This paper argues that there are powerful similarities between cognitive development in children and scientific theory change. These similarities are best explained by postulating an underlying abstract set of rules and representations that underwrite both types of cognitive abilities. In fact, science may be successful largely because it exploits powerful and flexible cognitive devices that were designed by evolution to facilitate learning in young children. Both science and cognitive development involve abstract, coherent systems of entities and rules, theories. In both (...) cases, theories provide predictions, explanations, and interpretations. In both, theories change in characteristic ways in response to counterevidence. These ideas are illustrated by an account of children's developing understanding of the mind. (shrink)

Taking reduction in the traditional deductive sense, the programmatic claim that most of genetics can be reduced by molecular genetics is defended as feasible and significant. Arguments by Ruse and Hull that either the relationship is replacement or at best a weaker form of reduction are shown to rest on a mixture of historical and logical confusions about the nature of the theories involved.

Homology continues to be a concept of central importance in the study of phylogenetic relations, but its relation to ontogenetic processes remains problematical. A definition of homology in terms of equivalent morphogenetic processes is defined and applied to the comparative study of tetrapod limbs. This allows for a consistent treatment of relations of similarity and difference of appendage structure in vertebrates, and the distinction between fishes fins and tetrapod limbs in terms of the concept of equivalence is described. The role (...) of genes can also be clarified in this context, in particular the influence of the Hox 4 complex in determining digit character and the homeotic transformations that arise from changes in their expression patterns. It is argued that these observations are not compatible with the notion of homology between individual digits (I, II, III, etc.) across the tetrapods, and that homology cannot be consistently identified with gene action. The relations between homology and the properties of the morphogenetic limb field are discussed. (shrink)

Maynard Smith is right that one of the most striking features of contemporary biology is the ever-increasing prominence of the concept of information, along with related concepts like representation, programming, and coding. Maynard Smith is also right that this is surely a phenomenon which philosophers of science should examine closely. We should try to understand exactly what sorts of theoretical commitment are made when biological systems are described in these terms, and what connection there is between semantic descriptions in biology (...) and in other domains.

In this paper I offer an analysis of causation based upon a theory of mechanisms-complex systems whose internal parts interact to produce a system's external behavior. I argue that all but the fundamental laws of physics can be explained by reference to mechanisms. Mechanisms provide an epistemologically unproblematic way to explain the necessity which is often taken to distinguish laws from other generalizations. This account of necessity leads to a theory of causation according to which events are causally related when (...) there is a mechanism that connects them. I present reasons why the lack of an account of fundamental physical causation does not undermine the mechanical account. (shrink)

My concern is with the possible implications of research in developmental psychology for understanding the workings of modern science. I agree both with Gopnik's general naturalistic orientation and with her more specific claims about scientists as cognitive agents. Neither the formal structure of propositions nor the social structure of scientific communities provides sufficient resources for the understanding we seek. So I agree that the empirical study of human cognition is not only relevant, but necessary, for understanding how science works.

Alexander Rosenberg recently claimed (1997) that developmental biology is currently being reduced to molecular biology. cite several concrete biological examples that are intended to impugn Rosenberg's claim. I first argue that although Laubichler and Wagner's examples would refute a very strong reductionism, a more moderate reductionism would escape their attacks. Next, taking my cue from the antireductionist's perennial stress on the importance of spatial organization, I describe one form an empirical finding that refutes this moderate reductionism would take. Finally, I (...) point out an actual example, anterior-posterior axis determination in the chick, that challenges the reductionist's belief that all developmental regularities can be explained by molecular biology. In short, I argue that Rosenberg's position can be saved from Laubichler and Wagner's criticisms and putative counter-examples, but it would not survive a different kind of counter-example. (shrink)

This book is largely a reconsideration of the arguments that are supposed to ground this consensus.

A certain ‘pragmatist’ view of concept possession has defined the mainstream of Anglophone philosophy of language/mind for decades: namely, that to have the concept C is to be able to distinguish Cs from non‐Cs, and/or to recognize the validity of certain C‐involving inferences. The present paper offers three arguments why no such account could be viable. An alternative ‘Cartesian’ view is outlined, according to which having C is being able to think about Cs ‘as such’. Some consequences of the proposed (...) paradigm shift are briefly considered. (shrink)

Consider the task under which I labour: These are supposed to be talks in the millennial spirit. My charge is to find, somewhere in the philosophical landscape, a problem of whose current status I can give some coherent account, and to point the direction in which it seems to me that further research might usefully proceed, And I'm to try to sound reasonably cheerful and optimistic in the course of doing so. No sooner did I begin to ponder these terms (...) of engagement, than it occurred to me that cheer and optimism aren't really my thing; also that I hadn't heard of a topic in the philosophy of mind which seems to me to be other than a godawful mess. It struck me that my best course would be for me to change my name and go into hiding. Thus my first choice of a title for this lecture, which was ‘To Be Announced’. (shrink)

The renowned philosopher Jerry Fodor, a leading figure in the study of the mind for more than twenty years, presents a strikingly original theory on the basic constituents of thought. He suggests that the heart of cognitive science is its theory of concepts, and that cognitive scientists have gone badly wrong in many areas because their assumptions about concepts have been mistaken. Fodor argues compellingly for an atomistic theory of concepts, deals out witty and pugnacious demolitions of rival theories, and (...) suggests that future work on human cognition should build upon new foundations. This lively, conversational, and superbly accessible book is the first volume in the Oxford Cognitive Science Series, where the best original work in this field will be presented to a broad readership. Concepts will fascinate anyone interested in contemporary work on mind and language. Cognitive science will never be the same again. (shrink)

Child's play? Certainly Alison Gopnik is in good company in pointing to connections between science and child development. To mention just a few luminaries: in psychology, Freud looked at the developmental connection between children's play and adult work; in philosophy, Thomas Reid may have been the first to ground the faculty of reasoning in developmental stages that “unfold themselves by degrees; so that it [the child] is inspired with the various principles of common sense”. As for connecting commonsense reasoning and (...) science, according to Einstein, “The whole of science is nothing more than a refinement of everyday thinking”. Quod erat demonstrandum. (shrink)

Species pluralism gives us reason to doubt the existence of the species category. The problem is not that species concepts are chosen according to our interests or that pluralism and the desire for hierarchical classifications are incompatible. The problem is that the various taxa we call 'species' lack a common unifying feature.

In the first section of this paper I present a well known objection to meaning holism, according to which holism is inconsistent with natural language being learnable. Then I show that the objection fails if language acquisition includes stages of partial grasp of the meaning of at least some expressions, and I argue that standard model theoretic semantics cannot fully capture such stages. In the second section the above claims are supported through a review of current research into language acquisition. (...) Finally, in the third section it is argued that contemporary algebraic logical systems consist in a superior formal vehicle through which to capture stages of partial grasp of meaning; this claim is supported by concrete examples.

In this paper I assess Gopnik and Meltzoff's developmental psychology of science as a contribution to the understanding of scientific development. I focus on two specific aspects of Gopnik and Meltzoff's approach: the relation between their views and recapitulationist views of ontogeny and phylogeny in biology, and their overall conception of cognition as a set of veridical processes. First, I discuss several issues that arise from their appeal to evolutionary biology, focusing specifically on the role of distinctions between ontogeny and (...) phylogeny when appealing to biology for theoretical support. Second, I argue that to presuppose that cognition is veridical or "truth-tropic" can compromise attempts to understand scientific cognition both throughout history and in the present. Finally, I briefly sketch an evolutionary approach to understanding scientific development that contrasts with Gopnik and Meltzoff's. (shrink)

Definite descriptions, I shall argue, have two possible functions. 1] They are used to refer to what a speaker wishes to talk about, but they are also used quite differently. Moreover, a definite description occurring in one and the same sentence may, on different occasions of its use, function in either way. The failure to deal with this duality of function obscures the genuine referring use of definite descriptions. The best known theories of definite descriptions, those of Russell and Strawson, (...) I shall suggest, are both guilty of this. Before discussing this distinction in use, I will mention some features of these theories to which it is especially relevant. (shrink)

That no member of a natural kind can switch kinds is a consequence of David Wiggins’ view that the identity conditions for such things are given by the natural kind itself. If dog is a natural kind, then dogs must be dogs and one dog cannot ‘turn into’ something else, say, by gradually ‘becoming’ a mass of tissue (as Marjorie Price had held). Were such a transition to involve the persistence of the same thing, then the thing in question would (...) comply with conditions of identity not restricted to dogs. To provide for such transitions James Baillie suggests alternative conditions of identity, based on Andrew Brennan’s notion of ‘survival’ (itself borrowed from Parfit). Survival requires that the earlier thing be ‘structurally similar to’, and ‘play a significant and direct role in the production of’ the later thing (sufficiency is gained if, in addition, they are composed of the same kind of matter). Unlike identity, however, survival is what Wiggins calls a ‘branching’ relation, capable of linking a single thing with two or more equal ‘competitors’ (as apparently happens in cases of brain fission). To provide conditions of identity per se, Baillie follows Parfit, who claimed that our identity is preserved by psychological continuity when there is no branching. Members of natural kinds, such as dogs, are now said to be reidentifiable over time by the relation of non-branching survival. I argue against this on the ground that we can know when this relation obtains only when we are already able to individuate things by a different sort of relation, such as those associated with natural kinds.

In their discussion of semantic holism, Fodor and Lepore claim that Quine showed that any inferential properties constituting a meaning cannot be distinguished on epistemic grounds like apriority. But they often write as if Quine showed that such properties cannot be distinguished at all. The paper argues that Quine did not show the latter. It goes on to propose a criterion for distinguishing the constitutive properties: they are the ones that determine reference. Fodor is not in a position to reject (...) this criterion since he already uses an analogous one in his own theory. (shrink)

At its most extreme, semantic holism is the doctrine that all the inferential properties of an expression constitute its meaning. Holism is supported by the consideration that there is no principled basis for localism's distinction among these properties. The paper rejects four arguments for this. (1) The argument from confirmation holism is dismissed quickly because it rests on verificationism. (2) The argument from the rejection of analyticity fails because it saddles the localist with unacceptable epistemic assumptions. Localism is not committed (...) to a priori knowledge or to knowledge that is in any interesting sense unrevisable. (3) The argument from psychological explanation fails because it begs the question. (4) The argument from functionalism needs to be accompanied by a further argument that functionalism is essentially holistic. In any case it could only establish a very mild holism. (shrink)

The Philosophical search for Natural Kinds is motivated by the hope of finding ontological categories that are independent of our interests. Other requirements, of varying importance, are commonly made of kinds that claim to be natural. But no such categories are to be found. Virtually any kind can be termed ‘natural’ relative to some set of interests and epistemic priorities. Science determines those priorities at any particular stage of its progress, and what kinds are most ‘natural’ in that sense is (...) always a real and lively scientific question. The general philosophical problem of scientific realism is also real; but between the scientific and the metaphysical, the ‘Problem of Natural Kinds’ sits otiose. (shrink)

In this book Ron Amundson examines two hundred years of scientific views on the evolution-development relationship from the perspective of evolutionary developmental biology. This perspective challenges several popular views about the history of evolutionary thought by claiming that many earlier authors had made history come out right for the Evolutionary Synthesis. The book starts with a revised history of nineteenth-century evolutionary thought. It then investigates how development became irrelevant with the Evolutionary Synthesis. It concludes with an examination of the contrasts (...) that persist between mainstream evolutionary theory and evo-devo. This book will appeal to students and professionals in the philosophy and history of science, and biology. (shrink)

Historically, naturalists who propose theories of evolution, including Darwin and Wallace, have done so in order to explain the apparent relationship of natural classification. This book begins by exploring the intimate historical relationship between patterns of classification and patterns of phylogeny. It is a circular argument, however, to use the data for classification and the concept of homology as evidence for evolution, when evolution is the theory explaining the phenomenon of natural classification. Alec Panchen presents other evidence for evolution in (...) the form of a historically-based but rigorously logical argument. This is then followed by a history of methods of classification and phylogeny reconstruction including current mathematical and molecular techniques. The author makes the important claim that if the hierarchical pattern of classification is a real phenomenon, then biology is unique as a science in making taxonomic statements. This conclusion is reached by way of historical reviews of theories of evolutionary mechanism and the philosophy of science as applied to biology. (shrink)
