Living the Truth: A Theory of Action (review)

Klaus Demmer is one of the most influential Catholic moral theologians in Europe since Vatican II. Unfortunately, he is relatively unknown in America. Living the Truth is only the second of his works to be translated into English, although other translations are anticipated. In Living the Truth, Demmer provides an incredibly balanced and nuanced work of fundamental moral theology and brims with insights. Not content with easy answers or oversimplifications, Demmer seeks in this book not only to chart a way between apparent opposites but also to synthesize the best of both into a new unity.

For example, Demmer returns regularly to the question of the foundation and role of moral norms. Norms are indispensable in the life of the “ethical personality,” the person who is fully alive as a human being. They serve to open a person to the truth and to freedom and help to make a space for genuinely good, free, and vibrant action. However, norms are not at the heart of Demmer’s ethics, either as a discipline or in actual life. He also speaks of the ways in which a person establishes norms for herself even as he is careful to avoid relativism or subjectivism. Acknowledging that norms derived from a natural law ethics are true and important and that Christian morality may not be able to add any propositional content to natural law, he also argues at length that Christianity does in fact significantly shape a natural law ethics into something that is both deeper and more expansive. For Demmer, the Christian context changes the basis and meaning of morality. Although frustratingly spare with examples, he brings to the fore the difference between grounding human dignity in human nature as reason can grasp it and grounding it more specifically in the image and likeness of God and the love shown in the incarnation and redemption.

Demmer’s moral theology is profoundly human and existential; it is immersed in the context and texture of real human experience. In many ways, it is very pastoral. It certainly manifests a depth of psychological insight into the nature and workings of the human mind, for example, in analyzing the ways in which people fall into pride and self-deception (33–37).

Living the Truth’s concern with truth and truthfulness is an important and timely theme. Once again, Demmer synthesizes distinct elements. Truthfulness is a multifaceted reality, referring both to internal and external forces. Systematically grounding his ethics in a robust classical metaphysic, Demmer understands the “true,” the “good,” and “being” to be related as transcendentals (42). The “truth” opens one up to “goodness,” which in turn allows for the flourishing of the human person. Far from being restrictive, the truth opens up possibilities for true freedom. But this only occurs when it is internalized as “truthfulness,” a virtue of many dimensions that Demmer unfolds throughout the book, particularly in the last of the three main parts.

Living the Truth is very dense. It definitely is not an undergraduate text. Both the meaning of individual sentences and the flow of Demmer’s thought are elusive at times. Many subsections discuss a range of ideas and seem at times to wander. Even readers with a strong background in moral theology will find it necessary to reread and think carefully in order to catch the precise meaning of specific phrases and follow the argument. Nonetheless, the rewards are well worth the effort. Every moral theologian owes it to herself to read this book.
