Axiology is the branch of philosophy that examines values. It explores the nature of values in general rather than focusing specifically on moral values. Axiologists examine different types of values and take different perspectives on the reality of values. Axiology seeks to understand what makes one person's life better than another's and how to assess the value of a life. It also plays a role in determining the best consequences of actions and in discussions about the existence of God and the best possible world.
