Everett (2005) has claimed that the grammar of Piraha˜ is exceptional in displaying ‘inexplicable gaps’, that these gaps follow from a cultural principle restricting communication to ‘immediate experience’, and that this principle has ‘severe’ consequences for work on universal grammar. We argue against each of these claims. Relying on the available documentation and descriptions of the language, especially the rich material in Everett 1986, 1987b, we argue that many of the exceptional grammatical ‘gaps’ supposedly characteristic of Piraha˜ are misanalyzed by (...) Everett (2005) and are neither gaps nor exceptional among the world’s languages. We find no evidence, for example, that Piraha˜ lacks embedded clauses, and in fact find strong syntactic and semantic evidence in favor of their existence in Piraha˜. Likewise, we find no evidence that Piraha˜ lacks quantifiers, as claimed by Everett (2005). Furthermore, most of the actual properties of the Piraha˜ constructions discussed by Everett (for example, the ban on prenominal possessor recursion and the behavior of WH-constructions) are familiar from languages whose speakers lack the cultural restrictions attributed to the Piraha˜. Finally, following mostly Gonc¸alves (1993, 2000, 2001), we also question some of the empirical claims about Piraha˜ culture advanced by Everett in primary support of the ‘immediate experience’ restriction. We conclude that there is no evidence from Piraha˜ for the particular causal relation between culture and grammatical structure suggested by Everett. (shrink)

Recent research has suggested that the Pirahã, an Amazonian tribe with a number-less language, are able to match quantities > 3 if the matching task does not require recall or spatial transposition. This finding contravenes previous work among the Pirahã. In this study, we re-tested the Pirahãs’ performance in the crucial one-to-one matching task utilized in the two previous studies on their numerical cognition, as well as in control tasks requiring recall and mental transposition. We also conducted a (...) novel quantity recognition task. Speakers were unable to consistently match quantities > 3, even when no recall or transposition was involved. We provide a plausible motivation for the disparate results previously obtained among the Pirahã. Our findings are consistent with the suggestion that the exact recognition of quantities > 3 requires number terminology. (shrink)

In order to present the incidence of the dynamic turn in the logic of scientific research, we begin with a section, in this article, that deals with logical games as triggers of this dynamic turn in contemporary logic, together with the program of logical dynamics of information and interaction. We briefly introduce the main characteristics of the logic favorable to independence and the game-theoretical semantics, of dialogical logic, as well as the essential elements of this program. Although from any of (...) these points of view we have a list of logical tools to deal with more clearly epistemological issues, we highlight the role of dynamic epistemic logic, to which we dedicate the following section. There follows another one in which we enter the logical studies of abduction as one of the fundamental problems of contemporary epistemology and, in a new section, in terms of the theoretical constructs of the preceding sections, we present and explain a phenomenon that emerged in the field of linguistics, the case of the discovery of the Amazonian language pirahã, which should be considered an anomaly within the framework of the Chomskian theory.

Building on Dor’s theory of language as a social technology for the instruction of imagination, I suggest that autobiographical memory evolved culturally as a response to the problems of false memory and deliberate deceit that were introduced by that technology. I propose that sapiens’ linguistic communication about past and future events initially occurred in small groups, and this helped to correct individual memory defects. However, when human groups grew in size and became more socially differentiated, and movement between groups prevented (...) story-verification, misattributions of events became more common. In such conditions individuals with better autobiographical memory had an advantage because they could evaluate their own contents and sources of information, as well as that of others, more accurately; this not only benefitted them directly, but also improved their reliability as social partners. Autobiographical memory thus evolved in the context of human linguistic communication through selection for communicative reliability. However, the advantages of imagination, which enables forward-planning and decision-Making, meant that memory distortions, although controlled and moderated by autobiographical memory, could not be totally eradicated. This may have driven the evolution of additional forms of memory control involving social and linguistic norms. I interpret the language and the social norms of the Pirahã as the outcome of the cultural-evolutionary control of memory distortions. Some ways of testing aspects of this proposal are outlined.

A cultural change occurred roughly 40,000 years ago. For the first time, there was evidence of belief in unseen agents and an afterlife. Before this time, humans did not show widespread evidence of being able to think about objects, persons, and other agents that they had not been in close contact with. I argue that one can explain this transition by appealing to a population increase resulting in greater exoteric (inter-group) communication. The increase in exoteric communication triggered the actualization of (...) a dormant potential for greater syntactic computational power; specifically it triggered syntactic movement. Syntactic movement, in turn, made possible variable binding, which crucially figures into cognition by description, a naturalistic analogue of Russell’s knowledge by description. Cognition by description made possible the ability to conceive of things one had never experienced, such as mythological beings, places only visited by the dead, and so forth. The Amazonian Pirahã provide some corroboration for this hypothesis, since they exhibit the combination of traits here attributed to Middle Paleolithic individuals, namely exclusively esoteric (intra-group) communication, evident lack of syntactic movement, and a limitation to knowledge (cognition) by acquaintance.

A simple inductive argument shows natural languages to have infinitly many sentences, but workers in the field have uncovered clear evidence of a diverse group of ‘exceptional’ languages from Proto-Uralic to Dyirbal and most recently, Pirahã, that appear to lack recursive devices entirely. We argue that in an information-theoretic setting non-recursive natural languages appear neither exceptional nor functionally inferior to the recursive majority.

The controversies surrounding Daniel Everett's characterization of the Amazonian language Pirahã and the Evans and Levinson paper about "the myth of language universals" (2009) are just two recent manifestations of a debate about linguistic theory and methodology that is anything but new.

“It is a noble task to try to understand others, and to have them understand you but it is never an easy one”, says Everett. This paper argues that a basic prerequisite for understanding others is to have some shared concepts on which this understanding can build. If speakers of different languages didn’t share some concepts to begin with then cross-cultural understanding would not be possible even with the best of will on all sides. Current Anthropology For example, Everett claims (...) that Pirahã has no word for “mother”, no words for “before’ and “after”, no words for “one”, “two” and “all” and no words comparable to ‘think” and “want”. These claims are based, I believe, on faulty semantic analysis, and in particular, on a determination not to recognize polysemy under any circumstances. As I see it, at many points this stance makes nonsense of Everett’s own data and distorts the conceptual world of the Pirahã. Since he does not want to recognize the existence of any shared concepts, Everett is also not prepared to address the question of a culture-neutral metalanguage in which Pirahã and English conceptual categories could be compared. This often leads him to imposing cultural categories of English on the conceptual world of the Pirahã. The result is a combination of exoticism and Anglocentrism which doesn’t do justice to Everett’s long and intimate engagement with the Pirahã people and their language. Sadly, it blinds him to what Franz Boas called “the psychic unity of mankind”, reflected in the common semantic features of human languages and fully compatible with the cultural shaping of their lexicons and grammars.

This book is an exploration of interrelationships among culture, language, and the individual unconscious (the "dark matter of the mind”), how these feed into a sense of self, and implications for the notion of "human nature.” The first part of the book is concerned with perceptual and cultural bases of dark matter and the effect of dark matter on perception (especially vision) and the interpretation of discourse. The second part is concerned with the contribution of dark matter to language--with language (...) viewed as a combination of speech and gesture, and including issues related to translation. In the final part Everett addresses implications of his account, summarizing and extending arguments for replacing an instinct-based account of human nature with a culturally-based, dark matter view of the "constructed self.” Everett makes a powerful argument for the influence of culture on unconscious forces that underlie human behavior and the individual’s sense of self, with much of the power of the argument coming from the deep insights he gained from living and working with the Pirahãs of the Amazon. This is an important book that sits at the intersection of anthropology, linguistics, psychology, and philosophy, and it is enriched by a combination of the author’s knowledge of these fields and his cross-cultural perspective. The book will make an important contribution to newly emerging directions taken by cognitive science. After decades of a field derailed by ethnocentric, instinct-based views of language and the mind, the cognitive sciences need such informed analyses of the relationship between culture, cognition, and language, as embodied in speech and gesture.
