are those who exhibit excellences – excellences of thought and excellences of character. His phrase for excellences of character – "êthikai aretai" – we usually translate as moral virtue or moral excellence. When we speak of a moral virtue or an excellence of character, the emphasis is on the combination of qualities that make an individual the sort of ethically admirable person that he is. Aristotle defines virtuous character at the beginning of Book II in "Nicomachean Ethics": "Excellence of character, then, is a state concerned with choice, lying in a mean relative to us, this being determined by reason and in the way in which the man of practical wisdom would determine it. Now it is a mean between two vices, that which depends on and that which depends on ”. In Aristotle's view, good character is based on two naturally occurring psychological responses that most people experience without difficulty: our tendency to take pleasure from self-realizing activity and our tendency to form friendly feelings toward others under specific circumstances. Based on his view, virtually everyone is capable of becoming better and they are the ones responsible for actions that express (or could express) their character.
