Value and Virtue in a Godless Universe

This monograph presents a systematic defense of robust realism about ethics within a naturalistic framework, directly challenging the widespread assumption that objective moral values require divine grounding. Wielenberg argues that certain moral facts exist as brute features of reality, neither requiring nor admitting of further explanation, thus undermining a central premise of moral arguments for God's existence.

The work engages primarily with theistic moral philosophers who contend that atheism leads inevitably to moral nihilism or relativism. Against figures like William Lane Craig and Robert Adams, who argue that objective moral values cannot exist without God, Wielenberg develops an account of "godless normative realism." His approach draws on G.E. Moore's conception of non-natural moral properties while incorporating contemporary work in metaethics to show how moral facts can supervene on natural facts without being reducible to them.

Wielenberg's methodology combines rigorous conceptual analysis with engagement across multiple philosophical traditions. He examines classical virtue ethics, particularly Aristotelian accounts of human flourishing, demonstrating how virtue-based approaches to ethics can function independently of theistic commitments. The work also incorporates insights from evolutionary psychology and moral psychology, though Wielenberg carefully distinguishes between explaining the origins of moral beliefs and grounding the truth of moral claims.

A distinctive contribution lies in Wielenberg's treatment of the relationship between meaning and morality in a godless universe. Rather than conceding that atheism entails nihilism about life's meaning, he argues that objective values provide sufficient grounds for meaningful human existence. This involves detailed engagement with existentialist philosophy, particularly Sartre and Camus, though Wielenberg ultimately rejects their subjectivist conclusions about value.

The monograph's significance extends beyond academic philosophy of religion into broader cultural debates about secularization and moral foundations. By providing a sophisticated philosophical framework for objective morality without God, Wielenberg offers intellectual resources for those who seek to maintain robust moral commitments while rejecting religious metaphysics. His work represents one of the most comprehensive attempts to date to show that the moral argument for God's existence fails because its crucial premise—that objective morality requires divine grounding—is false. The book thus serves as an important counterpoint to theistic moral philosophy while contributing constructively to secular moral theory.
