Prolegomena to Ethics

Prolegomena to Ethics is a 1939 collection of essays by Scottish philosopher W. D. Ross that consolidates and expands his revisionist deontological theory, situating it within early 20th-century moral philosophy debates. The work addresses duty, prima facie obligations, and moral intuition, responding to influence from Immanuel Kant, Jeremy Bentham, John Stuart Mill, and critics such as G. E. Moore, while engaging contemporary figures including Bertrand Russell, A. J. Ayer, and R. M. Hare.

Background and Publication

Ross published the work after a career at Balliol College, Oxford and amid intellectual currents shaped by the Second World War, the aftermath of the First World War, and debates at Oxford University about analytic philosophy and moral realism. The volume synthesizes lectures and essays Ross presented at institutions like University of Edinburgh and references exchange with philosophers from Trinity College, Cambridge and Harvard University visiting scholars such as Alfred North Whitehead, G. E. Moore, and Henry Sidgwick. Oxford University Press issued the book in 1939, placing it alongside contemporaneous publications by Ludwig Wittgenstein, Bertrand Russell, and Frank Ramsey in shaping Anglo-American ethical discourse.

Central Arguments and Themes

Ross defends a pluralistic intuitionist account claiming that moral knowledge rests on immediate apprehensions of prima facie duties rather than on consequentialist calculations associated with John Stuart Mill or on categorical imperatives as formulated by Immanuel Kant. He introduces a hierarchy of duties—fidelity, reparation, gratitude, justice, beneficence, self-improvement, and nonmaleficence—arguing these are self-evident and grounded in moral experience in the tradition of Henry Sidgwick and opposed to the naturalistic fallacy criticized by G. E. Moore. Ross illustrates moral conflict situations using thought experiments akin to discussions by Peter Strawson and H. A. Prichard, insisting that moral deliberation identifies actual duties by weighing prima facie obligations rather than reducing them to a single principle as in theories advanced by Jeremy Bentham or utilitarian critics such as Richard M. Hare. He addresses epistemic status drawing on intuitionist resources associated with Moore, contrasts with emotivist claims from A. J. Ayer and C. L. Stevenson, and defends moral objectivity in lines comparable to arguments by Philippa Foot and Elizabeth Anscombe.

Relation to Kantian and Contemporary Ethics

Ross positions his view in explicit dialogue with Immanuel Kant: he accepts the deontological emphasis on duty but disputes Kant’s single categorical imperative and metaphysical grounding found in works like Groundwork of the Metaphysics of Morals. Ross instead proposes multiple self-evident duties similar to the pluralism debated by G. E. Moore and counterposed to the universalist formulations in Kantian ethics cited by Hermann Cohen and Friedrich Schiller. He engages contemporary ethicists including R. M. Hare on prescriptivism and Alasdair MacIntyre on virtue ethics, and addresses consequentialist critiques from John Rawls and utilitarian defenders such as Henry Sidgwick and Sidney Hook. Ross’s methodology also intersects with epistemological concerns in analytic circles influenced by Bertrand Russell and Ludwig Wittgenstein, while his emphasis on prima facie obligations anticipates later revival of pluralist accounts by scholars like Thomas Nagel and Bernard Williams.

Critical Reception and Influence

Initial reception combined admiration for Ross’s clarity with skepticism about the metaphysical status of prima facie duties; reviewers from The Times of London and academic commentators at King’s College, Cambridge offered mixed appraisals. Critics such as R. M. Hare and A. J. Ayer challenged his appeal to intuition as epistemically secure, while defenders including Philippa Foot and Elizabeth Anscombe saw value in restoring non-consequentialist resources. The book influenced mid-20th-century curricula at Oxford University and informed debates in the American Philosophical Association and at conferences like those organized by the British Society for Ethical Theory. Later philosophers—John Rawls, Derek Parfit, Thomas Nagel, and Bernard Williams—engaged Ross’s themes either by refinement or rebuttal, and contemporary moral pluralists trace intellectual lineage to Ross’s pluralist intuitionism alongside traditions represented by G. E. Moore and Henry Sidgwick.

Key Concepts and Terminology

Prima facie duty: Ross’s central term denoting conditional obligations akin to the notions discussed by H. A. Prichard and G. E. Moore; these are distinct from all-things-considered duties in Ross’s schema. Intuitionism: Ross situates his epistemology in the intuitionist lineage associated with G. E. Moore, Henry Sidgwick, and critics of emotivism like C. L. Stevenson. Pluralism: Ross’s rejection of monistic systems resembles positions later defended by Bernard Williams and contrasted with monists such as Immanuel Kant and Jeremy Bentham. Moral particularism critics like Jonathan Dancy respond to Rossian generality with differing emphases, while utilitarian and prescriptivist opponents including John Stuart Mill and R. M. Hare press for alternative decision procedures. The distinction between prima facie and actual duty grounds much contemporary discussion in journals and seminars at institutions such as Princeton University and Harvard University.
