Julia Annas has advocated ethics based on character, building on ideas attributed to Greek philosopher, Aristotle and making them relevant for contemporary moral discourse.[6] She has argued that being virtuous involves "practical reasoning"[7] which can be compared to the "exercising of a practical skill". Hence, she argues, rather than relating virtues to rules, principles, or an end goal, Annas says, first, people should ask how they can improve their moral "skills".[7]
