The etiological account of teleological function is beset by several difficulties, which I propose to solve by grafting onto the etiological theory a subordinated goal-contribution clause. This approach enables us to ascribe neither too many teleofunctions nor too few; to give a unitary, one-clause analysis that works just as well for teleological functions derived from Darwinian evolution, as for those derived from human intention; and finally, to save the etiological theory from falsification, by explaining how, in spite of appearances, the (...) theory can allow for evolutionary function loss.

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)

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.

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)

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.

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)

In this essay I defend functional explanations in sociobiology against the charge that they are exercises in speculative story-telling. I distinguish proximate and ultimate biological functions, and discuss their role in functional explanations. I characterize functional explanations as a kind of "consequence explanation", and argue that sociobiologists need to justify a "functional fact" in addition to a "consequence law". Two methods used to supply evidence for functional hypotheses, the technique of optimality analyses and the (...) comparative method, are discussed and illustrated with examples. I argue that adequate evidence for hypothesis about the function of a trait can be provided by the method of comparison, but not by optimality analyses. The comparative method contains an inductive phase that provides independent warrant for, and so serves to establish the high probability of, functional hypotheses. Independent warrant cannot be provided by optimality analyses alone: the model-building approach itself mandates the sacrifice of the truth of a hypothesis to its predictive power. I conclude that while the sociobiologist may wish to employ the optimality analysis as a heuristic strategy, reliable functional explanations are better sought through the use of the comparative method.

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.

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)

In this paper, I try to develop an account of functions which might be of use to a biologist engaged in classifying and explaining natural phenomena. The most pressing difficulty facing such an account is the need to reconcile the normativity of function statements with their explanatory force. I consider two familiar accounts of function statements, offered by Andrew Woodfield and Larry Wright . I examine both accounts in search of the strongest possible formulation of each type of theory. I (...) fail to find a formulation of the ACT which is completely immune from counterexamples, but I do find a satisfactory formulation of the HT. In particular, I argue that the HT should incorporate a point central to the ACT that functions involve a means/end relationship between two devices. I then consider functional explanations: I argue that an ACT which holds that function statements are intrinsically explanatory cannot offer a satisfactory account. The account offered by Woodfield, who rejects this assumption, is adequate, though less attractive than the account suggested by the HT. I conclude by considering how the HT can account for functional norms. (shrink)

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: [email protected].

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)

Functionalism is a dominant but widely criticized perspective in social theory; my goal in this paper is to help clarify what functionalists claim, identify what would count as evidence for those claims and evaluate some standard criticisms. Functionalism relies essentially on functional explanations of the form "A exists in order to B." I point out problems with previous accounts of such explanations, offer an improved account, and discuss in detail evidence that might confirm such explanations and its difficulties. I (...) argue that some functionalist accounts can be confirmed and that, contra the critics, functionalism's problems are not inherent errors, "only" practical ones. (shrink)

Despite decades of controversy, functionalism continues to be a lively research tradition in the social sciences. Furthermore, social scientists who reject Parsonian functionalism and its variants frequently make liberal use of functional explanations. Yet, neither social scientists nor philosophers have reached any consensus on when and where functional accounts are legitimate. Critics doubt that functionalism is really explanatory or testable; advocates are unfortunately vague on their claims and the evidence for them. In what follows I try to clarify (...) what functionalism entails, discuss some ways in which functional hypotheses can be confirmed, and evaluate criticisms. While I think much functionalism is bad science, I hope to show that the problem is not one of principle but of practice.Social scientists use the term “functionalism” in diverse ways. At times the term refers to a specific theoretical movement in sociology and anthropology—the movement identified with Malinowski and Parsons. (shrink)

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.

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.

If we assume that a conceptual connection does hold between reasons and action, the arguments for both theses are strikingly simple. In defense of the first thesis, all that need be added is Hume's Principle: between cause and effect only a (logically) contingent relation holds. For given Hume's Principle, and the conceptual connection (which after all is not a contingent one), it follows that no causal connection holds. In defense of the second thesis, all that need be added is one (...) assumption and one observation. The assumption is that the covering-law model of explanation is adequate to the natural sciences; the observation is that if a conceptual connection does hold, then covering-laws are not required to explain a person's action given the presence of the relevant beliefs and desires (because the presence of the latter entail the performance of the former). Together the assumption and the observation undermine the view that one model of explanation will fit both natural science and human psychology. (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 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).

A series of explanatory hypotheses are examined under the assumption that the logical structure of function attributions is dependent on the methodological constraints which these hypotheses conform to. Two theses are argued for: (1) Given these methodological constraints, if something has the function of doing Y, then normally it is the only kind of thing that can do Y in that kind of system. (2) What distinguishes function attributions from causal attribution is not that function attributions explain the etiology of (...) the causally efficacious object, as Wright has suggested. The distinction lies rather in that the object's having the effect, which is attributed to it as its function, must figure in the explanation of why it does what it does to achieve that effect.

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.

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)

Do functional explanations eclipse the intentionality of human actions? Put differently, do intentional and functional explanations of actions conflict with each other? In this paper, I want to argue that both sorts of explanation, if conceived in a proper way, are compatible instruments. First, I will make a distinction between three kinds of explanatory pluralism of actions: a pluralism of theories of actions, a pluralism of sorts of explanations of actions, and a pluralism of methods for the (...) explanation of actions. Intentional and functional explanations are sorts, not theories or methods, of explanation. Next, I will briefly distinguish intentional and functional explanations: intentional explanations refer to the beliefs and desires of an agent, and functional explanations refer to the function of a motive of an action (etiological functions), or to the function of a result of an action (system functions). Finally, I discuss possible conflicts between both sorts of explanation. In cases where real conflicts between functional and intentional explanations do arise, this is due to the lack of sufficient information or the misinterpretation of information of one or both explanations. Hence, such conflicts are not conflicts between sorts of explanations. (shrink)

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)

This paper: (1) gives a schema of the logical structure of functional explanation in biology; (2) shows that it falls under the covering law model of explanation by proving that the explanandum follows from the explanans; and (3) supports the claim that it captures the logical structure underlying the biological usage by analyzing in detail two cases from biology.

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.

While many philosophers speak of ‘pluralism’ within philosophy of biology, there has been little said about what such pluralism amounts to or what its underlying assumptions are. This has provoked so me anxiety about whether pluralism is compatible with their commitment to naturalism. This paper surveys three prominent pluralist positions ‘integrative pluralism’, and both Peter Godfrey-Smith’s and Beth Preston’s pluralist analyses of functional explanations in evolutionary biology) and demonstrates how all three are committed to a form of pragmatism. This (...) analysis both clarifies the justification and grounding of pluralism and allows these pluralisms to avoid the criticisms of Cussins. I close by making some more general points about pluralism and its relationship to history and integration. (shrink)

The ability to generalize from the known to the unknown is central to learning and inference. Two experiments explore the relationship between how a property is explained and how that property is generalized to novel species and artifacts. The experiments contrast the consequences of explaining a property mechanistically, by appeal to parts and processes, with the consequences of explaining the property functionally, by appeal to functions and goals. The findings suggest that properties that are explained functionally are more likely to (...) be generalized on the basis of shared functions, with a weaker relationship between mechanistic explanations and generalization on the basis of shared parts and processes. The influence of explanation type on generalization holds even though all participants are provided with the same mechanistic and functional information, and whether an explanation type is freely generated (Experiment 1), experimentally provided (Experiment 2), or experimentally induced (Experiment 2). The experiments also demonstrate that explanations and generalizations of a particular type (mechanistic or functional) can be experimentally induced by providing sample explanations of that type, with a comparable effect when the sample explanations come from the same domain or from a different domains. These results suggest that explanations serve as a guide to generalization, and contribute to a growing body of work supporting the value of distinguishing mechanistic and functional explanations.

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)

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)
