A Foundation for Ethics

James Franklin was a professor of mathematics at UNSW when he began teaching ethics to maths students in the first course of its kind in the world. He differed from many academics offering professional ethics courses in being a philosopher (and a historian, but jokes about him being a polymath must have worn very thin by now). Franklin has been defending realist metaphysics for many years, mainly in the philosophy of science and the philosophy of mathematics. In this latest book, he sets out a strong realist case for the foundation of ethics.

His very first sentence, “Ethics is not fundamentally about what to do,” is startling. Surely everybody knows, or else should know, that ethics is about what we should do and what we should not. As Franklin points out, however, rules, norms and injunctions do not hang in the air. They have a basis and he argues that that basis is the worth of persons. He points to cases where this is evident, such as when we become aware of human horror stories, like the murders of Srebrenica. We recoil at “the violation and destruction of something of immense value, a human life”. Instances of this recognition are not difficult to find, and they point us towards the fundamental worth of persons. That worth is Franklin’s foundation for ethics and the theme of this book.

The book is divided into sections dealing with objections to metaphysical or foundationalist theories of ethics, and those justifying a metaphysics of ethics in the intrinsic worth of persons. It should not need to be said that metaphysics is not about mysticism or alternatives to science but is the philosophy of fundamentals—in this case, the nature of the human person and what is proper to that nature. Franklin notes wryly that “a phobia of metaphysics is widespread in ethical theory”: foundations are out and constructions and moral scepticism are in. How anything can be constructed without foundations is a mystery Franklin explores in his early chapters. He takes the worth of human beings as basic. Such worth does not depend upon our value to others but on our humanity.

Interestingly, Franklin differs with traditional defenders of ethical realism, such as Aristotle and Aquinas, who hitch human worth to action. He argues, in contrast, that the worth of persons may be grasped with no practical purpose in mind, and, indeed this understanding must be so if we are to avoid viewing the worth of persons through their pursuit of goods such as knowledge, liberty or friendship. I’m not sure that the undoubtedly practical bias of Aquinas precludes such an appreciation, but the significant point is that Franklin’s emphasis on understanding human worth orients ethics differently. His focus is on the worth of persons rather than the worth of goods. This establishes a basis for ethics in moral realism rather than in the currently fashionable terms of an evolutionary survival or a convenient social fiction.

Franklin argues that traditional understandings of ethics (deontological, consequentialist and virtue theories) are at some, often unacknowledged, level committed to the worth of persons. Other candidates for grounding ethics, such as the Darwinian, the Calvinist, the Humean (after the Scottish philosopher David Hume), and those of Socrates and Aristotle are not so committed. Franklin’s disagreement with them all is that they focus on acts and rational action. They do not provide accounts of ethics relating to the significance of human worth. Divine command theorists, for example, place ethics wholly in the arbitrary decisions of God.

Evolutionary ethics travels a different path to a similarly arbitrary conclusion, explaining away rather than explaining what we know. The fittingness of moral norms to human evolution is pre-ordained by the theory, but what of the value to survival and reproduction of successful but repugnant practices like violence and theft? Then there is the evolutionary reduction of ethics to physiological explanations. The US entomologist Edward O. Wilson produced a well-known instance of this. He held that because natural selection produced the hypothalamus and limbic systems from which emotions like love, hate, fear and guilt arise, ethics, “if not epistemology and epistemologists”, can be explained in evolutionary terms. Presumably entomological knowledge claims could be explained in this way too.

Franklin shows such arguments to be invalid. He gives a parallel case: “We cannot know mathematical truths except through the calculations of our frontal cortex, therefore, we cannot know mathematical truths at all.” This, says Franklin, is an example of the “worst argument in the world”, a soubriquet bestowed upon this form of illogicality by David Stove.

Franklin takes Kant to be the philosopher who most fully gives human worth (dignity) its due. For Kant, human persons are ends in themselves, worthy of boundless respect, and able to accommodate a rich conception of human nature in individual worth. Not all deontological theories fare as well as Kant’s. Franklin argues that the pre-eminent political philosopher of the second half of the twentieth century, John Rawls, fails in trying to establish a non-metaphysical theory of justice. This is not a new criticism, but Rawls’s prominence and persuasiveness justify Franklin’s riposte. Rawls posits primary goods that any rational agent would seek to maximise were they in a position to choose a fair or just society. Franklin takes one of those goods, “a sense of one’s own worth”, and asks upon what that sense is founded. Assuming it is a sound claim, it must be based in some belief about oneself—which in Rawls’s terms may be generalised to a belief about persons—and which therefore “threatens to be ‘metaphysical’”. Another good, freedom, unavoidably raises a metaphysical problem. If freedom is not a delusion, and Rawls does not treat it as such, then that belief must be justified by something metaphysical about persons.

Other philosophers, such as the anti-foundationalist Richard Rorty, are no more successful than Rawls. They reject the metaphysics of ethics and thereby exclude questions about intrinsic human worth. Franklin’s confrontation of anti-metaphysical ethics is reminiscent of the post-war critiques of Iris Murdoch, Philippa Foot, Elizabeth Anscombe and Mary Midgley, the “metaphysical animals” who are the subject of a recent book by Clare MacCumhaill and Rachael Wiseman. This quartet refused to accept the enfeebled Oxford moral philosophy that fashionably rejected metaphysics in favour of the analysis of language, and gave no purchase on the recent evil of mass human destruction. Franklin’s critique of practical philosophers who believe that ethics is simply “traffic rules” for society echoes their challenge. As he puts it, persons are “not members of the human species”, but individuals, meaning that their worth comes not from belonging to a class but inheres in their personhood. Tragedy is a pointer to that status. The loss of a person in a war or an accident is a tragedy as the death of a kangaroo or the explosion of a star is not.

It is one of the strengths of Franklin’s book that he takes tragedy seriously. His criticisms of other theories draw heavily upon their failure to do so or do so sufficiently. That is because they have more regard for acting well or badly than for the worth of the person. Peter Singer is a good example. His valuing of experiences leads to counter-intuitive conclusions, such as an infant having no inherent right to life. Because an infant has no conscious interests to be counted, its worth depends on its value to others whose interests do count. If it is disabled, they might not wish to keep it alive and perhaps to replace it with another child at a more convenient time. That makes killing a child permissible or right. Such anaemic theory has no room for tragedy.

Franklin’s case is that we recognise that moral worth is grounded in our complex humanity, which points to a relation of supervenience. Supervenience means that one set of properties is grounded in another set without which it would not exist, as in the supervenience of chess strategy on the rules of chess or the supervenience of rational thought on logic. Understanding supervenience is grasping that the grounding properties give rise necessarily to very different supervenient properties. Franklin argues that supervenience is the bridge to worth. He is not dealing with the conceptual relations discussed by Hume, who suggested a sleight of hand in moving from descriptions to prescriptions, and much less with the “constructions” and other letters of transit that dominate much contemporary thinking about ethics. Returning to his very first proposition, Franklin points out that Hume’s is/ought objection applies to gaps between descriptions and prescriptions—actions—and not obviously to a gap between non-moral facts and worth.

Nevertheless, the Australian philosopher John Mackie challenged ethical facts as “queer”. He thought they were utterly unlike anything else in a universe of solid entities, like planets and tables. The problem with Mackie’s queerness objection is that it is not peculiar to morality. Knowing about other things shares the alleged problems of knowledge about ethical facts. Retaining facts about, say, logic as trouble-free while rejecting moral facts as fantastic is arbitrary, as Franklin, and others like John Finnis, another Australian, have argued. Mackie’s queerness objection would apply not only to morality but intentions, aesthetics, meaning and the truth of theories about the universe.

Against the reductionism attempted by E.O. Wilson or, say, those who believe thoughts are mere brain states, Franklin argues that supervenience adds to what there is. The supervenient relationship is not one of identity, but describes the rise of properties which exist because of their grounding in others. The supervenient entities would not exist without that grounding. This is the metaphysical core of Franklin’s work. It supports his argument that theories that attempt to avoid metaphysics cannot really do so.

The supervenience theory accounts for consistency in morality because it excludes irrelevant (non-grounding) properties, such as skin colour or sex. It also excludes human worth by degrees characteristic of instrumental goods. Knives are better or worse depending on their sharpness, the worth of cars is measured against performance standards, and so on. Human beings are not like this, worth less because they are poor or uneducated or worth more because of artistic talent or intelligence. Franklin’s argument is against depersonalisation as much as it is for a foundation for ethics.

He considers a range of qualities believed to endow humans with worth: rationality, freedom, detachment, giving and understanding reasons, and the exercise of aesthetic appreciation. Another is good will, which Kant identifies as the only unqualified good. In addition to these are rational capacities conferred by the emotions, among which love is the most significant. Simplifying Franklin’s argument, these characteristics, as elements in a unified self, separate persons from plant and animal life and from mechanical simulacra. It is upon persons, thus considered, that worth supervenes. Hence, when persons are deprived of some of these properties a sense of grief or shock or tragedy is a normal response.

Yet lists of characteristics united in a continuing, self-aware person cannot be the full story. Worth inheres in babies who have not actualised their capacities. Talk of lists of capacities and potentials in babies suggests they have value from being loved rather than being loved because they are valuable. Human persons defined in terms of characteristics could still be interchangeable without loss. Even adding the capacity to love does not fully individuate persons. Love does alter when it alteration finds. What intellectual and emotional capacities reveal is the unique capacity of human persons to realise themselves. The worth of individuality is most clearly evident in the realisation of potentials over a lifetime. It is essentially human to form and execute a plan of life. Franklin discusses individuality with insight, using examples from literature and life to show how the actualisation of potentials produces irreplaceable individuals. But the possession of potentials also supervenes on worth, as those who have lost children know.

These considerations of worth are enlarged in a chapter on the epistemology of worth: how is ethical knowledge possible? Here Franklin discusses emotions, such as empathy and love, as forms of ethical knowledge. Empathy, for example, is a sharing in another’s emotional life. We know how they feel. In knowing this, we know one of the bases of their worth. Someone shown photographs of Holocaust death camps, but who experiences no horror, “lacks a necessary insight into the worth of persons”. Such were the Nazis whose depravity allowed them to destroy something of worth, not only in others but in themselves.

By now the significance of establishing the worth of persons as the basis for ethics should be clear. Note that Franklin is properly modest about moving from intrinsic worth to moral precepts. He rejects such moves as implausible. Nor does he try to dissolve ethical dilemmas. He does not dodge difficult questions, including abortion, euthanasia, incarceration, war and equality, yet Franklin’s account of our obligations to others is not mysterious. As he says, “If persons were worthless, what they did or what was done to them would be of no moral significance.”

The ethical positions incompatible with Franklin’s moral realism include most obviously subjectivism, a strictly materialist atheism which regards human beings as not much more than star dust, and divine voluntarism, by which God’s commands make right and wrong.

I had the pleasure of reading this book in manuscript and have been thinking about it ever since, particularly its resonances with the theories of G.E. Moore and John Finnis. As a good philosophy book should, it raises difficult questions and gives strong arguments that its author occasionally and modestly admits are defeasible. While making demands of its readers—skipping chapters is not recommended—it is accessible to an educated audience without a background in philosophy. Both those seeking a convincing foundation for ethics, and those who believe none can be found, will find enlightenment in its pages. I can’t think of a better recommendation.
