We propose an analogy between optical holography and neural behavior as a hypothesis about the physical mechanisms of neural reuse. Specifically, parameters in optical holography (frequency, amplitude, and phase of the reference beam) may provide useful analogues for understanding the role of different parameters in determining the behavior of neurons (e.g., frequency, amplitude, and phase of spiking behavior).

Descartes' Meditations is one of the most thoroughly analyzed of all philosophical texts. Nevertheless, central issues in Descartes' thought remain unresolved, particularly the problem of the Cartesian Circle. Most attempts to deal with that problem have weakened the force of Descartes' own doubts or weakened the goals he was seeking. In this book, Stephen I. Wagner gives Descartes' doubts their strongest force and shows how he overcomes those doubts, establishing with metaphysical certainty the existence of a non-deceiving God (...) and the truth of his clear and distinct perceptions. Wagner's innovative and thorough reading of the text clarifies a wide range of other issues that have been left unclear by previous commentaries, including the nature of the cogito discovery and the relationship between Descartes' proofs of God's existence. His book will be of great interest to scholars and upper-level students of Descartes, early modern philosophy and theology. (shrink)

This paper spells out the implications, for Descartes's theory of ideas, of my earlier paper, "Descartes's Wax: Discovering the Nature of Mind." I show that my reading of the wax investigation provides a number of clarifications of Descartes's Meditation III discussion of ideas. My reading of Meditation III provides a ground, internal to the Meditations for Descartes's claims about objective reality, the causal laws, material falsity and the idea of God. I show that Descartes's claims and conclusions regarding these issues (...) is strengthened by the perspective I have provided. (shrink)

Following several earlier, relatively obscure occurrences of the term in Latin and French sources, the concept of nihilism first enters the broader philosophical discussion in Europe toward the end of the eighteenth century as a critique of German idealism, above all that of Kant and Fichte. Although essential scholarship on this early history has long been available in German, it has remained largely neglected by discussions of nihilism in English. Olson’s contribution on “nihilism” in Edwards’ standard Encyclopedia of Philosophy, though (...) certainly dated, is perhaps typical. Nietzsche, of course, is presented as the most prominent historical figure, with brief mention given to Russian origins and to nineteenth-century uses of the term as a condemnation of atheism. Yet the fundamental philosophical development of nihilism in the context of German idealism receives no attention whatsoever. At least as early as 1900, German scholars had already traced the first use of the concept back to Jacobi, specifically to his influential “Circular Letter to Fichte” of 1799. However, only the most recent studies in English even begin to acknowledge this crucial early development. (shrink)

This chapter discusses a re-emerging topic in Cartesian scholarship—mind and body interaction. A number of thinkers, from his contemporaries onward, have maintained that Descartes' account of his two substances rules out the possibility of the interaction that he attempted to defend. Often, however, the ground for asserting this impossibility has been left less than explicit. Recent discussion has attempted to clarify the issue by asking whether there can be specified grounds within Descartes' philosophy which are sufficient to rule out mind–body (...) interaction. There are three elements of Descartes' thinking which might seem to create problems for mind–body interaction—his insistence that mind and body are absolutely distinct substances, his own restrictions on possible causal relations, and his views on the freedom of the will. Recent work has focused on the first two of these issues. The chapter's goal is to suggest that an essential element of Descartes' worldview has been overlooked in this recent discussion, and to show that once it is taken into account many of the apparent difficulties about Cartesian interaction can be resolved.

THIS PAPER PROVIDES A READING OF DESCARTES' COGITO WHICH RESOLVES THE PROBLEMS ENCOUNTERED BY THE OTHER PREVALENT ANALYSES OF HIS THOUGHT. I FIRST INDICATE THE WAYS IN WHICH THE INFERENTIAL AND PERFORMATIVE VIEWS FAIL TO ADEQUATELY EXPLICATE DESCARTES' OWN STATEMENTS REGARDING THE COGITO. I THEN SET OUT MY "GENERATIVE VIEW" AND SHOW THAT IT PROVIDES A FULLY CONSISTENT READING OF THESE SAME STATEMENTS. I CONCLUDE THAT THE GENERATIVE VIEW MORE ADEQUATELY REPRESENTS DESCARTES' INTENTIONS.

Descartes' procedure in "Meditation II" must be brought into line with his claim that "we must never ask about the existence of anything until we first understand its essence." And Descartes' "Meditation III" claim that he is aware of his mind's power to cause ideas must be grounded in a prior discovery of this power. Both demands are met by reading "Meditation II" as a progressive clarification of the nature of mind, with the investigation of the wax providing the discovery (...) of the mind's generative power. This process of discovery also provides the meanings of "thinking" and "existing" -- as "causing ideas" and "exercising causal power", respectively. Thus the discovery of the mind's nature also grounds the cogito. I provide a close reading of the wax investigation which supports this view. (shrink)

This paper examines the significance of Anscombe’s decision to substitute the example of Excalibur for that of Nothung in section 39 of the PhilosophicalInvestigations. It argues that the substitution significantly alters the mythological background to Wittgenstein’s discussion of naming and its philosophical subliming, in which the Theatetus conception of identity, composition, and decomposition is contrasted with that of Wagner’s Ring; for Arthurian legend conceives of these matters differently again. The broader purpose of the paper is to demonstrate that these (...) mythological worlds are not dispensable ornaments to Wittgenstein’s philosophical explorations, but rather internal to his way of guiding and reorienting our reflections on proper names, personal identity, and selfhood.

The paper analyzes the incompatibility of Evolutionary Epistemology of Theories (EET) with Charles Darwin’s theory of evolution. The argument consists of four parts, each addressing a specific problem with EET and offering examples. Firstly, advocates of EET frequently misapply Darwin’s theory by asserting that evolution is teleological, which is at odds with Darwinism. Secondly, the “universal Darwinism” underlying EET is inconsistent with the relativism present in Darwin’s theory. Thirdly, because of the relativistic character of Darwin’s theory, philosophies that appeal to (...) it need to provide additional justification for using Darwin’s ideas outside of biology, which EET fails to do. Finally, the paper demonstrates that the Darwinocentric historiography proposed by EET underappreciates neo-Lamarckism, whose model of evolution is closer to that used in EET. (shrink)

A major contribution to Descartes studies, this book provides a panorama of cutting-edge scholarship ranging widely over Descartes's own primary concerns: metaphysics, physics, and its applications. It is at once a tool for scholars and--steering clear of technical Cartesian science--an accessible resource that will delight nonspecialists. The contributors include Edwin Curley, Willis Doney, Alan Gabbey, Daniel Garber, Marjorie Grene, Gary Hatfield, Marleen Rozemond, John Schuster, Dennis Sepper, Stephen Voss, Stephen Wagner, Margaret Welson, Jean Marie Beyssade, Michelle Beyssade, (...) Michel Henry, Evert van Leeuwen, Jean-Luc Marion, Genevieve Rodis-Lewis, and Jean-Pierre Seris. Combining new textual sensitivity with attentiveness to history, they represent the best established scholars and most exciting new voices, including both English speaking and newly-translated writers. Part I examines the foundations of Descartes's philosophy: Cartesian certainty; the phenomenology of the cogito and its modulations in the passions; and the defensibility and comprehensibility of the Cartesian God. The second part examines Descartes's groundbreaking metaphysics: mind's distinctness from and interaction with body; imagination; perception; and language. Part III examines Cartesian science: the revolutionary rhetoric of the Rules and the Discourse; the metaphysical foundations of physics; the interplay of rationalism and empiricism; the mechanics and human biology that flow from Descartes's physics.

This is a unique book, drawing together the profound insights of Eastern philosophy (Advaita Vedanta), Western depth-psychology (Jungian), and spirituality (Ignatian) as applied to decision-making. Mention is made of Plato, C. G. Jung, Ira Progoff, Viktor Frankl, and Bernard Lonergan, amongst others. Powerful and practical tools and techniques for making wise decisions are offered. There are sections on Descartes's famous square, the ego and the Self, the I Ching and synchronicity, archetypes, neuroscience and the triune brain, biases and blind spots (...) which can derail decision-making, together with chapters on creativity, the "aha" experience, and the Enneagram with its nine decision-making styles. Dr. Costello is at pains to point out that heart (emotions), head (reason), and hands (action/doing) must be integrated before effective decision-making can take place and bear fruition. (shrink)

Although it can hardly be denied that BT is—as its first paragraph declares—centrally concerned to advance the science of aesthetics by coming to grips with the essence of Attic tragedy, it should not be forgotten that its author also characterizes the book (in its foreword) as being in constant conversation with Richard Wagner, and hence as a continuation of their joint struggle properly to grasp the true purpose and full value of Wagnerian opera, understood as aspiring to the status (...) of a Gesamtkunstwerk. One might say that BT is an attempt to make sense of the Wagner circle’s habit of referring to their leader as Aeschylus—to ground Nietzsche’s intuition that the work of both men embodies an enigmatic sublimity ..

The red tape and delays around research ethics and governance approvals frequently frustrate researchers yet, as the lesser of two evils, are largely accepted as unavoidable. Here we quantify aspects of the research ethics and governance approvals for one interview- and questionnaire-based study conducted in England which used the National Health Service procedures and the electronic Integrated Research Application System. We demonstrate the enormous impact of existing approvals processes on costs of studies, including opportunity costs to focus on the substantive (...) research, and suggest directions for radical system change. We have recorded 491 exchanges with 89 individuals involved in research ethics and governance approvals, generating 193 pages of email text excluding attachments. These are conservative estimates. The exchanges were conducted outside IRAS, expected to be the platform where all necessary documents are provided and questions addressed. Importantly, the figures exclude the actual work of preparing the ethics documentation. We propose six areas of work to enable system change: 1. Support the development of a broad range of customised research ethics and governance templates to complement generic, typically clinical trials orientated, ones; 2. Develop more sophisticated and flexible frameworks for study classification; 3. Link with associated processes for assessment, feedback, monitoring and reporting, such as ones involving funders and patient and public involvement groups; 4. Invest in a new generation IT infrastructure; 5. Enhance system capacity through increasing online reviewer participation and training; and 6. Encourage researchers to quantify the approvals processes for their studies. Ethics and governance approvals are burdensome for historical reasons and not because of the nature of the task. There are many opportunities to improve their efficiency and analytic depth in an age of innovation, increased connectivity and distributed working. If we continue to work under current systems, we are perpetuating, paradoxically, an unethical system of research approvals by virtue of its wastefulness and impoverished ethical debate. (shrink)

This paper examines the way Charles Darwin applied his domestic breeding analogy to the practical workings of species evolution: that application, it is argued, centered on Darwin's distinction between methodical and unconscious selection. Methodical selection, which entailed pairing particular individuals for mating purposes, represented conditions of strict geographic isolation, obviously useful for species multiplication (speciation). By contrast, unconscious selection represented an open landmass with a large breeding population. Yet Darwin held that this latter scenario, which often would include multiple ecological (...) subdistricts and thus partial isolation, was better suited for speciation than were isolated conditions. At the same time, many passages in Darwin's writings that apparently portrayed phyletic evolution exclusively (these including references to unconscious selection), actually applied to speciation as well, for phyletic change in a single district could constitute a local manifestation of a larger common-descent pattern. This generic use of "phyletic" change was reflected in Darwin's deployment of the unconscious selection analogy in his published writings as well as in his dispute with Moritz Wagner over the necessity of geographic isolation for speciation. We can thus understand Darwin's otherwise puzzling declaration in The Origin of Species that unconscious selection was 'more important' than the methodical approach. (shrink)

In Squaring the Circle in Descartes’ Meditations, Stephen Wagner aims to show that Descartes’ project in the Meditations is best understood as a ‘strong validation of reason’ i.e., as proving in a non-circular way that human reason is a reliable, truth-conducive faculty. For such an enterprise to qualify as a ‘strong’ validation, Wagner contends, skeptical doubt must be given its strongest force. The most stringent doubt available in the Meditations is the deceiving God. To rule out the (...) possibility that an omnipotent God created humans so that their best functioning cognitive faculties provide misleading information about what the world is like, Descartes must prove that a non-deceiving God exists. Furthermore, only a non-circular proof will count as a ‘validation.’ Wagner spells out the requirements of non-circularity as involving a proof for God’s existence that is not deductive, does not simply achieve a clear and distinct perception of God’s existence, and proceeds on the basis of perceptions that remain true even when the reasons underlying them are not attended to any longer by the meditator.

This volume addresses the interdependencies between visual technologies and epistemology with regard to our perception of the medical body. It explores the relationships between the imagination, the body, and concrete forms of visual representations: Ranging from the Renaissance paradigm of anatomy, to Foucault's "birth of the clinic" and the institutionalised construction of a "medical gaze"; from "visual" archives of madness, psychiatric art collections, the politicisation and economisation of the body, to the post-human in mass media representations. Contributions to this volume (...) investigate medical bodies as historical, technological, and political constructs, constituted where knowledge formation and visual cultures intersect.

Stephen Tracy's neat demonstration that IG I3 35—authorizing the building of a temple and appointment of a priestess for Athena Nike—was cut by the man responsible for the Promachos accounts at first seemed decisive for the traditional c. 448 B.C. against my radical down-dating. Ira Mark then argued that this decree provided for the naiskos and altar of his Stage III in the 440s: the marble temple belonged to Stage IV over twenty years later. Despite these two powerful interventions (...) the matter is not closed. David Gill has, I fancy, convincingly refuted Mark on archaeological and architectural grounds. And there is still more to be said from the epigraphic angle. IG I 36, cut on the back of the stele, looks like a delayed rider to 35. But just how delayed was it? It arranged for the regular payment of the priestess's salary by the kolakretai in office in the month Thargelion. On the traditional view the gap would be close to a quarter of a century, since 36 is firmly dated 424/3 B.C. This is quite extraordinary, though reasons have been found for it. More serious perhaps is some neglected epigraphic evidence. We have eighteen other examples in fifth-century Attic epigraphy where decrees are followed on the same stone by other texts; but virtually all the gaps are short, never more than a few years. The relevant texts are IG I 4, 11/12, 41, 42/43, 52 A–B, 59, 61, 66, 68, 71, 72, 73, 89, 93, 101, 127/II1, 156, 1454. It is true that 42/43 are dated c. 445–442 and c. 435–427 B.C. in IG I, but this is quite arbitrary. (shrink)

There is at this point no shortage of testimonials regarding the practice of philosophy for children. In addition, there have been a number of studies which give further support to the claim that philosophy for children is a valuable classroom practice. The idea that pre-college instruction in philosophy is beneficial is no longer in doubt, nor is there a significant lack of materials for use in philosophy for children programs. From Lewis Carroll to Matthew Lipman authors constructed texts that go (...) far in engaging children's philosophical inclinations. If there is any weakness in the practice of philosophy for children it is usually found in the individual classroom. (shrink)

This article addresses a number of phenomena in the field of digital communication - disinformation, infodemics and conspiracy mania - that promote indifference regarding the distinction between truth and lies, fact and fiction, opinion and knowledge. They have thus decisively altered users' patterns of rationality and common sense and contributed to the rise of anti-democratic and anti-scientific positions. To address this complex problem, a systemic approach is provided that considers these phenomena to be factors that disturb the ethical-epistemic equilibrium between (...) uncertainty, trust and responsibility. After identifying a set of dynamics generated by these disruptive factors, three aspects are explored in depth: the polarisation and lack of a deliberative culture, the necessary correction of the social image of scientific practice, and the impact of the post-truth discourse. The article concludes with reflections on redefining the three key concepts of uncertainty, trust and responsibility in light of the demands of the digital sphere. (shrink)

Since the heyday of ordinary language philosophy, Anglophone epistemologists have devoted a great deal of attention to the English word ‘know’ and to English sentences used to attribute knowledge. Even today, many epistemologists, including contextualists and subject-sensitive invariantists are concerned with the truth conditions of “S knows that p,” or the proposition it expresses. In all of this literature, the method of cases is used, where a situation is described in English, and then philosophers judge whether it is true that (...) S knows that p, or whether saying “S knows that p” is false, deviant, etc. in that situation. However, English is just one of over 6000 languages spoken around the world, and is the native language of less than 6% of the world’s population. When Western epistemology first emerged, in ancient Greece, English did not even exist. So why should we think that facts about the English word “know,” the concept it expresses, or subtle semantic properties of “S knows that p” have important implications for epistemology? Are the properties of the English word “know” and the English sentence ‘S knows that p’ shared by their translations in most or all languages? If that turned out to be true, it would be a remarkable fact that cries out for an explanation. But if it turned out to be false, what are the implications for epistemology? Should epistemologists study knowledge attributions in languages other than English with the same diligence they have shown for the study of English knowledge attributions? If not, why not? In what ways do the concepts expressed by ‘know’ and its counterparts in different languages differ? And what should epistemologists make of all this? (shrink)

When young children first begin to ask 'why?' they embark on a journey with no final destination. The need to make sense of the world as a whole is an ultimate curiosity that lies at the root of all human religions. It has, in many cultures, shaped and motivated a more down to earth scientific interest in the physical world, which could therefore be described as penultimate curiosity. These two manifestations of curiosity have a history of connection that goes back (...) deep into the human past. Tracing that history all the way from cave painting to quantum physics, this book sets out to explain the nature of the long entanglement between religion and science: the ultimate and the penultimate curiosity.

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 122.1 (2001) 87-106 [Access article in PDF] Homo Fandi Dulcissimus: The Role of Favorinus in the Attic Nights of Aulus Gellius Stephen M. Beall ONE OF THE INDIRECT BENEFITS of reading the Attic Nights of Aulus Gellius is that he offers us a glimpse of the "smart set" of Antonine Rome. Many chapters are cast as anecdotes featuring Gellius' mentors and acquaintances, among whom (...) he counted such illustrious figures as Herodes Atticus, Marcus Fronto, and the grammarian known as Domitius "the Insane." But the "star" of the work is clearly Favorinus of Arles, a flamboyant orator who described his life in three paradoxes: he was a native of Gaul who spoke Greek, a eunuch who was accused of adultery, 1 and a citizen who quarreled with an emperor and lived (Philostratus, VS 489). To Gellius, he was "Favorinus noster," and the twenty-seven anecdotes involving him indicate that the two were on fairly intimate terms. 2We are left to wonder, however, how someone as eccentric as Favorinus should have become the special friend and mentor of a "fairly conservative, practically minded Roman" such as Gellius. 3 Perhaps, following Polemo, we can attribute the attraction to Favorinus' skill in the black arts. 4 It is more likely, however, that he possessed qualities that could be adapted to Gellius' intellectual program but which have not been fully elucidated by scholarship. 5 These can best be expounded, I believe, as three additional paradoxes: Favorinus was a polymath who passed for a philosopher, a philhellene who studied Roman culture, and [End Page 87] a Greek "Asianist" with ties to Latin archaism. All three paradoxes, as we shall see, relate to thematic issues in the Attic Nights and may help us to account for the paradoxical nature of the work as a whole. 1. Favorinus: The Miscellaneous Philosopher Favorinus' professional status was open to question even in antiquity. Philostratus describes him as a "philosopher" who "was called a sophist" by dint of his charm as a speaker (VS 489). The Suda puts the case less charitably, saying that "he was full of philosophy, but more devoted to rhetoric" (Phi 4). Lucian's Demonax found him too effeminate in style and appearance to wear the mantle (Demonax 12-13). When Favorinus claimed a philosopher's exemption from public service, the emperor Hadrian was prepared to rule against him (Philostratus, VS 490). Favorinus averted this disaster by accepting the priesthood in question, claiming that he had been advised to do so in a dream.The question of Favorinus' calling is further complicated by the mixed character of his published work, little of which survives. 6 He wrote treatises on philosophical skepticism, including the celebrated Pyrrhonian Tropes (Phil. VS 491; cf. Gellius, 11.5.5). 7 He did not, however, restrict himself to writing of a technical kind. He also produced two miscellanies, the Memorabilia and Omnigena Historia, which seem to have combined philosophical anecdotes with other sorts of trivia, including etymologies and wonder tales. 8 His oratorical remains likewise indicate a versatile and playful intellect. Two speeches preserved in the corpus of Dio Chrysostom (37, 64), and a third on a recently discovered papyrus, are notable for their witty use of stock themes and exempla. He declaimed on "absurd" themes, such as the virtues of Thersites and the advantages of the quartan fever (Gellius, NA 17.12). Indeed, he was so adept at sophistic role-playing that Gellius could not tell when he was speaking in earnest (14.1.2). Philostratus reports that he drew crowds with a highly musical style of speaking, at times almost like singing, which won applause even from people who could not understand Greek (VS 491).In the anecdotes of the Attic Nights, we find a similarly ambiguous [End Page 88] characterization. Although Gellius regularly honors his mentor with the epithet philosophus, 9 he praises him chiefly for the "sweetness of his diction," which, he says, held him captive for entire days (16.3.1; cf. 14.1.32). Elsewhere he lauds him... (shrink)

Davidson’s remark is fairly conventional stuff in contemporary philosophy, but the argument that informs it is elusive. Is this a kind of unformulated transcendental argument, which amounts to the claim that the ‘sharing’ of ‘language,’ in some unspecified sense of these terms, is a condition of the possibility of ‘communication’ in some unspecified sense of this term? Or is it a kind of inference to the best explanation in which there are no real alternativesan inference, so to speak, to the (...) only explanation? There are good reasons to be suspicious of arguments of this form. Yet this general picture, of some sort of shared stuff at the basis of language, is highly appealing, and so is its extension to practices generally. The claim that there is some class of things that could not happen, were it not for the existence of some sort of shared practices, is a commonplace, despite, and perhaps because of its vagueness.

This article critiques the idea that, by establishing a general framework within which research must be conducted, philosophical argument can ‘take the lead’ in relation to research. It develops Holmwood’s work in this area by examining the ontological arguments put forward by critical realists, which attempt to establish the fundamental characteristics of the social realm prior to the production of empirically successful research in that realm. The article draws on a contrast with ontological argument in the natural sciences to demonstrate (...) the illegitimacy of this manoeuvre, showing that ontological claims can be given some justification, but only when they are derived from research that is widely held to be empirically successful. Realist ontological claims in the social sciences do not have this basis, and it is argued that Bhaskar’s alternative mode of justification for these claims is unconvincing. Archer’s view is also criticized that critical realist arguments should be given a strong regulatory role in relation to research, illustrating the problems with this by critiquing Cruickshank’s ontologically driven analysis of unemployment and the underclass. The article concludes that social scientific research should be conducted without philosophical legislation. (shrink)

We think this is Chomsky's view, and also the view he finds in certain historical figures who participated in debates about innate ideas. Chomsky's contribution to the traditional debate lies in (i) his articulation and defense of a detailed nativist program in linguistics, showing _how_ experience plays only a restricted role in a broadly rationalist account of the acquisition of linguistic knowledge, and (ii) the framework this program suggests, given its empirical success, for the more general study of human cognition. (...) Linguistics -- where this includes not just the study of expressions and their properties, but also related work in psycholinguistics -- provides a case study of how to investigate _which aspects of_ human thought are due largely to human nature. Earlier chapters have addressed (i). We'll try to give the flavor of (ii) by discussing some historically important examples, and then by reviewing some recent discoveries, inspired by the Chomskian approach to human psychology, about the properties of linguistic expressions that have a direct bearing on logical reasoning. .
