Does the centralization of the Web change both the diffusion of knowledge and the philosophical definition of knowledge itself? By exploring the origins of the Semantic Web in the philosophy of Carnap and of Google’s machine learning approach in Heidegger, we demonstrate that competing philosophical schools are deeply embedded in artificial intelligence and its evolution in the Web. Finally, we conclude that a decentralized approach to knowledge is necessary in order to bring the Web to its full potential as project (...) for the spread of human autonomy. (shrink)

Proceedings of PhiloWeb 2012, workshop at WWW 2012, on the philosophy of the Web.

We examine a crucial question for the World Wide Web: What does a Uniform Resource Identifier (URI) mean? Crucial for the next-generation Semantic Web, can it refer to things outside web-pages? The Web is a universal information space for naming and accessing information via URIs. However, the classical philosophical problems of meaning and reference that have been the source of debate within the philosophy of language return when the Web is given as the foundation for a knowledge representation with the (...) Semantic Web. Debates on the Semantic Web about the meaning and referential status of a URI are explored as analogues to debates about the meaning and reference of names in the philosophy of language. Three main positions are inspected: the logical position, as exemplified by the descriptivist theory of reference, the direct reference position, as exemplified by Putnam and Kripke’s causal theory of reference, and a Wittgensteinian position that views URIs as a public language, as exemplified by Web search engines. These positions show that debates within the philosophy of language are alive and well on the Web, and so in the philosophy of computer science. (shrink)

Built upon the foundations of the Internet, the World Wide Web has been the most significant technological development within recent history, sparking a reformulation of both capitalism and resistance. The Web is defined as a « universal information space » by its inventor Tim Berners-Lee of the W3C, reflecting the universal scope of politics and struggle today. Yet while its effects have been scrutinized, the Web itself has received little inquiry. The composition of the governing networks that control the infrastructure (...) of the Web have only recently been engaged with by activists with the ICANN affair and WSIS protests. The Web is governed by a network that is composed of an « immaterial aristocracy » of radical democratic « hackers », corporations such as Google and Microsoft, and non-governmental organizations such as the Internet Engineering Task Force and World Wide Web Consortium. These networks continually negotiate between the needs of global capitalism and the desires of immaterial labour on the Web. (shrink)

It has been nearly half a century since the publication of Harry Braverman’s Labor and Monopoly Capital. That, along with Michael Burawoy’s subsequent interrogation of Braverman—Manufacturing Consent—set the terms for a robust and enduring research agenda that has focused on labor processes: the deskilling of work, managerial control over workers, consent, and the extraction of surplus value. This article endeavors to advance the labor process paradigm by highlighting recruitment as a tool by which employers maximize the likelihood that they (...) will hire people who will consent to their objectives, broadly defined. Drawing on a broad range of literatures, we show how recruitment and hiring practices constitute part of an overarching apparatus of control wherein managers imagine that particular people will be ideal for particular jobs and positions. We conclude by sketching a research agenda that sociologists of work and labor processes might undertake in order to understand these issues more thoroughly. (shrink)

The aim of Massimiliano Tomba’s Insurgent Universality is to return to Marxism’s original historical vocation by freeing it from the hegemony of the exchange system and the encompassing agency of value. At the heart of this project appears the recognition that time, space and thus history have been captured by capitalism and transformed into categories of its own to organise people and social relationships for capital’s programme of accumulation. In this way, capital has been able to hijack history and invert (...) it into a representation of the real, into a historical trompe-l’œil instead of ‘presentify(ing) the past’. In this regard contemporising the past is an act of intervening in history and actualising it rather than representing it. Through this operation Tomba is able to retrieve an inventory of repressed and forgotten histories, which will unveil the sources of an ‘alternate legacy of modernity’ and radical political possibilities for the present.

Panqualityism, recently defended by Sam Coleman, is a variety of Russellian monism on which the categorical properties of fundamental physical entities are qualities, or, in Coleman’s exposition, unconscious qualia. Coleman defends a quotationalist, higher-order thought version of panqualityism. The aim of this paper is, first, to demonstrate that a first-order representationalist panqualityism is also available, and to argue positively in its favor. For it shall become apparent that quotationalist and first-order representationalist panqualityism are, in spite of their close similarities, radically (...) different theories: quotationalist panqualityism locates qualities in the subject of an experience, while first-order panqualityism locates qualities in the world. I argue that this makes quotationalist panqualityism implausible and first-order, representationalist panqualityism a highly natural, elegant, and intuitive theory. (shrink)

As well as disagreeing about how much one should donate to charity, moral theories also disagree about where one should donate. In light of this disagreement, how should the morally uncertain philanthropist allocate her donations? In many cases, one intuitively attractive option is for the philanthropist to split her donations across all of the charities that are recommended by moral views in which she has positive credence, with each charity’s share being proportional to her credence in the moral theories that (...) recommend that particular charity. Despite the fact that something like this approach is already being used by real-world philanthropists to distribute billions of dollars of donations, it is not supported by any of the approaches to moral uncertainty that have been proposed thus-far in the philosophical literature. In this paper, we will develop a bargaining-based approach to moral uncertainty that honors the proportionality intuition in favor of splitting one’s donations. We also show how this bargaining-based approach has several further advantages over the best alternative proposals. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:IntroductionSchelling and the EnvironmentChelsea C. Harry (bio)Scientists overwhelmingly agree that climate change is anthropogenic, caused by our greenhouse gas emissions.1 Given the evidence that exists, we should be able to convince ourselves to change the everyday behaviors resulting in these emissions. If we hope to save ourselves, other animals, plants, and the environment from a devastating future, then why would we continue to use fossil fuels?The answer here (...) is not an easy one. And yet, the ancient Greek philosopher, Aristotle, provides us with a possible cause. In his most famous work on ethics,2 Aristotle argued that being weak-willed, suffering from what he called, “akrasia,” is the reason we do things that we know we shouldn’t do. It is a condition that results when desire wins over reason. For example, I eat a chocolate bar when I know I should eat a salad because my desire for chocolate wins over what I have reasoned to be best for my health. Simply put, reason might be what distinguishes us from other animals and plants, but it is not always our most powerful faculty. It stands both to experience and to reason, then, that rational decision might not be what is going to get us out of this climate crisis. Then, what is?In this special issue, we hear from five contemporary scholars of the 18th–19th century German philosopher, F.W.J. Schelling, an oft-called “protean thinker” whose prolific, sometimes creative, and diverse works spanned over seventy years. A onetime roommate of Hegel and Hölderlin, Schelling’s works are lesser-known outside specialist circles, and yet one finds that his prescient insights continue to have much to offer. This is especially true vis-à-vis the climate crisis, as Schelling was the first post-Kantian philosopher to take nature seriously. He eschewed the modern, Kantian, and post-Kantian trend to focus on [End Page 1] ipseity, the self, and on what we as humans can rationally know. Instead, he returned to metaphysics and argued for a wholistic conception and experience of life—all life. For Schelling, humans are rational as an expression of nature, rather than as an exception to nature. As John Sallis put it so well as he argued for the Platonic influence in Schelling: “For what Schelling rewrites within the text of modern philosophy is a discourse on nature.”3 Sallis then reminds us that in Schelling’s 1809 text, Philosophical Investigations of the Essence of Human Freedom (“Die Freiheitschrift”), he openly criticizes post-Cartesian philosophy generally for its exclusion of nature; “All modern European philosophy since it began with Descartes has this common defect, that nature does not exist for it and that it lacks a living ground.”4 Schelling’s intention was to resolve the defect, and because of his efforts in this regard, his work has something to say to us about our relationship to the environment.The idea to think about what Schelling can offer us in our current climate crisis is hardly new. In 2014, the North American Schelling Society (NASS), hosted by Bruce Matthews and Bard College, thematized its third international conference on “Schelling in the Anthropocene,” asking scholars to think beyond modern philosophy’s legacy of the human/nature divide and to discuss Schelling’s contribution to the anthropogenic environmental crisis we currently face. Since then, published work on this topic includes: Bruce Matthews’s, “Schelling in the Anthropocene,”5 Christopher Lauer’s, “Confronting the Anthropocene,” 6 and Vincent Lee’s, “Schelling and the Sixth Extinction.”7 Other journals have published special issues on related topics, including McGrath et al. Schelling After Theory special issue of Symposium: Canadian Journal of Continental Philosophy, McGrath et al. The Many Faces of F.W.J. Schelling special issue of Analecta Hermeneutica, Tritten et al. Nature, Speculation, and the Return to Schelling special issue of Angelaki: Journal of the Theoretical Humanities, and Bahoh, et al. Philosophies of Nature special issue of Comparative and Continental Philosophy. While this is by no means an exhaustive list, other contemporary thinkers who have been part of this conversation include: Kyla Bruff, Charlotte Alderwick, Manfred Frank, Markus Gabriel, Iain Grant,8 Lore...

In _Archaism and Actuality_ eminent Marxist historian Harry Harootunian explores the formation of capitalism and fascism in Japan as a prime example of the uneven development of capitalism. He applies his theorization of subsumption to examine how capitalism integrates and redirects preexisting social, cultural, and economic practices to guide the present. This subsumption leads to a global condition in which states and societies all exist within different stages and manifestations of capitalism. Drawing on Japanese philosophers Miki Kiyoshi and Tosaka (...) Jun, Marxist theory, and Gramsci’s notion of passive revolution, Harootunian shows how the Meiji Restoration of 1868 and its program dedicated to transforming the country into a modern society exemplified a unique path to capitalism. Japan’s capitalist expansion in the nineteenth and twentieth centuries, rise as an imperial power, and subsequent transition to fascism signal a wholly distinct trajectory into modernity that forecloses any notion of a pure or universal development of capitalism. With _Archaism and Actuality_, Harootunian offers both a retheorization of capitalist development and a reinterpretation of epochal moments in modern Japanese history. (shrink)

One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted. Most people are rather confident of their ability to recognize bullshit and to avoid being taken in by it. So the phenomenon has not aroused much deliberate concern. We have no clear understanding of what bullshit is, why there is so much of it, or what functions (...) it serves. And we lack a conscientiously developed appreciation of what it means to us. In other words, as Harry Frankfurt writes, "we have no theory." Frankfurt, one of the world's most influential moral philosophers, attempts to build such a theory here. With his characteristic combination of philosophical acuity, psychological insight, and wry humor, Frankfurt proceeds by exploring how bullshit and the related concept of humbug are distinct from lying. He argues that bullshitters misrepresent themselves to their audience not as liars do, that is, by deliberately making false claims about what is true. In fact, bullshit need not be untrue at all. Rather, bullshitters seek to convey a certain impression of themselves without being concerned about whether anything at all is true. They quietly change the rules governing their end of the conversation so that claims about truth and falsity are irrelevant. Frankfurt concludes that although bullshit can take many innocent forms, excessive indulgence in it can eventually undermine the practitioner's capacity to tell the truth in a way that lying does not. Liars at least acknowledge that it matters what is true. By virtue of this, Frankfurt writes, bullshit is a greater enemy of the truth than lies are. (shrink)

Moral latitude is only ever a matter of coincidence on the most popular decision procedure in the literature on moral uncertainty. In all possible choice situations other than those in which two or more options happen to be tied for maximal expected choiceworthiness, Maximize Expected Choiceworthiness implies that only one possible option is uniquely appropriate. A better theory of appropriateness would be more sensitive to the decision maker’s credence in theories that endorse agent-centred prerogatives. In this paper, we will develop (...) and defend a modified version of this view that allows for agent-centred prerogatives and supererogation as part of its verdicts about appropriateness. (shrink)

The first collection of Leibniz's key writings on the binary system, newly translated, with many previously unpublished in any language. -/- The polymath Gottfried Wilhelm Leibniz (1646–1716) is known for his independent invention of the calculus in 1675. Another major—although less studied—mathematical contribution by Leibniz is his invention of binary arithmetic, the representational basis for today's digital computing. This book offers the first collection of Leibniz's most important writings on the binary system, all newly translated by the authors with many (...) previously unpublished in any language. Taken together, these thirty-two texts tell the story of binary as Leibniz conceived it, from his first youthful writings on the subject to the mature development and publication of the binary system. -/- As befits a scholarly edition, Strickland and Lewis have not only returned to Leibniz's original manuscripts in preparing their translations, but also provided full critical apparatus. In addition to extensive annotations, each text is accompanied by a detailed introductory “headnote” that explains the context and content. Additional mathematical commentaries offer readers deep dives into Leibniz's mathematical thinking. The texts are prefaced by a lengthy and detailed introductory essay, in which Strickland and Lewis trace Leibniz's development of binary, place it in its historical context, and chart its posthumous influence, most notably on shaping our own computer age.

Shelly Kagan has recently defended the view that it is morally worse for a human being to suffer some harm than it is for a lower animal (such as a dog or a cow) to suffer a harm that is equally severe (ceteris paribus). In this paper, I argue that this view receives rather less support from our intuitions than one might at first suppose. According to Kagan, moreover, an individual’s moral status depends partly upon her ‘modal capacities.’ In this (...) paper, I argue that the most natural strategy for justifying Kagan’s theory faces some important challenges. More generally, I argue that philosophers who wish to defend the view that human beings have a higher moral status than that of the lower animals face a dilemma. Either their theory of moral status will imply (unacceptably) that some severely cognitively impaired human beings have a significantly lower moral status than that of typical human beings, or these philosophers will be forced to ground moral status in a set of properties so far removed from a subject’s actual capacities that it will become difficult to see why these kinds of properties should have such moral importance.

What is education for? Should it produce workers or educate future citizens? Is there a place for faith schools - and should patriotism be taught? In this compelling and controversial book, Harry Brighouse takes on all these urgent questions and more. He argues that children share four fundamental interests: the ability to make their own judgements about what values to adopt; acquiring the skills that will enable them to become economically self-sufficient as adults; being exposed to a range of (...) activities and experiences that will enable them to flourish in their personal lives; and developing a sense of justice. He criticises sharply those who place the interests of the economy before those of children, and assesses the arguments for and against the controversial issues of faith schools and the teaching of patriotism. Clearly argued but provocative, On Education draws on recent examples from Britain and North America as well as famous thinkers on education such as Aristotle and John Locke. It is essential reading for anyone interested in the present state of education and its future. (shrink)

'Mass terms', words like water, rice and traffic, have proved very difficult to accommodate in any theory of meaning since, unlike count nouns such as house or dog, they cannot be viewed as part of a logical set and differ in their grammatical properties. In this study, motivated by the need to design a computer program for understanding natural language utterances incorporating mass terms, Harry Bunt provides a thorough analysis of the problem and offers an original and detailed solution. (...) An extension of classical set theory, Ensemble Theory, is defined, and this provides the conceptual basis of a framework for the analysis of natural language meaning which Dr Bunt calls Two-level model-theoretic semantics. The validity of the framework is convincingly demonstrated by the formal analysis of a fragment of English including sentences with quantified and modified mass terms. Separate chapters of the book are devoted to an axiomatic definition of Ensemble Theory and a detailed discussion of its status as a mathematical formalism. (shrink)

Wolfson's systematic presentation of the philosophy of Spinoza has long been a classic. It is with pride that we make it available again in a one-volume edition.

This book is a contribution both to Aristotle studies and to the philosophy of nature, and not only offers a thorough text based account of time as modally potentiality in Aristotle’s account, but also clarifies the process of “actualizing time” as taking time and looks at the implications of conceiving a world without actual time. It speaks to the resurgence of interest in Aristotle’s natural philosophy and will become an important resource for anyone interested in Aristotle’s theory of time, of (...) its relationship to Aristotle’s larger project in the Physics, and to time’s place in the broader scope of Aristotelian natural science. Graduate students and scholars researching in this area especially will find the authors arguments provocative, a welcome addition to other recent publications on Aristotle’s Treatise on Time. ​.

Darwin’s theory predicts that linguistic behavior gradually evolved out of animal forms of communication. However, this prediction is confronted by the conceptual problem that there is an essential difference between signaling and linguistic behavior: using words is a normative practice. It is argued that we can resolve this problem if we note that language evolution is the outcome of an evolutionary transition, and observe that the use of words evolves during ontogenesis out of babbling. It is discussed that language evolved (...) as the result of an expansion of the vocalizing powers of our ancestors. This involved an increase in the volitional control of our speech apparatus, but also the evolution of socially guided learning. It resulted in unique human abilities, namely doing things with words and later reasoning and giving reasons. (shrink)

Having outlined a theory of bullshit and falsehood, Harry G. Frankfurt turns to what lies beyond them: the truth, a concept not as obvious as some might expect. Our culture's devotion to bullshit may seem much stronger than our apparently halfhearted attachment to truth. Some people won't even acknowledge "true" and "false" as meaningful categories, and even those who claim to love truth cause the rest of us to wonder whether they, too, aren't simply full of it. Practically speaking, (...) many of us deploy the truth only when absolutely necessary, often finding alternatives to be more saleable, and yet somehow civilization seems to be muddling along. But where are we headed? Is our fast and easy way with the facts actually crippling us? Or is it "all good"? Really, what's the use of truth, anyway? With the same leavening wit and commonsense wisdom that animates his pathbreaking work On Bullshit, Frankfurt encourages us to take another look at the truth: there may be something there that is perhaps too plain to notice but for which we have a mostly unacknowledged yet deep-seated passion. His book will have sentient beings across America asking, "The truth—why didn't I think of that?". (shrink)

ABSTRACT This article considers the second treatise of Schelling's Abhandlungen zur Erläuterung des Idealismus der Wissenschaftslehre, a lesser-known work from the early Schelling. Here, Schelling proposes to defend the critical position insofar as it purports to be a system based on human reason, but instead he issues a backhanded critique of the assumption on behalf of the critical philosophers to try and limit the bounds of pure reason by means of their own use of reason. Schelling then offers an alternative (...) way to think about the relationship of mind and matter in nature. This article argues that Schelling's actual explanation of the critical philosophy as a position founded by reasonable minds ultimately belies his promise to defend it, thus calling into question that Schelling's thought prior to 1800 was a mere reiteration of Kantian/Fichtean transcendentalism.

The Russian invasion of Ukraine on February 24, 2022, has already caused large amounts of greenhouse gas (GHG) emissions and will continue to do so for manyyears after hostilities have ceased mainly because of the emissions linked to the rebuilding of destroyed or damaged housing, public buildings, infrastructure, factories, and the like. My aim in this paper is to discuss how in a time of climate emergency such emissions of war should impact the political morality of states initiating, continuing, and (...) ending war (through a just and enduring peace) as understood by just war theory (JWT). My point of departure is a study by Lennard de Klerk and six co-authors detailing the emissions of the first year of the Russo-Ukrainian war. (shrink)

One of the logical problems with which Arthur Prior struggled is the problem of finding, in Prior’s own phrase, a “logic for contingent beings.” The difficulty is that from minimal modal principles and classical quantification theory, it appears to follow immediately that every possible object is a necessary existent. The historical development of quantified modal logic (QML) can be viewed as a series of attempts---due variously to Kripke, Prior, Montague, and the fee-logicians---to solve this problem. In this paper, I review (...) the extant solutions, finding them all wanting. Then I suggest a new solution inspired by Kripke’s theory of rigid designation and Kaplan’s logic of demonstratives, the latter in particular. It turns out that the basic mechanism of Kaplan’s logic can be exploited to yield a version of QML that will serve as a viable logic for contingent beings. This result, as I show, sheds new light on the problems of singular negative existential propositions, the question of actualism, the question of the existence of the contingent a priori, the relation between logical truth and necessity, and various modal problems and paradoxes going back to Chrysippus, Ramsey, and Moore.
