Many think that the perceptual theory known as “conceptualism” cannot honor a common and intuitive constraint on concept acquisition—that we gain the initial power to deploy primitive concepts through experience. Their argument is: if experience involves the deployment of concepts, then one must possess the power to deploy those concepts prior to experience. I argue that the plausibility of this argument rests on a subtle equivocation. It’s true that conceptualism requires a particular kind of power to deploy concepts (...) prior to experience, but not the sort referenced in the intuitive constraint mentioned above. I end by proposing how the conceptualist might satisfy this constraint. I conclude that conceptualism is better situated to account for primitive concept acquisition than typically thought. (shrink)

This essay adjudicates between theoretical models of psychological concept acquisition. I provide new reasons to be skeptical about both simulationist and modularist models. I then defend the scientific-theory-theory account against familiar objections. I conclude by arguing that the scientific-theory-theory account must be supplemented by an account of hypothesis discovery.

In this article I will evaluate the popular view that we acquire most of our concepts by means of learning. I will do this through an examination of Jerry Fodor’s dissenting views and those of some of his most persistent and significant critics. Although I will be critical of Fodor’s central claim that it is impossible to learn a concept, I will ultimately conclude that we should be more sceptical than is normal about the power of learning when it (...) comes to concept acquisition, particularly with respect to natural kind concepts. Central to my argument for this conclusion will be an examination of the bearings of psychological essentialism on concept acquisition. (shrink)

An explanation of how we acquire concepts of kinds if they are socially constructed is a desideratum both for a successful account of concept acquisition and a successful account of social constructionism. Both face the so-called “mismatch problem” that is based on the observation that that there is often a mismatch between the descriptions proficient speakers associate with a word and the properties that its referents have in common. I argue that externalist theories of reference provide a plausible (...) and attractive account of concept acquisition, including the acquisition of concepts of social constructs, that avoids the mismatch problem. However, externalist theories are ontologically and psychologically highly demanding, which places strong constraints on accounts of the metaphysics of socially constructed kinds. In particular, they require a rather strong form of realism that is incompatible with some but not all theories of social constructionism. Finally, I show that these demands can be met by means of adopting a homeostatic property cluster view of natural kinds. (shrink)

First I should clarify my thesis. When I say the mind starts off as a blank slate, I’m saying that it’s devoid of substantive concepts or ideas, that is non-logical concepts or ideas. Some examples of substantive concepts are: the concept of a cat, the concept of a quark, the concept of being square, and the concept of heaviness.

The alternative offered by Professor Stemmer to cognitivist theories of the process whereby general terms acquire their meaning is criticised in its turn on the grounds that it presents an oversimplified view of the complex processes involved in the acquisition of word meanings.

A realist story of concepts like Millikan's can and should accommodate facts about how the context of items available for comparison during concept formation affects just what concept is formed or reidentified. Similarly, the contribution of the goals and purposes of the conceptualizer are relevant to how concepts are acquired and deployed, but can be understood as entirely consistent with a view of concepts as objectively evaluable.

This article takes as its starting-point that a viable account of concept acquisition must be ontogenetically sound, and analyses in detail two alternative accounts of concept acquisition, one conceptualist and the other non-conceptualist, concluding that the conceptualist account is to be preferred.

In LOT 2: The Language of Thought Revisited, Jerry Fodor argues that concept learning of any kind—even for complex concepts—is simply impossible. In order to avoid the conclusion that all concepts, primitive and complex, are innate, he argues that concept acquisition depends on purely noncognitive biological processes. In this paper, we show (1) that Fodor fails to establish that concept learning is impossible, (2) that his own biological account of concept acquisition is unworkable, and (...) (3) that there are in fact many promising general models for explaining how concepts are learned. (shrink)

The objective of this paper is to discuss the nature of nonconceptual, as opposed to conceptual, states and their content, by exploring the suggestion that the distinction between the conceptual and the nonconceptual be mapped onto the distinction between the linguistic and the nonlinguistic. This approach gives special relevance to our intuitions about the cognitive relationship between small children and adults, especially regarding the acquisition of concepts, in the course of normal cognitive development. Assuming that there is a developmental (...) challenge to be met, the paper considers both the conceptualist and nonconceptualist strategies used to meet it; and concludes that conceptualism is a more satisfying option.

This volume features work on learning by researchers in various disciplines who share an interest in the systematic study of cognition and in the study of the formal and semantic aspects of language acquisition. A recurring theme is that language learning involves the acquisition of certain competencies and the formation of a system of beliefs which are significantly underdetermined by the linguistic and nonlinguistic inputs available to the learner. Theories of language learning must confront the epistemological problem of (...) how it is possible to induce and fixate a belief-system on the basis of exposure to limited data. A typical strategy in dealing with this problem has been to specify various types of formal and empirical constraints on linguistic and conceptual development in terms of specific hypotheses about the character of what is learned and about the kinds of resources and strategies available to the learner. Most of the contributions in this volume are concerned with the specification and evaluation of such constraints. (shrink)

Themistius's (ca. 317–ca. 388 C.E.) paraphrase of the De Anima is an influential and important work; however, it is not now regarded as profound or original and thereby suffers from neglect. I argue that Themistius is misunderstood on the matter of Aristotle's productive and potential intellects. It is commonly held that Themistius gives to the productive intellect the role of illuminating images in order to produce universal thoughts in the potential intellect with epistemic certainty. I argue that Themistius's productive intellect (...) does not transform images to reveal the forms contained therein, but gives to the potential intellect the ability, first, to organize our sense-experiences in the course of acquiring rudimentary universal concepts and, then, to discover the forms of things by ordinary discursive thinking.

Previous neural network models of concept learning were mainly implemented with supervised learning schemes. However, studies of human conceptual memory have shown that concepts may be learned without a teacher who provides the category name to associate with exemplars. A modular neural network architecture that realizes concept acquisition through two functionally distinct operations, categorizing and naming, is proposed as an alternative. An unsupervised algorithm realizes the categorizing module by constructing representations of categories compatible with prototype theory. The (...) naming module associates category names to the output of the categorizing module in a supervised mode. In such a modular architecture, the interface between the modules can be conceived of as an “information relay” that encodes, constrains, and propagates important information. Five experiments were conducted to analyze the relationships among internal conceptual codes and simple conceptual and lexical development. The first two experiments show a prototype effect and illustrate some basic characteristics of the system. The third experiment presents a bottom‐up model of the narrowing down of children's early lexical categories that honors mutual exclusivity. The fourth experiment introduces top‐down constraints on conceptual coding. The fifth experiment exhibits how hierarchical relationships between concepts are learned by the architecture, and also demonstrates how a spectrum of conceptual expertise may gradually emerge as a consequence of experiencing more with certain categories than with others.

Jerry Fodor has argued that concept acquisition cannot be a psychological or “rational-causal” process, but can only be a “brute-causal” process of acquisition. This position generates the “doorknob  DOORKNOB” problem: why are concepts typically acquired on the basis of experience with items in their extensions? I argue that Fodor’s taxonomy of causal processes needs supplementation, and characterize a third type: what I call “intelligible-causal processes.” Armed with this new category I present what I regard as a (...) better response than Fodor’s to the doorknob  DOORKNOB problem.

This paper examines the response offered by Robert Gordon to the question how an interpreter can reach the correct content of others'psychological states. It exposes the main problems raised by Gordon's proposal, and provides a tentative solution that emphasizes the structuring role of counterfactual reasoning in embedding simulations and deriving facts that are holding across them.

The acquisition of concepts has proven especially difficult for philosophers and psychologists to explain. In this paper, I examine Jerry Fodor’s most recent attempt to explain the acquisition of concepts relative to experiences of their referents. In reevaluating his earlier position, Fodor attempts to co-opt informational semantics into an account of concept acquisition that avoids the radical nativism of his earlier views. I argue that Fodor’s attempts ultimately fail to be persuasive. He must either accept his (...) earlier nativism or adopt a rational causal model of concept acquisition. His animus towards the latter dictates, in my view, a return to the nativism with which he began. (shrink)

It is often maintained that one insight of Kant's Critical philosophy is its recognition of the need to distinguish accounts of knowledge acquisition from knowledge justification. In particular, it is claimed that Kant held that the detailing of a concept's acquisition conditions is insufficient to determine its legitimacy. I argue that this is not the case at least with regard to geometrical concepts. Considered in the light of his pre-Critical writings on the mathematical method, construction in the (...) Critique can be seen to be a form of concept acquisition, one that is related to the modal phenomenology of geometrical judgement. (shrink)

Why Theories of Concepts Should Not Ignore the Problem of Acquisition.

This thesis aims to develop a psychologically plausible account of concepts by integrating key insights from philosophy (on the metaphysical basis for concept possession) and psychology (on the mechanisms underlying concept acquisition). I adopt an approach known as informational atomism, developed by Jerry Fodor. Informational atomism is the conjunction of two theses: (i) informational semantics, according to which conceptual content is constituted exhaustively by nomological mind–world relations; and (ii) conceptual atomism, according to which (lexical) concepts have no (...) internal structure. I argue that informational semantics needs to be supplemented by allowing content-constitutive rules of inference (“meaning postulates”). This is because the content of one important class of concepts, the logical terms, is not plausibly informational. And since, it is argued, no principled distinction can be drawn between logical concepts and the rest, the problem that this raises is a general one. An immediate difficulty is that Quine’s classic arguments against the analytic/synthetic distinction suggest that there can be no principled basis for distinguishing content-constitutive rules from the rest. I show that this concern can be overcome by taking a psychological approach: there is a fact of the matter as to whether or not a particular inference is governed by a mentally-represented inference rule, albeit one that analytic philosophy does not have the resources to determine. I then consider the implications of this approach for concept acquisition. One mechanism underlying concept acquisition is the development of perceptual detectors for the objects that we encounter. I investigate how this might work, by drawing on recent ideas in ethology on ‘learning instincts’, and recent insights into the neurological basis for perceptual learning. What emerges is a view of concept acquisition as involving a complex interplay between innate constraints and environmental input. This supports Fodor’s recent move away from radical concept nativism: concept acquisition requires innate mechanisms, but does not require that concepts themselves be innate. (shrink)

An enduring puzzle in philosophy and developmental psychology is how young children acquire number concepts, in particular the concept of natural number. Most solutions to this problem conceptualize young learners as lone mathematicians who individually reconstruct the successor function and other sophisticated mathematical ideas. In this chapter, I argue for a crucial role of testimony in children’s acquisition of number concepts, both in the transfer of propositional knowledge (e.g., the cardinality concept), and in knowledge-how (e.g., the counting (...) routine).

In the Introduction to the Critique of the Power of Judgment, Kant claims that the Critique of Pure Reason accounted for the necessary conditions of experience and knowledge in general, but that it was not a complete transcendental account of the possibility of a particular empirical experience of objects and knowledge of empirical laws of nature. To fill this gap the third Critique puts forward, as an additional transcendental condition, the regulative principle of the purposiveness of nature. In this paper, (...) I will attempt to show how Kant’s account of pure aesthetic judgment can be read as articulating an aesthetic non-conceptual condition of the search for the conceptual order of nature and so as constituting an essential part of the account of the transcendental conditions of empirical experience and knowledge.

Theories of number concepts often suppose that the natural numbers are acquired as children learn to count and as they draw an induction based on their interpretation of the first few count words. In a bold critique of this general approach, Rips, Asmuth, Bloomfield [Rips, L., Asmuth, J. & Bloomfield, A.. Giving the boot to the bootstrap: How not to learn the natural numbers. Cognition, 101, B51–B60.] argue that such an inductive inference is consistent with a representational system that clearly (...) does not express the natural numbers and that possession of the natural numbers requires further principles that make the inductive inference superfluous. We argue that their critique is unsuccessful. Provided that children have access to a suitable initial system of representation, the sort of inductive inference that Rips et al. call into question can in fact facilitate the acquisition of larger integer concepts without the addition of any further principles.
