Metaphysicians often claim that some metaphysical theory should (or shouldn’t) be believed because it exhibits (or fails to exhibit) theoretical virtues such as simplicity. Metaphysicians also sometimes claim that the legitimacy of these sorts of appeals to theoretical virtues are vindicated by the similar appeals to theoretical virtues which scientists make in scientific theory choice. One objection to this methodological move is to claim that the metaphysician misdescribes the role that theoretical virtues play within science. In this paper I defend (...) the metaphysician’s use of theoretical virtues against this objection. (shrink)

In the debate over the existence of composite objects, it is sometimes suggested that perceptual evidence justifies belief in composite objects. But it is almost never suggested that we are perceptually justified in believing in composite objects on the basis of the fact that the phenomenology of our perceptual experiences enables us to discriminate between situations where there are composite objects and situations where there are merely simples arranged composite object-wise. But while the thought that the phenomenology of our perceptual (...) experiences cannot enable us to discriminate between situations where there are composite objects and situations where there are merely simples arranged composite object-wise is commonly taken for granted, it requires some defence, both in light of its importance in shaping the debate and in light of its recently coming under attack by a prominent philosopher of perception. In this paper, I offer such a defence. (shrink)

What is a number? Using material from Wittgenstein’s 1930s lectures, I argue that this question expresses a disorientation best overcome by recollecting rules that govern the number words. Why do we have the rules we do? We may be persuaded to adopt one rule rather than another by experience, when experiment shows it to be the more convenient way; we may also be persuaded by the “experience” of a new aspect. Mathematics is a “motley of techniques” for doing certain things; (...) religion is a certain spirit meant to pervade everything we do. An important likeness is that in both instruction is essentially grammatical. (shrink)

Many say that ontological disputes are defective because they are unimportant or without substance. In this paper, we defend ontological disputes from the charge, with a special focus on disputes over the existence of composite objects. Disputes over the existence of composite objects, we argue, have a number of substantive implications across a variety of topics in metaphysics, science, philosophical theology, philosophy of mind, and ethics. Since the disputes over the existence of composite objects have these substantive implications, they are (...) themselves substantive. (shrink)

Metaphysicians frequently appeal to the idea that theoretical simplicity is truth conducive in metaphysics, in the sense that, all other things being equal, simpler metaphysical theories are more likely to be true. In this paper I defend the notion that theoretical simplicity is truth conducive in metaphysics, against several recent objections. I do not give any direct arguments for the thesis that simplicity is truth conducive in metaphysics, since I am aware of no such arguments. I do argue, however, that (...) there is no special problem with the notion that simplicity is truth conducive in metaphysics. More specifically, I argue that if you accept the idea that simplicity is truth conducive in science, then it would be objectionably arbitrary to reject the idea that simplicity is truth conducive in metaphysics.

Kant prit pour pivot de la révolution copernicienne l'immutabilité d'une table qui portait toute l'autorité du classicisme et révélait les opérations secrètes d'un sensus communis logicus. La logique n'avait pas d'histoire. Après la rupture introduite par la logique mathématique et pour la conjurer, on s'est intéressé à son histoire comme présentant autant de variétés d'une même forme. Mais la forme, terme homonyme entre l'eidos platonicien et la syntaxe moderne, gardait l'écorce sans le fruit, oubliant que l'héritage grec avait fructifié ailleurs, (...) dans les arts et dans les sciences et vivait précisément de ses métamorphoses. Le projet de Platon, accompli par le stoïcisme, donne la mesure de l'héritage athénien. L'épisode ouvert par Frege laissait un tout autre avenir que de choisir entre la formalisation ou le silence. Car la logique mathématique, liée à l'histoire de l'algèbre et de la calculabilité, ménageait la place pour une activité philosophique délivrée à son tour des opérations obscures du sens commun et consciente de ses symbolismes. Ce qui redonne sens aux réformes de l'entendement, opération philosophique essentielle et constante, contre les méthodes supposées régir toutes les manières de la connaissance. Cette autre histoire se trame de Port-Royal, à d'Alembert, Wittgenstein, Cavaillès et Merleau-Ponty. La connaissance s'y trouve servie par la diversité de ses supports, y compris styles et syntaxes, tous inscrits sur le palimpseste des opérations inconscientes qui précèdent toute épistémologie.

In “The logic of deep disagreements” (Informal Logic, 1985), Robert Fogelin claimed that there is a kind of disagreement – deep disagreement – which is, by its very nature, impervious to rational resolution. He further claimed that these two views are attributable to Wittgenstein. Following an exposition and discussion of that claim, we review and draw some lessons from existing responses in the literature to Fogelin’s claims. In the final two sections (6 and 7) we explore the role reason can, (...) and sometimes does, play in the resolution of deep disagreements. In doing this we discuss a series of cases, mainly drawn from Wittgenstein, which we take to illustrate the resolution of deep disagreements through the use of what we call “rational persuasion.” We conclude that, while the role of argumentation in “normal” versus “deep” disagreements is characteristically different, it plays a crucial role in the resolution of both.

Mereological nihilism (henceforth just "nihilism") is the thesis that composition never occurs. Nihilism has often been defended on the basis of its theoretical simplicity, including its ontological simplicity and its ideological simplicity (roughly, nihilism's ability to do without primitive mereological predicates). In this paper I defend nihilism on the basis of the theoretical unification conferred by nihilism, which is, roughly, nihilism's capacity to allow us to take fewer phenomena as brute and inexplicable. This represents a respect in which nihilism enjoys (...) greater theoretical simplicity than its rivals which has not yet been explored, and which is immune to many of the objections which have been leveled against previous arguments for nihilism from nihilism's theoretical simplicity. Composition as identity might be thought to confer a similar degree of theoretical unification as nihilism. I end the paper by arguing that this is not the case. (shrink)

Despite an intractable judiciary, there is widespread consensus within the legal academy that jury nullification is compatible with the rule of law. This proposition is most strongly tested by where a jury nullifies simply because it disagrees with the law itself. While some substantive nullifications can comport with the rule of law, most commentatorsjustice,vely undifferentiated view of a morality (even though jurisdictional and vicinage morality can diverge). In doing so, a healthy vision of antityrannical nullifications is presented, but this leaves (...) out many problematic cases. Once these errors are rectified, a more nuanced picture emerges, and it becomes apparent that localism will often disrupt the congruence feature of the rule of law. (shrink)

While democracy is derided for a variety of reasons in Plato’s thought, his most damning critique of that regime type does not involve an observation about democracy qua democracy, but of the transition that it so easily engenders: the decline to tyranny. Regimes are composed of individuals and groups, though, and Plato is anxious to ascribe culpability for the degradation. Two actors are the primary focus of his analysis — the political leaders and the demos. At times he emphasizes the (...) puissance of the demos, but in other passages he suggests it is the leaders who are most authoritative. This paper discusses these apparently contradictory passages, and works towards a reconciliation. It argues that neither is assigned sole culpability, as both work in complex synrgy, and that the underlying cause of the decline—and the motivator behind both actors — is not simply freedom, but greed for material wealth.

Segue abaixo a tradução do alemão da seção dedicada ao cinismo presente nas Lições Sobre a História da Filosofia de Georg Wilhelm Friedrich Hegel (1770-1831). Na seção em questão, o filósofo alemão aborda não somente a história da escola cínica, mas também seus princípios, suas influências e a importância que esse movimento teve para o pensamento filosófico posterior – sobretudo para o estoicismo.

Mereological nihilism is the thesis that composite objects—objects with proper parts—do not exist. Nihilists generally paraphrase talk of composite objects F into talk of there being “xs arranged F-wise” . Recently several philosophers have argued that nihilism is defective insofar as nihilists are either unable to say what they mean by such phrases as “there are xs arranged F-wise,” or that nihilists are unable to employ such phrases without incurring significant costs, perhaps even undermining one of the chief motivations for (...) nihilism. In this paper I defend nihilism against these objections. A key theme of the paper is this: if nihilists need to employ such phrases as “there are xs arranged F-wise,” non-nihilists will need to do so as well. Accordingly, any costs incurred by the nihilist when she employs such phrases will be shared by everyone else. What’s more, such phrases are intelligible when employed by the nihilist, as well as when they are employed by the non-nihilist, insofar as analyses of such phrases will not essentially involve mereological concepts incompatible with nihilism.

Mereological nihilists hold that composition never occurs, so that nothing is ever a proper part of anything else. Substance dualists generally hold that we are each identical with an immaterial soul. In this paper, I argue that every popular objection to substance dualism has a parallel objection to composition. This thesis has some interesting implications. First, many of those who reject composition, but accept substance dualism, or who reject substance dualism and accept composition, have some explaining to do. Secondly, one (...) popular objection to mereological nihilism, one which contends that mereological nihilism is objectionable insofar as it is incompatible with the existence of people, is untenable.

Mereological nihilism is the thesis that composition never occurs. Some philosophers have thought that science gives us compelling evidence against nihilism. In this article I respond to this concern. An initial challenge for nihilism stems from the fact that composition is such a ubiquitous feature of scientific theories. In response I motivate a restricted form of scientific anti-realism with respect to those components of scientific theories which make reference to composition. A second scientifically based worry for nihilism is that certain (...) specific scientific phenomena might require ineliminable quantification over composite objects. I address these concerns, and argue that there seem to be nihilist-friendly construals of the scientific phenomena in question. (shrink)

Mereological nihilism is the thesis that composition never occurs. Sider has defended nihilism on the basis of its relative ideological simplicity. In this paper I develop the argument from ideological simplicity, and defend it from some recent objections. Along the way I discuss the best way to formulate nihilism, what it means for a theory to exhibit lesser or greater degrees of ideological simplicity, the relationship between the parthood relation and the identity relation, and the notion that we should judge (...) the ideological simplicity of competing theories on the basis of the kinds of ideological commitments required by those theories.

The concept of an operator is used in a variety of practical and theoretical areas. Operators, as both conceptual and physical entities, are found throughout the world as subsystems in nature, the human mind, and the manmade world. Operators, and what they operate, i.e., their substrates, targets, or operands, have a wide variety of forms, functions, and properties. Operators have explicit philosophical significance. On the one hand, they represent important ontological issues of reality. On the other hand, epistemological operators form (...) the basic mechanism of cognition. At the same time, there is no unified theory of the nature and functions of operators. In this work, we elaborate a detailed analysis of operators, which range from the most abstract formal structures and symbols in mathematics and logic to real entities, human and machine, and are responsible for effecting changes at both the individual and collective human levels. Our goal is to find what is common in physical objects called operators and abstract mathematical structures, with the name operator providing foundations for building a unified but flexible theory of operators. The paper concludes with some reflections on functionalism and other philosophical aspects of the ‘operation’ of operators. (shrink)

Some facts ground other facts. Some fact is fundamental iff there are no other facts which partially or fully ground that fact. According to metaphysical foundationalism, every non-fundamental fact is fully grounded by some fundamental fact(s). In this paper I examine and defend some neglected considerations which might be made in favor of metaphysical foundationalism. Building off of work by Ross Cameron, I suggest that foundationalist theories are more unified than, and so in one important respect simpler than, non-foundationalist theories, (...) insofar as foundationalist theories allow us to derive all non-fundamental facts from some fundamental fact(s). Non-foundationalist theories can enjoy a similar sort of theoretical unification only by taking on objectionable metaphysical laws. (shrink)

Kris McDaniel has recently proposed an interpretation of the distinction between conventional truth and ultimate truth, as that distinction is made within Abhidharma metaphysics. According to McDaniel's proposal, the distinction between conventional truth and ultimate truth is closely connected with a similar distinction between conventional existence and ultimate existence. What is more, the distinction between conventional existence and ultimate existence should be interpreted along ontological pluralist lines: the difference between things that ultimately exist and things that merely conventionally exist amounts (...) to a difference in the modes of being enjoyed by the things in question.One...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Historiography of Philosophy by Michael FredeClaude PanaccioMichael Frede. The Historiography of Philosophy. Edited by Katerina Ierodiakonou, with a postface by Jonathan Barnes. Oxford: Oxford University Press, 2022. Pp. 256. Hardback, $80.00.From the 1970s until his tragic death in 2007, Michael Frede was one of the most prominent scholars in ancient Greek philosophy, with landmark contributions to the study of Aristotle and of Hellenistic thought in particular. This (...) volume contains his theoretical reflections on the work of historians of philosophy. The main part of the book reproduces with minor corrections the previously unpublished text of the Nellie Wallace Lectures that Frede gave in 1989–90 in Oxford (1–135). Then come three papers that he published on pretty much the same topic between 1987 and 1992 (137–88). Jonathan Barnes's postface, finally, launches an exciting discussion of Frede's proposals by raising a number of questions and critical remarks about them (189–230).Frede's main claim throughout the book is that there is, and should be, a distinctively historical approach to the history of philosophy that has not yet been sufficiently recognized as such in the academic world. This is not to say that he considers more philosophical approaches to be illegitimate. His point is that we have to be clear about the distinction and what it involves in terms of requirements and methods. What Frede calls the "historical history of philosophy" is thus contrasted by him with two varieties of philosophical approaches. One of them he identifies as the "philosophical history of philosophy." It consists in retrospectively studying the past of philosophy as a kind of maturation toward some more recent doctrinal stage, as Aristotle or Hegel saliently did with their respective predecessors. Frede takes this to be "a perfectly intelligible and legitimate, though perhaps not particularly interesting or fruitful, enterprise" (41). Most of the time, he thinks, it would be led by its own philosophical presuppositions to be too selective and to provide a badly distorted picture of past philosophy.Frede is much more sympathetic to the other philosophical approach to the history of philosophy he acknowledges, the one he calls "doxography." This is the study of past philosophers with the aim of finding something of interest in them for ongoing philosophical discussions—a familiar practice, indeed, in the philosophical discipline as we know it. There is an inevitable amount of anachronism in such endeavors, according to Frede, insofar as the commentators will have to reformulate the old views in contemporary terms to a certain extent and to look at them in connection with the questions that are currently debated in the field. But Frede deems this kind of anachronism acceptable as long as sufficient care is taken to correctly identify the views of the past we are interested in and to report them in the best available way. He strongly insists, however, that there are inherent risks of distortion in this approach. This might not be a problem if we are prepared to deal, as philosophers, with views that were not exactly those of the past; but we then run the risk of leaving out something of great philosophical interest, even to us, since "as a rule the philosopher subjected to doxographical treatment was a much better philosopher than the doxographer" (34). If we turn to the past for philosophical inspiration, we should also do it seriously, and this presupposes a historical study of past authors that is pursued for its own sake. [End Page 317]The latter is what Frede is really interested in, and he wants this historical approach to be "as independent as possible from philosophy and not just an ancilla to philosophy" (60). Its practitioners must have a strong philosophical training, of course, in order to understand the views they study and the arguments that were adduced in support of them, but Frede insists that they nevertheless are historians first and foremost: they strive to provide a correct account of "the actual, historical evolution of these views and positions" (14) and of how new doctrines actually grew out of previous ones given the historical context. Insofar as this is what they are doing, historians of... (shrink)

It is sometimes supposed that, in principle, we cannot offer an explanation for why there is something rather than nothing. I argue that this supposition is a mistake, and stems from a needlessly myopic conception of the form explanations can legitimately take. After making this more general point, I proceed to offer a speculative suggestion regarding one sort of explanation which can in principle serve as an answer to the question “why is there something rather than nothing?” The suggestion is (...) that there may be something rather than nothing in virtue of the truth of certain sorts of subjunctive conditionals.

Stoffregen & Bardy's target article is based on the assumption that our senses' ultimate purpose is to provide us with perfect information about the outside world. We argue that it is often more important that information be available quickly than that it be perfect. Consequently our nervous system processes different aspects of information about our surrounding as separately as possible. The separation is not between the senses, but between separate aspects of our surrounding. This results in inconsistencies between judgments: sometimes (...) because different frames of reference are used. Such inconsistencies are fundamental to the way the information is picked up, however, and hence cannot be avoided with clearer instructions to the subjects. (shrink)

ArgumentAfter having measured the velocity of the nervous impulse in the 1850s, Helmholtz began doing research on the temporal dimensions of visual perception. Experiments dealing with the velocity of propagation in nerves were carried out occasionally for some fifteen years until their final publication in 1871. Although the temporal dimension of perception seems to have interested Helmholtz less than problems of geometry and space, his experiments on the time of perception were technically rather subtle and seminal, especially compared with experiments (...) performed by his contemporaries, such as Sigmund Exner, William James, Rudolf Hermann Lotze, Ernst Mach, Wilhelm Volkmann, and Wilhelm Wundt. Helmholtz’s conception of the temporal aspects of perception reflects the continuity that holds between psychophysiological research and the Kantian philosophical background. (shrink)

In the latest years of the 6th/12th century, two chains of affiliation of a distinctive kind make their appearance in the Muslim world, in the East on one hand, and in the West on the other: the first is referred to in the sources as silsilat al-muṣāfaḥa, the second as silsilat al-mushābaka. These ‘chains’, mentioned mostly in works pertaining to the genre of prosopographic literature in the largest sense, experienced a broad and rapid expansion throughout the dār al-islām. They are (...) linked to a specific ritual aimed at perpetuating, across generations, a physical contact with the Prophet. Widespread among the ʿulamāʾ, they become conflated with the musalsalāt ḥadīths, or ‘chained traditions’, during the Ottoman era. (shrink)
