The rise of experimental philosophy has placed metaphilosophical questions, particularly those concerning concepts, at the center of philosophical attention. X-phi offers empirically rigorous methods for identifying conceptual content, but what exactly it contributes towards evaluating conceptual content remains unclear. We show how x-phi complements Rudolf Carnap’s underappreciated methodology for concept determination, explication. This clarifies and extends x-phi’s positive philosophical import, and also exhibits explication’s broad appeal. But there is a potential problem: Carnap’s account of explication was limited to empirical and (...) logical concepts, but many concepts of interest to philosophers are essentially normative. With formal epistemology as a case study, we show how x-phi assisted explication can apply to normative domains. (shrink)

There is good reason to believe that scientific realism requires a commitment to the objective modal structure of the physical world. Causality, equilibrium, laws of nature, and probability all feature prominently in scientific theory and explanation, and each one is a modal notion. If we are committed to the content of our best scientific theories, we must accept the modal nature of the physical world. But what does the scientific realist’s commitment to physical modality require? We consider whether scientific realism (...) is compatible with Humeanism about the laws of nature, and we conclude that it is not. We specifically identify three major problems for the best-systems account of lawhood: its central concept of strength cannot be formulated non-circularly, it cannot offer a satisfactory account of the laws of the special sciences, and it can offer no explanation of the success of inductive inference. In addition, Humeanism fails to be naturalistically motivated. For these reasons, we conclude that the scientific realist must embrace natural necessity. (shrink)

Eternalists believe that there is no ontological difference between the past, present and future. Thus, a challenge arises: in virtue of what does time have a direction? Some eternalists, Oaklander and Tegtmeier ) argue that the direction of time is primitive. A natural response to positing primitive directionality is the suspicion that said posit is too mysterious to do any explanatory work. The aim of this paper is to relieve primitive directionality of some of its mystery by offering a novel (...) way to understand the phenomenon in terms of the recently popularised notion of grounding.

Although critics often argue that the new atheists are arrogant, dogmatic, closed-minded and so on, there is currently no philosophical analysis of this complaint - which I will call 'the vice charge' - and no assessment of whether it is merely a rhetorical aside or a substantive objection in its own right. This Chapter therefore uses the resources of virtue epistemology to articulate this ' vice charge' and to argue that critics are right to imply that new atheism is intrinsically (...) epistemically vicious, and it ends with some remarks about the rationality of allowing such intrinsically vicious doctrines to feature within public debate about important matters concerning science, religion, and politics.

It is very well known that from the late-1960s onwards Feyerabend began to radically challenge some deeply-held ideas about the history and methodology of the sciences. It is equally well known that, from around the same period, he also began to radically challenge wider claims about the value and place of the sciences within modern societies, for instance by calling for the separation of science and the state and by questioning the idea that the sciences served to liberate and ameliorate (...) human societies. But what is less known is how, if at all, these two sets of challenges were connected, and why Feyerabend felt it important to raise them at all. In this chapter, my aim is to explore these issues by considering why Feyerabend used radical strategies to challenge the authority of science, and what purpose, if any, they were supposed to serve. Why, for instance, did Feyerabend defend alternative medicine, psychical abilities, astrology, magic and witchcraft and why did he argue that ‘Western science’ is complicit in environmental destruction, intellectual imperialism, social oppression, and spiritual destitution. Located in their historical and political context, such defences and arguments seem peculiar, not least because science was recognised not only as a central site of the intellectual and ideological competition between the West and the Soviet Union, but also because Western victory in that site was considered inevitable. What, then, did Feyerabend think he was trying to achieve by raising radical challenges to a central component of the cultural and intellectual prestige of the Western world grounded in appeals to practices and traditions which most would regard as eccentric at best and absurd at worst? My suggestion is that Feyerabend was making a subtler point than one might suppose. For the purpose of these radical challenges was to determine if the members of Western societies would in fact honour the epistemic standards – of tolerance, critical enquiry – which were identified as being characteristic of science and definitive of the social and political values of Western liberal democracy. I suggest that Feyerabend was trying to demonstrate that scientists were, too often, guilty of the same intolerant and dogmatic attitudes which were, according to prevailing propaganda, the property of illiberal totalitarian societies. Science does not reflect the superior epistemic and political values of Western societies but are, in fact, reflective of the same vices ascribed to the Soviet Union. If that is the case, then the sciences are not symbols of our epistemic and political values, but quite the reverse, hence Feyerabend’s talk of the ‘dogmatic’, ‘totalitarian’, ‘ratiofascist’ nature of modern science. But there is a positive upshot to Feyerabend’s challenge. For even if the sciences do not yet reflect the epistemic and political values of liberal democratic Western societies, they might yet be reformed so that they are. And there is a parallel between Feyerabend’s strategy and that of many of the other radicals of the time – student activists, environmentalists, and pacifists – namely to test the commitment to tolerance and deliberative debate of the establishment by asking it to seriously engage with ideas and convictions opposed to its own. For both science and society can become ‘tyrannical’ through the same means: by exempting themselves from critical scrutiny, by promoting self-serving ‘myths’ about themselves, and by derogating and excluding alternatives, including the ‘outsider’ perspectives they offer. The chapter concludes by suggesting that Feyerabend is distinctive in virtue of his willingness to offer radical criticisms of the authority of science such that it can fulfil its legitimate ideological role – namely, of symbolising and instantiating our core epistemic and political values – such that we can offer a sincere and meaningful answer to Feyerabend’s question ‘what’s so great about science?’.

Theism and its cousins, atheism and agnosticism, are seldom taken to task for logical-epistemological incoherence. This paper provides a condensed proof that not only theism, but atheism and agnosticism as well, are all of them conceptually self-undermining, and for the same reason: All attempt to make use of the concept of “transcendent reality,” which here is shown not only to lack meaning, but to preclude the very possibility of meaning. In doing this, the incoherence of theism, atheism, and agnosticism is (...) secondary to the more general incoherence of any attempts to refer to so-called “transcendent realities.” A recognition of the conceptually fundamental incoherence of theism, atheism, and agnosticism compels our rational assent to a position the author names “paratheism.”.

According to Quine’s indispensability argument, we ought to believe in just those mathematical entities that we quantify over in our best scientific theories. Quine’s criterion of ontological commitment is part of the standard indispensability argument. However, we suggest that a new indispensability argument can be run using Armstrong’s criterion of ontological commitment rather than Quine’s. According to Armstrong’s criterion, ‘to be is to be a truthmaker (or part of one)’. We supplement this criterion with our own brand of metaphysics, 'Aristotelian (...) (...) realism', in order to identify the truthmakers of mathematics. We consider in particular as a case study the indispensability to physics of real analysis (the theory of the real numbers). We conclude that it is possible to run an indispensability argument without Quinean baggage. (shrink)

If people believe that some property is true of all members of a class such as sofas, then they should also believe that the same property is true of all members of a conjunctively defined subset of that class such as uncomfortable handmade sofas. A series of experiments demonstrated a failure to observe this constraint, leading to what is termed the inverse conjunction fallacy. Not only did people often express a belief in the more general statement but not in the (...) more specific, but also when they accepted both beliefs, they were inclined to give greater confidence to the more general. It is argued that this effect underlies a number of other demonstrations of fallacious reasoning, particularly in category-based induction. Alternative accounts of the phenomenon are evaluated, and it is concluded that the effect is best interpreted in terms of intensional reasoning [Tversky, A., & Kahneman, D.. Extensional versus intuitive reasoning: the conjunction fallacy in probability judgment. Psychological Review, 90, 293-315.]. (shrink)

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems diachronically irrational. To (...) avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

The central hypothesis of the collaboration between Language and Computing (L&C) and the Institute for Formal Ontology and Medical Information Science (IFOMIS) is that the methodology and conceptual rigor of a philosophically inspired formal ontology greatly benefits application ontologies. To this end r®, L&C’s ontology, which is designed to integrate and reason across various external databases simultaneously, has been submitted to the conceptual demands of IFOMIS’s Basic Formal Ontology (BFO). With this project we aim to move beyond the level of (...) controlled vocabularies to yield an ontology with the ability to support reasoning applications. Our general procedure has been the implementation of a meta-ontological definition space in which the definitions of all the concepts and relations in LinKBase® are standardized in a framework of first-order logic. In this paper we describe how this standardization has already led to an improvement in the LinKBase® structure that allows for a greater degree of internal coherence than ever before possible. We then show the use of this philosophical standardization for the purpose of mapping external databases to one another, using LinKBase® as translation hub, with a greater degree of success than possible hitherto. We demonstrate how this offers a genuine advance over other application ontologies that have not submitted themselves to the demands of philosophical scrutiny. LinKBase® is one of the world’s largest applications-oriented medical domain ontologies, and BFO is one of the world’s first philosophically driven reference ontologies. The collaboration of the two thus initiates a new phase in the quest to solve the so-called “Tower of Babel”. (shrink)

We are perpetually confined within the horizons of our conceptual structure.

In this review essay, I review in detail Abram de Swann's fine new book, The Killing Compartments. The book is a theoretical analysis of the varieties and causes of genocides and other mass asymmetrical killing campaigns. I then suggest several criticisms of his analysis.

THE CASE FOR GOVERNMENT BY ARTIFICIAL INTELLIGENCE. Tired of election madness? The rhetoric of politicians? Their unreliable promises? And less than good government? -/- Until recently, it hasn’t been hard for people to give up control to computers. Not very many people miss the effort and time required to do calculations by hand, to keep track of their finances, or to complete their tax returns manually. But relinquishing direct human control to self-driving cars is expected to be more of a (...) challenge, despite the predicted decrease in vehicle accidents thanks to artificial intelligence that isn’t subject to human distractions and errors of judgment. -/- If turning vehicle control over to artificial intelligence is a challenge, it is a very mild one compared with the idea that we might one day recognize and want to implement the advantages of human government by AI. But, like autonomous vehicle control, government by AI is likely to offer decided benefits. -/- In other publications, the author has studied a variety of widespread human limitations that, throughout human history, have led to much human suffering as well as ecological destruction. For the first time, these psychological and cognitive human shortcomings are taken into account in an essay that makes the case for government by artificial intelligence. (shrink)

In this paper, we show how an internal tension in Wilfrid Sellars’s understanding of truth, as well as an external tension in his account of meaning attribution, can be resolved while adhering to a Sellarsian spirit, by appealing to the particular fictionalist accounts of truth-talk and proposition-talk that we have developed elsewhere.

This review aims to identify (1) sources of knowledge and (2) important themes of the ethical debate related to surgical alteration of facial features in East Asians. This article integrates narrative and systematic review methods. In March 2014, we searched databases including PubMed, Philosopher’s Index, Web of Science, Sociological Abstracts, and Communication Abstracts using key terms “cosmetic surgery,” “ethnic*,” “ethics,” “Asia*,” and “Western*.” The study included all types of papers written in English that discuss the debate on rhinoplasty and blepharoplasty (...) in East Asians. No limit was put on date of publication. Combining both narrative and systematic review methods, a total of 31 articles were critically appraised on their contribution to ethical reflection founded on the debates regarding the surgical alteration of Asian features. Sources of knowledge were drawn from four main disciplines, including the humanities, medicine or surgery, communications, and economics. Focusing on cosmetic surgery perceived as a westernising practice, the key debate themes included authenticity of identity, interpersonal relationships and socio-economic utility in the context of Asian culture. The study shows how cosmetic surgery of ethnic features plays an important role in understanding female identity in the Asian context. Based on the debate themes authenticity of identity, interpersonal relationships, and socio-economic utility, this article argues that identity should be understood as less individualistic and more as relational and transformational in the Asian context. In addition, this article also proposes to consider cosmetic surgery of Asian features as an interplay of cultural imperialism and cultural nationalism, which can both be a source of social pressure to modify one’s appearance.

In the beginning of the 20th century the groundbreaking work of Ramon y Cajal firmly established the neuron doctrine, according to which neurons are the basic structural and functional units of the nervous system. Von Weldeyer coined the term “neuron” in 1891, but the huge leap forward in neuroscience was due to Cajal’s meticulous microscopic observations of brain sections stained with an improved version of Golgi’s la reazione nera (black reaction). The latter improvement of Golgi’s technique made it possible to (...) visualize the arborizations of single neurons that were “colored brownish black even to their finest branchlets, standing out with unsurpassable clarity upon a transparent yellow background. All was sharp as a sketch with Chinese ink”. The high quality of both the visualization of individual nerve cells and the work performed on studying the anatomy of the central nervous system lead Ramon y Cajal to the conclusion that axons output the nervous impulses to the dendrites or the soma of other target neurons.

In this essay, I review in great detail Ian Garden’s outstanding book, The Third Reich’s Celluloid War. Garden begins by discussing propaganda theory and then discusses not just Nazi feature films and documentaries, but television as well. (The Nazis had the earliest TV network). All in all, the regime produced over 1,300 feature films during its time in power. Garden also compares Nazi propaganda films to British and American ones.

In this essay, I look at two films as possible exemplars of the Nietzschean view of egoism. Compulsion is based on the infamous 1924 Leopold and Loeb murder case. In the movie, two arrogant young men—one of whom admires Nietzsche and preaches the (apparently Nietzschean) view that the strong and superior don’t need to follow conventional morality—kill a boy to prove they can outsmart the unter-menschen police. For a different take on what Nietzsche may have had in mind as “the (...) Overman,” I also look at the film The Moon and Sixpence. Here the protagonist isn’t violent or aggressive, but a completely self-absorbed artist, who paints with genius but uses others without feeling any gratitude or friendship, let alone love. (shrink)

In this essay, I take up the question of why so many of the movies made by Hollywood are endless sequels, “prequels,” and remakes of prior blockbuster hits and so many are based on comic books (X-men, Superman, Batman, and so on). I tie the explanation in part to the aforementioned 1950 Supreme Court ruling prohibiting production companies, and in part to broader cultural changes. In particular, I argue that precisely because film producers can no longer make money from the (...) concessions (i.e., the purchases within the theater), but only of the ticket sales, the producers keep producing remakes of known popular movies, rather than make deeply original movies.

In this essay, I review an extraordinary bio flick, Temple Grandin. Temple Grandin is a professor of animal science, and to achieve her distinguished career she had to deal with her autism.

ABSTRACT: Central to both James’s earlier psychology and his later philosophical views was a recurring distinction between percepts and concepts. The distinction evolved and remained fundamental to his thinking throughout his career as he sought to come to grips with its fundamental nature and significance. In this chapter, I focus initially on James’s early attempt to articulate the distinction in his 1885 article “The Function of Cognition.” This will highlight a key problem to which James continued to (...) return throughout his later philosophical work on the nature of our cognition, including in his famous “radical empiricist” metaphysics of “pure experience” around the turn of the century. We shall find that James grappled insightfully but ambivalently with the perceptual and conceptual dimensions of the “knowledge relation” or the “cognitive relation,” as he called it—or what, following Franz Brentano, philosophers would later call our object-directed thought or intentionality more generally. Some philosophers have once again returned to James’s work for crucial insights on this pivotal topic, while others continue to find certain aspects of his account to be problematic. What is beyond dispute is that James’s inquiries in this domain were both innovative and of lasting significance. (shrink)

The logical interpretation of probability, or "objective Bayesianism'' – the theory that (some) probabilities are strictly logical degrees of partial implication – is defended. The main argument against it is that it requires the assignment of prior probabilities, and that any attempt to determine them by symmetry via a "principle of insufficient reason" inevitably leads to paradox. Three replies are advanced: that priors are imprecise or of little weight, so that disagreement about them does not matter, within limits; that it (...) is possible to distinguish reasonable from unreasonable priors on logical grounds; and that in real cases disagreement about priors can usually be explained by differences in the background information. It is argued also that proponents of alternative conceptions of probability, such as frequentists, Bayesians and Popperians, are unable to avoid committing themselves to the basic principles of logical probability.

Various studies show moral intuitions to be susceptible to framing effects. Many have argued that this susceptibility is a sign of unreliability and that this poses a methodological challenge for moral philosophy. Recently, doubt has been cast on this idea. It has been argued that extant evidence of framing effects does not show that moral intuitions have an unreliability problem. I argue that, even if the extant evidence suggests that moral intuitions are fairly stable with respect to what intuitions we (...) have, the effect of framing on the strength of those intuitions still needs to be taken into account. I argue that this by itself poses a methodological challenge for moral philosophy. (shrink)

It does not take much to realize that, concerning the topic of Iran, the lack of response and general confusion from the Left within liberal, Western democracies is deeply symptomatic. That the perplexed responses of liberals seem to be characterized by a fetishization of the Iranian Other, reducing them to an empty screen onto which the liberal ideological subject may project their fantasy, prevents the Left from acknowledging that Iranian ideology functions as an over-identification with many of the excesses which (...) liberal ideology is so used to criticizing. The present work seeks to traverse this fantasy space, explicating the way Iran is considered to the object-cause of liberal desire and the consequences this conception has for the Left’s capacity to coherently respond to the present situation as it unfolds. Iran seems incapable of entering into the sphere of modernity, as any multiculturalist will be sure to emphasize, and yet, as any conservative will claim, in light of Iran’s control over such a huge percent of the world’s oil supply, as well as their refusal to engage in secular politics and attempts to develop nuclear technology, Iran threatens to disintegrate modernity itself. Both of these alternatives should be rejected as falling prey to the same fantastic projection to be avoided. (shrink)

The essential idea of Leibniz’s Theodicy was little understood in his time but has become one of the organizing themes of modern mathematics. There are many phenomena that are possible locally but for purely mathematical reasons impossible globally. For example, it is possible to build a spiral staircase that is rising at any given point, but it is impossible to build one that is rising at all points and comes back to where it started. The necessity is mathematically provable, so (...) not subject to exception by divine power. Leibniz’s Theodicy argues that God could improve the universe locally in many ways, but not globally. This paper defends Leibniz, giving positive reasons for believing that there are so many necessary interconnections between goods and evils that God is faced with a choice like the classic Trolley case, where all of the scenarios that could be chosen upfront contain evils, but some more than others. Local changes for the better seem easy to imagine, but a proper understanding of global constraints undermines the initial impression that they can be done without global cost. The paper concludes by explaining how the context of the Leibnizian argument makes it reasonable to pursue the issue of whether there are no worlds better than this one. (shrink)

This paper challenges the standard a priori/a posteriori distinction by looking at statements in which comprehension requires more that merely passive awareness of objects and their properties. A proposal is made to add to the traditional categories of knowledge, the “a positio,” characterized by active, intentional, and collective involvement of language users in the existence and nature of objects of reference needed for the truth of statements about various kinds of artifacts, broadly construed. The conditions of understanding statements about institutions, (...) institutional activity and standards of measurement are considered in some detail. (shrink)

If, as Richard Wollheim says, the Acquaintance Principle is ‘a well-entrenched principle in aesthetics,’ it would be surprising if there were not something true at which those who have asserted it have been aiming. I argue that the Acquaintance Principle cannot be true on any traditional epistemic interpretation, nor on any usability interpretation of the sort Robert Hopkins has recently suggested. I then argue for an interpretation of the principle that treats acquaintance as the end to which judgments of aesthetic (...) value are the means as opposed to the other way around. (shrink)

Recent theories of remembering and of reference (or singular thought) have de-emphasised the role causation was thought to play in mid- to late-twentieth century theorising. According to postcausal theories of remembering, such as simulationism, instances of the psychofunctional kind _remembering_ are not, in principle, dependent on appropriate causal chains running from some event(s) remembered to the occurrence of remembering. Instead they depend only on the reliability, or proper functioning, of the cognitive system responsible for their production. According to broadly reliabilist (...) accounts of _singular thought_, such thought is not, in principle, dependent on causal chains running from the object(s) of thought to the occurrence of thinking. Despite this common trend, accounts of the two phenomena have been pursued separately. In this paper, we argue that the two lines of research can profitably converge to address a neglected question: what enables occurrences of remembering to _refer_ to particular events, and what determines _which_ event a given occurrence of remembering refers to? We motivate and present a reliabilist account of reference-fixing for postcausal theories of remembering, focusing in particular on simulationism. We then show that this account draws attention to the possibility of _referential mnemic confabulation:_ cases where the reliability requirement for reference is met despite the improper functioning of the episodic construction system. We suggest that this makes sense of some underdiscussed phenomena described in the empirical literature on confabulation and argue that our reliabilist account of mnemic reference-fixing accommodates these more naturally than could causal theories of remembering.

This paper defends the usefulness of the concept of philosophical progress and the common assumption that philosophy and science aim to make the same, or a comparable, kind of progress. It does so by responding to Yafeng Shan's (2022) arguments that the wealth of research on scientific progress is not applicable or useful to philosophy, and that philosophy doesn't need a concept of progress at all. It is ultimately argued that while Shan's arguments are not successful, they reveal the way (...) forward in developing accounts of philosophical progress. (shrink)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)
