A hipótese do fechamento cognitivo afirma que, devido à organização cognitiva da mente humana, a classe de conceitos acessíveis é limitada e que por consequência deste fato algumas crenças e hipóteses sobre aspectos da realidade terão de estar fora do alcance teórico humano e serão inacessíveis. Neste artigo, analisamos uma interpretação de David Hume, segundo a qual o autor afirmou conjuntamente a tese realista de que poderes causais em objetos existem e a tese cética de que não temos um acesso (...) à natureza destes poderes, sensório ou conceitual. Para tal, contextualizamos o surgimento desta interpretação como uma alternativa aos fracassos da interpretação tradicional de Hume e analisamos individualmente as abordagens realizadas por seus principais defensores. Assim feito, buscamos explorar à luz desta interpretação realista cética a possibilidade da tese de Hume ter antecipado a tese contemporânea do fechamento cognitivo. Acredita-se que essa hipótese implica um desafio tanto a interpretações que enxergam o filósofo como um precedente da filosofia analítica do positivismo lógico quanto a acusações de que fechamento cognitivo é uma tese pós-moderna.

Traditional arguments against the identification of the language of thought with natural language assume a picture of natural language which is largely inconsistent with that suggested by contemporary linguistic theory. This has led certain philosophers and linguists to suggest that this identification is not as implausible as it once seemed. In this paper, I discuss the prospects for such an identification in light of these developments in linguistic theory. I raise a new challenge against the identification thesis: the existence of (...) ungrammatical but acceptable expressions seems to require a gap between thought and language. I consider what must be the case in order for this objection to be dealt with. (shrink)

One of the constants in Noam Chomsky’s philosophical, linguistic and ethical positions is the existence of what he calls “human nature”. Following Marx, Darwin and last century’s revolutions in the social sciences, human nature has been one of the most contested conceptual holdovers from modern European philosophy. Chomsky’s discoveries and models on syntax and language make up one of the frameworks to most critically offset the traditional moral dimension of human nature. Contrary to most traditions prior to his work, language (...) can no longer be restricted to either mind, soul or spirit. Language, as Chomsky has continually upheld and sharply refined, is a physical and biological process. But how his notion of human nature derives from this process is complex, as he seems to disregard philosophy’s classic analytic delineation between the descriptive causal realm of human nature and the normative axiological extensions of the same concept. In this paper, we seek to examine the philosophical and ontological implications of Chomsky’s claim that human nature derives from the innate dimension of the language faculty. Not only does Chomsky maintain the category of human nature, he also indexes it to the question of freedom. We thereby argue for the coherence of his proposal and show how it operates to weld the perspective of a modal theory of biologically-rooted creativity to innate conditions specific to his theory of language generation. However, we question whether its restriction to humans alone is sustainable from a scientific perspective by putting forth the claim that Chomsky’s science is in fact a radical ontology of social subjectivation.

This article reviews and attempts to evaluate the various proposals for a strong minimalist thesis that have been at the core of the minimalist program for linguistic theory since its inception almost three decades ago. These proposals have involved legibility conditions for the interface between language and the cognitive systems that access it, the simplest computational operation Merge (its form and function), and principles of computational efficiency (including inclusiveness, no-tampering, cyclic computation, and the deletion of copies). This evaluation attempts to (...) demonstrate that reliance on interface conditions encounters serious long-standing problems for the analysis of language. It also suggests that the precise formulation of Merge may, in fact, subsume the effects of those principles of efficient computation currently under investigation and might possibly render unnecessary proposals for additional structure building operations (e.g., Pair-Merge and FormSequence).

Generative grammarians typically advocate for a rationalist understanding of language acquisition, according to which the structure of a developed language faculty reflects innate guidance rather than environmental influence. This proposal is developed in developmental linguistics by triggering models of language acquisition. Opposing this tradition, various theorists have advocated for empiricist views of language acquisition, according to which the structure of a developed linguistic competence reflects the linguistic environment in which this competence developed. On this picture, linguistic development is accounted for (...) by general statistical learning mechanisms. In this article I shall precisify the debate, provide a clearer picture of what is at stake, and show why an intermediate picture is needed. (shrink)

In this commentary on Berwick and Chomsky's “Why Only Us,” I discuss three key points. I first offer a brief critique of their scholarship, notably their often unjustified dismissal of previous thinking about language evolution. But my main focus concerns two arguments central to the book's thesis: the irrelevance of externalization to language evolution and the discontinuity between human conceptual representations and those of other animals. I argue against both stances, using cognitive data from nonhuman species to show that externalization (...) is not irrelevant to understanding the biology of language, and that many human conceptual structures have clear animal homologs.

Free will is a very hot issue in several theoretical settings, but less in theology, or at least not as much as use to be in former times, when the discussions on sinfulness, grace and freedom were igniting a long season of controversies, especially in the Reformation time. Even in ecumenical dialogue apparently free will does not play a great role, since the reached consensus seems quite peaceful and agreement dominates over discussion. However, some theological insights, especially Karl Rahner reflections, (...) are still worthy to consider and possibly theological anthropology should pay more attention to the current debate and its consequences for the way we understand human nature and its relationship with God.
