This book offers a new interpretation of Hermann von Helmholtz's work on the epistemology of geometry. A detailed analysis of the philosophical arguments of Helmholtz's Erhaltung der Kraft shows that he took physical theories to be constrained by a regulative ideal. They must render nature "completely comprehensible", which implies that all physical magnitudes must be relations among empirically given phenomena. This conviction eventually forced Helmholtz to explain how geometry itself could be so construed. Hyder shows how Helmholtz answered this (...) question by drawing on the theory of magnitudes developed in his research on the colour-space. He argues against the dominant interpretation of Helmholtz's work by suggesting that for the latter, it is less the inductive character of geometry that makes it empirical, and rather the regulative requirement that the system of natural science be empirically closed.

ArgumentHermann von Helmholtz’s distinction between “pure intuitive” and “physical” geometry must be counted as the most influential of his many contributions to the philosophy of science. In a series of papers from the 1860s and 70s, Helmholtz argued against Kant’s claim that our knowledge of Euclidean geometry was an a priori condition for empirical knowledge. He claimed that geometrical propositions could be meaningful only if they were taken to concern the behaviors of physical bodies used in measurement, from which it (...) followed that it was posterior to our acquaintance with this behavior. This paper argues that Helmholtz’s understanding of geometry was fundamentally shaped by his work in sense-physiology, above all on the continuum of colors. For in the course of that research, Helmholtz was forced to realize that the color-space had no inherent metrical structure. The latter was a product of axiomatic definitions of color-addition and the empirical results of such additions. Helmholtz’s development of these views is explained with detailed reference to the competing work of the mathematician Hermann Grassmann and that of the young James Clerk Maxwell. It is this separation between 1) essential properties of a continuum, 2) supplementary axioms concerning distance-measurement, and 3) the behaviors of the physical apparatus used to realize the axioms, which is definitive of Helmholtz’s arguments concerning geometry.

I analyze the two main theses of Helmholtz's "The Applicability of the Axioms to the Physical World," in which he argued that the axioms of Euclidean geometry are not, as his neo-Kantian opponents had argued, binding on any experience of the external world. This required two argumentative steps: 1) a new account of the structure of our representations which was consistent both with the experience of our (for him) Euclidean world and with experience of a non-Euclidean one, and 2) a (...) demonstration of why geometric propositions are essentially connected to material and temporal aspects of experience. The effect of Helmholtz's discussion is to throw into relief an intermediate category of metrological objects--objects which are required for the properly theoretical activity of doing physical science (in this sense, a priori requirements for doing science), all while being recognizably contingent aspects of experience.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.3 (2003) 421-422 [Access article in PDF] Konstantin Pollok. Kants Metaphysische Anfangsgründe der Naturwissenschaft. Ein kritischer Kommentar. Hamburg: Felix Meiner Verlag, 2001. Pp. x + 546. Cloth, € 98.00.Kant's Metaphysical Foundations of Natural Science (MFNS) was published in 1786, one year after his Groundwork of the Metaphysics of Morals, and thus also falling in the period between the two editions of the Critique (...) of Pure Reason. Long assigned a tertiary status within the corpus, the MFNShas for several reasons been the subject of renewed scholarly attention in the past two decades. Attempts to trace the origins of analytic philosophy beyond the work of the logicists and the Vienna Circle have focussed attention on neo-Kantian "scientific epistemologists" such as Helmholtz, Hertz, and their contemporaries, for whom Kant's philosophy of science formed a common point of departure. This more general concern is complemented by Kant scholars' increasing interest in his philosophies of mathematics and the sciences. Finally, there is greater appreciation of the importance of the Metaphysical Foundations for our understanding of Kant's revisions to the first Critique, for instance his emphasis in the B-edition on the necessity of external intuition to the "objective reality" of the categories.Earlier neglect of the MFNS was not merely the product of indifference to these issues, for it is an obscure book, even for Kant. In extending the transcendental metaphysics of the Critique into the domain of empirical science, Kant demands of his reader a thorough grasp of the critical philosophy. To complicate matters, the larger part of the text involves a detailed analysis of classical scientific concepts taken from the Leibnizian and Newtonian traditions. Kant often draws on his earlier writings on the natural sciences, such as the Physical Monadology, and either modifies or, in the case of pre-critical sources, inverts these to fit their new context. The book often seems to be little more than a rationalist deduction of the key concepts of Newtonian physics, at least as Kant understood them. In order to extract philosophically interesting arguments from this mixture of physical science and transcendental philosophy, one must have a firm grasp of the background in the history of science and of Kant's oeuvre as a whole. To date, there have been only two full-length studies (by Addickes and Plaass) devoted to this short work, and neither of them attempted to cover it as a whole. Konstantin Pollok's commentary of the MFNSwill therefore fill an important gap in the secondary literature. [End Page 421]Pollok's Critical Commentary, which is written in a clear anduncomplicated academic German, steers a middle course between textual analysis and criticism. The author accords each major division of the book (the Preface, Phoronomy, Dynamics, Mechanics, and Phenomenology) its own chapter, and then follows the argumentative lines of these closely. But Pollok's text does not mirror Kant's "mathematical" sub-division of the MFNSinto axioms, theses, and scholia. These are often grouped together and commented on as a single argumentative whole, which is keyed with the title of the main sub-division. The body text of the commentary consists of textual exegesis, quotations, and references to historical sources, as well as to the larger context of Kant's philosophy. The lengthy footnotes address discussions and controversies in recent secondary literature, as well as Pollok's evaluation of these. He quotes both primary and secondary sources at length, thereby freeing the reader from the bother of tracking down quotations in order to grasp what is at issue. This aid is, however, counterbalanced by his legitimate decision to quote all sources in the original language, with the exception of those available to Kant only in translation.Critical discussion is strictly confined to the conceptual context of Kant's time, in that the significance of Kant's arguments for later developments in the philosophy of science, and their status from the standpoint of such later developments are not addressed. But this decision still leaves open significant interpretative play: one can approach the... (shrink)

The dissertation analyzes the theory of "logical space" developed by Ludwig Wittgenstein in his Tractatus Logico-Philosophicus, I show how this idea represents a development of arguments first put forward by Hermann von Helmholtz, the physicist and physiologist. Helmholtz--instead of honouring Kant's distinction between on the one hand time and space, and, on the other, empirical qualia --stretched the Kantian spatial manifold to cover the other qualia as well: the qualia are also organized in manifolds; and this new, extended manifold is (...) the "space" of all possible human experience. He explained this a priori mesh as being a consequence of the physiological constitution of our bodies, and the physical constitution of the world in which they are situated. The subject is enclosed in an inner world whose structure is the network of possible sensation; outside of her is a world of unknown complexity; and separating the two is what Heinrich Hertz called the "no-man's-land" of sense-physiology, a border zone regulating all traffic between the two realms, common to both, yet proper to neither. ;Wittgenstein, in his Tractatus, adapted the picture-theories of Helmholtz and Hertz to his analysis of logic. He too was confronted with the problem of defining a field of possible experience, of possible facts: his analysis of Russell's and Frege's logical theories had led him to the conclusion that the fundamental properties of logic could not be accounted for without assuming such an a priori space. Thus he assimilated Russell's types to the dimensions of a manifold, the elements of which were his Sachverhalte, or elementary facts. The truth-functions of our logic are defined on top of this space: it is the basis on which all symbolic systems, including those of the natural sciences, are erected. (shrink)

This work is for scholars, researchers and students in history and philosophy of science focusing on Logical Empiricism and analytic philosophy (of science). It provides historical and systematic research and deals with the influence and impact of the Vienna Circle/Logical Empiricism on today's philosophy of science. It also explores the intellectual context of this scientific philosophy and focuses on main figures and peripheral adherents.

: This paper discusses the origins of two key notions in Foucault's work up to and including The Archaeology of Knowledge. The first of these notions is the notion of "archaeology" itself, a form of historical investigation of knowledge that is distinguished from the mere history of ideas in part by its unearthing what Foucault calls "historical a prioris". Both notions, I argue, are derived from Husserlian phenomenology. But both are modified by Foucault in the light of Jean Cavaillès's critique (...) of Husserl's theory of science. On Husserl's view, we demand that propositions holding of scientific objects be intersubjective and invariant, but this demand conflicts with our immediate experience, which is essentially bound to a subject's perspective. Thus the mathematical and physical sciences must utilise formal languages to fix these truths independently of the thoughts of a particular subject. This necessary procedure leads to the sedimentation of these formal systems: we forget their source in the concrete experiences of individuals, and use them as purely technical means. The technique of reactivating the intentional acts in which sedimented formal systems originated is thus, in Fink's terminology, an archaeological method. Foucault and Cavaillès retain the general outlines of this archaeology of the sciences, but they reject its appeal to conscious acts of meaning, to what Cavaillès calls "the philosophy of consciousness". I conclude by discussing the implicit difficulties in the "linguistic transcendentalism" proposed as an alternative by these French critics of Husserl. (shrink)

The theory of space-time developed in Kant’s Critique of Pure Reason and his Metaphysical Foundations of Natural Science is connected to Leonhard Euler’s proof of invariance under Galilean transformations in the “On Motion in General” of the latter’s 1736 Analytical Mechanics. It is argued that Kant, by using the Principle of Relativity that is the output of Euler’s proof as an input to his own proof of the kinematic parallelogram law, makes essential use of absolute simultaneity. This is why, in (...) the Transcendental Aesthetic, he observes that “our theory of time explains as much a priori knowledge as the general theory of motion displays.” In conclusion, it is shown that the same proof-method, under a different definition of simultaneity, leads to the parallelogram law of the “Kinematic Part” of Einstein’s 1905 “On the Electrodynamics of Moving Bodies”.

This book is a collection of essays on Husserl's _Crisis of European Sciences_ by leading philosophers of science and scholars of Husserl. Published and ignored under the Nazi dictatorship, Husserl's last work has never received the attention its author's prominence demands. In the _Crisis_, Husserl considers the gap that has grown between the "life-world" of everyday human experience and the world of mathematical science. He argues that the two have become disconnected because we misunderstand our own scientific past—we confuse mathematical (...) idealities with concrete reality and thereby undermine the validity of our immediate experience. The philosopher's foundational work in the theory of intentionality is relevant to contemporary discussions of _qualia_, naive science, and the fact-value distinction. The scholars included in this volume consider Husserl's diagnosis of this "crisis" and his proposed solution. Topics addressed include Husserl's late philosophy, the relation between scientific and everyday objects and "worlds," the history of Greek and Galilean science, the philosophy of history, and Husserl's influence on Foucault.

Dieter Henrich ‘s “Notion of a Deduction” (1989), opened up approaches to both Deductions in terms of legal as opposed to syllogistic reasoning. Since the CpR is shot through with juridical metaphors and analogies, many points of connection suggest themselves. In this paper, I extend and modify Henrich’s approach, in order to extract a particular logic of evidence. I argue that the three syntheses of the A-Deduction correspond to parts of a deductive procedure, and that their names have been chosen (...) to indicate this connection to the reader. Nonetheless, the principal aim of the paper is not to develop and defend these historiographical claims, but to explicate the structure of the logic of evidence in question and link it to Kant’s intended refutation of Hume. Since the procedures Kant describes are part of the law of evidence of many nations and are equally well at work in contemporary information-theory, a precise reconstruction can map directly onto contemporary problems in philosophy, physics, and informatics, without any loss of historical accuracy.

A translation of the Introduction to Hermann Cohen's 1883 work The Principle of the Infinitesimal Method and Its History.

Parmenides’ Poem on Nature contains a proof that the world could not have come into being in time, because no explanation could be given for why it would do so at a given time. This same proof reappears in the Leibniz-Clarke Correspondence, where it is directed against Newtonian absolute time. Newtonians, Leibniz explains, believe that time is homogeneous and absolute, but this makes it inexplicable how God could have chosen to create the world on a given day. Similarly, in his (...) correspondence with Schrödinger in the 1930s, Einstein suggests that certain quantum mechanical occurrences, such as the spontaneous decay of a radioactive atom, are absurd, because they cannot be assigned a definite location in time. In Schrödinger’s version of Einstein’s argument, we must say that the cat dies twice: first, inside the box; yet, second, when we open the box. But both accounts cannot be true. Since each of the authors discussed was aware of the approach of his predecessors, they share a structure. In this article, I develop a unified account of all three. (shrink)

In this lengthy book, Daniel Sutherland proposes to rectify our long neglect of Kant's theory of mathematics by means of both historical and systematic analyses. This is a worthy undertaking, since the scope and significance of that theory were lost from view during the twentieth century.

Background: Increasing collaboration between industrialised and developing countries in human research studies has led to concerns regarding the potential exploitation of resource deprived countries. This study, commissioned by the former National Bioethics Advisory Commission of the United States, surveyed developing country researchers about their concerns and opinions regarding ethical review processes and the performance of developing country and US international review boards .Methods: Contact lists from four international organisations were used to identify and survey 670 health researchers in developing countries. (...) A questionnaire with 169 questions explored issues of IRB review, informed consent, and recommendations.Results: The majority of the developing country researchers were middle aged males who were physicians and were employed by educational institutions, carrying out research on part time basis. Forty four percent of the respondents reported that their studies were not reviewed by a developing country IRB or Ministry of Health and one third of these studies were funded by the US. During the review process issues such as the need for local language consent forms and letters for approval, and confidentiality protection of participants were raised by US IRBs in significantly higher proportions than by host country IRBs.Conclusion: This survey indicates the need for the ethical review of collaborative research in both US and host countries. It also reflects a desire for focused capacity development in supporting ethical review of research. (shrink)

In this book, which thoroughly revises and greatly expands his classic work Sameness and Substance, David Wiggins retrieves and refurbishes in the light of twentieth-century logic and logical theory certain conceptions of identity, of substance and of persistence through change that philosophy inherits from its past. In this new version, he vindicates the absoluteness, necessity, determinateness and all or nothing character of identity against rival conceptions. He defends a form of essentialism that he calls individuative essentialism, and then a (...) form of realism that he calls conceptualist realism. In a final chapter he advocates a human being-based conception of the identity and individuation of persons, arguing that any satisfactory account of personal memory must make reference to the life of the rememberer himself. This important book will appeal to a wide range of readers in metaphysics, philosophical logic, and analytic philosophy. (shrink)

Lipsey and Lancaster's "general theory of second best" is widely thought to have significant implications for applied theorizing about the institutions and policies that most effectively implement abstract normative principles. It is also widely thought to have little significance for theorizing about which abstract normative principles we ought to implement. Contrary to this conventional wisdom, I show how the second-best theorem can be extended to myriad domains beyond applied normative theorizing, and in particular to more abstract theorizing about the normative (...) principles we should aim to implement. I start by separating the mathematical model used to prove the second-best theorem from its familiar economic interpretation. I then develop an alternative normative-theoretic interpretation of the model, which yields a novel second best theorem for idealistic normative theory. My method for developing this interpretation provides a template for developing additional interpretations that can extend the reach of the second-best theorem beyond normative theoretical domains. I also show how, within any domain, the implications of the second-best theorem are more specific than is typically thought. I conclude with some brief remarks on the value of mathematical models for conceptual exploration. (shrink)

Askeri bir darbeyle iktidara gelen Cemal Abdülnasır, hükümeti devraldıktan sonra sosyalizmle karışık Arap milliyetçiliği ideolojisini benimsedi. Nasır'ın Arap milliyetçiliğini ulusal sınırların ötesine etkili bir şekilde yayabilmesi için güçlü siyasi propaganda araçlarına sahip olması gerekiyordu. Bu anlamda Nasır döneminde, radyo yayınları ve müzik besteleri çok etkili propaganda araçları olarak ortaya çıktı ve Nasır mali ve maddi kaynaklara önemli yatırımlar yapılmasını teşvik etti. Özellikle de Ümmü Gülsüm'ün ses yeteneği, Nasır'ın Arap milliyetçiliğini yayma çabalarını desteklemede öne çıktı ve Ümmü Gülsüm’ün sesi, bu alanda (...) etkin ve ses yetenekleri kullanılan diğer sanatçıların etkisini geride bıraktı. Bu makale, 1950’ler ve 1960’lar boyunca Nasır’ın Arap milliyetçiliğini Ortadoğu’da yayma noktasında Ümmü Gülsüm'ün sesini ve Arapların Sesi Radyosu’nu yumuşak güç unsuru olarak kullandığını iddia etmektedir. Bu kapsamda çalışma, Ümmü Gülsüm'ün Nasırcı Arap milliyetçiliğinin yayılmasına yaptığı katkının çeşitli boyutlarını beş temel hususa odaklanarak incelemektedir. İlk olarak, yumuşak gücün siyasi idealleri yaymak ve ortak bir kimlik duygusu geliştirmek için bir araç olarak kullanımını araştırmaktadır. İkinci olarak, Nasır tipi milliyetçiliğin ve radyo yayınlarının bu süreçteki rolünü irdelemektedir. Üçüncüsü, radyonun Nasır'ı desteklemek için nasıl bir siyasi propaganda aracı olduğunu araştırmaktadır. Dördüncü olarak, Ümmü Gülsüm'ün Nasırcı Arap milliyetçiliğini teşvik etmedeki araçsal rolünü analiz etmektedir. Son olarak, Ümmü Gülsüm'ün ses yeteneğinin Arap dünyasında Nasırcı milliyetçiliğin yayılması üzerindeki etkisini değerlendirmektedir. (shrink)

Artificial intelligence has historically been conceptualized in anthropomorphic terms. Some algorithms deploy biomimetic designs in a deliberate attempt to effect a sort of digital isomorphism of the human brain. Others leverage more general learning strategies that happen to coincide with popular theories of cognitive science and social epistemology. In this paper, I challenge the anthropomorphic credentials of the neural network algorithm, whose similarities to human cognition I argue are vastly overstated and narrowly construed. I submit that three alternative supervised learning (...) methods—namely lasso penalties, bagging, and boosting—offer subtler, more interesting analogies to human reasoning as both an individual and a social phenomenon. Despite the temptation to fall back on anthropomorphic tropes when discussing AI, however, I conclude that such rhetoric is at best misleading and at worst downright dangerous. The impulse to humanize algorithms is an obstacle to properly conceptualizing the ethical challenges posed by emerging technologies. (shrink)

Obsessive-compulsive disorder (OCD) is a deeply enigmatic psychiatric condition associated with immense suffering worldwide. Efficacious therapies for OCD, like exposure and response prevention (ERP) are sometimes poorly tolerated by patients. As many as 25 percent of patients refuse to initiate ERP mainly because they are too anxious to follow exposure procedures. Accordingly, we proposed a simple and tolerable (immersive yet indirect) low-cost technique for treating OCD that we call “multisensory stimulation therapy.” This method involves contaminating a rubber hand during the (...) so-called “rubber hand illusion” (RHI) in which tactile sensations may be perceived as arising from a fake hand. Notably, Jalal and Ramachandran (2015), showed that such fake hand contamination during the RHI provokes powerful disgust reactions in healthy volunteers. In the current study, we explored the therapeutic potential of this novel approach. OCD patients (n = 29) watched as their hidden real hand was being stroked together with a visible fake hand; either synchronously (inducing the RHI) (i.e., the experimental condition; n = 16) or asynchronously (i.e., the control condition; n = 13). After 5 minutes of tactile stimulation, the rubber hand was contaminated with fake feces, simulating conventional exposure therapy. Intriguingly, results suggested sensory assimilation of contamination sensations into the body image via the RHI: patients undergoing synchronous stimulation did not report greater contamination sensations when the fake hand was initially contaminated relative to asynchronous stroking. But contrary to expectations, they did so after the rubber hand had been contaminated for 5 minutes; as assessed via disgust facial expressions (a secondary outcome) and in vivo exposure (upon discontinuing the illusion). Further to our surprise, synchronous and asynchronous stroking induced an equally vivid and fast emerging illusion, which helps explain why both conditions initially (5 minutes after initiating tactile stimulation) provoked contamination reactions of equal magnitude. This study is the first to suggest heightened malleability of body image in OCD. Importantly, it may pave the way for a tolerable technique for the treatment of OCD—highly suitable for poorly resourced and emergency settings, including low-income and developing countries with minimal access to high-tech solutions like virtual reality.

ABSTRACT In recent years there has been intense debate regarding the level of medical care provided to ‘standard care’ control groups in clinical trials in developing countries, particularly when the research sponsors come from wealthier countries. The debate revolves around the issue of how to define a standard of medical care in a country in which many people are not receiving the best methods of medical care available in other settings. In this paper, we argue that additional dimensions of the (...) standard of care have been hitherto neglected, namely, the structure and efficiency of the national health system. The health system affects locally available medical care in two important ways: first, the system may be structured to provide different levels of care at different sites with referral mechanisms to direct patients to the appropriate level of care. Second, inefficiencies in this system may influence what care is available in a particular locale. As a result of these two factors locally available care cannot be equated with a national ‘standard’. A reasonable approach is to define the national standard of care as the level of care that ought to be delivered under conditions of appropriate and efficient referral in a national system. This standard is the minimum level of care that ought to be provided to a control group. There may be additional moral arguments for higher levels of care in some circumstances. This health system analysis may be helpful to researchers and ethics committees in designing and reviewing research involving standard care control groups in developing country research. (shrink)
