According to factive accounts of the norm of belief and decision-making, you should not believe or base decisions on a falsehood. Even when the evidence misleadingly suggests that a false proposition is true, you should not believe it or base decisions on it. Critics claim that factive accounts are counterintuitive and badly mischaracterize our ordinary practice of evaluating beliefs and decisions. This paper reports four experiments that rigorously test the critic’s accusations and the viability of factive accounts. The results undermine (...) the accusations and provide the best evidence yet of factive norms of belief and decision-making. The results also help discriminate between two leading candidates for a factive norm: truth and knowledge. Knowledge is the superior candidate. (shrink)

Assertion is fundamental to our lives as social and cognitive beings. Philosophers have recently built an impressive case that the norm of assertion is factive. That is, you should make an assertion only if it is true. Thus far the case for a factive norm of assertion been based on observational data. This paper adds experimental evidence in favor of a factive norm from six studies. In these studies, an assertion’s truth value dramatically affects whether people think it should be (...) made. Whereas nearly everyone agreed that a true assertion supported by good evidence should be made, most people judged that a false assertion supported by good evidence should not be made. The studies also suggest that people are consciously aware of criteria that guide their evaluation of assertions. Evidence is also presented that some intuitive support for a non-factive norm of assertion comes from a surprising tendency people have to misdescribe cases of blameless rule-breaking as cases where no rule is broken.

The past eighteen years witnessed the rapid development of experimental philosophy of language. Adopting a bibliometric approach, this study examines the research trends and status quo of this burgeoning field based on a corpus of 237 publications retrieved from PhilPapers. It is observed that experimental philosophy of language has undergone three stages, the initiation stage, the development stage, and the extension stage, across which there is a clear upward trend in the annual number of publications. Michael Devitt, Edouard Machery, John (...) Turri, Nat Hansen, et al., are found to be the most productive philosophers, testifying their leading positions in this field. Journals, instead of books, are the major homes of works in this area. The analysis also yields a list of influential works, including the seminal work “Semantics, Cross-cultural Style” and other significant publications on the semantics of various types of expressions. Relatedly, the major research themes are found to include not only intuitions about the reference of proper names, but also a wide array of philosophically and linguistically interesting issues like the meaning of color adjectives, epistemic modals, and predicates of personal taste, the norms of assertions and the essence of lies, etc. These findings showcase that experimental philosophy of language has broadened the research territory and offered deep insights into central issues of philosophy of language that are beyond the reach of the conventional armchair methodology.

Complex human reasoning involves minimal abilities to extract conclusions implied in the available information. These abilities are considered “deductive” because they exemplify certain abstract relations among propositions or probabilities called deductive arguments. However, the electrophysiological dynamics which supports such complex cognitive pro- cesses has not been addressed yet. In this work we consider typically deductive logico- probabilistically valid inferences and aim to verify or refute their electrophysiological functional connectivity differences from invalid inferences with the same content (same relational variables, same (...) stimuli, same relevant and salient features). We recorded the brain electrophysiological activity of 20 participants (age 1⁄4 20.35 ± 3.23) by means of an MEG system during two consecutive reasoning tasks: a search task (invalid condition) without any specific deductive rules to follow, and a logically valid deductive task (valid condition) with explicit deductive rules as instructions. We calculated the functional connectivity (FC) for each condition and conducted a seed-based analysis in a set of cortical regions of interest. Finally, we used a cluster-based permutation test to compare the dif- ferences between logically valid and invalid conditions in terms of FC. As a first novel result we found higher FC for valid condition in beta band between regions of interest and left prefrontal, temporal, parietal, and cingulate structures. FC analysis allows a second novel result which is the definition of a propositional network with operculo-cingular, parietal and medial nodes, specifically including disputed medial deductive “core” areas. The experiment discloses measurable cortical processes which do not depend on content but on truth-functional propositional operators. These experimental novelties may contribute to understand the cortical bases of deductive processes. (shrink)

Most contemporary accounts of the nature of faith explicitly defend what we call ‘the positivity theory of faith’ – the theory that faith must be accompanied by a favourable evaluative belief, or a desire towards the object of faith. This paper examines the different varieties of the positivity theory and the arguments used to support it. Whilst initially plausible, we find that the theory faces numerous problematic counterexamples, and show that weaker versions of the positivity theory are ultimately implausible. We (...) discuss a distinct property of faith that we call ‘true grit’, such that faith requires one to be resilient toward the evidential, practical, and psychological challenges that it faces. We show how true grit is necessary for faith, and provides a simpler and less problematic explanation of the evidence used to support the positivity theory. (shrink)

An impressive case has been built for the hypothesis that knowledge is the norm of assertion, otherwise known as the knowledge account of assertion. According to the knowledge account, you should assert something only if you know that it’s true. A wealth of observational data supports the knowledge account, and some recent empirical results lend further, indirect support. But the knowledge account has not yet been tested directly. This paper fills that gap by reporting the results of such a test. (...) The knowledge account passes with flying colors. (shrink)

One of the most experimentally studied scales in the literature on scalar implicatures is the quantifier scale. While the truth of some is entailed by the truth of all, some is felicitous only when all is false. This opens the possibility that some would be felicitous if, e.g., 99% of the objects in the domain of quantification fall under it, a conclusion that clashes with native speakers’ intuitions. In Experiment 1 we report a questionnaire study on the perception of quantifier (...) meanings in English, French, Slovenian and German which points to a cross-linguistic variation with respect to the perception of numerical bounds of the existential quantifier. In Experiment 2, using a picture choice task, we further examine whether the numerical bound differences correlate with differences in pragmatic interpretations of the quantifier some in English and quelques in French and interpret the results as supporting our hypothesis that some and its cross-linguistic counterparts are subjected to different processes of pragmatic enrichment.

The distinction between literal and figurative use is well-known and embedded in ‘folk linguistics’. According to folk linguistics, figurative uses deviate from literal ones. But recent work on lexical modulation and polysemy shows that meaning deviation is ubiquitous, even in cases of literal use. Hence, it has been argued, the literal/figurative distinction has no value for theorising about communication. In this paper, we focus on metaphor and argue that here the literal–figurative distinction has theoretical importance. The distinction between literal and (...) metaphorical needs to be captured by our account of communication because literal uses transmit information in a way that metaphorical ones do not. We argue that there is a way to explain the literal/metaphorical distinction that preserves the core of the folk-linguistic idea and gives the distinction theoretical relevance. We propose that literal uses of a word are made with the intention to conform to an established practice of use, while metaphorical uses do not so conform, but depend on this pre-existing practice. Our account can deal with data that are problematic for other theories. A further advantage is that it extends naturally to other non-literal uses of words, including metonymy. (shrink)

Whether truth is absolute or relative has been a widely discussed topic for over two thousand years in epistemology and the philosophy of science. However, this issue has not yet been discussed systematically with respect to linguistics. The present paper attempts to make the first step toward filling this gap. It raises the following question in Sect. 1: What kind of relationship is there between the pluralism of inquiry, the relativistic and the absolutistic approach to truth, and the tolerance of (...) views differing from one’s own in the practice of linguistic research? After Sect. 2 has clarified what is meant by ‘relativism’, ‘absolutism’, ‘pluralism’ and ‘tolerance’, Sects. 3–5 describe, analyse, and systematize the ways in which relativistic and absolutistic views are manifested in linguistic theorizing. Finally, Sect. 6 summarizes the findings and gives a sophisticated answer to the main question of the paper. (shrink)
