This conclusion criticizes Daniel Dennett for dividing reality into first-class illata and second-class abstracta, and argues that fundamental physics directly studies extra-representational real patterns, while special sciences study real patterns located by means of the notional-world concepts of cohesion and causation. Dennett's abstracta are approximate descriptions of the illata, where the approximations in question usefully serve human purposes. By contrast, special-science real patterns are not approximations of (fundamental) physical real patterns. The primacy of physics constraint (PPC) is the only physicalist principle motivated by actual science, and it is too weak to support any form of reduction of special-science real patterns to physical real patterns. The special sciences often successfully track real patterns, an assertion based on the no-miracles argument rather than on any claim about how the special sciences inherit ontological seriousness from their relationship to physics.

This chapter argues that the idea of causation has similar status to ideas of cohesion, forces, and things. Appreciating the role of causation in a notional world is crucial to understanding the nature of the special sciences, and the general ways in which they differ from fundamental physics. Causation, unlike cohesion, is both a notional-world concept and a folk concept. Moreover, causation, unlike cohesion, is a basic category of traditional metaphysics, including metaphysics that purports to be naturalistic but falls short of this ambition. This chapter also argues that causation, just like cohesion, is a representational real pattern that is necessary for an adequately comprehensive science. It begins with an account that eliminates causation altogether on naturalistic grounds, and then shows, using principle of naturalistic closure (PNC)-mandated motivations, why this outright eliminativism is too strong. The eliminativist argument to be discussed is due to Bertrand Russell, whose view has some important contemporary adherents among philosophers of physics.

The paper replies to Wade Hands’s recent criticism of one part of my 2005 book, Economic Theory and Cognitive Science: Microexplanation (ETCS). Hands argues that my association of my view of the foundations of microeconomics with aspects of the thought of Lionel Robbins and Paul Samuelson is gratuitous and historically misleading. I argue in turn that Hands’s general criticism rests on his ignoring the fact that my treatment of both Robbins and Samuelson is explicitly critical. On Robbins, I argue that Hands’s concerns amount to an objection to me only given an absurd principle to the effect that the only non-misleading kind of associative relationship one can draw between two historical theses is identity. On Samuelson the dialectic is more complicated because, as a result of not understanding what philosophers call ‘externalism about intentional content’, Hands misreads the relationship I aim to construct between my general view and Samuelson’s.

McClamrock argues for a thesis he calls radical externalism' in the behavioral and cognitive sciences. In my paper, I contend that McClamrock's thesis, though true, is not radical. This is because he urges externalism with respect to cognitive task-individuation and task-explanation, both of which are standard practice in the relevant disciplines. Semantic externalism may remain contentious, I argue; but the sense in which philosophers continue to argue about it has little bearing on the actual conduct of cognitive science. I conclude with a diagnosis as to why externalism seems more contentious than it ought to

This paper is part of a larger project defending of the foundations of microeconomics against recent criticisms by philosophers. Here, we undermine one source of these criticisms, arising from philosophers' disappointment with the performance of microeconomic tools, in particular game theory, when these are applied to normative decision theory. Hollis and Sugden have recently articulated such disappointment in a sophisticated way, and have argued on the basis of it that the economic conception of rationality is inadequate. We argue, however, that their claim rests upon a misunderstanding of the concept of a game as it is used in microeconomics.

There are many general economic policies I favour such that I would feel significantly ashamed were I to succumb to bribery, or to institutional pressure short of physical threat, to publicly support their opposites. Here are a few of these policies: (1) Rich countries should not impose trade barriers, including subsidies for their own producers, against imports from poor countries. (2) Leaders of poor countries should be regarded as irresponsible when they imply to their people that their economic difficulties arise principally from wickedness and exploitative behavior on the part of rich countries – the moral urgency of (1) notwithstanding. (3) Much freer movement of people across national borders for purposes of labour should be allowed everywhere. (4) Destitution is an unduly severe penalty for laziness, lack of talent or intelligence, or bad luck. More productive people should provide the lazy, the unskilled and the unlucky with as large a basic income grant as is compatible with maximizing net social productivity (which no present society comes very close to doing, partly due to confused social morality and partly due to incentive-distorting tax systems).

Most philosophical accounts of the foundations of economics have assumed that economics is intended to be an empirical science concerned with human behaviour, though they have, of course, differed over the extent to which it has been or can be successful as such an enterprise. A prominent source of dissent against this consensus is Alexander Rosenberg. In his recent book, Rosenberg summarizes and completes his statement of a position that he has been developing for some time. He argues that although economists evaluate one another's work according to shared and rigorous standards of adequacy, these standards are strictly internal, like those of mathematics, instead of being derived from discoveries about contingent relationships between theoretical statements and empirical facts. Economics, that is to say, is essentially conceptual rather than empirical inquiry. In the following discussion, I will provide grounds for resisting Rosenberg's conclusion. The point of this criticism, however, is not mainly negative. Most of the historical preoccupations of the philosophy of economics, like those of the philosophy of science in general, have been epistemological. Careful attention to Rosenberg's argument, however, redirects our attention to ontological questions about the objects of economics, and this redirection, I will maintain, is to be welcomed. I will argue that while the majority of philosophers of economics is correct, as against Rosenberg, in regarding economics as an empirical science, the conventional view as to the identity of its empirical objects should be substantially revised under the pressure of Rosenberg's criticisms. My critical analysis of the implications of Rosenberg's work for the ontological commitments of economics is intended to furnish one line of argument towards my own conception of the objects of economics. This conception, which is still preliminary in many respects, will be briefly sketched toward the end of the present paper; a detailed account of it is given in Ross and LaCasse.

Murphy (2006) criticizes psychiatric nosology from the perspective of the philosophy of science, arguing that the model of pathology as encapsulated in the Diagnostic and Statistical Manual of Mental Disorders reflects a folk conception of the mental, and of malfunctioning, that is inadequately integrated with cognitive and behavioral neuroscience. The present paper supports this view through a case study of research on pathological gambling. It argues that recent modeling based on fMRI studies and behavioral genetics suggests a stipulative, non-seamless reduction of pathological gambling to a specific disorder of the mesolimbic dopamine system. This argument is agnostic as between prior philosophical commitments to realism or empiricism.

The aim of this report is to consider feasible conditions under which South Africa!!" processed (e.g., canned and other packaged) fruit industry would be internationally competitive and a profitable site of investment, and therefore able to resume a pattern of growth from which it departed in the early part of the present decade. This is in service of the wider aim of identifying, in a subsequent phase of the project, appropriate industrial policy measures which Government might put in place to assist the industry, in accordance with sound principles of national welfare optimization and public finance.

Of crucial importance to all parts of the transport services and materials sector in South Africa is the way in which the Government chooses to implement its ambitious plans to reinvest in the country’s basic infrastructure. How will it navigate competing demands from urban and rural environments, given the divergent economics that describe them? How will it balance the goals of poverty fighting, skills empowerment, and keeping SA internationally competitive, as it considers infrastructure project options?

This paper argues that the most common reading of Robbins’s Essay on the Nature and Significance of Economic Science in the methodology literature, according to which it was an historical foil for subsequent positivist-empiricist ideas, underestimates its contemporary relevance. In light of recent scholarship on 1930s positivism in philosophy, Robbins’s Essay is better interpreted as representing an attitude I call ‘broad positivism’, which remains a live option in contemporary philosophy of science. In consequence, the basis of Robbins’s preference for clear demarcation between economics and psychology should be regarded as not merely historical in interest, but as raising valid considerations against the widespread current trend towards ‘correcting’ aspects of economic theory by reference to psychological experiments.

Writing in the Business Day on 2 October 2007, economics journalist Hilary Joffe notes that “it was not long ago that there was a famine of infrastructure investment [in South Africa]; now there’s a feast, with each new week bringing reports of new projects and new, much higher estimates of the totals to be spent in years to come.” Joffe expresses enthusiasm about this, for reasons with which we agree: The infrastructure feast has already helped to raise SA’s investment ratio to nearly 21% of gross domestic product, from a low of below 15% just five years ago. We are already seeing the beginnings of a shift from consumptiondriven to investment-driven growth that the economy needs if it is to grow on a sustainable basis. And of course much of that infrastructure is already urgently needed; and the need will grow as economic growth takes place. However, she is immediately led to ask two pressing questions. First, “even if these are all good and necessary projects, can SA’s economy afford them … all at the same time?” And second, “is anyone counting the total cost to the economy and puzzling out which projects should take priority, and whether some should wait (or be dropped altogether)?”.

Critics of mainstream economics typically rest important weight on the differences between people and the 'agents' that populate economic theory and economic models. Hollis and Nell (1975) is both representative of and ancestral to many more recent variations on the theme. Lately, the upgraded status of behavioral economics (BE) within the discipline's mainstream has encouraged a number of writers to use revolutionary rhetoric in promotion of a 'paradigm shift' that includes the rejection of 'rational economic man' (Ormerod 1994, Heilbroner and Milburg 1995, Fullbrook 2003). The current leading developers of BE are generally more circumspect, claiming that their approach complements standard theory rather than promising to supplant it (Camerer and Loewenstein 2004, Angner and Loewenstein this volume). However, they generally join the more florid critics in supposing that microeconomics is bound to improve its empirical relevance to the extent that it substitutes the study of people for that of abstract economic agents. Another body of thought that promotes this view stems from Sen's (1977) attack on standard economic agents as 'rational fools', amplified in Davis's (2003) argument that since economic agents lack some essential properties of human individuals, economic theory requires fundamental reform if it is to make progress in explaining human behavior.

This paper critically discusses Amartya Sen’s case for broadening the basket of wellbeing indicators in development policy beyond income and consumption expenditure. I first argue that, contrary to what Sen has suggested, the theoretical and practical motivations that he gives for this do not form a mutually complementary set. In the second, policy-focused, part of the paper I present problems Sen’s approach to measurement raises in the context of a case study from rural South Africa. I conclude by suggesting that development indicators should be regarded as narrower – in particular, that we should give privileged attention to women’s incomes – rather than broader.

Three recent book-length studies in the philosophy of economics (Mirowski 2002, Davis 2003, Ross 2005) have drawn attention to the fact that mainstream economic theory has consistently avoided commitment to any particular model of the person. This is the most significant respect in which economics has kept aloof from part of psychology. The widespread belief, on the other hand, that economists’ attentiveness to the psychology of choice and decision had to wait for the Allais challenge and then for Kahneman and Tversky is a myth. It is true that for a brief period after World War II economists led by Samuelson tried to operationalize choice as analytically derivative from observed consumer demand. This was a minor episode in the history of theory. Ross (2005) argues that, if anything, mainstream microeconomics has been more sensitive to theoretical fashions in the psychology of choice than has been good for it.

‘Naturalism’ about the ontology of society can most blandly be characterized as the belief that social phenomena are among the class of natural phenomena. Contemporary scholars are apt to regard this thesis as bland because its denial seems quaint at best, if not outright unhinged, after a century and a half of development in the social sciences. There has, however, been a powerful tradition in (at least) Western culture that has understood the ‘artificial’ as a primary contrast class with the ‘natural’, and which has interpreted the social as a creation of human beings that stands over and against the natural realm. Often..

I discuss the role of economics in the study of social cognition. A currently popular view is that microeconomics should collapse into psychology partly because cognitive science has shown that valuation is constitutively social, whereas non-psychological economics insists that it is not. In the paper I resist this view, partly by reference to the relevant history of economic theory, and partly by reference to an alternative model of the way in which that theory complements, without reducing to, psychological accounts of social cognition.

Economics is the only established discipline that is regularly charged not just with including ideologically motivated research programs and hypotheses, but with actually being (at least in its institutionalized mainstream form) an ideology. As Coleman (2002) documents, this charge has followed economics since its modern inception as ‘political economy’ in the eighteenth century. There is a veritable tradition of what Coleman calls ‘anti-economics’, most famously populated by people such as Ruskin and Carlyle, and extending in the contemporary environment to include philosophers John Gray[1] and John Dupré,[2] numerous popular agitators associated with environmentalism and the self-styled ‘anti-capitalist’ and ‘anti-globalization’ movements, and no small number of disillusioned economists.[3] Of course all disciplinary establishments rightly attract critical literature; but as far as I know no one has ever published a book called ‘The Death of Geology’ featuring a hangman’s noose on the cover.[4] Coleman’s compendium of evidence shows conclusively, in case anyone hasn’t been keeping their eyes and ears open, that economics is actively hated by a substantial number of people. There is no other discipline of which this is true, except insofar as some people hate all actual and would-be scientific disciplines from religious, green, or aesthetic motivations.
