Analytic debates about truth are wide-ranging, but certain key themes tend to crop up time and again. The three themes that we will examine in this paper are (i) the nature and behaviour of the ordinary concept of truth, (ii) the meaning of discourse about truth, and (iii) the nature of the property truth. We will start by offering a brief overview of the debates centring on these themes. We will then argue that cross-linguistic experimental philosophy has an indispensable yet (...) underappreciated role to play in all of these debates. Recognising the indispensability of cross-linguistic experimental philosophy should compel philosophers to significantly revise the ways in which they inquire about truth. It should also prompt analytic philosophers more generally to consider whether similar revisions might be necessary elsewhere in the field. (shrink)

Through a series of empirical studies involving native speakers of English, German, and Chinese, this paper reveals that the predicate “true” is inherently ambiguous in the empirical domain. Truth statements such as “It is true that Tom is at the party” seem to be ambivalent between two readings. On the first reading, the statement means “Reality is such that Tom is at the party.” On the second reading, the statement means “According to what X believes, Tom is at the party.” (...) While there appear to exist some cross-cultural differences in the interpretation of the statements, the overall findings robustly indicate that “true” has multiple meanings in the realm of empirical matters.

Traditionally, the investigation of truth has been anchored in a priori reasoning. Cognitive science deviates from this tradition by adding empirical data on how people understand and use concepts. Building on psychophysics and machine learning methods, we introduce conceptual scaling, an approach to map people's understanding of abstract concepts. This approach, allows computing participant-specific conceptual maps from obtained ordinal comparison data, thereby quantifying perceived similarities among abstract concepts. Using this approach, we investigated individual's alignment with philosophical theories on truth and (...) the predictive capacity of conceptual maps. The obtained results indicated that, while people's understanding of truth is multifaceted and encapsulates notions of coherence and authenticity, alignment is best for the correspondence theory of truth. Furthermore, conceptual maps allowed predicting individual outcomes with an accuracy of roughly 70%. This research demonstrates that conceptual scaling offers accurate descriptions of individual's understanding of abstract concepts, behavioral predictions, and quantification of alignment with theoretical perspectives.

This chapter reviews empirical research on the rules governing assertion and retraction, with a focus on the normative role of truth. It examines whether truth is required for an assertion to be considered permissible, and whether there is an expectation that speakers retract statements that turn out to be false. Contrary to factive norms (such as the influential “knowledge norm”), empirical data suggests that there is no expectation that speakers only make true assertions. Additionally, contrary to truth-relativist accounts, there is (...) no requirement for speakers to retract statements that are false at the context of assessment. We conclude by suggesting that truth still plays a crucial role in the evaluation of assertions: as a standard for evaluating their success, rather than permissibility. (shrink)

In the last decade Robert Barnard and Joseph Ulatowski have conducted a number of experimental studies in order to better understand the ordinary notion of truth. In this paper I critically engage their ecological approach to the study of truth, and argue for a wider perspective on how truth should be empirically studied: in addition to the experimental data that they emphasize and collect, there should also be a substantial observational element to conceptual ecology. I then critically evaluate the conclusions (...) they draw from their data, as they relate to correspondence, pluralism, and objectivity. Along the way, I offer suggestions for future lines of research for a more expansive and effective ecological exploration of truth. (shrink)

Conceptual engineering is a philosophical method that aims to design and spread conceptual and linguistic devices to cause meaningful changes in the world. So far, however, conceptual engineers have struggled to successfully spread the conceptual and linguistic entities they have designed to their target communities. This paper argues that conceptual engineering is far more likely to succeed if it incorporates empirical data and empirical methods. Because the causal factors influencing successful propagation of linguistic or conceptual devices are as complicated and (...) interwoven as they are, proper empirical research will greatly boost the likelihood that propagation is successful. In arguing for the superiority of empirical conceptual engineering over armchair-based conceptual engineering, this paper proposes a framework for understanding the causal forces at play in propagation. This is a three-part framework between the label of a lexical item, the psychological states associated with the lexical item, and the worldly things associated with the lexical item. By understanding the way causal forces affecting propagation play out at these three levels, conceptual engineers can better conceptualize, study, and harness the different causal forces affecting the success of their conceptual engineering projects.

Technologies can have profound effects on social moral systems. Is there any way to systematically investigate and anticipate these potential effects? This paper aims to contribute to this emerging field on inquiry through a case study method. It focuses on two core human values—truth and trust—describes their structural properties and conceptualisations, and then considers various mechanisms through which technology is changing and can change our perspective on those values. In brief, the paper argues that technology is transforming these values by (...) changing the costs/benefits of accessing them; allowing us to substitute those values for other, closely-related ones; increasing their perceived scarcity/abundance; and disrupting traditional value-gatekeepers. This has implications for how we study other, technologically-mediated, value changes. (shrink)

There are many variants of deflationism about truth, but one of them, Paul Horwich’s minimalism, stands out because it accepts as axiomatic practical variants of the equivalence schema: 〈p〉 is true if and only if p. The equivalence schema is epistemologically fundamental. In this paper, I call upon empirical studies to show that practical variants of the equivalence schema are widely accepted by non-philosophers. While in the empirical data there is variation in how non-philosophers and philosophers talk about truth and (...) how they judge that a proposition is true, a significant amount of data collected over the years reveal that the ordinary or folk view of truth is compatible with the epistemological fundamentality of alethic minimalism. This, I take it, suggests that people share in the same intuitions that form the bedrock of Horwich’s minimalism. (shrink)

A familiar form of alethic pluralism is built on the view that while there is a single concept of truth, there are multiple properties associated with it. A newer form of alethic pluralism develops the view that there are multiple concepts of truth. Importantly, this form of pluralism has been offered an empirical footing, notably in the work of Barnard and Ulatowski, Mizumoto, and Wyatt. My paper offers a critical appraisal of that project: while the appeal to empirical data is (...) a welcome addition to the philosophy of truth, I doubt that it supports conceptual pluralism. First, I argue that there are severe challenges involved in the very formulation of conceptual pluralism about truth: it risks being an incoherent thesis. Once that problem is addressed, I review the empirical data that have been associated with the thesis, and argue that the evidence points not toward a plurality of truth concepts but rather a plurality of theories about truth.

In The Metaphysics of Truth, Doug Edwards offers a sustained case against deflationism about truth and in favour of his preferred pluralist theory of truth. Here, I take up three of the main components of that case. The first is Edwards' account of the distinctive metaphysical commitments of deflationism. His views about this issue have changed over the past few years, and I detail these changes as well as a concern for the views that he develops in the book. Second, (...) I take up the argument that Edwards offers for thinking that deflationism is, in a certain sense, internally unstable. I explain why this argument is inconclusive, outlining three responses to it on behalf of the deflationist. Third, I consider Edwards' novel argument for truth pluralism, which acts as an indirect argument against deflationism. After sorting out some interpretive nuances related to the use of definite descriptions in this argument, I show how the deflationist can resist it. Having responded to Edwards' critique of deflationism, I close by briefly explaining why I take the methodology of deflationism to be especially promising, insofar as it underscores the significance of empirically-informed inquiry about truth.

Critics of the scope problem that motivates pluralism about truth have argued that it is a pseudo-problem. If the criticism is correct, then truth pluralism is left unmotivated and potentially bankrupt. In this paper, I argue that closely related to the scope problem is another problem, which I call “the scalar problem.” If the property of truth is sensitive to how an agent expresses the truth predicate within a single linguistic discourse and different agents or groups of agents express truth (...) differently within that discourse, then there are different ways of being true within the same linguistic discourse. Given this possibility, even if the scope problem fails, truth pluralism remains fully motivated. Keywords: alethic pluralism, truth, Quine-Sainsbury problem, experimental philosophy. (shrink)
