Eudemonism is a philosophy that defines right action as that which leads to "well being." The concept originates in Aristotle's Ethics. In Aristotle eudemonism means that all correct actions lead to the greater well being of the individual human. By extending well being from the narrowest concerns to the largest, all social rules can be adduced. Augustine of Hippo adopted the concept as beatitudo, and Thomas Aquinas worked it out into a Christian ethical scheme. For Aquinas, well-being is found ultimately in a direct perception of God, or complete blessedness.
