Fixpoint semantics are provided for ambiguity blocking and propagating variants of Nute's defeasible logic. The semantics are based upon the well-founded semantics for logic programs. It is shown that the logics are sound with respect to their counterpart semantics and complete for locally finite theories. Unlike some other nonmonotonic reasoning formalisms such as Reiter's default logic, the two defeasible logics are directly skeptical and so reject floating conclusions. For defeasible theories with transitive priorities on defeasible rules, the logics are shown (...) to satisfy versions of Cut and Cautious Monotony. For theories with either conflict sets closed under strict rules or strict rules closed under transposition, a form of Consistency Preservation is shown to hold. The differences between the two logics and other variants of defeasible logic—specifically those presented by Billington, Antoniou, Governatori, and Maher—are discussed. (shrink)

A fictional text is commonly viewed as constituting an invitation to play a certain game of make-believe, with the individual sentences written by the author providing the propositions we are to imagine and/or accept as true within the fiction. However, we can’t always take the text at face value. What narratologists call ‘unreliable narrators’ may present a confused or misleading picture of the fictional world. Meanwhile there has been a debate in philosophy about so-called ‘imaginative resistance’ in which we are (...) inclined to resist imagining (or even accepting as true in the fiction) what’s explicitly stated in the text. But if we can’t take the text’s word for it, how do we determine what’s true in a fiction? We propose an account of fiction interpretation in a dynamic setting (a version of DRT with a mechanism for opening, updating, and closing temporary ‘workspaces’) and combine this framework with belief revision logic. With these tools in hand we turn to modelling imaginative resistance and unreliable narrators. (shrink)

Semantics traditionally focuses on linguistic meaning. In recent years, the Super Linguistics movement has tried to broaden the scope of inquiry in various directions, including an extension of semantics to talk about the meaning of pictures. There are close similarities between the interpretation of language and of pictures. Most fundamentally, pictures, like utterances, can be either true or false of a given state of affairs, and hence both express propositions (Zimmermann, 2016; Greenberg, 2013; Abusch, 2015). Moreover, sequences of pictures, like (...) sequences of utterances, can be used to tell stories. Wordless picture books, comics, and film are cases in point. In this paper I pick up the project of providing a dynamic semantic account of pictorial story-telling, started by Abusch (2012) and continued by Abusch & Rooth (2017); Maier & Bimpikou (2019); Fernando (2020). More specifically, I propose here a semantics of speech and thought bubbles by adding event reference to PicDRT. To get there I first review the projection-based semantics for pictures (section 1), noting the fundamental distinction between symbolic and iconic meaning that makes speech bubbles especially interesting (section 2). I then review the dynamic PicDRT framework for pictorial narratives (section 3), add events (section 4), and propose an account of speech bubbles as quotational event modification (section 5). I end with a brief look at other conventional, symbolic enrichments in comics (section 6). (shrink)

I argue that emojis are essentially little pictures, rather than words, gestures, expressives, or diagrams. ???? means that the world looks like that, from some viewpoint. I flesh out a pictorial semantics in terms of geometric projection with abstraction and stylization. Since such a semantics delivers only very minimal contents I add an account of pragmatic enrichment, driven by coherence and nonliteral interpretation. The apparent semantic distinction between emojis depicting entities (like ????) and those depicting facial expressions (like ????) I (...) analyze as a difference between truth-conditional and use-conditional pictorial content: ???? depicts what the world of evaluation looks like, while ???? depicts what the utterance context looks like.

Quotation exhibits characteristics of both use and mention. I argue against the recently popular pragmatic reductions of quotation to mere language use (Recanati 2001), and in favor of a truly hybrid account synthesizing and extending Potts (2007) and Geurts and Maier (2005), using a mention logic and a dynamic semantics with presupposition to establish a context-driven meaning shift. The main advantages are an account of error neutralization and shifted indexicality under quotation. The current paper addresses the problematic data involving (...) quoted non-constituents.

Critics of Divine Command Theory (DCT) have advanced the counterpossible terrible commands objection. They argue that DCT implies the counterpossible ‘If a necessarily morally perfect God commanded us to perform a terrible act, then the terrible act would be morally obligatory.’ However, this counterpossible is false. Hence, DCT is false. Philipp Kremers has proposed that the intuition that the counterpossible above is false is due to conversational implicatures. By providing a pragmatic explanation for the intuition, he thinks that DCT proponents (...) can then maintain that the counterpossible is actually true. In this article, I argue that Kremers's conversational implicature response fails because (a) there is good reason to think that no conversational implicature arises given what critics of DCT have expressed, (b) a competent reader would not understand the critics' utterance that TCC is false as implicating that TCC* is false, and (c) the counterpossible terrible commands objection can be easily modified to be immune to the conversational implicature response by cancelling any potential implicature. Thus, an appeal to conversational implicatures cannot save DCT from the counterpossible terrible commands objection. (shrink)

The central characteristic of denials is that they perform a non-monotonic correction operation on discourse structure. A second characteristic is that they may be used to object to various kinds of information including presuppositions and implicatures. In this paper we first use standard DRT to capture these features, implement an earlier proposal of van der Sandt (1991) in DRT and point out a shortcoming of that approach. We then adopt Layered DRT. LDRT is an extension of standard DRT designed to (...) represent and interpret different types of information conveyed in a conversation by distributing them over separate layers of the same LDRS. We will then show how LDRT allows us to solve the problems of the classic monostratal system. The resulting system makes use of a directed reverse anaphora mechanism to locate, remove and negate the material objected to. (shrink)

We propose to analyze well-known cases of "imaginative resistance" from the philosophical literature (Gendler, Walton, Weatherson) as involving the inference that particular content should be attributed to either: (i) a character rather than the narrator or, (ii) an unreliable, irrational, opinionated, and/or morally deviant "first person" narrator who was originally perceived to be a typical impersonal, omniscient, "effaced" narrator. We model the latter type of attribution in terms of two independently motivated linguistic mechanisms: accommodation of a discourse referent (Lewis, Stalnaker, (...) Kamp) and 'cautious' updating as a model of non-cooperative information exchange (Eckardt). (shrink)

A new approach to understanding the nature of ethics and ethical decision making, not only in the context of business, but also in other life contexts.

One of the very few accounts in English of German idealism, this ambitious work advances and revises our understanding of both the history and the thought of the classical period of German philosophy. As he traces the structure and evolution of idealism as a doctrine, Frederick Beiser exposes a strong objective, or realist, strain running from Kant to Hegel and identifies the crucial role of the early romantics—Hölderlin, Schlegel, and Novalis—as the founders of absolute idealism.

The Fate of Reason is the first general history devoted to the period between Kant and Fichte, one of the most revolutionary and fertile in modern philosophy.

That about sums up what is wrong with Clark's view.

Hannah Arendt disavowed the title of “philosopher,” and is known above all as a political theorist. But the relationship between philosophy and politics animates her entire oeuvre. We find her addressing the topic in The Human Condition (1958), in Between Past and Future (a collection of essays written in the early 1960s), and in Men in Dark Times (another collection of essays, this one from the late sixties). It is treated in her Lectures on Kant’s Political Philosophy, composed during the (...) seventies, and also in the posthumous Life of the Mind, two of three projected volumes of which were complete when she died in 1975. Certainly, Arendt’s thought cannot be understood without taking into account her deep suspicion of and equally deep commitment to philosophy in the context of political reflection. For all that, her writings on this abiding preoccupation do not gel into a systematically articulated theory or programmatic statement. Instead, they reflect Arendt’s appreciation of what remained for her a “vital tension” – an enigma. (shrink)

Hegel is one of the major philosophers of the nineteenth century. Many of the major philosophical movements of the twentieth century - from existentialism to analytic philosophy - grew out of reactions against Hegel. He is also one of the hardest philosophers to understand and his complex ideas, though rewarding, are often misunderstood. In this magisterial and lucid introduction, Frederick Beiser covers every major aspect of Hegel's thought. He places Hegel in the historical context of nineteenth-century Germany whilst clarifying (...) the deep insights and originality of Hegel's philosophy. A masterpiece of clarity and scholarship, _Hegel_ is both the ideal starting point for those coming to Hegel for the first time and essential reading for any student or scholar of nineteenth century philosophy. Additional features: glossary chapter summaries chronology annotated further reading. (shrink)

Histories of German philosophy in the nineteenth century typically focus on its first half--when Hegel, idealism, and Romanticism dominated. By contrast, the remainder of the century, after Hegel's death, has been relatively neglected because it has been seen as a period of stagnation and decline. But Frederick Beiser argues that the second half of the century was in fact one of the most revolutionary periods in modern philosophy because the nature of philosophy itself was up for grabs and the (...) very absence of certainty led to creativity and the start of a new era. In this innovative concise history of German philosophy from 1840 to 1900, Beiser focuses not on themes or individual thinkers but rather on the period's five great debates: the identity crisis of philosophy, the materialism controversy, the methods and limits of history, the pessimism controversy, and the Ignorabimusstreit. Schopenhauer and Wilhelm Dilthey play important roles in these controversies but so do many neglected figures, including Ludwig Büchner, Eugen Dühring, Eduard von Hartmann, Julius Fraunstaedt, Hermann Lotze, Adolf Trendelenburg, and two women, Agnes Taubert and Olga Pluemacher, who have been completely forgotten in histories of philosophy. The result is a wide-ranging, original, and surprising new account of German philosophy in the critical period between Hegel and the twentieth century. (shrink)

Neo-Kantianism was an important movement in German philosophy of the late 19th century: Frederick Beiser traces its development back to the late 18th century, and explains its rise as a response to three major developments in German culture: the collapse of speculative idealism; the materialism controversy; and the identity crisis of philosophy.

This book defends a comprehensive new vision of what addiction is and how people with addictions should be treated. The author argues that, in addition to physical and intellectual disabilities, there are volitional disabilities – disabilities of the will – and that addiction is best understood as a species of volitional disability. -/- This theory serves to illuminate long-standing philosophical and psychological perplexities about addiction and addictive motivation. It articulates a normative framework within which to understand prohibition, harm reduction, and (...) other strategies that aim to address addiction. The argument of this book is that these should ultimately be evaluated in terms of reasonable accommodations for addicted people and that the priority of addiction policy should be the provision of such accommodations. What makes this book distinctive is that it understands addiction as a fundamentally political problem, an understanding that is suggested by standard legal approaches to addiction, but which has not received a sustained defense in the previous philosophical or psychological literature. -/- This text marks a significant advance in the theory of addiction, one which should reshape our understanding of addiction policy and its proper aims.

This is the first full study in English of the German historicist tradition. Frederick C. Beiser surveys the major German thinkers on history from the middle of the eighteenth century until the early twentieth century, providing an introduction to each thinker and the main issues in interpreting and appraising his thought. The volume offers new interpretations of well-known philosophers such as Johann Gottfried Herder and Max Weber, and introduces others who are scarcely known at all, including J. A. Chladenius, (...) Justus Möser, Heinrich Rickert, and Emil Lask. Beyond an exploration of the historical and intellectual context of each thinker, Beiser illuminates the sources and reasons for the movement of German historicism—one of the great revolutions in modern Western thought, and the source of our historical understanding of the human world.

This book is the first comprehensive study of Rousseau's rich and complex theory of the type of self-love (amour proper) that, for him, marks the central difference between humans and the beasts. Amour proper is the passion that drives human individuals to seek the esteem, approval, admiration, or love--the recognition--of their fellow beings. Neuhouser reconstructs Rousseau's understanding of what the drive for recognition is, why it is so problematic, and how its presence opens up far-reaching developmental possibilities for creatures that (...) possess it. One of Rousseau's central theses is that amour proper in its corrupted, manifestations--pride or vanity--is the principal source of an array of evils so widespread that they can easily appear to be necessary features of the human condition: enslavement, conflict, vice, misery, and self-estrangement. Yet Rousseau also argues that solving these problems depends not on suppressing or overcoming the drive for recognition but on cultivating it so that it contributes positively to the achievement of freedom, peace, virtue, happiness, and unalienated selfhood. Indeed, Rousseau goes so far as to claim that, despite its many dangers, the need for recognition is a condition of nearly everything that makes human life valuable and that elevates it above mere animal existence: rationality, morality, freedom--subjectivity itself--would be impossible for humans if it were not for amour proper and the relations to others it impels us to establish.

Weltschmerz is a study of the pessimism that dominated German philosophy in the second half of the nineteenth century. Pessimism was essentially the theory that life is not worth living, and was introduced into German philosophy by Schopenhauer. Frederick C. Beiser examines the intense and long controversy that arose from Schopenhauer's pessimism, which changed the agenda of philosophy in Germany away from the logic of the sciences and toward an examination of the value of life. He examines the major (...) defenders of pessimism and its chief critics, especially Eugen Dühring and the neo-Kantians. The pessimism dispute of the second half of the century has been largely ignored in secondary literature and this book is a first attempt since the 1880s to re-examine it and to analyze the important philosophical issues raised by it. The dispute concerned the most fundamental philosophical issue of them all: whether life is worth living. (shrink)

The Fate of Reason is the first general history devoted to the period between Kant and Fichte, one of the most revolutionary and fertile in modern philosophy. The philosophers of this time broke with the two central tenets of the modem Cartesian tradition: the authority of reason and the primacy of epistemology. They also witnessed the decline of the Aufkldrung, the completion of Kant's philosophy, and the beginnings of post-Kantian idealism. Thanks to Beiser we can newly appreciate the influence of (...) Kant's critics on the development of his philosophy. Beiser brings the controversies, and the personalities who engaged in them, to life and tells a story that has uncanny parallels with the debates of the present. (shrink)
