Acting on Principles: A Thomistic Perspective in Making Moral Decisions

Acting on Principles, the product of over thirty years of teaching, gives a comprehensive overview of the Moral Theology of St. Thomas Aquinas, placing it in dialogue with contemporary ethical theory and developments in Catholic theology since the Second Vatican Council. Suitable for students of ethics and moral theology, and general readers seeking Christian guidance in the formation of conscience and moral decision making, it presents the classical Catholic ethical tradition in a clear and lively style.
