Prepared and co-published by the National Catholic Bioethics Center in Philadelphia, this book is a combination of two lengthy essays written by Cardinal Ratzinger and delivered in talks when he was head of the Congregation for the Doctrine of the Faith. Both talks deal with the importance of conscience and its exercise in particular circumstances.


Ratzinger's reflections show that contemporary debates over the nature of conscience have deep historical and philosophical roots. He says that a person is bound to act in accord with his conscience, but he makes it clear that there must be reliable, proven sources for the judgment of conscience in moral issues, other than the subjective reflections of each individual.


The always unique and profound insights that the new Pope Benedict XVI brings to perennial problems reminds the reader of his strong warning before the recent Papal conclave of the great dangers today of the "dictatorship of relativism."
