Foundations of Ethics

In Foundations of Ethics, W. D. Ross presents a systematic defense of ethical intuitionism while engaging with the broader metaphysical questions that underpin moral philosophy. The work serves as both a refinement of his earlier ethical theory and an exploration of how moral knowledge relates to questions about ultimate reality and the divine order. Ross argues that moral truths are self-evident to properly functioning human reason, existing as objective features of reality that require explanation beyond naturalistic accounts.

The monograph critiques both subjectivist and purely naturalistic approaches to ethics, contending that they fail to account for the categorical nature of moral obligations. Ross maintains that the objectivity and universality of moral principles point toward a transcendent foundation, though he approaches this conclusion with characteristic philosophical caution. He examines how the existence of objective moral facts creates what might be termed a metaphysical puzzle: if moral properties are real but not reducible to natural properties, their ontological status requires careful analysis.

Ross engages particularly with the utilitarian tradition and with contemporary emotivists, arguing that both positions ultimately undermine the genuine authority of moral claims. His method combines careful conceptual analysis with appeals to moral experience, suggesting that competent moral agents directly apprehend rightness and wrongness through a form of intellectual perception analogous to mathematical intuition. This epistemological framework leads him to consider whether moral intuition might serve as a form of insight into the fundamental structure of reality.

The work's significance for discussions about God lies in its implicit argument that objective morality requires metaphysical grounding. While Ross does not develop an explicit moral argument for theism, his analysis suggests that the best explanation for the existence of objective moral facts involves reference to a transcendent source of value. He examines how moral obligations possess a unique kind of necessity that differs from both logical and natural necessity, implying a distinctive metaphysical category that naturalistic worldviews struggle to accommodate.

Ross's careful phenomenology of moral experience and his defense of non-natural moral properties provide important resources for those who see ethics as pointing beyond the material world. His work demonstrates how serious reflection on the nature of moral knowledge and moral reality leads inevitably to fundamental metaphysical questions about the ultimate structure of reality and the possible role of divine intelligence in grounding objective values.
