Vigorous Fodorian criticism may make it seem impossible for Inferential Role Semantics to accommodate compositionality. In this paper, first, I introduce a neo-Fregean version of IRS that appeals centrally to the notion of rationality. Second, I show how such a theory can respect compositionality by means of semantic rules. Third, I argue that, even if we consider top-down compositional derivability: a) the Fodorian is not justified in claiming that it involves so-called reverse compositionality; and b) a defender of IRS can (...) still offer a satisfactory account in terms of the inferential capacities of rational thinkers.

The theory of concepts advanced in the present discussion aims at accounting for a) how a concept makes successful practice possible, and b) how a scientific concept can be subject to rational change in the course of history. To this end, I suggest that each scientific concept consists of three components of content: 1) the concept.

La tesis aborda uno de los temas centrales en la filosofía de la mente y las ciencias cognitivas: los conceptos como unidades básicas de la cognición humana. La tesis central que se defiende es que el contenido de los conceptos es determinado parcialmente por las comunidades a las que pertenecen los sujetos cognitivos, en la medida en la que dichas comunidades guían y constriñen las interacciones entre el sistema cognitivo conceptual y el entorno del que forma conceptos. La novedad de (...) la tesis es doble. Por una parte, cuestiona las teorías dominantes sobre el contenido de los conceptos —las teorías descriptivistas y las teorías naturalistas—, no solamente a partir de desafíos filosóficos que muestran sus limitaciones, sino también a partir de evidencia empírica sobre el efecto de las interacciones sociales en el contenido de los conceptos y, por tanto, en la cognición. Por otra parte, proporciona evidencia empírica sobre infantes ferales (i.e. niños salvajes), cuyo sistema cognitivo conceptual no ha recibido la guía de ninguna comunidad humana en sus interacciones con el entorno. Dicha evidencia permite sugerir que una explicación puramente naturalizada del contenido, sin la presencia de las comunidades, no puede explicar el desarrollo cognitivo conceptual de dichos infantes. Así, la tesis logra proponer un papel no trivial de las comunidades en el debate sobre la determinación del contenido semántico de los conceptos. (shrink)

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)

The theory of concepts advanced in the dissertation aims at accounting for a) how a concept makes successful practice possible, and b) how a scientific concept can be subject to rational change in the course of history. Traditional accounts in the philosophy of science have usually studied concepts in terms only of their reference; their concern is to establish a stability of reference in order to address the incommensurability problem. My discussion, in contrast, suggests that each scientific concept consists of (...) three components of content: 1) reference, 2) inferential role, and 3) the epistemic goal pursued with the concept's use. I argue that in the course of history a concept can change in any of these three components, and that change in one component—including change of reference—can be accounted for as being rational relative to other components, in particular a concept's epistemic goal.This semantic framework is applied to two cases from the history of biology: the homology concept as used in 19th and 20th century biology, and the gene concept as used in different parts of the 20th century. The homology case study argues that the advent of Darwinian evolutionary theory, despite introducing a new definition of homology, did not bring about a new homology concept (distinct from the pre-Darwinian concept) in the 19th century. Nowadays, however, distinct homology concepts are used in systematics/evolutionary biology, in evolutionary developmental biology, and in molecular biology. The emergence of these different homology concepts is explained as occurring in a rational fashion. The gene case study argues that conceptual progress occurred with the transition from the classical to the molecular gene concept, despite a change in reference. In the last two decades, change occurred internal to the molecular gene concept, so that nowadays this concept's usage and reference varies from context to context. I argue that this situation emerged rationally and that the current variation in usage and reference is conducive to biological practice.The dissertation uses ideas and methodological tools from the philosophy of mind and language, the philosophy of science, the history of science, and the psychology of concepts.

Od radykalnego przekładu do radykalnej interpretacji – Quine, Davidson i coś jeszcze Ponad trzydzieści lat począwszy od roku 1970 filozofia Willarda Van Ormana Quine'a i Donalda Davidsona stanowiła dominujący nurt w teorii interpretacji, epistemologii i ontologii. Rekonstruując i analizując tę tradycję w pierwszym kroku zarysowuję zwrot Quine'a od teorii znaczenia ku teorii przekładu. Jest to jednocześnie zwrot w stronę naturalizacji epistemologii, post-empiryzmu w teorii znaczenia i radykalnego przekładu oraz jego teorii bazowej. Post-empiryzm w teorii znaczenia głosi, że przekonania i inne (...) postawy propozycjonalne są nierozerwalnie połączone ze znaczeniem. Epistemologia znaturalizowana twierdzi natomiast, że owo połączenie pęka, jeśli wprowadzi się koncepcję znaczenia jako bodźca. Jednak, jak będę argumentował kolejnym kroku, znaczenie jako bodziec nie wyjaśnia epistemicznych warunków radykalnego przekładu. Następnie, po analizie koncepcji radykalnego przekładu Quine'a przejdę do koncepcji radykalnej interpretacji Davidsona. Przeprowadzę analizę przebudowy modelu radyklanego przekładu na model radykalnej interpretacji, przy jednoczesnym odrzuceniu jego teorii bazowe. W koncepcji Davidsona szczególnie interesujące jest to, czy teoria znaczenia oparta na warunkach prawdziwości oraz zastosowanie zasady życzliwości jako warunków każdej interpretacji mogą załatać epistemiczną przepaść. Zostanie tu wykazane, że wypowiedzi nadawcy nie mogą być rozumiane przez zastosowanie zasady życzliwości jako ogólnego warunku radykalnej interpretacji. Na końcu swoich rozważań zaproponuję alternatywne ramy dla modelu radykalnej interpretacji. (shrink)

One of the current debates in philosophy of mind is whether the content of perceptual experiences is conceptual or nonconceptual. The proponents of nonconceptual content, or nonconceptualists, typically support their position by appealing to the so-called Fineness of Grain Argument, which, in rough terms, has as its conclusion that we do not possess concepts for everything we perceive. In his Mind and World, John McDowell tried to give a response to the argument, and show that we do possess concepts for (...) everything we perceive. His response is based on the idea that we have a capacity to recognize all that we perceive. However, a good number of people took this proposal as being empirically false. My aim in this paper is to show that McDowell’s proposal is not only not empirically false, but likely to be empirically true. We do have the capacity to recognize all that we perceive, but such recognition capacity is dependent on information stored in short-term memory, and not in longterm memory, as McDowell’s critics have mistakenly supposed.
