Brink on Moral Realism and the Foundations of Ethics

David Brink's moral philosophy represents a sophisticated defense of moral realism against the prevailing skepticism of late twentieth-century metaethics. His work systematically challenges the view that moral properties lack objective reality, arguing instead that moral facts exist independently of human beliefs or attitudes. This position carries significant implications for theological discourse, as the objectivity of moral values has historically served as a key premise in moral arguments for God's existence.

Brink develops his moral realism through a naturalistic framework that grounds moral properties in natural facts about human welfare and social cooperation. He contends that moral truths emerge from facts about what promotes human flourishing, without requiring supernatural foundations. This naturalistic approach directly engages with divine command theories and other theological metaethical positions that locate moral authority in God's will or nature. By defending the objectivity of ethics without appeal to transcendent sources, Brink provides resources for those who seek to maintain moral realism while rejecting theistic foundations.

The work addresses several challenges to moral realism that parallel objections to religious belief. Brink examines the argument from disagreement, which claims that persistent moral disputes undermine objectivity, much as religious diversity challenges claims to theological truth. He also confronts the queerness objection, which holds that objective moral properties would be metaphysically strange entities. His responses to these challenges offer strategies that theologians might adapt when defending the reality of divine attributes or religious truths against similar skeptical arguments.

Brink's coherentist epistemology proves particularly relevant to discussions of religious knowledge. He argues that moral beliefs achieve justification through their place in reflective equilibrium with other beliefs, rather than through foundational certainty. This approach suggests ways of understanding religious belief that avoid both dogmatism and relativism. His treatment of moral motivation also bears on debates about divine command theory, as he argues that recognition of moral facts can motivate action without external sanctions.

The monograph's influence extends beyond pure metaethics to shape contemporary discussions of practical ethics and political philosophy. By defending objective moral truth while rejecting supernatural grounding, Brink's work exemplifies a secular approach to ethics that neither reduces to subjective preference nor requires theistic commitment. His arguments thus provide important challenges and resources for those engaged in natural theology and philosophical reflection on morality's relationship to divine reality.
