Several philosophers have proposed Knowledge-Based Decision Theories (KDTs)—theories that require agents to maximize expected utility as yielded by utility and probability functions that depend on the agent’s knowledge. Proponents of KDTs argue that such theories are motivated by Knowledge-Reasons norms that require agents to act only on reasons that they know. However, no formal derivation of KDTs from Knowledge-Reasons norms has been suggested, and it is not clear how such norms justify the particular ways in which KDTs relate knowledge and (...) rational action. In this paper, I suggest a new axiomatic method for justifying KDTs and providing them with stronger normative foundations. I argue that such theories may be derived from constraints on the relation between knowledge and preference, and that these constraints may be evaluated relative to intuitions regarding practical reasoning. To demonstrate this, I offer a representation theorem for a KDT proposed by Hawthorne and Stanley (2008) and briefly evaluate it through its underlying axioms. -/- In section 1, I present knowledge-based decision theories generally and the versions of such theories suggested in the literature. In section 2, I argue that KDTs and theories of practical reasoning conjoined with Knowledge-Reasons norms generate constraints on the same relation—the relation between knowledge and preference. In section 3, I present a formal framework in which constraints on this relation may be expressed and from which KDTs may be derived. In section 4, I present a representation theorem for a specific KDT. In section 5, I briefly evaluate the axioms of the theory, and in section 6, I conclude. (shrink)

Ces etudes debordent le probleme du temps chez les Stoiciens et se proposent d'etablir que cette question, en apparence modeste, permet d'eclairer, et en meme temps commande l'ensemble du systeme. Au premier abord en effet, la theorie du temps se presente comme une simple section d'un chapitre de la Physique, celui qui traite des Incorporels. Mais deja la simple interpretation des textes transmis fait voir que cette theorie tient etroitement a d'autres theories, comme celle des incorporels en general, des categories, (...) de la substance. Abordant ensuite les theses majeures de la logique et de l'ethique, on s'apercoit qu'a leur tour elles sont solidaires de la conception du temps qui, dans bien des cas, fait evanouir leur apparence de paradoxe. A cela meme, il n'y a rien d'etrange, si l'on se souvient que le stoicisme, plus que tout autre philosophie antique, constitue un systeme coherent. Mais plus particulierement, le probleme du temps a du former comme le noeud de la reflexion stoicienne qui vise, contre les lourdes autorites de Platon et d'Aristote, a retablir dans sa realite et dans sa dignite, le concret, le sensible, disqualifie comme sujet a la generation et a la corruption, c'est-a-dire, en un mot, comme l'etre dans le temps.

Wittgenstein finished part 1 of the Philosophical Investigations in the spring of 1945. From 1946 to 1949 he worked on the philosophy of psychology almost without interruption. The present two-volume work comprises many of his writings over this period. Some of the remarks contained here were culled for part 2 of the Investigations ; others were set aside and appear in the collection known as Zettel . The great majority, however, although of excellent quality, have hitherto remained unpublished. This bilingual (...) edition of the Remarks on the Philosophy of Psychology presents the first English translation of an essential body of Wittegenstein's work. It elaborates Wittgenstein's views on psychological concepts such as expectation, sensation, knowing how to follow a rule, and knowledge of the sensations of other persons. It also shows strong emphasis on the "anthropological" aspect of Wittgenstein's thought. Philosophers, as well as anthropologists, psychologists, and sociologists will welcome this important publication. (shrink)

Jürgen Habermas vertritt die These, dass sich das Konsensprinzip des kommunikativen Handelns in den Meinungs- und Willensbildungsprozess der Politik übertragen lasse. In der vorliegenden grundlegenden Kritik zeigt die Autorin, dass diese These nicht haltbar ist. Anders als Habermas annimmt, findet kommunikatives Handeln keinen Eingang in die Prozeduralität der Politik. Das politische Handeln wird vielmehr durch systemische Vorgaben bestimmt. Diese ergeben sich im Wesentlichen aus der Prozeduralität des ökonomischen Systems sowie aus der über Macht bestimmten Prozeduralität des politischen Systems selbst.

Intellectual diary of a thinker of the school of Logical Positivism showing the day-by-day development of his philosophical ideas.

Bazzocchi disposes the text of the Tractatus in a user-friendly manner, exactly as Wittgenstein's decimals advise. This discloses the logical form of the book by distinct reading units, linked into a fashioned hierarchical tree. The text becomes much clearer and every reader can enjoy, finally, its formal and literary qualities.

Philosopher Ludwig Wittgenstein had an enormous influence on twentieth-century philosophy even though only one of his works, the famous Tractatus Logico-Philosophicus, was published in his lifetime. Beyond this publication the impact of his thought was mainly conveyed to a small circle of students through his lectures at Cambridge University. Fortunately, many of his ideas have survived in both the dictations that were subsequently published, and the notes taken by his students, among them Alice Ambrose and the late Margaret Macdonald, (...) from 1932 to 1935. These notes, now edited by Professor Ambrose, are here published, and they shed much light on Wittgenstein's philosophical development. Among the topics considered are the meaning of a word and its relation to common usage, rules of grammar and their relation to fact, the grammar of first person statements, language games, and the nature of philosophy. This volume is indispensable to any serious discussion of Wittgenstein's work. (shrink)

Written in code under constant threat of battle, Wittgenstein's searing and illuminating diaries finally emerge in this first-ever English translation. During the pandemic, Marjorie Perloff, one of our foremost scholars of global literature, found her mind ineluctably drawn to the profound commentary on life and death in the wartime diaries of eminent philosopher Ludwig Wittgenstein (1889-1951). Upon learning that these notebooks, which richly contextualize the early stages of his magnum opus, the Tractatus-Logico-Philosophicus, had never before been published in English, (...) the Viennese-born Perloff determinedly set about translating them. Beginning with the anxious summer of 1914, this historic, en-face edition presents the first-person recollections of a foot soldier in the Austrian Army, fresh from his days as a philosophy student at Cambridge, who must grapple with the hazing of his fellow soldiers, the stirrings of a forbidden sexuality, and the formation of an explosive analytical philosophy that seemed to draw meaning from his endless brushes with death. Much like Tolstoy's The Gospel in Brief, Private Notebooks takes us on a personal journey to discovery as it augments our knowledge of Wittgenstein himself. (shrink)

A sorites argument is a symptom of the vagueness of the predicate with which it is constructed. A vague predicate admits of at least one dimension of variation (and typically more than one) in its intended range along which we are at a loss when to say the predicate ceases to apply, though we start out confident that it does. It is this feature of them that the sorites arguments exploit. Exactly how is part of the subject of this paper. (...) The majority of philosophers writing on vagueness take it to be a kind of semantic phenomenon. If we are right, they are correct in this assumption, which is surely the default position, but they have not so far provided a satisfactory account of the implications of this or a satisfactory diagnosis of the sorites arguments. Other philosophers have urged more exotic responses, which range from the view that the fault lies not in our language, but in the world, which they propose to be populated with vague objects which our semantics precisely reflects, to the view that the world and language are both perfectly in order, but that the fault lies with our knowledge of the properties of the words we use (epistemicism). In contrast to the exotica to which some philosophers have found themselves driven in an attempt to respond to the sorites puzzles, we undertake a defense of the commonsense view that vague terms are semantically vague. Our strategy is to take fresh look at the phenomenon of vagueness. Rather than attempting to adjudicate between different extant theories, we begin with certain pre-theoretic intuitions about vague terms, and a default position on classical logic. The aim is to see whether (i) a natural story can be told which will explain the vagueness phenomenon and the puzzling nature of soritical arguments, and, in the course of this, to see whether (ii) there arises any compelling pressure to give up the natural stance. We conclude that there is a simple and natural story to be told, and we tell it, and that there is no good reason to abandon our intuitively compelling starting point. The importance of the strategy lies in its dialectical structure. Not all positions on vagueness are on a par. Some are so incredible that even their defenders think of them as positions of last resort, positions to which we must be driven by the power of philosophical argument. We aim to show that there is no pressure to adopt these incredible positions, obviating the need to respond to them directly. If we are right, semantic vagueness is neither surprising, nor threatening. It provides no reason to suppose that the logic of natural languages is not classical or to give up any independently plausible principle of bivalence. Properly understood, it provides us with a satisfying diagnosis of the sorites argumentation. It would be rash to claim to have any completely novel view about a topic so well worked as vagueness. But we believe that the subject, though ancient, still retains its power to inform and challenge us. In particular, we will argue that taking seriously the central phenomenon of predicate vagueness—the “boundarylessness” of vague predicates—on the commonsense assumption that vagueness is semantic, leads ineluctably to the view that no sentences containing vague expressions (henceforth ‘vague sentences’) are truth-evaluable. This runs counter to much of the literature on vagueness, which commonly assumes that, though some applications of vague predicates to objects fail to be truth-evaluable, in clear positive and negative cases vague sentences are unproblematically true or false. It is clarity on this, and related points, that removes the puzzles associated with vagueness, and helps us to a satisfying diagnosis of why the sorites arguments both seem compelling and yet so obviously a bit of trickery. We give a proof that semantically vague predicates neither apply nor fail-to-apply to anything, and that consequently it is a mistake to diagnose sorites arguments, as is commonly done, by attempting to locate in them a false premise. Sorites arguments are not sound, but not unsound either. We offer an explanation of their appeal, and defend our position against a variety of worries that might arise about it. The plan of the paper is as follows. We first introduce an important distinction in terms of which we characterize what has gone wrong with vague predicates. We characterize what we believe to be our natural starting point in thinking about the phenomenon of vagueness, from which only a powerful argument should move us, and then trace out the consequences of accepting this starting point. We consider the charge that among the consequences of semantic vagueness are that we must give up classical logic and the principle of bivalence, which has figured prominently in arguments for epistemicism. We argue there are no such consequences of our view: neither the view that the logic of natural languages is classical, nor any plausible principle of bivalence, need be given up. Next, we offer a diagnosis of what has gone wrong in sorites arguments on the basis of our account. We then present an argument to show that our account must be accepted on pain of embracing (in one way or another) the epistemic view of “vagueness”, i.e., of denying that there are any semantically vague terms at all. Next, we discuss some worries that may arise about the intelligibility of our linguistic practices if our account is correct. We argue none of these worries should force us from our intuitive starting point. Finally, we cast a quick glance at other forms of semantic incompleteness. (shrink)

Die Frage, ob «systematische» Philosophie heute noch möglich ist, wird in der Gegenwartsphilosophie kontrovers diskutiert. Sie ist eng verknüpft mit dem Thema «Vernunft und Wirklichkeit».

This article begins by distinguishing force and mood. Then it lays out desiderata on a successful account. It sketches as background the program of truth-theoretic semantics. Next, it surveys assimilation approaches and argues that they are inadequate. Then it shows how the fulfillment-conditional approach can be applied to imperatives, interrogatives, molecular sentences containing them, and quantification into mood markers. Next, it considers briefly the recent set of propositions approach to the semantics of interrogatives and exclamatives. Finally, it shows how to (...) integrate exclamatives and optatives into a framework similar to the fulfillment approach. (shrink)

This article addresses ontological negotiations in the Global South through three case studies of community-based research in Brazil and Ghana. We argue that ontological perspectives of Indigenous people and local communities require an ontological pluralism that recognizes both the plurality of representational tools and of ways of being in the world. Locating these two readings of ontological pluralism in the politics of the Global South, the article highlights a wider dynamic from ontological paternalism to ontological diversity to ontological decolonization. We (...) conclude by arguing that this dynamic provides important lessons for the state for social ontology in academic philosophy and for the design of politically reflexive development interventions.

Ludwig deals with the relations between language, thought, and rationality, and, especially, the role and status of assumptions about rationality in interpreting another’s speech and assigning contents to her psychological attitudes—her beliefs, desires, intentions, and so on. The chapter is organized around three questions: What is the relation between rationality and thought? What is the relation between rationality and language? What is the relation between thought and language? Ludwig argues that some large degree of rationality is required for (...) thought and consequently that same degree of rationality at least is required for language since language requires thought. Thought, however, does not require language. In answering questions and, Ludwig gives particular attention to Davidson’s arguments for the Principle of Charity, according to which it is constitutive of speakers that they are largely rational and largely right about the world, and to Davidson’s arguments for the thesis that without the power of speech we lack the power of thought.

In light of Jewish tradition and the metaphysics of time, we argue that God can and will change the past. The argument makes for a new answer to the problem of evil and a new theory of atonement.

How are we able to perceive the world veridically? If we ask this question as a part of the scientific investigation of perception, then we are not asking for a transcendental guarantee that our perceptions are by and large veridical; we presuppose that they are. Unless we assumed that we perceived the world for the most part veridically, we would not be in a position to investigate our perceptual abilities empirically. We are interested, then, not in how it is possible (...) in general for us to perceive the world veridically, but instead in what the relation is between our environment and its properties, of which we have knowledge, on the one hand, and our perceptual mechanisms, on the other, that results in very many, even most of our perceptions being veridical in everyday life.

Is pragmatism, as focused on a future considered producible by our finite actions, ill equipped to analyze religion (or “Erlösungswissen”, as Max Scheler said); is it unable, as Stanley Cavell writes, to sufficiently explore “skepticism” and negativity? This paper argues that William James succeeds in pragmatically re-thematizing “Erlösungswissen”, and that Josiah Royce—who develops a post-pragmatic, pragmaticist concept of; religion—carefully re-investigates “negativity”, in a Peirce-inspired mode, by focusing on the “mission of sorrow”.

This chapter argues that in cases in which a (non-institutional) group is collectively causally responsible and collectively morally responsible for some harm which is either (i) brought about intentionally or (ii) foreseen as the side effect of something brought about intentionally or (iii) unforeseen but a nonaggregative harm, each member of the group is equally and as fully responsible for the harm as if he or she had done it alone.
