Tarski’s conceptual analysis of the notion of logical consequence is one of the pinnacles of the process of defining the metamathematical foundations of mathematics in the tradition of his predecessors Euclid, Frege, Russell and Hilbert, and his contemporaries Carnap, Gödel, Gentzen and Turing. However, he also notes that in defining the concept of consequence “efforts were made to adhere to the common usage of the language of every day life.” This paper addresses the issue of what relationship Tarski’s analysis, and (...) Béziau’s further generalization of it in universal logic, have to reasoning in the everyday lives of ordinary people from the cognitive processes of children through to those of specialists in the empirical and deductive sciences. It surveys a selection of relevant research in a range of disciplines providing theoretical and empirical studies of human reasoning, discusses the value of adopting a universal logic perspective, answers the questions posed in the call for this special issue, and suggests some specific research challenges.

This paper explores a variety of different versions of the thesis that natural language is involved in human thinking. It distinguishes amongst strong and weak forms of this thesis, dismissing some as implausibly strong and others as uninterestingly weak. Strong forms dismissed include the view that language is conceptually necessary for thought (endorsed by many philosophers) and the view that language is _de facto_ the medium of all human conceptual thinking (endorsed by many philosophers and social scientists). Weak forms include (...) the view that language is necessary for the acquisition of many human concepts, and the view that language can serve to scaffold human thought processes. The paper also discusses the thesis that language may be the medium of _conscious_ propositional thinking, but argues that this cannot be its most fundamental cognitive role. The idea is then proposed that natural language is the medium for non-domain-specific thinking, serving to integrate the outputs of a variety of domain-specific conceptual faculties (or central-cognitive ‘quasi-modules’). Recent experimental evidence in support of this idea is reviewed, and the implications of the idea are discussed, especially for our conception of the architecture of human cognition. Finally, some further kinds of evidence which might serve to corroborate or refute the hypothesis are mentioned. The overall goal of the paper is to review a wide variety of accounts of the cognitive function of natural language, integrating a number of different kinds of evidence and theoretical consideration in order to propose and elaborate the most plausible candidate.

According to the weak version of linguistic relativity, also called the Sapir-Whorf hypothesis, the features of an individual’s native language influence his worldview and perception. We decided to test this hypothesis on the sufficient conditional and the necessary conditional, expressed differently in Chinese and French. In Chinese, connectors for both conditionals exist and are used in everyday life, while there is only a connector for the sufficient conditional in French. A first hypothesis follows from linguistic relativity: for the necessary conditional, (...) better logic performance is expected in Chinese participants rather than French participants. As a second hypothesis, for all participants, we expect performance on the sufficient conditional to be better than on the necessary conditional. Indeed, despite the isomorphism of the two conditionals, they differ in how information is processed for reasoning. We decided to study reasoning under uncertainty as it reflects reality more accurately. To do so, we analyzed the coherence of participants using de Finetti’s theory for deduction under uncertainty. The results of our study show no significant difference in performance between Chinese and French participants, neither on the sufficient conditional nor on the necessary conditional. Thus, our first hypothesis derived from the weak version of linguistic relativity is not confirmed. In contrast, our results confirm the second hypothesis in two out of three inference schemas.

To talk about time, English speakers often use horizontal spatial metaphors whereas Chinese speakers use both vertical and horizontal spatial metaphors. Boroditsky showed that while Chinese-English bilinguals were faster to verify a temporal target like June comes earlier than August after they had seen a vertical spatial prime rather than a horizontal spatial prime, English monolinguals showed the reverse pattern, thus supporting the linguistic relativity hypothesis. This finding was not conceptually replicated in January and Kako's six experiments for English monolinguals. (...) In the current experiment, we failed to conceptually replicate her English monolinguals' findings: both Chinese-English bilinguals and English monolinguals were faster to verify the sentences after seeing a vertical spatial prime than a horizontal spatial prime. While we replicated Boroditsky's findings, in part, for our Chinese-English bilinguals, the similarity in the pattern of findings for both Chinese-English bilinguals and English monolinguals argues against the linguistic relativity hypothesis.

"Rationality: Contexts and Constraints" is an interdisciplinary reappraisal of the nature of rationality. In method, it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between traditional scholarship and cutting-edge philosophical or scientific research. In this way, the book contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, (...) and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. Addresses recent challenges and Identifies a direction for future research on rationalityInvestigates the relationship between rationality and mental disorders, such as delusion and depressionAssesses reasoning in artificial intelligence and nonhuman animalsReflects on ancient Chinese Philosophy and possible cultural differences in human psychology Employs philosophical reflection, along with linguistic, probabilistic, and logical techniques.

What would it be like to have never learned English, but instead only to know Hopi, Mandarin Chinese, or American Sign Language? Would that change the way you think? Imagine entirely losing your language, as the result of stroke or trauma. You are aphasic, unable to speak or listen, read or write. What would your thoughts now be like? As the most extreme case, imagine having been raised without any language at all, as a wild child. What—if anything—would it be (...) like to be such a person? Could you be smart; could you reminisce about the past, plan the future? (shrink)

A counterpossible is a counterfactual whose antecedent is impossible. The vacuity thesis says all counterpossibles are true solely because their antecedents are impossible. Recently, some have rejected the vacuity thesis by citing purported non-vacuous counterpossibles in science. One limitation of this work, however, is that it is not grounded in experimental data. Do scientists actually reason non-vacuously about counterpossibles? If so, what is their basis for doing so? We presented biologists (N = 86) with two counterfactual formulations of a well-known (...) model in biology, the antecedents of which contain what many philosophers would characterize as a metaphysical impossibility. Participants consistently judged one counterfactual to be true, the other to be false, and they explained that they formed these judgments based on what they perceived to be the mathematical relationship between the antecedent and consequent. Moreover, we found no relationship between participants’ judgments about the (im)possibility of the antecedent and whether they judged a counterfactual to be true or false. These are the first experimental results on counterpossibles in science with which we are familiar. We present a modal semantics that can capture these judgments, and we deal with a host of potential objections that a defender of the vacuity thesis might make. (shrink)

This article seeks to synthesise three fields of inquiry – management studies, linguistics and cognitive psychology – to explore an arguably emerging phenomenon of global management knowledge impoverishment. To this end, three literatures are reviewed and interrogated for the insights they may provide into the underlying factors affecting global MK: trends in knowledge production, Englishisation of management scholarship and the culturally determined differences in cognition. Arguments are developed through descriptive investigation, discussion and analysis. The central proposition of this article is (...) that the politics of knowledge production, the hegemony of English as the dominant language of management studies and the variations in thinking styles are synergistically interlinked in a way that facilitates Anglophone homogenisation of management research and potentially leads to global MK impoverishment. The ways of addressing the situation are discussed. (shrink)

Here we develop a view of language as a form of material engagement, one that foregrounds its embodied and ecological character. Achieving such a view, however, requires disabusing ourselves of certain received and deeply entrenched notions. We present a thought experiment meant to illuminate the materiality of language, as a technological activity on par with the construction and manipulation of artifacts. We explore its implications, justifying the comparison with actual languages while emphasizing revealing differences. Ultimately, we hope to expose the (...) embodied and enactive nature of language, offering a view of language as continuous with our engagement with the environment, as opposed to a picture of language as an essentially symbolic system or code.

Grounded in the use of the visual, Chinese thought and language operate within a wide spectrum that includes calligraphy, poetry, literature, painting, and garden-landscapes. In languages of phonetic signifiers, the spectrum is deliberately controlled to be narrower, excluding the visual from language and delegating it to iconology. These linguistic-cultural strategies have an ancient past and produce far-reaching consequences in thought and artefacts, with garden-landscapes being one of the most substantial outcomes. Garden-landscapes are China’s equivalent to Greek architecture, leading us to (...) both a repositioning of Chinese thought and a new framework of architecture. In this sense, the city, serving the function of thought in the expanded medium of conceptual and material units of meanings (figures), incorporates things into intellectual orders. This is perhaps the most important feature of Chinese thought and one that is the first to be obscured when it is rendered in scholarship in Indo-European languages. (shrink)

This paper is an investigation of the degree of incommensurability between Western scientific medicine and traditional Chinese medicine, focusing on the practice and theory of acupuncture. We describe the structure of traditional Chinese medicine, oriented around such concepts as yin, yang, qi, and xing, and discuss how the conceptual and explanatory differences between Western medicine and traditional Chinese medicine generate impediments to their comparison and evaluation. We argue that the linguistic, conceptual, ontological, and explanatory impediments can to a large extent (...) be overcome, and conclude that the dramatic differences between Western and traditional Chinese medicine do not provide insurmountable barriers to rational evaluation of acupuncture. We conclude with a discussion of the intentional and emotional aspects of conceptual change. (shrink)

The claim that Chinese had neither unambiguous, nor obligatory syntactic or morphological markers of counterfactuality, which has loomed large with philosophers of language, sinologists, and cognitive psychologists during the better part of the 20th century, is reviewed here from a diachronic and typological perspective, focussing on Old Chinese. In contradistinction from the cross-linguistically widespread use of past-tense morphology or, less commonly, of dissociative spatial markers, the predominant strategy to mark counterfactuals in OC was ‘direct’ assertion in the protasis. It made (...) use of a non-indicative copula marked for stativity by prefixation, which acts as a complementizer vis-à-vis the dependent clause. Morphological analysis, building upon advances in the reconstruction of OC phonology in Jacques, suggests that OC combined this non-indicative copula with a causative morpheme to encode concessives and with an existential negative to express a non-facultative negative counterfactual, surfacing as wēi 微. Straightforward “positive” counterfactuality could also be expressed through conjunction compounding in late Classical and Medieval Chinese, or by the use of simple superordinate verbs such as shǐ 使 or lìng 令. Morphologically, these share the property of being derived from the underlying verb base by causative or deontic prefixes, but CF interpretation also depends on the interplay with schetic markers and pragmatic embedding in the remainder of the sentence. Non-obligatory marking of counterfactuals thus emerges as a preference, not as a categorical incapacity, while the choice of ‘direct’ assertion, rather than temporal or distal implicatures to convey it, is unrelated to the richness of morphology in a given language.

Sociolinguistics is a young and vigorous branch of linguistics. Brought to life in the late 1960s through the pioneering work on urban dialects by William Labov and his students, it developed rapidly. From the end of the 1970s, it expanded to include a vast range of studies focusing on various relations between language and society. From sociolinguistics in the narrow sense—the study of correlations between linguistic and nonlinguistic variables—it came to be used as an umbrella term of loosely connected research (...) into the interdependence and mutual influence of language and social life. Nowadays, sociolinguistics is an interdisciplinary field, focusing on such issues as social dialects, multilingualism, language planning, and language reform and change. (shrink)
