This paper examines two puzzles of indeterminacy. The first puzzle concerns the hypothesis that there is a unified phenomenon of indeterminacy. How are we to reconcile this with the apparent diversity of reactions that indeterminacy prompts? The second puzzle focuses narrowly on borderline cases of vague predicates. How are we to account for the lack of theoretical consensus about what the proper reaction to borderline cases is? I suggest (building on work by Maudlin) that the characteristic feature of indeterminacy is (...) alethic normative silence, and use this to explain both plurality and lack of consensus. (shrink)

We discuss arguments against the thesis that the world itself can be vague. The first section of the paper distinguishes dialectically effective from ineffective arguments against metaphysical vagueness. The second section constructs an argument against metaphysical vagueness that promises to be of the dialectically effective sort: an argument against objects with vague parts. Firstly, cases of vague parthood commit one to cases of vague identity. But we argue that Evans' famous argument against will not on its own enable one to (...) complete the reductio in the present context. We provide a metaphysical premise that would complete the reductio, but note that it seems deniable. We conclude by drawing general morals from our case study. (shrink)

Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.

In this brief comment, I aim to engage with Sandy Goldberg’s fruitful discussion of the doctrine of epistemic partiality in friendship (EPF), as it appears in his new book Conversational Pressure: Normativity in Speech Exchanges (2020), and to explore a seemly small distinction that I think could complicate things for the way Goldberg sees the pressures that are put on us when we are confronted with speech acts that come from or relate to friends of ours. If my distinction is (...) shown to be successful, I believe it will impact the efficacy of Goldberg’s response to EPF. My main argument focuses on the way Goldberg argues against EPF and the tension it supposedly creates with the demands of epistemic rationality. I believe that Goldberg’s argument fails to capture an important distinction between our epistemic behaviors in the face of a friend’s say-so and our epistemic behaviors when we encounter third-party reports about a friend. I’ll argue that the route from the valuing of friendship to the epistemic reasons in support of differential doxastic outcomes when our friends are involved is not satisfactory, given that it involves what I see to be an unauthorized move from our desire to preserve a friendship to a differential doxastic reaction when someone reports negatively about our friends.

Um alinhamento responsável à alguma versão do naturalismo filosófico requer a articulação explicita e cuidadosa de um argumento em sua defesa. Em quatro passos, o texto que segue abaixo expande e examina a validade de um argumento que é frequentemente rascunhado em favor do naturalismo. Como veremos, contudo, a versão do naturalismo que esse argumento nos permite é um pouco diferente dos naturalismos filosóficos mais populares.

The orthodox presentation of quantum theory often includes statements on state preparation and measurements without mentioning how these processes can be achieved. The often quoted projection postulate is regarded by many as problematical. This paper presents a systematic framework for state preparation and measurement. Within the existing Hilbert space formulation of quantum mechanics for spinless particles we show that it is possible (1)to prepare an arbitrary state and (2)to reduce all quantum measurements to local position measurements in an asymptotic way (...) by unitary evolution processes without recourse to the projection postulate. A generalization to spin-1/2particles is also given. The theory presented provides a general mathematical and theoretical foundation for many practical schemes for state preparation and measurement.

A type of first-order analogues of ptykes, namely ‘ptykoids’, are introduced, and bounds are found for the ptykoids of level 1 and 2 which can be proved to be ptykoids in Peano arithmetic. This gives rise toΠ 3 0 andΠ 4 0 independence results.

The dominant feature of eighteenth-century aesthetic is the inquiry and discussion concerning the theory of “taste.” There is material or bibliographical evidence of this in the rapid sequence of treatises, essays, inquiries, observations, and controversies on this subject, extending from the close of the seventeenth to the last years of the eighteenth century, and bearing the names, in France, of Dacier, Bellegarde, Bouhours, Rollin, Seran de la Tour, Trublet, Formey, Bitaubé, Marmontel, and, still more eminent, of Montesquieu, Voltaire, d’Alembert; in (...) England, of Addison, Hume, Gerard, Home, Burke, Priestley, Blair, Beattie, Percival, Reid, Alison; in Italy, of Muratori, Calepio, Pagano, Corniani; in Germany, of Thomasius, J. U. König, Bodmer, A. von Schlegel, Wegelin, Heyne, Herz, Eberhard, J. C. König, and, by German influence in Hungary, Szardahely; and, greatest of all, Immanuel Kant, whoseCritique of Judgmentconsists in the main of a critique of the aesthetic judgment of taste. (shrink)

Na de Tweede Wereldoorlog heerstte in Duitsland nog lange tijd zwijgen over de misdaden van het Nazi-bewind. Pas in de Historikerstreit van 1985-1986 kwam het onverwerkte verleden in de openbaarheid.. Enerzijds werden de Duitse oorlogsmisdaden vergeleken met die van Stalin en Pol Pot, anderzijds werd de holocaust afgeschilderd als een soort natuurramp, die zich buiten de historische realiteit had afgespeeld. Over dit dilemma is het laatste woord nog niet gezegd.

§ 1. Of all the subjects which for well over two thousand years have remained the more or less constant topics of philosophical discussion, I can think of none which has not at some time by some philosopher been dismissed as a nonentity or an illusion. The history of philosophy seems to show that we cannot begin fairly to estimate the nature of any element in the universe until we have steadily contemplated a universe from which that element has been (...) hypothetically eliminated.

For a century or so after his death Hegel's system excited, if not wider diversity of interpretation and more bitter controversy, then certainly more bewilderment, than had ever before befogged the battlefields of speculative thought. A few fervent disciples maintained that their master had achieved a system substantially if not in all detail final and complete, a philosophy destined to set at rest forever all serious philosophic doubt. Others agreed that this claim to finality was inherent in the system, but (...) mocked openly, proclaiming Hegel an arrogant megalomaniac. (shrink)

§ 22. Logic for Bradley, who follows the Kantian tradition, means primarily a theory of judgment. His definition of judgment is made so wide that it really covers inference as well. The “reference of an ideal content to reality,” as soon as that content is taken as complex and as not atomic, covers inference denned as ideal self-development of an object. Though the definition of judgment has a subjective flavour due to the way in which Bradley finds it necessary to (...) distinguish it from psychical fact, he does not mean to imply that it is any less objective than inference. We learn from the second edition of the Logic that judgment so far as it is mediated is inference, and that mere unmediated judgment is nothing. Judgment, he says, though distinct from inference in form, is everywhere inference really though not explicitly; and almost the first words of the Terminal Essay on Judgment are: “Whatever else and however much else an inference may be, an inference still is a judgment.”.

The evolution of internation relationships is studied by means of a mathematical model based on a popular rule of triadic interaction: the friend of my friend is my friend, the friend of my enemy is my enemy, the enemy of my enemy is my friend, the enemy of my friend is my enemy. The rule is shown to lead to the formation and preservation of unipolar and bipolar configurations of nations, with the strengths of relationships, both friendly and conflictual, intensifying (...) through time. These results confirm speculations originally made in static, graph theoretic studies of the balancing of relationships within individuals, small groups and systems of nations. (shrink)

This article addressed the issue of how the author of the Gospel according to John portrayed dissent, in particular, how the author had his protagonists respond to the experience of rejection by those typically designated as ‘the Jews’. Research thus far has usually focused on the identity of the dissenters but rarely on the way dissent was handled. This article’s aim was to examine the range of responses to dissent. It employed a sequential reading of the text to identify the (...) various responses and then brought these findings into comparison with the way dissent was handled in related documents of the time, Matthew and Hebrews. It found that responses included not only argument and blame, including threat of divine wrath but also, beyond these, ad hominem allegations that those who dissent were inherently bad or beholden to the devil or had not been predestined or chosen by God to respond. Such categories were, however, not absolute, because the author assumed that people could choose to respond positively and so move from one apparently fixed and predetermined category to another. They served a rhetorical function. A further ploy was to reduce Israel’s tradition to witness and foreshadowing within the tension of asserting both continuity and discontinuity. Contribution: The article concluded that such strategies served in part to comfort and reassure hearers engaged in the process of grief at rejection. As such they warranted critical reflection.

On what grounds will the rational man become a Christian? It is often assumed by many, especially non-Christians, that he will become a Christian if and only if he judges that the evidence available to him shows that it is more likely than not that the Christian theological system is true, that, in mathematical terms, on the evidence available to him, the probability of its truth is greater than half. It is the purpose of this paper to investigate whether or (...) not this is a necessary and sufficient condition for the rational man to adopt Christianity. (shrink)

An alleged moral right to informational privacy assumes that we should have control over information about ourselves. What is the philosophical justification for this control? I think that one prevalent answer to this question—an answer that has to do with the justification of negative rights generally—will not do.
