In his book Truth and Justification Habermas replaces his long-held discourse-theoretic conception of truth with what he calls a pragmatic theory of truth. Instead of taking truth to originate in the communicative interactions between subjects, this new theory ties truth to the action contexts of the lifeworld, contexts where the existence of the world is ratified in practice. This, Habermas argues, overcomes the relativism and contextualism endemic to the linguistic turn. This article has two goals: (1) to chart in detail how Habermas’ new theory of truth overcomes relativism and contextualism; and (2) to argue for the thesis that Habermas’ specific way of meeting this objective is flawed insofar as he resists relativism and contextualism by yoking truth to a concept of objectivity that is not consistent with the larger pragmatic transformation of his thought.

Recent research (e.g., Evans & Over, 2004) has provided support for the hypothesis that people evaluate the probability of conditional statements of the form if p then q as the conditional probability of q given p , P( q / p ). The present paper extends this approach to pragmatic conditionals in the form of inducements (i.e., promises and threats) and advice (i.e., tips and warnings). In so doing, we demonstrate a distinction between the truth status of these conditionals and their effectiveness as speech acts. Specifically, while probability judgements of the truth of conditional inducements and advice are highly correlated with estimates of P( q / p ), their perceived effectiveness in changing behaviour instead varies as a function of the conditional probability of q given not-p , P( q / ∼p ). Finally, we show that the conditional probability approach can be extended to predicting inference rates on a conditional reasoning task.

I argue that conventional implicatures embed in logical compounds, and are non-truth-conditional contributors to sentence meaning. This, I argue has significant implications for how we understand truth, truth-conditional content, and truth-bearers.

This article defends a pragmatic conception of objectivity for the moral domain. I begin contextualizing pragmatic approaches to objectivity and discuss at some length one of the most interesting proposals in this area, Cheryl Misak’s conception of pragmatic objectivity. My general argument is that in order to defend a pragmatic approach to objectivity the pragmatic stance should be interpreted in more radical terms than most contemporary proposals do. I propose notably to disentangle the connection between objectivity and truth, claiming that moral inquiry is in most of the cases responsive to a discursive norm that is closer to warranted assertibility than to truth. Using an argument that relies partly on Huw Price's account of forms of normative assertion, I will show that a practice-based account of warranted assertibility does the epistemic work required to defend objectivity while not being exposed to the criticisms that are usually addressed against this notion. The first section sets the general argument within its pragmatic context. The second section outlines Misak's conception of pragmatic objectivity, and highlights the sense in which she makes moral objectivity depend upon truth. The third and the fourth sections provide two critical arguments against Misak's thesis. Finally, with the critical work done, in the last section I present my constructive account of pragmatic objectivity for the moral domain.

Philosophers are interested in a constellation of issues involving the concept of truth. A preliminary issue, although somewhat subsidiary, is to decide what sorts of things can be true. Is truth a property of sentences (which are linguistic entities in some language or other), or is truth a property of propositions (nonlinguistic, abstract and timeless entities)? The principal issue is: What is truth? It is the problem of being clear about what you are saying when you say some claim or other is true. The most important theories of truth are the Correspondence Theory, the Semantic Theory, the Deflationary Theory, the Coherence Theory, and the Pragmatic Theory. They are explained and compared here. Whichever theory of truth is advanced to settle the principal issue, there are a number of additional issues to be addressed: i. Can claims about the future be true now? ii. Can there be some algorithm for finding truth – some recipe or procedure for deciding, for any claim in the system of, say, arithmetic, whether the claim is true? iii. Can the predicate “is true” be completely defined in other terms so that it can be eliminated, without loss of meaning, from any context in which it occurs? iv. To what extent do theories of truth avoid paradox? v. Is the goal of scientific research to achieve truth? Table of Contents..

C.S. Peirce, the founder of pragmatism, argued that truth is what we would agree upon, were inquiry to be pursued as far as it could fruitfully go. In this book, Misak argues for and elucidates the pragmatic account of truth, paying attention both to Peirce's texts and to the requirements of a suitable account of truth. An important argument of the book is that we must be sensitive to the difference between offering a definition of truth and engaging in a distinctively pragmatic project. The pragmatic project spells out the relationship between truth and inquiry; it articulates the consequences of a statement's being true. The existence of a distinct pragmatic enterprise has implications for the status of the pragmatic account of truth and for the way in which philosophy should be conducted.

The mathematical concept of pragmatic truth, first introduced in Mikenberg, da Costa and Chuaqui (1986), has received in the last few years several applications in logic and the philosophy of science. In this paper, we study the logic of pragmatic truth, and show that there are important connections between this logic, modal logic and, in particular, Jaskowski's discussive logic. In order to do so, two systems are put forward so that the notions of pragmatic validity and pragmatic truth can be accommodated. One of the main results of this paper is that the logic of pragmatic truth is paraconsistent. The philosophical import of this result, which justifies the application of pragmatic truth to inconsistent settings, is also discussed.

Why is truth valuable? Why are true beliefs generally preferable to false beliefs and why should we often be willing to expend energy and resources to obtain the truth? Pragmatist theories of truth, whatever their shortcomings, are the only ones which attempt to answer these questions. According to James’ version of the pragmatic theory.
