Philosophers of information, according to Luciano Floridi (The philosophy of information. Oxford University Press, Oxford, 2010, p 32), study how information should be “adequately created, processed, managed, and used.” A small number of epistemologists have employed the concept of information as a cornerstone of their theoretical framework. How this concept can be used to make sense of seemingly intractable epistemological problems, however, has not been widely explored. This paper examines Fred Dretske’s information-based epistemology, in particular his response to radical epistemological (...) skepticism. We discuss the relationship between information, evidence and knowledge in relation to the problem of skepticism and the options available to an information-based epistemology for dealing with it.

In recent years, the idea has been gaining ground that our traditional conceptions of knowledge and cognition are unduly limiting, in that they privilege what goes on inside the ‘skin and skull’ of an individual reasoner. Instead, it has been argued, knowledge and cognition need to be understood as embodied, situated, and extended. Whether these various interrelations and dependencies are ‘merely’ causal, or are in a more fundamental sense constitutive of knowledge and cognition, is as much a matter of controversy (...) as the degree to which they pose a challenge to ‘traditional’ conceptions of cognition, knowledge and the mind. In this paper we argue that when the idea of ‘extendedness’ is applied to a core concept in epistemology and the philosophy of science—namely, scientific evidence—things appear to be on a much surer footing. The evidential status of data gathered through extended processes—including its utility as justification or warrant—do not seem to be weakened by virtue of being extended, but instead are often strengthened because of it. Indeed, it is often precisely by virtue of this extendedness that scientific evidence grounds knowledge claims, which individuals may subsequently ascribe to themselves. The functional equivalence between machine-based gathering, filtering, and processing of data and human interpretation and assessment is the crucial factor in deciding whether evidence has been gathered, rather than the distinction between intra- and extracranial processes or individual and social processes. To prioritize biological processes here, and to assert the superiority of human cognitive capacities seems both arbitrary and unwarranted with respect to gathering evidence, and ultimately would lead to an unattractive skepticism about many of the methods used in science to gather evidence. In other words, conceiving of scientific evidence as ‘impersonal’ not only better captures the character of evidence-gathering in practice, but also makes sense of a large amount of evidence-gathering that ‘personal’ accounts fail to either acknowledge or accurately describe. Whilst we suggest it is likely that all internally-distributed evidence-gathering processes are merely contingently internal processes, a significant number of externally-distributed evidence-gathering processes are necessarily externally-distributed. Some evidence can only be gathered by extended epistemic agents. (shrink)

The topic of epistemic normativity has come to the fore of recent work in epistemology, and so naturally, theories of knowledge, truth and justification have been increasingly held accountable to preserving normative epistemological platitudes. Central to discussions of epistemic normativity are questions about epistemic agency and epistemic value. Here, our aim is to take up some of these issues as they come to bear on the rather unconventional brand of epistemology that was defended by Richard Rorty. Our purpose is to (...) explore whether Rorty’s epistemology—or perhaps his replacement for epistemology—can preserve these normative platitudes about epistemic agency, responsibility, achievement, and the value of knowledge. Our conclusion is a negative one: that Rorty’s commitments leave him firmly at odds with some of the most plausible assumptions about epistemic agency and epistemic value. (shrink)

My starting point is that discussions in philosophy about the ontology of technical artifacts ought to be informed by classificatory practices in engineering. Hence, the heuristic value of the natural-artificial distinction in engineering counts against arguments which favour abandoning the distinction in metaphysics. In this chapter, I present the philosophical equipment needed to analyse classificatory practices and then present a case study of engineering practice using these theoretical tools. More in particular, I make use of the Collectivist Account of Technical (...) Artifacts (CAT) according to which there are different classificatory practices for natural, artificial, and social objects. I demonstrate that in the community studied, artificial kinds are marked by distinctive classificatory practices. The presence of these distinctive classificatory practices in engineering with regard to artificial kinds should inform discussions about the ontology of technical artifacts just as the distinctive classificatory practices in natural science inform discussions about natural kinds.

Evidence that placebo acupuncture is an effective treatment for chronic pain presents a puzzle: how do placebo needles appearing to patients to penetrate the body, but instead sitting on the skin’s surface in the manner of a tactile stimulus, evoke a healing response? Previous accounts of ritual touch healing in which patients often described enhanced touch sensations suggest an embodied healing mechanism. In this qualitative study, we asked a subset of patients in a singleblind randomized trial in irritable bowel syndrome (...) to describe their treatment experiences while undergoing placebo treament. Analysis focused on patients’ unprompted descriptions of any enhanced touch sensations and any significance patients assigned to the sensations. We found in 5/6 cases, patients associated sensations including “warmth” and “tingling” with treatment efficacy. The conclusion offers a “neurophenomenological” account of the placebo effect by considering dynamic effects of attentional filtering on early sensory cortices, possibly underlying the phenomenology of placebo acupuncture.

How engineers know, and act on that knowledge, has a profound impact on society. Consequently, the analysis of engineering knowledge is one of the central challenges for the philosophy of engineering. In this article, we present a thematic multidisciplinary conceptual survey of engineering epistemology and identify key areas of research that are still to be comprehensively investigated. Themes are organized based on a survey of engineering epistemology including research from history, sociology, philosophy, design theory, and engineering itself. Five major interrelated (...) themes are identified: the relationship between scientific and engineering knowledge, engineering knowledge as a distinct field of study, the social epistemology of engineering, the relationship between engineering knowledge and its products, and the cognitive aspects of engineering knowledge. We discuss areas of potential future research that are underdeveloped or “undone.”. (shrink)

In _Civilization and Its Discontents_, Freud made abundantly clear what he thought about the biblical injunction, first articulated in Leviticus 19:18 and then elaborated in Christian teachings, to love one's neighbor as oneself. "Let us adopt a naive attitude towards it," he proposed, "as though we were hearing it for the first time; we shall be unable then to suppress a feeling of surprise and bewilderment." After the horrors of World War II, the Holocaust, Stalinism, and Yugoslavia, Leviticus 19:18 seems (...) even less conceivable—but all the more urgent now—than Freud imagined. In _The Neighbor_, three of the most significant intellectuals working in psychoanalysis and critical theory collaborate to show how this problem of neighbor-love opens questions that are fundamental to ethical inquiry and that suggest a new theological configuration of political theory. Their three extended essays explore today's central historical problem: the persistence of the theological in the political. In "Towards a Political Theology of the Neighbor," Kenneth Reinhard supplements Carl Schmitt's political theology of the enemy and friend with a political theology of the neighbor based in psychoanalysis. In "Miracles Happen," Eric L. Santner extends the book's exploration of neighbor-love through a bracing reassessment of Benjamin and Rosenzweig. And in an impassioned plea for ethical violence, Slavoj Žižek's "Neighbors and Other Monsters" reconsiders the idea of excess to rehabilitate a positive sense of the inhuman and challenge the influence of Levinas on contemporary ethical thought. A rich and suggestive account of the interplay between love and hate, self and other, personal and political, _The Neighbor_ will prove to be a touchstone across the humanities and a crucial text for understanding the persistence of political theology in secular modernity.

This paper describes a way of creating and maintaining a `dynamic encyclopedia', i.e., an encyclopedia whose entries can be improved and updated on a continual basis without requiring the production of an entire new edition. Such an encyclopedia is therefore responsive to new developments and new research. We discuss our implementation of a dynamic encyclopedia and the problems that we had to solve along the way. We also discuss ways of automating the administration of the encyclopedia.

Philip R. Shields shows that ethical and religious concerns inform even the most technical writings on logic and language, and that, for Wittgenstein, the need to establish clear limitations is both a logical and an ethical demand. Rather than merely saying specific things about theology and religion, major texts from the Tractatus to the Philosophical Investigations express their fundamentally religious nature by showing that there are powers which bear down upon and sustain us. Shields finds a religious view of the (...) world at the very heart of Wittgenstein's philosophy. "Shields argues that the appearance throughout Wittgenstein's writings of such concepts as ritual, limit, transgression, a change of will, pride, temptation, and judgment implies a relation between religion and the logical aspects of Wittgenstein's philosophy."-- Choice "Of the many recent books about Wittgenstein, Logic and Sin is one of the very few that are well worth having"--Fergus Kerr, Modern Theology "What Shields has uncovered in Wittgenstein's religious sensibility is something genuine and profound. . . . Shields has not just written an important book on Wittgenstein but an enlightening work that invites further reflection."--Eric O. Springsted, Cross Currents. (shrink)

The primary argument against mereological singularism—the view that definite plural noun phrases like ‘the students’ refer to “set-like entities”—is that it is ultimately incoherent. The most forceful form of this charge is due to Barry Schein, who argues that singularists must accept a certain comprehension principle which entails the existence of things having the contradictory property of being both atomic and non-atomic. The purpose of this paper is to defuse Schein’s argument, by noting three necessary and independently motivated restrictions on (...) the metalinguistic predicates ‘atom’ and ‘non-atom’: both are sort, property, and context-relative. With these restrictions in place, Schein’s problematic assumption becomes evident: his presumed singularist analysis of ‘non-atom’ conflates the metalanguage with the meta-metalanguage, i.e. the language used to talk about the metalanguage.

Many philosophical theories make comparisons between objects, events, states of affairs, worlds, or systems, and many such theories deliver plausible verdicts only if some of the elements they compare are ranked as ‘best.’ When the relevant ordering does not have such ‘best’ or ‘tied for best’ elements the theory wrongly falls silent or gives badly counterintuitive results. This paper develops ordering supervaluationism---a very general technique that allows any such theory to handle these problematic cases. Just as ordinary supervaluation helps us (...) save and generalize ‘uniqueness assuming’ theories, ordering supervaluationism helps us save and generalize ‘limit assuming’ theories. With so many otherwise attractive limit assuming theories, this is a sensible, methodologically conservative approach. (shrink)

In his latest book, Eric Scerri presents a completely original account of the nature of scientific progress. It consists of a holistic and unified approach in which science is seen as a living and evolving single organism. Instead of scientific revolutions featuring exceptionally gifted individuals, Scerri argues that the "little people" contribute as much as the "heroes" of science. To do this he examines seven case studies of virtually unknown chemists and physicists in the early 20th century quest to (...) discover the structure of the atom. They include the amateur scientist Anton van den Broek who pioneered the notion of atomic number as well as Edmund Stoner a then physics graduate student who provided the seed for Pauli's Exclusion Principle. Another case is the physicist John Nicholson who is virtually unknown and yet was the first to propose the notion of quantization of angular momentum that was soon put to good use by Niels Bohr. Instead of focusing on the logic and rationality of science, Scerri elevates the role of trial and error and multiple discovery and moves beyond the notion of scientific developments being right or wrong. While criticizing Thomas Kuhn's notion of scientific revolutions he agrees with Kuhn that science is not drawn towards an external truth but is rather driven from within. The book will enliven the long-standing debate on the nature of science, which has increasingly shied away from the big question of "what is science?". (shrink)

In Phenomenology of Spirit (1806) Hegel is often held to have announced the end of history, where 'history' is to be understood as the long pursuit of ends towards which humanity had always been striving. In this, the first book in English to thoroughly critique this entrenched view, Eric Michael Dale argues that it is a misinterpretation. Dale offers a reading of his own, showing how it sits within the larger schema of Hegel's thought and makes room for an (...) understanding of the 'end of history' as Hegel intended. Through an elegant analysis of Hegel's philosophy of history, Dale guides the reader away from the common misinterpretation of the 'end of history' to other valuable elements of Hegel's arguments which are often overlooked and deserve to endure. His book will be of great interest to scholars and advanced students of Hegel, the philosophy of history, and the history of political thought. (shrink)

An enduring question in the philosophy of science is the question of whether a scientific theory deserves more credit for its successful predictions than it does for accommodating data that was already known when the theory was developed. In The Paradox of Predictivism, Eric Barnes argues that the successful prediction of evidence testifies to the general credibility of the predictor in a way that evidence does not when the evidence is used in the process of endorsing the theory. He (...) illustrates his argument with an important episode from nineteenth-century chemistry, Mendeleev's Periodic Law and its successful predictions of the existence of various elements. The consequences of this account of predictivism for the realist/anti-realist debate are considerable, and strengthen the status of the 'no miracle' argument for scientific realism. Barnes's important and original contribution to the debate will interest a wide range of readers in philosophy of science. (shrink)

The law of desire has been proposed in several forms, but its essential claim is that agents always act on their strongest proximal action motivation. This law has threatening consequences for human freedom, insofar as it greatly limits agents’ ability to do otherwise given their motivational state. It has proven difficult to formulate a version that escapes counterexamples and some categorically deny its truth. Noticeable by its absence in the literature is any attempt to provide an argument for the law (...) of desire – I propose such an argument here. It is noted that Sripada's “divided mind” theory of willpower provides a counterexample to the version of the law of desire my argument defends, but I note that a reformulated version of the law of desire survives this critique. I conclude that there is a serious case for the law of desire, and note the broader implications of this. (shrink)

In the 1640’s Elisabeth of Bohemia and René Descartes engaged in a philosophically rich correspondence. The most well-known aspect of the correspondence begins with a question Elisabeth asks Descartes about his account of the interaction between soul and body. This objection, often called the ‘problem of interaction’, has received much attention in contemporary scholarship and this attention frequently focuses on the exchange between Elisabeth and Descartes. Following the lead of Descartes himself, the majority of scholars treat the problem of interaction (...) as the core, or even the entirety, of Elisabeth’s objections to Descartes from this stage in the correspondence. In this paper I argue that the driving force of Elisabeth’s objections to Descartes’ account is not the problem of interaction. Rather, Elisabeth’s objections to Descartes fundamentally concern Descartes’ account of the nature of the soul. While Elisabeth clearly offers the problem of interaction, it is only one of several worries each of which is designed to show that Descartes’ account of the soul is insufficient. I argue that Elisabeth raises three distinct problems to Descartes’ account of the nature of the soul: the causal interface problem, the vapors problem and the principal attribute problem. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUME ON CONTINUED EXISTENCE AND THE IDENTITY OF CHANGING THINGS Most discussions of Hume's rather cursory treatment of coherence as a factor in generating belief in what he calls the continu' d existence of objects in Of Scepticism with Regard to the Senses, have taken a common line in interpreting the nature of the problem Hume's treatment is designed to solve. For instance, perhaps the two most ex2 3 (...) tensive discussions, those of Price and Gomberg seem to agree that the problem is: how do we fill in the gaps among our perceptions, complete sequences or series that are incomplete, and come to believe in the existence of a world of unperceived objects. At the same time such discussions have focussed on the issue of whether the inference from the coherence of our perceptions to belief in the continued existence of objects (ICCE) is, as Hume claims, distinguishable from causal inference. Hume is read in such a way that ICCE if not causal is at least quasi-causal; that is, the only difference for Hume between the two sorts of inference has been taken to be one concerning the evidence on which each is based — causal inferences on past constant conjunctions or uniformities, ICCE on something less. I believe that these discussions have invariably omitted a key factor in understanding Hume's treatment of coherence, one that I want to point out and develop in this paper. Hume's discussion of coherence, like his discussion of constancy, is bound up with the concept of identity; for belief in the continued existence of an object, which coherence generates, is a belief about its identity. Hence a causal inference is distinguished from ICCE by Hume as only the latter necessarily involves belief in the identity of an object over time. Once this is recognized, we can view Hume's discussion^of coherence as requiring an answer to the question: "How do we come to believe in the identity of changing things?" I want to consider two interpretations of 106. the exact nature of ICCE for Hume — one suggested by examples offered in his discussion of coherence, the other suggested by remarks about the concept of identity in other sections of Part Four of Book One of the Treatise — and to argue that neither satisfactorily answers this question. This failure raises doubts not only about ICCE but about the tenability of Hume's characterization of the "vulgar" view of perception and his view of identity. When Hume first answers the question, "What qualities of our impressions or perceptions lead us to attribute to them a distinct and continued existence,?" by isolating the qualities of constancy and coherence, I think it is clear that the former is invoked to account for objects which are, at least in a relative sense, unchanging, which have always appear 'd to me in the same order and return upon me without the least alteration (T194), while the latter is invoked especially, if not solely, to account for objects that underto rather large changes over time, things which after a little absence or interruption may become hardly knowable. (T195) Hume's example concerns a fire in his chamber, which undergoes great change from the moment he leaves (or perhaps the moment it is lighted) to the time he returns (or perhaps the time it is a bunch of glowing embers), but which, nevertheless, compared to other fires undergoes a like alteration...in a like time. (T195) Whatever more coherence can do, it is required, at least initially, to account for just those cases which cannot be subsumed under constancy, in other words, cases in which changing objects are taken to possess distinct and continued existence. In the famous paragraph following his initial comments on coherence, Hume seemingly proceeds to explain how coherence gives rise to belief in continued existence. The account runs basically as follows. Hume hears a noise, as of a door turning; he sees a porter coming toward him. But, Hume says, I never have observ' d3 that this noise could proceed from anything but the motion of a 107. door; and therefore conclude, that the present phaenomenon is a contradiction to all past experience...

The purpose of this work is to elaborate an empirically grounded mathematical model of the magnitude of consequences component of "moral intensity", 366, 1991) that can be used to evaluate different ethical situations. The model is built using the analytical hierarchy process and empirical data from the legal profession. One contribution of our work is that it illustrates how AHP can be applied in the field of ethics. Following a review of the literature, we discuss the development of the model. (...) We then illustrate how the model can be used to rank-order three well-known ethical reasoning cases in terms of the magnitude of consequences. The work concludes with implications for theory, practice, and future research. Specifically we discuss how this work extends the previous work by Collins regarding the nature harm variable. We also discuss the contribution this work makes in the development of ethical scenarios used to test hypotheses in the field of business ethics. Finally, we discuss how the model can be used for after-action review, contribute to organizational learning, train employees in ethical reasoning, and aid in the design and development of decision support systems that support ethical reasoning.

Spinoza’s Ethics makes reference to three kinds of knowledge that humans are capable of winning: imagination, reason and intuitive knowledge of God. Of these, imagination is necessarily inadequate while the latter two are necessarily adequate. In other words, we remain passive in the first type of knowledge, but come into our power of acting in the latter two. The passage from the first to the second and third types of knowledge, however, remains, in Spinoza’s text, rather obscure. This paper seeks (...) to come to terms with how exactly the passage from passion to action is made in the Ethics while locating this particular problematic as a site at which various interpretations of Spinoza diverge with considerable stakes. I thus focus on Gilles Deleuze’s proposed answer to this problem as well as Pierre Macherey’s critique of Deleuze’s reading. I argue that the disagreement between Macherey and Deleuze is not merely interpretive, but rather indicates some of the stakes involved in assessing Spinoza’s theory of the passions and the imagination. An ‘optimistic’ appraisal of these features might lead one to Deleuze’s affirmationist project, while Macherey’s pessimism concerning the two might take a Spinozist politics in quite the opposite direction. I appreciate and assess multiple aspects of Macherey’s critique while nonetheless arguing that they do not prove damning for Deleuze’s affirmationist picture. I conclude with an analysis of vacillation of mind in Deleuze’s Spinoza, and place Deleuze’s thoughts on this note in conversation with his earlier reading of Nietzsche. (shrink)

Written in 1839 and chosen as the winning entry in a competition held by the Royal Norwegian Society of Sciences, Schopenhauer's Prize Essay on the Freedom of the Will marked the beginning of its author's public recognition and is widely regarded as one of the most brilliant and elegant treatments of free will and determinism. Schopenhauer distinguishes the freedom of acting from the freedom of willing, affirming the former while denying the latter. He portrays human action as thoroughly determined but (...) also argues that the freedom which cannot be established in the sphere of human action is preserved at the level of our innermost being as individuated will, whose reality transcends all dependency on outside factors. This volume offers the text in a previously unpublished translation by Eric F. J. Payne, the leading twentieth-century translator of Schopenhauer into English, together with a historical and philosophical introduction by Günter Zöller. (shrink)

This book analyzes crucial episodes in the history of American higher education in order to discover the best way to rescue the humanities. It urges apologists to stop focusing on the humanistic disciplines as inculcators of poorly defined skills and envisions a globalized approach to education based on humanistic masterworks.

Statt von einem Guattari-Effekt auf Deleuze muss man von einem Guattari-Deleuze-Effekt sprechen, um ein wechselseitiges Einwirken in einem gemeinsamen Projekt zu beschreiben, das mit dem Herausgehen aus der klassischen Psychoanalyse beginnt und in den Umbau der Philosophie in der Öffnung auf ihr Außen mündet. Dieser Umbau lässt das Paradigma der Interpretation ebenso hinter sich wie jenes der Struktur. In der Kritik an Lacan vollziehen Deleuze und Guattari die Abkehr vom Postulat des Primats der Sprache als Struktur und eines durch sie (...) immer schon konstituierten und vom Realen ebenso wie von kollektiven Individuationsprozessen abgeschnittenen Subjekts. Die heterogenen Ausdrucksmaterien Hjelmslevs, die das Aufbrechen der Opposition von Sprachzeichen und Materie ermöglichen sowie die Konzepte der Wunschmaschine und mehr noch des Gefüges eröffnen den Weg hin zu einem Politisch-Werden der Philosophie als Wiederaneignung der Produktionsmittel kollektiver Subjektivität. In order to understand the collaborators' mutual impact in a joint project that began with Deleuze and Guattari's transgression of classical psychoanalysis and advanced to their complete remodeling of philosophy, the notion of a »Guattari-Deleuze-effect« is more adequate than the presumption an unilateral »Guattari-effect« upon Deleuze. Furthermore, Deleuze's and Guattari's concerted efforts leave the paradigms of »interpretation« and »structure« behind; in their critique of Lacan, Deleuze and Guattari turn away from the primate of language as structure and the postulate of an always already constituted subject that is cut off both from the real and from collective processes of individuation. Finally, the concept of a heterogeneous »matter of expression,« which, borrowed from Hjelmslev, allows opening up the opposition between linguistic sign and matter, as well as the concepts of »desiring-machine« and »assemblage«, clear the way towards a becoming-political of philosophy, understood as reappropriation of collective subjectivity's means of production.

To date, emotion research has primarily focused on the experience and display of the emoter. However, of equal, if not more, importance is how such displays impact and guide the behavior of an observer. We incorporate a functionalist framework of emotion to examine the development of differential responding to discrete emotion, theorize on what may facilitate its development, and hypothesize the functions that may underlie such behavioral responses. Although our review is focused primarily on development, the theoretical and methodological ideas (...) laid out are relevant for researchers of emotion at all ages. (shrink)
