The philosophy of economic modelling: a critical survey

Economic modelling, the heart of orthodox economics, has long been accused of neglecting the interpretation of its models needed to generate knowledge claims about the real world. It is argued that recent developments in the philosophy of model and theory can help us to evaluate the scientific and policy relevance of economic models. McCloskey's attempt to finesse this issue by reference to the rhetoric of economics is argued not to be congruent with economics' revealed explanatory and policy objectives. Blaug's adherence to a Popper-Lakatos mode of appraisal may be a little dated, but none of the more recent approaches to the metaphysical foundations of economics—such as scientific realism, constructive empiricism or 'causal holism'—seem able to rebuff the criticism explicit and implicit in the recent work of, for example, Hausman and Rosenberg. An example of 'modelling without theory' and Rapport's recent defence of economic modelling's practice suggest the need for further detailed evaluation by case-studies of the development and application of economic models.     

The methodology of genuine modal realism

David Lewis’s genuine modal realism is a controversial thesis in modal metaphysics. Charles Chihara and Ross Cameron have each argued that Lewis’s defence of his thesis involves his committing serious methodological errors; in particular, that his replies to two well-known and important objections are question-begging. Scott Shalkowski has further argued that Lewis’s attempt to analyse modal talk in non-modal terms is viciously circular. This paper considers the methodology which Lewis uses to argue for his thesis, and the paper tries to show that it is guilty of no methodological errors.     

Shadworth Hodgson and William James's formulation of space perception: Phenomenology and perceptual realism

This paper has two related goals. First, it seeks to show that the theory of perception found in William James's Principles of Psychology is thoroughly consistent if it is approached through the framework of perceptual realism versus constructionism rather than the nativism versus empiricism debate. As such, this paper offers an alternative to Nicholas Pastore's claim that there are two contradictory theories of perception in the Principles. James's commitment to perceptual realism is articulated within the contexts of his (1) critique of constructionist perception theories, (2) notion of the spatial quale, and (3) formulation of the role of knowledge in adult perception. The second goal of this paper deals with the historical development of James's perceptual realism. Here it is argued that Shadworth Hodgson's method of reflection–an anticipation of Husserl's phenomenological reduction–served as the basis of James's commitment to perceptual realism.     

Global government or global governance? Realism and idealism in Kant's legal theory

Did Kant believe we need a world government? It has been a matter of controversy in Kant scholarship whether Kant endorsed the creation of a world state or merely a voluntary federation of states with no coercive power. I argue that Kant's main concern was with a global juridical condition, which he regarded as a rational requirement given the equal freedom and equality of individuals. However, he recognized that implementing this rational ideal requires sensitivity to contingent aspects of world politics. I will argue that Kant offers an ideal theory not disentangled from realist considerations and that he adopts what I will call methodological realism: the attempt to realize the requirements of Right (Recht) in a world governed by its own laws and mechanisms. I will illustrate this interpretation with Kant's discussion of the right of nations (Völkerrecht). The confusion in regard to Kant's actual position on the matter, I will argue, is a direct consequence of Kant's methodological realism. The article concludes by showing how Kant’'s ideas and methods can inspire us to rethink global institutions for our current global challenges.     

Structural Realism, Scientific Change, and Partial Structures

Scientific change has two important dimensions: conceptual change and structural change. In this paper, I argue that the existence of conceptual change brings serious difficulties for scientific realism, and the existence of structural change makes structural realism look quite implausible. I then sketch an alternative account of scientific change, in terms of partial structures, that accommodates both conceptual and structural changes. The proposal, however, is not realist, and supports a structuralist version of van Fraassen’s constructive empiricism (structural empiricism).     

Lewisian Realism: Methodology,Epistemology, and Circularity

In this paper I argue that warrant for Lewis’ Modal Realism is unobtainable. I consider two familiar objections to Lewisian realism – the modal irrelevance objection and the epistemological objection – and argue that Lewis’ response to each is unsatisfactory because they presuppose claims that only the Lewisian realist will accept. Since, I argue, warrant for Lewisian realism can only be obtained if we have a response to each objection that does not presuppose the truth of Lewisian realism, this circularity is vicious. I end by contrasting Lewis’ methodology with Forrest’s in order to illustrate a rival method that does not fall victim to the objection I lay against Lewis.     

Wide reflective equilibrium as a method of justification in bioethics

Carson Strong has recently argued that wide reflective equilibrium (WRE) is an unacceptable method of justification in bioethics. In its place, Strong recommends a methodology in which certain foundational moral judgments play a central role in the justification of moral beliefs, and coherence plays a limited justificatory role in that the rest of our judgments are made to cohere with these foundational judgments. In this paper, I argue that Strong??s chief criticisms of WRE are unsuccessful and that his proposed alternative is in fact just another version of WRE. In the course of doing so, I specify which theses are central to WRE and which are not, and thus, provide a response to an additional objection, advanced by Peter Singer, that WRE is vacuous. I conclude by arguing that there may be better prospects for advancing the debate regarding methodology in bioethics if we focus on restricted epistemic and methodological theses rather than broad approaches, such as WRE, that come in many different varieties.     

Mathematical models in Newton's Principia: A new view of the ‘Newtonian Style’

In this essay I argue against I. Bernard Cohen's influential account of Newton's methodology in the Principia: the ‘Newtonian Style’. The crux of Cohen's account is the successive adaptation of ‘mental constructs’ through comparisons with nature. In Cohen's view there is a direct dynamic between the mental constructs and physical systems. I argue that his account is essentially hypothetical‐deductive, which is at odds with Newton's rejection of the hypothetical‐deductive method. An adequate account of Newton's methodology needs to show how Newton's method proceeds differently from the hypothetical‐deductive method. In the constructive part I argue for my own account, which is model based: it focuses on how Newton constructed his models in Book I of the Principia. I will show that Newton understood Book I as an exercise in determining the mathematical consequences of certain force functions. The growing complexity of Newton's models is a result of exploring increasingly complex force functions (intra‐theoretical dynamics) rather than a successive comparison with nature (extra‐theoretical dynamics). Nature did not enter the scene here. This intra‐theoretical dynamics is related to the ‘autonomy of the models’.     

Economics Weak and Strong: Ecological Economics and Human Survival

Mounting evidence suggests that the human impact on the planet is reaching the point where the Earth's ecosystems will not be able to support the level of human occupation. The global economy also seems to be generating income disparities that threaten the social stability of even the most developed economies. Although both these trends are rooted in the operation of the global market economy, standard economics has surprisingly little to offer in the way of policies that might allow us to survive the twenty-first century with our current social and environmental systems intact. This article examines our current predicament from the point of view of neoclassical welfare economics and the alternative framework of ecological economics. We argue that ecological economics, by placing the study of economics squarely within human society and ecosystems, can lead the way to make economics both scientifically credible and policy relevant.     

Empirical tests of scientific realism: A quantitative framework

The scientific realism debate in philosophy of science raises some intriguing methodological issues. Scientific realism posits a link between a scientific theory's observational and referential success. This opens the possibility of testing the thesis empirically, by searching for evidence of such a link in the record of theories put forward in the history of science. Many realist philosophers working today propose case study methodology as a way of carrying out such a test. This article argues that a qualitative method such as case study methodology is not adequate for this purpose, for two reasons: to test scientific realism is to pose an effects-of-causes question, and observational and referential success are quantities that theories possess to a greater or lesser degree. The article concludes that an empirical test of scientific realism requires a quantitative method.     

The Soteriology of Role-Play in the Bhagavad Gītā

I will here apply the classical Indian model of the dramatic actor as a methodology for interpreting the soteriological psychology of the Bhagavad Gītā, paying special attention to the usefulness of this approach for clarifying K???a's rationale in showing his divine form in Chapter 11. I argue that the Gītā advocates creative role-play as both the means and the end of liberation. Further, while K???a's teachings can be understood in terms of orthodox Hindu soteriologies that have in view an overcoming of the emotions, I argue that K???a looks to transform Arjuna into an ‘athlete of emotion’, much like traditional Indian-based training methods do for theatrical actors.     

Normative naturalism and the challenge of relativism: Laudan versus Worrall on the justification of methodological principles

In Science and Values, Larry Laudan argues that rational scientific change is not restricted to scientific theory, but may also affect the methodology and axiology of science. In subsequent debate, John Worrall has raised the question of whether invariant principles of methodology are necessary in order to avoid epistemological relativism. Worrall argues that Laudan's denial of such principles leads straight to relativism. By contrast, Laudan claims that, rather than methodological invariance, what is required to escape relativism is a rational justification of such principles. In this paper, it will be argued that the normative naturalist meta‐methodology, which Laudan has developed in work subsequent to Science and Values, contains the resources needed to mount a satisfactory response to Worrall's charge of relativism.     

Campaign Contributions,Post-War Reconstruction Contracts,and State Crime

This article presents a case-control study of the relationship between Federal-level campaign contributions, corporate political connections, and the awarding of post-war reconstruction contracts in Iraq and Afghanistan. Cases are 135 companies that received post-war contracts and controls are 135 randomly selected companies matched on industry. Results reveal that both campaign contributions and political connections significantly increase a company's odds of receiving a contract. Results are situated in the context of current theory on state crime. It is argued that awarding contracts on this basis may constitute a form of state crime, but alternative explanations for the findings are also discussed.     

Reflective equilibrium and moral objectivity

Ever since the introduction of reflective equilibrium in ethics, it has been argued that reflective equilibrium either leads to moral relativism, or that it turns out to be a form of intuitionism in disguise. Despite these criticisms, reflective equilibrium remains the most dominant method of moral justification in ethics. In this paper, I therefore critically examine the most recent attempts to defend the method of reflective equilibrium against these objections. Defenders of reflective equilibrium typically respond to the objections by saying that either reflective equilibrium can in fact safeguard moral objectivity or alternatively, even if it cannot, that there simply are no reasonable alternatives. In this paper, I take issue with both responses. First, I argue that given the non-foundationalist aspirations of reflective equilibrium, moral objectivity cannot be maintained. Second, I argue that reflective equilibrium is not the only game in town once intuitionism has been discarded. I argue that given their own normative ambitions, combined with their rejection of intuitionism, proponents of reflective equilibrium have reason to take alternative methods of moral justification, and more specifically transcendental arguments, more seriously than they have done so far. I end by sketching the outlines of what this alternative methodology might look like.     

The Truth of the Matter

Feminist standpoint theory (FST) has a troubled history that has limited its use and development as a core feminist epistemological project. This article revisits debates from its past, and re‐examines an apparent central problem: that of the realism identifiable in FST. Looking closely at the criticism leveled against one particular standpoint theorist—Nancy Hartsock—I show the criticism not only to be unfounded, as has previously been argued, but also unnecessary. I demonstrate that the accusations of supposedly realist contradictions in Hartsock's work are easily resolvable by engagement with critical realism (CR). I argue that CR not only accommodates Hartsock's conception of realism, and so dissolves any contention, but that CR complements and shores up FST's central claim: that situated knowledge carries with it an epistemic privilege. Another contemporary conception of realism is being developed—New Materialism (NM)—that, it could be argued, would also be a suitable ontology with which to develop FST. I show how NM could present problems for FST as a fundamentally political project, and conclude that CR offers a more fruitful future collaboration for FST.
