This Element has two aims. The first is to discuss arguments philosophers have made about the difference God's existence might make to questions of general interest in metaethics. The second is to argue that it is a mistake to think we can get very far in answering these questions by assuming a thin conception of God, and to suggest that exploring the implications of thick theisms for metaethics would be more fruitful.

In On Divine Revelation—one of Garrigou-Lagrange’s most significant works, here available in English for the very first time—he offers a classic treatment of this foundational topic. It is an organized and thorough defense of both the rationality and supernaturality of divine revelation. He presents a careful yet stimulating account of the scientific character of theology, the nature of revelation itself, mystery, dogma, the grace of faith, the powers of human reason, false interpretations thereof (rationalism, naturalism, agnosticism, and pantheism), the motives of credibility, and much more. Though written a century ago, On Divine Revelation will restore confidence in theology as a distinct and unified science and return focus to the fundamental questions of the doctrine of revelation. It also serves as a salutary corrective to contemporary theology’s anthropocentrism and concern with what is relative in revelation and religious experience by reorienting our theological attention to what is most certain, central, and sure in our knowledge of divine revelation: the Triune God who has revealed his inner life and salvific will. Readers will see the great splendor of the gift of divine revelation: radiant with credibility before the gaze of reason and drawing our supernatural assent to the mysteries through the gift of faith. As Fr. Cajetan Cuddy, O.P. observes, “On Divine Revelation . . . is a stunning work of inestimable value. No other subsequent work on this topic has come close to meeting it (much less surpassing it).”

Early modern Europe was the birthplace of the modern secular outlook. During the seventeenth century nature and human society came to be regarded in purely naturalistic, empirical ways, and religion was made an object of critical historical study. John Locke was a central figure in all these events. This study of his philosophical thought shows that these changes did not happen smoothly or without many conflicts of belief: Locke, in the role of Christian Virtuoso, endeavoured to resolve them. He was an experimental natural philosopher, a proponent of the so-called 'new philosophy', a variety of atomism that emerged in early modern Europe. But he was also a practising Christian, and he professed confidence that the two vocations were not only compatible, but mutually sustaining. He aspired, without compromising his empirical stance, to unite the two vocations in a single philosophical endeavour with the aim of producing a system of Christian philosophy.
