The Naturalistic Fallacy

Geach is best known for his contributions to theoretical philosophy: Most of his more than one hundred papers and a dozen books are on logic, philosophy of language and metaphysics. But he also made significant contributions to ethics. Particularly influential were a series of short metaethics papers, which are small masterpieces, both in terms of philosophical content and style. In usually less than ten pages, Geach delivers sharp analyses and powerful objections against influential schools. His arguments are always so clear (...) and his examples so simple that they leave the reader wondering why no one before Geach detected the problems he points out. (shrink)

I reconstruct a plot in the twentieth-century Anglo-Saxon ethical discussion. I discuss first the reasons why in the first half of the twentieth century the claim of a neutral character of metaethics vis-a-vis normative ethics was generally accepted; then I discuss the reasons for a U-turn that took place in 1958, which brought back to the forefront two traditional schools of normative ethics, Kantian and Utilitarian, and the reasons for criticism from the new school of virtue ethics. I conclude by (...) the claim that intuitionism and Kantian ethics will still be on the agenda for some time. (shrink)

The Evolutionary Manifesto shows that evolution is directional and demonstrates that this has major implications for humanity. The Manifesto shows that humanity must align its social systems and behaviour with the trajectory of evolution if we are to survive and thrive into the future. The Manifesto goes on to demonstrate that humanity has an essential role to play in the future evolution of life on this planet. It demonstrates that life on Earth has reached a critical stage in evolution’s trajectory. (...) Up to now evolution has moved along its trajectory blindly and unconsciously. But if evolution on Earth is to continue to advance successfully in the future, the process will have to be driven intentionally and consciously by humanity. In this way, a proper understanding of evolution shows us how we can live a life that matters in a larger scheme of things. An evolutionary worldview answers the fundamental existential question that faces us all: “What should I do with my life?” The Manifesto outlines in broad terms what humanity must do to advance the evolutionary process—how we will intentionally have to re-make our political, social and economic systems, and how we will need to develop our cognition and consciousness. As such, the Manifesto presents a detailed case for evolutionary activism--coordinated action directed at advancing the evolutionary process intentionally. (shrink)

Nietzsche’s late writings present a value opposition of health and decadence based in his conception of organic life. While this appears to be a moral ideal that risks the naturalistic fallacy of directly deriving norms from facts, it instead describes a meta-ethical ideal: the necessary conditions for any kind of moral agency. Nietzsche’s ideal of health not only evades but also dissolves the naturalistic fallacy by suggesting that the specific content of morality is irrelevant. If health is measured by power (...) over one’s drives rather than the environment, then the source of moral conflict—organic life’s essential tendency toward domination—is surmounted by successful integration of any moral norms, regardless of content. Nietzsche’s concept of health draws on his characterization of organic life as essentially ‘exploitation’: growth through domination of the environment (BGE 259, GM II: 12). In animals, power coincides with happiness, while health and decadence track the correspondence between instinct and happiness (TI II: 11). This simple picture is complicated by the Genealogy, where Nietzsche depicts human nature as an animal illness caused by civilization’s disruption of the natural correspondence of instinct and happiness. Civilization shapes this ‘sick animal’ into the distinctly human ‘sovereign individual’ (GM III: 13, II: 2), restoring the harmony of instinct and happiness in an internal hierarchy of drives. So, sovereign individuality is a distinctly human model of health. Although life is exploitation, human health does not coincide with greater environmental power, but rather an internal qualitative expansion of power: greater variety and tension among drives, greater ‘wholeness in diversity’ in the ‘social structure’ of the self (BGE 212, 12). Nonetheless, health is not a moral criterion, but instead the precondition of moral agency. The subordination of drives to a commanding hierarchy grounds the ability to uphold any moral principles at all, to make and keep promises to oneself and others. Moral agency coincides, in turn, with overcoming the source of moral conflict in organic life’s drive for growth. The unification of opposing drives provides pleasure in power over oneself rather than one’s environment, the ‘happiness of high tension’ among drives (BGE 260), and in environmental resistance, a need for ‘equal opponents’ (TI IX: 38, EH 1: 7). Consequently, Nietzsche’s meta-ethical ideal supports a moral pluralism that supports any moral content. Moral conflicts arise precisely to the degree individuals are incapable of achieving moral agency, but they dissolve as moral agency of any kind is more widely achieved. (shrink)

In this module I set out the Moral Non-Naturalism of Pūrva Mīmāṃsā as a version of Deontology that defines duty in terms of its beneficent properties. It elucidates the scheme of right living according to ordinance or command. Whereas natural accounts of moral terms suffer from circularity (by merely re-naming of a natural property with a moral term, which then serves to justify its moral appraisal), proponents of Mīmāṃsā defend their position by offering the Vedas as constituting independent evidence about (...) what yields goodness. In some ways, the argument provided by the defenders of Mīmāṃsā prefigure Moore's complaint of the Naturalistic Fallacy, but the Mīmāṃsā approach doesn't claim that defining natural properties by ethical terms is a fallacy: it is simply circular.

In the first part of this paper, I try to clear the ground from frequent misconceptions about the relationship between fact and value by examining some uses of the adjective “natural” in ethical controversies. Such uses bear evidence to our “natural” tendency to regard nature (considered in a descriptive sense, as the complex of physical and biological regularities) as the source of ethical norms. I then try to account for the origin of this tendency by offering three related explanations, the (...) most important of which regards it as the outcome of an adaptation: if any behaviour that favours our equilibrium with the environment is potentially adaptive, nothing can be more effective for this goal than developing an attitude toward the natural world that regards it as a dispenser of sacred norms that must be invariably respected. By referring to the Aristotelian notion of human flourishing illustrated in the first part of the paper, in the second I discuss some ethical problems raised by mini-chips implantable under in our bodies. I conclude by defending the potential beneficial effects of such new technological instruments. (shrink)

This collection of essays by acclaimed philosophers explores Bertrand Russell's influence on one of the dominant philosophical approaches of this century. Michael Dummett argues that analytical philosophy began with Gottlob Frege's analysis of numbers. Frege had begun by inquiring about the nature of number, but found it more fruitful to ask instead about the meanings of sentences containing number words. Russell was to exploit this method systematically. I reflect on the essays of Charles R. Pigden, David Lewis as an exponent (...) of a variant of Russell's position: the good is what we are ideally disposed to desire to desire, and Greenspan's suggestion that Russell adopted some element of the Marxist theory on morals.

In this paper we critically examine and seek to extend Philip Kitcher’s Ethical Project to weave together a distinctive naturalistic conception of how ethics came to occupy the place it does in our lives and how the existing ethical project should be revised and extended into the future. Although we endorse his insight that ethical progress is better conceived of as the improvement of an existing state than an incremental approach towards a fixed endpoint, we nonetheless go on to argue (...) that the metaethical apparatus Kitcher constructs around this creative metaethical proposal simply cannot do the work that he demands of it. The prospect of fundamental conflict between different functions of the ethical project requires Kitcher to appeal to a particular normative stance in order to judge specific changes in the ethical project to be genuinely progressive, and we argue that the virtues of continuity and coherence to which he appeals can only specify rather than justify the normative stance he favors. We conclude by suggesting an alternative approach for ethical naturalists that seems to us ultimately more promising than Kitcher’s own. (shrink)

In recent years there has been a growing interest among mainstream Anglophone moral philosophers in the empirical study of human morality, including its evolution and historical development. This chapter compares these developments with an earlier point of contact between moral philosophy and the moral sciences in the early decades of the Twentieth century, as manifested in some of the less frequently discussed arguments of G. E. Moore and W. D. Ross. It is argued that a critical appreciation of Moore and (...) Ross’s response to the emerging moral sciences of their day has significant implications for contemporary moral epistemology. The chapter also offers a novel interpretation of G. E. Moore’s ‘open question argument’. (shrink)

The history of philosophy can be seen either as a contribution to history or a contribution to philosophy or perhaps as a bit of both. Hutchinson fail on both counts. The book is bad: bad in itself (since it quite definitely ought not to be) and bad as a companion to Principia (since it sets students a bad example of slapdash, lazy and pretentious philosophizing and would tend to put them off reading Moore). As a conscientious reviewer I ploughed through (...) every page and I have to say that I resented every minute of my life that I wasted on the book. Don’t waste any of yours. (shrink)

Survey article on Naturalism dealing with Hume's NOFI (including Prior's objections), Moore's Naturalistic Fallacy and the Barren Tautology Argument. Naturalism, as I understand it, is a form of moral realism which rejects fundamental moral facts or properties. Thus it is opposed to both non-cognitivism, and and the error theory but also to non-naturalism. General conclusion: as of 1991: naturalism as a program has not been refuted though none of the extant versions look particularly promising.

I have two aims in this paper. In §§2-4 I contend that Moore has two arguments (not one) for the view that that ‘good’ denotes a non-natural property not to be identified with the naturalistic properties of science and common sense (or, for that matter, the more exotic properties posited by metaphysicians and theologians). The first argument, the Barren Tautology Argument (or the BTA), is derived, via Sidgwick, from a long tradition of anti-naturalist polemic. But the second argument, the Open (...) Question Argument proper (or the OQA), seems to have been Moore’s own invention and was probably devised to deal with naturalistic theories, such as Russell’s, which are immune to the Barren Tautology Argument. The OQA is valid and not (as Frankena (1939) has alleged) question-begging. Moreover, if its premises were true, it would have disposed of the desire-to-desire theory. But as I explain in §5, from 1970 onwards, two key premises of the OQA were successively called into question, the one because philosophers came to believe in synthetic identities between properties and the other because it led to the Paradox of Analysis. By 1989 a philosopher like Lewis could put forward precisely the kind of theory that Moore professed to have refuted with a clean intellectual conscience. However, in §§6-8 I shall argue that all is not lost for the OQA. I first press an objection to the desire-to-desire theory derived from Kripke’s famous epistemic argument. On reflection this argument looks uncannily like the OQA. But the premise on which it relies is weaker than the one that betrayed Moore by leading to the Paradox of Analysis. This suggests three conclusions: 1) that the desire-to-desire theory is false; 2) that the OQA can be revived, albeit in a modified form; and 3) that the revived OQA poses a serious threat to what might be called semantic naturalism.

The paper reconstructs Moore's Open Question Argument (OQA) and discusses its rise and fall. There are three basic objections to the OQA: Geach's point, that Moore presupposes that ?good? is a predicative adjective (whereas it is in fact attributive); Lewy's point, that it leads straight to the Paradox of Analysis; and Durrant's point that even if 'good' is not synonymous with any naturalistic predicate, goodness might be synthetically identical with a naturalistic property. As against Geach, I argue that 'good' has (...) both predicative and attributive uses and that in moral contexts it is difficult to give a naturalistic account of the attributive 'good'. To deal with Lewy, I reformulate the OQA. But the bulk of the paper is devoted to Durrant's objection. I argue that the post-Moorean programme of looking for synthetic identities between moral and naturalistic properties is either redundant or impossible. For it can be carried through only if 'good' expresses an empirical concept, in which case it is redundant since naturalism is true. But 'good' does not express an empirical concept (a point proved by the reformulated OQA). Hence synthetic naturalism is impossible. I discuss direct reference as a possible way out for the synthetic naturalist and conclude that it will not work. The OQA may be a bit battered but it works after a fashion. (shrink)

Synthesis of different models about the origin of morality with a discussion about possible normative consequences.

More than a century ago, G. E. Moore famously attempted to refute ethical naturalism by offering the so-called open question argument (OQA), also charging that all varieties of ethical naturalism commit the naturalistic fallacy. Although there is consensus that OQA and the naturalistic-fallacy charge both fail, OQA is sometimes vindicated, but only as an argument against naturalistic semantic analyses. The naturalistic-fallacy charge, by contrast, usually finds no takers at all. This paper provides new grounds for an OQA thus restricted. But (...) it aims chiefly at vindicating a version of the naturalistic fallacy, „the semantic-naturalist fallacy‟ (SNF), that we think defensible. We first argue that the openness of the question OQA raises against such analyses hinges on self-ascriptive, comparative judgments of content, which may be considered a priori warranted. We then provide independent reasons for the claim that the sort of mistake committed by naturalistic analyses in fact amounts to a pragmatic fallacy of a kind familiar in petitio principii and other forms of viciously circular inference. Of interest here are naturalistic analyses of ethical terms or concepts, not of properties. Our OQA (OQA*) raises an objection to the former. For no such semantic analyses can get off the ground unless moral terms are content-equivalent to purely descriptive terms, which amounts to saying that they must instantiate the same semantic types. Suppose „good‟ is the analysandum and „pleasure maximizing‟ the analysans (whichever purely descriptive term or terms would turn out to be the correct descriptive analysis of the target analysandum) of a certain semantic analysis. The claim that such terms are content-equivalent appears to be open to doubt on a priori grounds. After 1 all, whether one‟s own tokens of „good‟ and „pleasure maximizing‟ have/don‟t have the same content is a first-person, comparative judgment of content. Evaluating the proposed analysis requires, then, a self-ascriptive, comparative judgment of content.1 Judgments of this sort are thought to have a special epistemic status, since they seem grounded in neither evidence nor inference..
