Introduction IT is generally agreed that Charles Sanders Peirce was one of America's greatest philosophers, yet even today there is little agreement as to ...

The aim of this paper is twofold: (i) to introduce the framework of update semantics and to explain what kind of semantic phenomena may successfully be analysed in it: (ii) to give a detailed analysis of one such phenomenon: default reasoning.

Charles S. Peirce (1839-1914) made relevant contributions to deductive logic, but he was primarily interested in the logic of science, and more especially in what he called 'abduction' (as opposed to deduction and induction), which is the process whereby hypotheses are generated in order to explain the surprising facts. Indeed, Peirce considered abduction to be at the heart not only of scientific research, but of all ordinary human activities. Nevertheless, in spite of Peirce's work and writings in the field of (...) methodology of research, scarce attention has been paid to the logic of discovery over the last hundred years, despite an impressive development not only of scientific research but also of logic. -/- Having this in mind, the exposition is divided into five parts: 1) a brief presentation of Peirce, focusing on his work as a professional scientist; 2) an exposition of the classification of inferences by the young Peirce: deduction, induction and hypothesis; 3) a sketch of the notion of abduction in the mature Peirce; 4) an exposition of the logic of surprise; and finally, by way of conclusion, 5) a discussion of this peculiar ability of guessing understood as a rational instinct. -/- .

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. (shrink)

In 1934 Charles W. Morris, then a young philosopher at the University of Chicago, visited Rudolf Carnap in Prague, where the latter was teaching on the science faculty of Charles University. Morris, a philosopher familiar with Peirce’s work and himself following the traditions of pragmatism, was impressed with the positivist program. Two years later he played an important role in Carnap’s move to a professorship at the University of Chicago. In the following year, 1937, Hermann in Paris published a slim (...) but eloquent book by Morris, Pragmatism, Logical Positivism, and Scientific Empiricism. Its thesis was that American pragmatism and European positivism were entirely complementary philosophical movements, and that the collaboration of the adherents of the two could lead to a new form of scientific empiricism more fruitful than either.

In this paper, I present a new semantics for demonstratives. Now some may think that David Kaplan (1989a,b) has already given a more than satisfactory semantics for demonstratives, and that there is no need for a new one. But I argue below that Kaplan's theory fails to describe the linguistic meanings of 'that' and other true demonstratives. My argument for this conclusion has nothing to do with cognitive value, belief sentences, or other such contentious matters in semantics and the philosophy (...) of mind. Rather, it appeals to the obvious fact that there can be true utterances of certain sentences containing several occurrences of the same demonstrative (for instance, 'That is taller than that'). My argument can be answered by making a fairly modest revision in Kaplan's theory. But I believe that the resulting revised version of Kaplan's theory ignores or distorts various important semantic features of 'that'. Thus I ultimately argue in favor of a more substantial departure from Kaplan's theory. Perhaps the most remarkable feature of the theory I favor is that it ascribes three distinct sorts of meanings to demonstratives. (shrink)

This paper traces a lost genealogical connection between Charles S. Peirce’s later theory of signs and contemporary work in the philosophy of language by John Perry. As is shown, despite some differences, both accounts offer what might be termed a multi-level account of meaning. Moreover, it is claimed that by adopting a ‘Peircian turn’ in his theory, Perry might overcome alleged shortcomings in his account of cognitive significance.

Following his recently expanded _The Problem of the Essential Indexical and Other Essays,_ John Perry develops a reflexive-referential' account of indexicals, demonstratives and proper names. On these issues the philosophy of language in the twentieth century was shaped by two competing traditions, descriptivist and referentialist. Oddly, the classic referentialist texts of the 1970s by Kripke, Donnellan, Kaplan and others were seemingly refuted almost a century earlier by co-reference and no-reference problems raised by Russell and Frege. Perry's theory, borrowing ideas from (...) both traditions as well as from Burks and Reichenbach, diagnoses the problems as stemming from a fixation on a certain kind of content, coined referential or fully incremental. Referentialist tradition is portrayed as holding that indexicals contribute content that involves individuals without identifying conditions on them; descriptivist tradition is portrayed as holding that referential content does not explain all of the identifying conditions conveyed by names and indexicals. Perry reveals a coherent and structured family of contents — from reflexive contents that place conditions on their actual utterance to fully incremental contents that place conditions only on the objects of reference — reconciling the legitimate insights of both traditions.

We discuss presupposition, the phenomenon whereby speakers mark linguistically the information that is presupposed or taken for granted, rather than being part of the main propositional content of a speech act. Expressions and constructions carrying presuppositions are called “presupposition triggers”, forming a large class including definites and factive verbs. The article first introduces the range of triggers, the basic properties of presuppositions such as projection and cancellability, and the diagnostic tests used to identify them. The reader is then introducedto major (...) models of presupposition from the last 50 years, separated into three classes: Frege-Strawson derived semantic models, pragmaticmodels such as that offered by Stalnaker, and dynamic models. Finallywe discuss some of the main current issues in presupposition theory. These involve accommodation, which occurs when a hearer's knowledge state is adjusted to meet the speaker's presuppositions; presupposition failure, which occurs when a presupposition is false; the interaction between presuppositions and attitudes; and the triggering problem, i.e., the problem of explaining why presuppositions occur in the first place.
