This paper evaluates Kuipers' account of functional explanation in biology in view of an example of such an explanation taken from real biology. The example is the explanation of why electric fishes swim backwards (Lannoo and Lannoo 1993). Kuipers' account depicts the answer to a request for functional explanation as consisting only of statements that articulate a certain kind of consequence. It is argued that such an account fails to do justice to the main (...) insight provided by the example explanation, namely the insight into why backwards swimming is needed by fishes that locate their food by means of an electric radar. The paper sketches an improved account that does justice to this kind of insight. It is argued that this account is consistent with and complementary to Kuipers' insight that function attributions are established by means of a process of hypothetico-deductive reasoning guided by a heuristic principle.

Teleological explanations (TEs) account for the existence or properties of an entity in terms of a function: we have hearts because they pump blood, and telephones for communication. While many teleological explanations seem appropriate, others are clearly not warranted-for example, that rain exists for plants to grow. Five experiments explore the theoretical commitments that underlie teleological explanations. With the analysis of [Wright, L. (1976). Teleological Explanations. Berkeley, CA: University of California Press] from philosophy as a point of departure, we examine (...) in Experiment 1 whether teleological explanations are interpreted causally, and confirm that TEs are only accepted when the function invoked in the explanation played a causal role in bringing about what is being explained. However, we also find that playing a causal role is not sufficient for all participants to accept TEs. Experiment 2 shows that this is not because participants fail to appreciate the causal structure of the scenarios used as stimuli. In Experiments 3-5 we show that the additional requirement for TE acceptance is that the process by which the function played a causal role must be general in the sense of conforming to a predictable pattern. These findings motivate a proposal, Explanation for Export, which suggests that a psychological function of explanation is to highlight information likely to subserve future prediction and intervention. We relate our proposal to normative accounts of explanation from philosophy of science, as well as to claims from psychology and artificial intelligence. (shrink)

Mathematical explanations are poorly understood. Although mathematicians seem to regularly suggest that some proofs are explanatory whereas others are not, none of the philosophical accounts of what such claims mean has become widely accepted. In this paper we explore Wilkenfeld’s suggestion that explanations are those sorts of things that generate understanding. By considering a basic model of human cognitive architecture, we suggest that existing accounts of mathematical explanation are all derivable consequences of Wilkenfeld’s ‘functional explanation’ proposal. We (...) therefore argue that the explanatory criteria offered by earlier accounts can all be thought of as features that make it more likely that a mathematical proof will generate understanding. On the functional account, features such as characterising properties, unification, and salience correlate with explanatoriness, but they do not define explanatoriness. (shrink)

Invoking its social function can explain why we find a certain functional trait or institution only if we can identify a mechanism whereby the playing of the function connects with the explanandum. That is the main claim in the missing-mechanism critique of functionalism. Is it correct? Yes, if functional explanation is meant to make sense of the actual presence of the trait or institution. No, if it is meant to make sense of why the trait or institution (...) is resilient: why we can rely on it to survive various contingencies. The lesson? Social functionalism should be taken, and may have been taken by its founders, as a programme for explaining resilience. (shrink)

I argued in Karl Marx's Theory of History that the central claims of historical materialism are functional explanations, and I said that functional explanations are consequence explanations, ones, that is, in which something is explained by its propensity to have a certain kind of effect. I also claimed that the theory of chance variation and natural selection sustains functional explanations, and hence consequence explanations, of organismic equipment. In Section I I defend the thesis that historical materialism offers (...) functional or consequence explanations, and I reject Jon Elster's contention that game theory can, and should, assume a central role in the Marxist theory of society. In Section II I contrast functional and consequence explanation, thereby revising the position of Karl Marx's Theory of History, and I question whether evolutionary biology supports functional explanations. Section III is a critique of Elster's views on functional explanation, and Sections IV and V defend consequence explanation against metaphysical and epistemological doubts. A concluding section summarizes my present understanding of the status of historical materialist explanations. (shrink)

This 2001 book offers an examination of functional explanation as it is used in biology and the social sciences, and focuses on the kinds of philosophical presuppositions that such explanations carry with them. It tackles such questions as: why are some things explained functionally while others are not? What do the functional explanations tell us about how these objects are conceptualized? What do we commit ourselves to when we give and take functional explanations in the life (...) sciences and the social sciences? McLaughlin gives a critical review of the debate on functional explanation in the philosophy of science. He discusses the history of the philosophical question of teleology, and provides a comprehensive review of the post-war literature on functional explanation. What Functions Explain provides a sophisticated and detailed Aristotelian analysis of our concept of natural functions, and offers a positive contribution to the ongoing debate on the topic.

The claim that a functional kind is multiply realized is typically motivated by appeal to intuitive examples. We are seldom told explicitly what the relevant structures are, and people have often preferred to rely on general intuitions in these cases. This article deals with the problem by explaining how to understand the proper relation between structural kinds and the functions they realize. I will suggest that the structural kinds that realize a function can be properly identified by attending to (...) the context of functional explanation. *Received June 2006; revised June 2009. †To contact the author, please write to: Department of Philosophy, Seton Hall University, 400 South Orange Ave., South Orange, NJ 07079; e‐mail: mark.couch@shu.edu.

G. A. Cohen defends and Jon Elster criticizes Marxist use of functional explanation. But Elster's mechanical conception of explanation is, contrary to Elster's claims, a better basis for vindication of functional explanation than Cohen's nomological conception, which cannot provide an adequate account of functional explanation. Elster also objects that functional explanation commits us to metaphysically bizarre collective subjects, but his argument requires an implausible reading of methodological individualism which involves an unattractive (...) eliminativism about social phenomena.

This paper is concerned with the problem of giving a correct analysis of function statements as they are used in biology. Examples of such statements are (1) The function of the myelin sheath is to insulate the nerve fiber and (2) The function of chlorophyll is to enable photosynthesis to take place. After criticizing analyses of such statements developed by Braithwaite, Nagel and Hempel an analysis is presented by the author. Finally the question of whether function statements are explanations is (...) discussed briefly. (shrink)

I adopt a cladistic view of species, and explore the possibility that there exists an equally valuable cladistic view of organismic traits. This suggestion seems to run counter to the stress on functional views of biological traits in recent work in philosophy and psychology. I show how the tension between these two views can be defused with a multilevel view of biological explanation. Despite the attractions of this compromise, I conclude that we must reject it, and adopt an (...) essentially cladistic conception of biological traits. (shrink)

This paper is a critical examination of one central theme in Jon Elster's Making Sense of Marx; Elster's defense of ?methodological individualism? in social science and his related critique of Marx's use of ?functional explanation?. The paper does not quarrel with Elster's claim that the particular instances of functional explanation advanced by Marx are defective; what it criticizes is Elster's attempt to raise principled, philosophical objections to this type of explanation in the social sciences. It (...) is argued that Elster's philosophical critique of functional explanation rests on a caricature of this kind of explanation, just as his critique of Marx's use of teleology in the philosophy of history rests on a caricature of the kinds of teleological claims Marx is concerned to make. The paper ends with a brief discussion of a recently published passage from Marx's notebooks of 1861?1863, where Elster claims to have found Marx explicitly criticizing capitalist exploitation as an injustice to the workers.

From their conception to the present, the social sciences have invoked a kind of explanation that looks suspect by the standards of the natural sciences. They explain why social practices exist by reference to the purpose or needs they serve. Yet the purposes invoked are generally not the explicit purposes or needs of any individual but of society or social groups. For example, Durkheim claimed that the division of labor in society exists in order to promote social solidarity and (...) Marx thought that the state served to promote the interests of the ruling class. Social scientists have found these explanations as irresistible as their critics have found them mysterious. This chapter traces the controversies over these explanations — generally called functional explanations — and argues that they are widespread in some of our best current social science and that they can provide compelling information in some cases, despite the many doubts about them.

Economists seldom make explicit use of functional explanation, although they sometimes use it implicitly. Functional theorizing has lost favour among social scientists in recent years, and few are now willing to adopt functional language. This paper argues that, despite some drawbacks, explicit functional methods have several attractive features, including a pluralistic attitude to causality, an awareness of stratification and emergence, and a compatibility with a realist perspective. Functional methods on their own cannot provide full (...) causal explanations, but they can raise important theoretical issues often neglected in mainstream economics. (shrink)

Review of Peter Mc. Laughlin *What Functions Explain" (2001).

This paper considers two ways functions figure into scientific explanations: (i) via laws?events are causally explained by subsuming those events under functional laws; and (ii) via designs?capacities are explained by specifying the functional design of a system. We argue that a proper understanding of how functions figure into design explanations of capacities makes it clear why such functions are ill-suited to figure into functional-cum-causal law explanations of events, as those explanations are typically understood. We further argue that (...) a proper understanding of how functions enter into design explanations of capacities enables us to show why two prominent objections to functionalism in the philosophy mind?the argument from metaphysically necessary effects (Bennett, 2007; Rupert, 2006) and causal exclusion (Kim, 1993, 1998; Malcolm, 1968)?are misguided when interpreted as posing a threat to functional explanation in science across the board. If those arguments pose a threat at all, they pose it to instances of (i); however, a great number of the functional explanations we find in psychology?and the sciences generally?are instances of (ii).

Cohen employs in his book Karl Marx's Theory of History: A Defense in light of its recent republication. In recent years, Roy Bhaskar has provided a convincing critique of the empiricist philosophy of social science that Cohen employs, and this article tries to provide an assessment of his method from a Bhaskarian perspective. It begins with an exposition of functional explanation, followed by the Bhaskarian critique by demonstrating that functionalism is unworkable because it is dependent on an empiricist (...) account of causation.

Social capital is frequently offered up as a variable to explain such educational outcomes as academic attainment, drop-out rates and cognitive development. Yet, despite its popularity amongst social scientists, social capital theory remains the object of some scepticism, particularly in respect of its explanatory ambitions. I provide an account of some explanatory options available to social capital theorists, focussing on the functions ascribed to social capital and on how these are used as explanatory variables in educational theory. Two of the (...) most influential writers in this field are Coleman and Bourdieu. I explore their commonalities and differences, both in respect of their writing and in respect of some of the many theorists they have influenced. I argue that social capital theorists have made substantial progress in responding to sceptically minded critics, but that significant questions remain, especially about the success of the more ambitious explanatory variants as these apply to educational outcomes—functional explanation in particular. Functional explanation, and its association with Bourdieu, is discussed in ‘Bourdieu and functional explanation’; thereafter I discuss the more modest ambition of identifying the functions associated with social capital. In ‘Coleman, intergenerational closure and educational outcomes’ I show how Coleman provides resources for revealing how social structure features in social explanation in an educational context, and in ‘Inequality, class and ethnicity’ I suggest that some of the questions raised in his account are most satisfactorily responded to by educational theorists who adopt Bourdieu’s emphasis on social class and inequality.

Functional explanations are regarded as a special type of explanation by many biologists. Philosophers of science tend to agree that they are weak forms of the common modes of explanation, although the elucidation of the logical structure involved is difficult. The present paper shows that Hempel's reconstruction of functional explanations is inadequate on pragmatic grounds. Thus his conclusion that such explanations are necessarily weak is also objectionable. There is no reason for allotting functional explanations a (...) special logical status. (shrink)

In this paper, I argue that explanations just ARE those sorts of things that, under the right circumstances and in the right sort of way, bring about understanding. This raises the question of why such a seemingly simple account of explanation, if correct, would not have been identified and agreed upon decades ago. The answer is that only recently has it been made possible to analyze explanation in terms of understanding without the risk of collapsing both to merely (...) phenomenological states. For the most part, theories of explanation were for 50 years held hostage to the historical accident that they far outstripped in sophistication corresponding accounts of understanding. (shrink)

Jon Elster and Daniel Little have criticized social scientists for appealing to a mechanism of social selection in functional explanations of social practices. Both believe that there is no such mechanism operative in the social world. I develop and defend an account of functional explanation in which a mechanism of social selection figures centrally. In addition to developing an account of social selection, I clarify what functional hypotheses purport to claim, and re-examine the role of agents, (...) intentions in functional explanations in an effort to show why a mechanism of social selection is indispensable to adequate functional explanations.

Agent causation presupposes that actions are behaviors under the causal control of the agent’s mental states, its beliefs and desires. Here the idea of conscious causation in causal explanations of actions is examined, specifically, actions said to be the result of conscious efforts. Causal–functionalist theories of consciousness purport to be naturalistic accounts of the causal efficacy of consciousness. Flanagan argues that his causal–functionalist theory of consciousness satisfies naturalistic constraints on causation and that his causal efficacy thesis is compatible with results (...) of Libet’s experiments on conscious causation. First, the notions of conscious effort and conscious causation are analyzed with respect to the project of naturalizing the mind, that is, the attempt to assimilate folk-psychological explanation to the causal model of explanation in the natural sciences. It is argued that a serious obstacle for any naturalist program is that mental states are individuated by their semantic content, not the mechanistic, physical properties of their neural state instantiations. In particular, it is argued that explanation by reference to mental state content yields not a causal but an interpretive or rationalizing account of action in which the question of causal efficacy is irrelevant. Then, Flanagan’s causal–functionalist theory of consciousness is critically assessed; specifically his interpretations of Libet’s negative experimental results on the causal efficacy of consciousness are diagnosed and disputed. It is contended that Flanagan misinterprets the results of Libet’s consciousness experiments and that his functionalist concept of consciousness fails to yield an adequate explanation of the alleged causal efficacy of consciousness. Finally, his thesis is countered with other experimental results that appear to favor an epiphenomenalist view over the causal efficacy account of consciousness. (shrink)

There is an argument for functionalism—and _ipso facto_ against identity theory—that can be sketched as follows: We are, or want to be, or should be dedicated to functional explanations in the sciences, or at least the special sciences. Therefore—according to the principle that what exists is what our ideal theories say exists—we are, or want to be, or should be committed to metaphysical functionalism. Let us call this the _argument from functional_ _explanation_. I will try to reveal the motivation (...) for making such an argument, and sketch the kind of response that should be made by critics of functionalism. (shrink)

Piccinini and Craver (Synthese 183:283–311, 2011) argue for the surprising view that psychological explanation, properly understood, is a species of mechanistic explanation. This contrasts with the ‘received view’ (due, primarily, to Cummins and Fodor) which maintains a sharp distinction between psychological explanation and mechanistic explanation. The former is typically construed as functional analysis, the analysis of some psychological capacity into an organized series of subcapacities without specifying any of the structural features that underlie the explanandum (...) capacity. The latter idea, of course, sees explanation as a matter of describing structures that maintain (or produce) the explanandum capacity. In this paper, I defend the received view by criticizing Piccinini and Craver’s argument for the claim that psychological explanation is not distinct from mechanistic explanation, and by showing how psychological explanations can possess explanatory force even when nothing is known about the underlying neurological details. I conclude with a few brief criticisms about the enterprise of mechanistic explanation in general. (shrink)

Functions: selection and mechanisms is a collection of eleven original contributions to the philosophical debates surrounding functions. In the words of Philippe Huneman, editor of the volume, the aim of the book is to reflect “upon the metaphysics of function and the various problems that functional explanations raise” . This is accomplished by a diverse collection of chapters that focus on various aspects of the main topic. A collection such as this is certainly welcome. As Huneman notes in his (...) introduction, where he helpfully summarises the various contributions and introduces the reader to the philosophical debates about functions, there are several advances in recent philosophy of science that necessitate a re-evaluation of the positions regarding functions. Central among them are the rich literature on mechanisms, as well as recent developments within biology and philosophy of biology. The chapters are organised i .. (shrink)

How questions and why questions interact in complex ways within biological practice. One of the most fruitful accounts to think about this relation is the widely known systemic approach, which has its origin mainly in the works of Robert Cummins (1975, 1983). As we will show, this approach effectively manages to capture much of what biologists do, especially in areas such as molecular biology, neuroscience and neuroethology. Our aim with this work is to discuss the metatheoretical status of the presuppositions (...) behind systemic analysis. We will hold that these assumptions are of an empirical nature, and that they can be reconstructed as parts of a theory. (shrink)

In the Passion of the Soul Descartes sets out to explain the origins and structure of intentional voluntary action, to give an account of physical behavior and motion that has psychological and intellectual causes.Actually of course this is not at all what he says. He announces an analysis of the passions of the soul. But why does he define his subject as he does? His correspondence had forced a concern with questions of virtue. How is he to introduce an account (...) of virtue in his metaphysically, scientifically oriented philosophy of mind, a theory which must accommodate his normative epistemology on one hand and his mechanistic physiological psychology on the other? Other pressures forced closely related questions. Just what is the character of the ‘substantial’ union of mind and body? What is the psychological status of perception, and what are the relations among various types of perceptions? It is these questions that Descartes sets out to answer. (shrink)
