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.

We apply the recently elaborated notions of 'pragmatic truth' and 'pragmatic probability' to the problem of the construction of a logic of inductive inference. It is argued that the system outlined here is able to overcome many of the objections usually levelled against such attempts. We claim, furthermore, that our view captures the essentially cumulative nature of science and allows us to explain why it is indeed reasonable to accept and believe in the conclusions reached by inductive inference.

It is a truism that people speak ‘loosely’——that is, that they often say things that we can recognize not to be true, but which come close enough to the truth for practical purposes. Certain expressions. such as those including ‘exactly’, ‘all’ and ‘perfectly’, appear to serve as signals of the intended degree of approximation to the truth. This article presents a novel formalism for representing the notion of approximation to the truth, and analyzes the meanings of these expressions in terms of this formalism. Pragmatic loosencss of this kind should be distinguished from authentic truth-conditional vagueness.

Abstract Some fictions, it seems, represent the future as closed, in the sense that some future-tensed propositions are true in those fictions. Yet it is surprisingly difficult to accommodate this plausible thesis within an account of truth in fiction. A number of putative examples of closed fictional futures are discussed (Macbeth, Oedipus, Time and the Conways, The Time Machine) and the problems encountered in reconciling them with various accounts of truth in fiction (David Lewis', Gregory Currie's, Alex Byrne's) elaborated. Connections are drawn between metaphysical views on time and theories of fiction, and an attempt is made to show how the tenseless theory of time (roughly, the denial that time flows) can illuminate accounts of fictional truth, and in particular the issue of how there can be true beliefs about what will happen in a fiction.

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.

Some things are left open by a work of fiction. What colour were the hero’s eyes? How many hairs are on her head? Did the hero get shot in the final scene, or did the jailor complete his journey to redemption and shoot into the air? Are the ghosts that appear real, or a delusion? Where fictions are open or incomplete in this way, we can ask what attitudes it’s appropriate (or permissible) to take to the propositions in question, in engaging with the fiction. In Mimesis as Make-Believe (henceforth, MMB), Walton argues that just as truth norms belief, truth-in-fiction norms imagination. Granting that what is true-in-the-fiction should be imagined, and what is false-in-the-fiction is not to be imagined, there remains the question of what to say within the Waltonian framework about things that are neither true- nor false-in-the-fiction---the loci of incompleteness.

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.

Fiction is often characterized by way of a contrast with truth, as, for example, in the familiar couplet “Truth is always strange/ Stranger than fiction" (Byron 1824). And yet, those who would maintain that “we will always learn more about human life and human personality from novels than from scientific psychology” (Chomsky 1988: 159) hold that some truth is best encountered via fiction. The scrupulous novelist points out that her work depicts no actual person, either living or dead; nonetheless, we use names from fiction in ways that suggest that we take these names to refer. Philosophers who investigate fiction aim to reconcile such apparently incompatible phenomena, and, in general, to account for the myriad ways that we talk, think, and feel about fiction.
