The bucket experiment in Newton’s Principia is quite simple. Nonetheless, physicists as well as philosophers and historians of science are still debating its purpose and success. I present two interpretations found in the literature. According to the first, Newton tries to prove absolute rotation and thus the existence of absolute space. According to the second, he tries to provide a definition of absolute rotation as it is used in his mechanics. Closely connected to this is his rejection of (...) Descartes’ explanation of rotation and of motion in general. I conclude with a short discussion on whether the bucket experiment can be classified as a thought experiment. (shrink)

This chapter contains section titled: Discussion.

Newton’s absolute pace-time view is the basis of his classical mechanics, and his description of relative motion is based on absolute space. However, the existence of this absolute space has been questioned by the academic circles. In order to defend its theoretical foundation, Newton established a famous bucket experiment to prove the existence of absolute space. But his experiment was also questioned, and the experiment is also divided into different opinions. This paper hopes to find the (...) answer to the question from Kantian perspective. (shrink)

Newton's bucket, Einstein's elevator, Schrödinger's cat – these are some of the best-known examples of thought experiments in the natural sciences. But what function do these experiments perform? Are they really experiments at all? Can they help us gain a greater understanding of the natural world? How is it possible that we can learn new things just by thinking? In this revised and updated new edition of his classic text _The Laboratory of the Mind_, James Robert Brown (...) continues to defend apriorism in the physical world. This edition features two new chapters, one on “counter thought experiments” and another on the development of inertial motion. With plenty of illustrations and updated coverage of the debate between Platonic rationalism and classic empiricism, this is a lively and engaging contribution to the field of philosophy of science.

We need only list a few of the well‐known thought experiments to be reminded of their enormous influence and importance in the sciences: Newton's bucket, Maxwell's demon, Einstein's elevator, Heisenberg's gamma‐ray microscope, Schrödinger's cat. The seventeenth century saw some of its most brilliant practitioners in Galileo, Descartes, Newton, and Leibniz. And in our own time, the creation of quantum mechanics and relativity are almost unthinkable without the crucial role played by thought experiments.

A is for Alice and astronomers arguing about acceleration -- B is for Bernard's body-exchange machine -- C is for the Catholic cannibal -- D is for Maxwell's demon -- E is for evolution (and an embarrassing problem with it) -- F is for the forms lost forever to the prisoners of the cave -- G is for Galileo's gravitational balls -- H is for Hume's shades -- I is for the identity of indiscernibles -- J is for Henri Poincaré (...) and alternative geometries -- K is for the Kritik and Kant's kind of thought experiments -- L is for Lucretius' spear -- M is for Mach's motionless chain -- N is for Newton's bucket -- O is for Olbers' paradox -- P is for Parfit's person -- Q is for the questions raised by thought experiments quotidiennes -- R is for the rule-ruled room -- S is for Salvatius' ship, sailing along its own space-time line -- T is for the time-travelling twins -- U is for the universe, and Einstein's attempts to understand it -- V is for the vexed case of the violinist -- W is for Wittgenstein's beetle -- X is for xenophanes and thinking by examples -- Y is for counterfactuals and a backwards approach to history -- Z is for Zeno and the mysteries of infinity.

An explorative contribution to the ongoing discussion of thought experiments. While endorsing the majority view that skepticism about thought experiments is not well justified, in what follows we attempt to show that there is a kind of “bodiliness” missing from current accounts of thought experiments. That is, we suggest a phenomenological addition to the literature. First, we contextualize our claim that the importance of the body in thought experiments has been widely underestimated. Then we discuss David (...) Gooding's work, which contains the only explicit recognition of the importance of the body to understanding thought experiments. Finally, we introduce a phenomenological perspective of the body, which will give us the opportunity to sketch the power and promise of a phenomenological approach to thought experiments. (shrink)

To avoid this blunt and embarrassing alternative seems to be the goal of much recent philosophy--and especially of continental European thought. It becomes apparent at once that these problems cannot be separated from our experience and interpretation of process and duration, of time and change, and of our place within them. It is this consideration, recognized as the very heart of the matter, to which Professor Chaix-Ruy has turned his attention. He finds his central problem to be an ancient (...) and recurring one, and he pays as much attention to Augustine and Pascal as to Bergson and Einstein. There results a panorama of Western thought apprehended from an unusual point of view. The detailed studies included are often fresh and penetrating and the whole argument is of absorbing interest. We may introduce this argument by indicating that at one point, although at one point only, Chaix-Ruy agrees completely with Sartre: the relation of essence to existence in human life is a unique one, quite different from that to be found elsewhere among non-human or sub-human beings. This contrast involves a description of man's relation to time and to change. Human nature is subject to change, or better, man subjects himself to change. "Chez nous l'essence est in fieri". We are reminded of Sartre's "Faire et en faisant se faire," although, as we shall soon see, we need not think of the initiative as lying wholly with our existence, as opposed to our essence. After all, an existence capable of transforming essence must have a structure of its own and a modus operandi. Even the freest choice is "structured." This would seem to be true even if our creative self-realization in some way embraces or contains nonbeing. (shrink)

Now, it seems to me that there is much philosophy written today that does not justify our recognizing such relativism as characteristic of recent thought. In fact, however dominant this way of thinking may appear in other fields, a freshly oriented concern for an absolute may be detected in twentieth-century philosophy. Such concern is for an absolute within rather than behind or above our experience--if you will, for a finite absolute. For such a philosophy, the absolute has not so (...) much "fallen" as settled down, "down to earth" so to speak, where it enters our daily experience. Thus the one of Parmenides whose presence pulverized our common sense is no longer with us, nor are we likely to revive it, but we do hear of an absolute reality present in our conscious lives. Witness Sartre's insistence upon the "absolute character of free involvement" or choice, in contrast with his dismissal of the l'être en soi et pour soi as an impossible ideal. The cogito of Descartes, rather than his perfect being, appears as the historical archetype of our absolute. Thus today the metaphysician is often more concerned with what we way call the quality of man than with the more traditional efforts to discuss cosmic horizons, even though a traditional concern for an authentic reality continues to inspire his work.

In their paper, ‘When are thought experiments poor ones?’ (Peijnenburg and David Atkinson, 2003, Journal of General Philosophy of Science 34, 305-322.), Jeanne Peijnenburg and David Atkinson argue that most, if not all, philosophical thought experiments are “poor” ones with “disastrous consequences” and that they share the property of being poor with some (but not all) scientific thought experiments. Noting that unlike philosophy, the sciences have the resources to avoid the disastrous consequences, Peijnenburg and Atkinson come to (...) the conclusion that the use of thought experiments in science is in general more successful than in philosophy and that instead of concocting more “recherché” thought experiments, philosophy should try to be more empirical. In this comment I will argue that Peijnenburg’s and Atkinson’s view on thought experiments is based on a misleading characterization of both, the dialectical situation in philosophy as well as the history of physics. By giving an adequate account of what the discussion in contemporary philosophy is about, we will arrive at a considerably different evaluation of philosophical thought experiments. For I am convinced that we now find ourselves at an altogether decisive turning point in philosophy, and that we are objectively justified in considering that an end has come to the fruitless conflict of systems. We are already at the present time, in my opinion, in possession of methods which make any such conflict in principle unnecessary. What is now required is their resolute application. (Schlick, ‘The Turning Point in Philosophy’, 1930/1959, p. 54). (shrink)

A characteristic of contemporary analytic philosophy is its ample use of thought experiments. We formulate two features that can lead one to suspect that a given thought experiment is a poor one. Although these features are especially in evidence within the philosophy of mind, they can, surprisingly enough, also be discerned in some celebrated scientific thought experiments. Yet in the latter case the consequences appear to be less disastrous. We conclude that the use of thought (...) experiments is more successful in science than in philosophy. (shrink)

Berkeley’s general tenet about immaterialism is presented and discussed. I examined apart the several theses that concur to the immaterialist theory. After that, the general argument is presented and discussed. In particular, I stress Berkeley’s assumption that a world without matter and a world with matter would be indistinguishable from the point of view of the content of perceptions, natural science. I stress that this assumption depends on a relative account of circular motion, generating the centrifugal forces, as Newton shows (...) in his bucket experiment. In spite of the efforts by Leibniz and Huygens, such a relative account of rotational motion was never presented. So the thesis about the scientific and perceptual identity between worlds with and without matter remains a simple case of wishful thinking in need for a justification. (shrink)

In the Scholium to the Definitions at the beginning of the {\em Principia\/} Newton distinguishes absolute time, space, place and motion from their relative counterparts and attempts to justify they are indeed ontologically distinct in that the absolute quantity cannot be reduced to some particular category of the relative, as Descartes had attempted by defining absolute motion to be relative motion with respect to immediately ambient bodies. Newton's bucket experiment, rather than attempting to show that absolute motion (...) exists, is one of five arguments from the properties, causes and effects of motion that attempts to show that no such program can succeed, and thus that true motion can be adequately analyzed only by invoking immovable places, i.e., the parts of absolute space.

How aggressively should we pursue life-sustaining treatment of the demented patient? This question becomes increasingly important as our population ages and medical technology offers ever more life-prolongation. In Life'sDominion, Ronald Dworkin addresses the issue in the context of an Alzheimer patient who had previously declared the desire to avoid life-sustaining intervention. Dworkin argues for the primacy of what he calls precedent autonomy: In 1995, the HastingsCenterReport carried thoughtful rebuttals by Daniel Callahan and Rebecca Dresser. Much of Callahan's article is devoted (...) to patients who never executed an advance directive, but he states unequivocally that such directives can be overridden, basing much of his argument on the writings of Sanford Kadish. Together, Dresser, Callahan, and Kadish define a clear position opposed to precedent autonomy. (shrink)

At the end of the Scholium Newton includes a long paragraph about two globes revolving around their center of gravity and held together by a tensed cord. It has been interpreted as a thought experiment (Sect. 6.2) meant to show how the properties of true circular motion defined as absolute motion can be determined in a three-dimensional empty universe. I start by showing that this reading of Newton’s example as a bona fide thought experiment is riddled (...) with interpretation problems and that it is less straightforward than so far assumed (Sect. 6.3).

Background: Black, Asian and minority ethnic groups have a high need for organ transplantation but deceased donation is low. This restricts the availability of well-matched organs and results in relatively long waiting times for transplantation, with increased mortality risks. Objective: To identify barriers to organ donor registration and family consent among the BAME population, and to develop and evaluate a training intervention to enhance communication with ethnic minority families and identify impacts on family consent. Methods: Three-phase programme comprising community-based research (...) involving two systematic reviews examining attitudes and barriers to organ donation and effective interventions followed by 22 focus groups with minority ethnic groups; hospital-based research examining staff practices and influences on family consent through ethics discussion groups with staff, a study on intensive care units and interviews with bereaved ethnic minority families; and development and evaluation of a training package to enhance cultural competence among ICU staff. Setting: Community focus group study in eight London boroughs with high prevalence of ethnic minority populations. Hospital studies at five NHS hospital trusts. Participants: Community studies: 228 focus group participants; hospital studies: 35 nurses, 28 clinicians, 19 hospital chaplains, 25 members of local Organ Donation Committees, 17 bereaved family members; and evaluation: 66 health professionals. Data sources: Focus groups with community residents, systematic reviews, qualitative interviews and observation in ICUs, EDGs with ICU staff, bereaved family interviews and questionnaires for trial evaluation. Review methods: Systematic review and narrative synthesis. Results: Community studies: Organ Donor Register – different ethnic/faith and age groups were at varying points on the ‘pathway’ to organ donor registration, with large numbers lacking knowledge and remaining at a pre-contemplation stage. Key attitudinal barriers were uncertainties regarding religious permissibility, bodily concerns, lack of trust in health professionals and little priority given to registration, with the varying significance of these factors varying by ethnicity/faith and age. National campaigns focusing on ethnic minorities have had limited impact, whereas characteristics of effective educational interventions are being conducted in a familiar environment; addressing the groups’ particular concerns; delivery by trained members of the lay community; and providing immediate access to registration. Interventions are also required to target those at specific stages of the donation pathway. Hospital studies: family consent to donation – many ICU staff, especially junior nurses, described a lack of confidence in communication and supporting ethnic minority families, often reflecting differences in emotional expression, faith and cultural beliefs, and language difficulties. The continuing high proportion of family donation discussions that take place without the collaboration of a specialist nurse for organ donation reflected consultants’ views of their own role in family consent to donation, a lack of trust in SNODs and uncertainties surrounding controlled donations after circulatory death. Hospital chaplains differed in their involvement in ICUs, reflecting their availability/employment status, personal interests and the practices of ICU staff. Evaluation: professional development package – a digital versatile disk-based training package was developed to promote confidence and skills in cross-cultural communication. Initial evaluation produced positive feedback and significant affirmative attitudinal change but no significant difference in consent rate over the short follow-up period with requirements for longer-term evaluation. Limitations: Participants in the focus group study were mainly first-generation migrants of manual socioeconomic groups. It was not permitted to identify non-consenting families for interview with data regarding the consent process were therefore limited to consenting families. Conclusions: The research presents guidance for the effective targeting of donation campaigns focusing on minority ethnic groups and provides the first training package in cultural competence in the NHS. Future work: Greater evaluation is required of community interventions in the UK to enhance knowledge of effective practice and analysis of the experiences of non-consenting ethnic minority families.

In reading the Tractatus, one gets the impression that Wittgenstein, having resolved to his satisfaction the problems about language, logic, science, and mathematics, sets these painstakingly articulated findings in a disproportionately skimpy setting. There is a perfunctory ontology at the beginning, which is highly original as well as austere and perplexing; and at the end he hurries even more than usual through ethics, aesthetics and religion—as if the silence was already coming upon him, prematurely. The Notebooks 1914–1916 help a good (...) deal in understanding this skimpy setting. They give little direct indication of the ontological overture, apart from their frequent reiteration that there must be simples of some sort if the sense of expressions is to be determinate, but they give a fuller treatment to the other topics. This is particularly true of the latter half of 1916, when this parcel of topics seems to have become uppermost in Wittgenstein’s mind. Though it is exceedingly difficult to know what to make of what are in effect discarded notes, some of the entries are just too interesting to ignore. I wish to consider what light they throw on his thought at roughly the Tractatus period, and in particular on the ontology that apparently springs up full grown at the beginning of the Tractatus.

How can symbols have meaning for a subject? Foundations of Understanding argues that this is the key question to ask about intentionality, or meaningful thought. It thus offers an alternative to currently popular linguistic models of intentionality, whose inadequacies are examined: the goal should be to explain, not how symbols, mental or otherwise, can refer to or mean states of affairs in the external world, but how they can mean something to us, the users. The essence of intentionality is (...) shown to be conscious understanding, the roots of which lie in experiences of embodiment and goal-directed action. A developmental path is traced from a foundation of conscious understanding in the ability to perform basic actions, through the understanding of the concept of an objective, external world, to the understanding of language and abstract symbols. The work is interdisciplinary: data from the neurosciences and cognitive psychology, and the perspectives of phenomenologists such as Merleau-Ponty, are combined with traditional philosophical analysis. The book includes a chapter on the nature of conscious qualitative experience and its neural correlates. (Series A)". (shrink)

In §69.b of BT Heidegger attempts an existential genetic analysis of science, i.e. a phenomenology of the conceptual process of the constitution of the logical view of science (science seen as theory) starting from the Dasein. It attempts to do so by examining the special intentional-existential modification of (human) being-in-the-world, which is called the "mathematical projection of nature"; that is, by examining that special modification of our being, which places us in the state of experience that presents the world to (...) us as taught by, e.g., Galileo and Newton. The idea he puts forward is that modern mathematical physics and the corresponding experience of the real is the result of the mathematical projection of nature. Modern science, Heidegger says, stands out because it is mathematical. But we cannot get the answer to what this mathematicality consists in from mathematics, because mathematics is only a special manifestation of mathematicality. Here is what Heidegger means by "mathematicality" and, accordingly by "mathematical projection of nature." If one were to let two bodies of different weights fall simultaneously from the top of the tower of Pisa, Heidegger notes, both Galileo and an Aristotelian would see that the two bodies would reach the ground with as little time difference as possible, and not at exactly the same moment. Galileo, however, does something decisive: he claims that under conditions that would be impossible to ensure (if we removed absolutely all resistance to the motion of the bodies), the two bodies would reach the ground absolutely simultaneously. This is not something that he or the Aristotelian sees happening empirically. How, then, does Galileo insist so firmly on his position? How exactly does it happen that he has before him such a view of things? Heidegger's answer is that Galileo is mathematically projecting nature. In his Dialogues Galileo says "I conceive with my mind" (mente concipio) a body thrown to move on an infinitely extending horizontal plane, having eliminated from its path every possible obstacle. Finally, I argue that from the detailed interpretation of Heidegger's points of the mathematical and of the notion of mathematical projection of nature, we can arrive at the conclusions I had arrived at in my doctoral dissertation (2000) as regards the meaning and function of thought experiments in physics as seen from a Husserlian phenomenological point of view as intentional acts. In a nutshell, in thought experiments physics constitutes the special metaphysics (to use the Kantian term) of the primordial ontological region it investigates as well as attempts to make natural sense of the mathematical formalism in cases it proves necessary.

Background: Both the Council for International Organization of Medical Sciences and the Helsinki Declaration emphasize that the potential benefits of research should outweigh potential harms; consequently, some work has been conducted on participants' perception of benefits in therapeutic research. However, there appears to be very little work conducted with participants who have joined non-therapeutic research. This work was done to evaluate participants' perception of benefits in a genetic epidemiological study by examining their perception of the potential benefits of enrollment.Methods: In-depth (...) interviews lasting between 45 and 60 minutes were conducted with a convenient sample of 25 ill patients and 25 healthy accompanying relatives enrolled in a genetic epidemiological study of tuberculosis. Recorded interviews were transcribed and analyzed using content analysis.Results: Participants perceived that research was beneficial and some of the benefits included the generation of new knowledge, finding the cause of diseases, as well as the control, eradication and prevention of disease. Some thought that research was risky whilst others thought that the benefits outweighed the risks.Conclusion: Participants perceived research to be beneficial and most of them thought that, though it was risky, the benefits outweighed the risks. It is our view that researchers need to give serious consideration to participant's perception of benefits in designing their consent forms, to see to the fulfillment of achievable goals. (shrink)

The principal goal of this collection of stimulating essays is clarity about Wittgenstein's work in general and about his conception of clarity in particular. This in-depth, clearly presented study by an internationally recognised scholar of Wittgenstein will be of great interest to philosophers and students of 20th-century thought.

Contrary to the contemporary view that negation is a logical operation that modifies the mere content of a thought or judgment, but not the act of thinking or judging it, Kant maintains that negation is an act of logical apperception through which I exclude a thought or judgment from what ‘I think.’ In this paper, I argue against two interpretations of Kant’s account of logical negation. According to the first, negation is a subjective psychological act of excluding an (...) erroneous judgment. Against this, I will show that for Kant, negation is an operation of logical, not empirical apperception. The second interpretation views logical negation as an objective representation either of a relation of opposition or of non-being. I argue that, on the contrary, the logical function of negation is merely formal, not material, and therefore does not have semantic content. The paper’s final section develops a positive conception of logical negation as a formal function of judging. (shrink)

Some popular views of Ernst Mach cast him as a philosopher-scientist averse to imaginative practices in science. The aim of this analysis is to address the question of whether or not imagination is compatible with Machian philosophy of science. I conclude that imagination is not only compatible, but essential to realizing the aim of science in Mach’s biologico-economical view. I raise the possible objection that my conclusion is undermined by Mach’s criticism of Isaac Newton’s famous “bucket experiment.” I (...) conclude that Mach’s issue lies not with thought experimentation, tout court, but with the improper use of thought experimentation as it relates to the aim of the biologico-economical development of science.

This paper argues for Kantian “universalism,” according to which the subject of empirical cognition is not merely individual, but universal. In the first section, I consider the limitations of Hume’s individualist view of the subject of judgment, which is able to explain how another person exerts power over my judgments, but cannot explain how what she says can challenge or support my judgments. In the second section, I argue that Kant’s universalism accounts for the possibility of rational support both among (...) different judgments in me, and among judgments of different subjects. The third section looks at the consequences of universalism for Kant’s account of testimony. I argue that on Kant’s view, it does not matter whether I learn something from my own experience or from your experience. Testimony thus does not emerge in Kant’s philosophy as a significant topic. In the fourth section, I argue that the enlightenment project of overcoming prejudice and acquiring wisdom makes it imperative that knowledge be not only universally shareable, but also actually shared among members of an epistemic community.

Ernst Mach’s defense of relativist theories of motion in Die Mechanik involves a well-known criticism of Newton’s theory appealing to absolute space, and of Newton’s “bucket” experiment. Sympathetic readers (Norton 1995) and critics (Stein 1967, 1977) agree that there’s a tension in Mach’s view: he allows for some constructed scientific concepts, but not others, and some kinds of reasoning about unobserved phenomena, but not others. Following Banks (2003), I argue that this tension can be interpreted as a constructive (...) one, springing from Mach’s approach to scientific reasoning. Mach’s “economy of science” allows for a principled distinction to be made, between natural and artificial hypothetical reasoning, and Mach defends a division of labor between the sciences in a 1903 paper for The Monist, “Space and Geometry from the Point of View of Physical Inquiry”. That division supports counterfactual reasoning in Mach’s system, something that’s long been denied is possible for him. (shrink)

Rapid changes in academic work environments raise ethical dilemmas in supporting students, implementing policies, and developing professional practice. New teaching technologies require academics to consider community aspects of learning and teaching and impacts on student learning in networked environments. This paper critically reflects on recent experience at a small Australian regional university adapting teaching- notably through on-line environments- to respond to student learning need diversity. Applying Shapiro’s use of the ethics of care, critique, justice and the profession to examine ethical (...) dilemmas associated with increasingly networked and on-line learning, the authors propose that an ethics of community will assist finding practical solutions to ethical dilemmas in curriculum development and delivery. This approach shifts from the individual as moral agent to ethical practice as communal processes. Considering community practices and processes can frame and critique learning and teaching approaches, policies and administration to assist students and staff develop ethical scholarship and professionalism.

[opening paragraph]: It is easy to conceptualize a problem in a way that prevents a solution. If the conceptualization is entrenched in one's culture or profession, it may appear unalterable. But there is so much precedent for the discovery of fruitful reconceptualizations that in the case of most philosophical and scientific puzzles it is probably irrational ever to give up trying. The notion of qualia, understood as phenomenal properties of sensations that can exist as objects of experience for a conscious (...) subject, is too recent in origin and too specialized in usage to warrant concluding that qualia cannot be understood in terms of physical processes. Humphrey offers an analysis of qualitative mental states that purportedly renders them commensurate with brain states, allowing them to be described in terms of the same dimensions. If his attempt is successful the conceptual gap between mind and body could be closed. Is it successful? (shrink)

I consider two arguments about the nature of space that occur in George Berkeley which I think are not sufficiently discussed. The first concerns the phenomenology of space, the second its physics. The first is the "mite" argument and the second concerns Isaac Newton's two thought experiments about absolute space, the "bucket" thought experiment and the "balls" thought experiment. The former suggests that there is no such thing as objective size. Berkeley's position is (...) more confusing on the second experiment, but I argue that the clash between absolutist and relationist spatial intuitions can be reconciled only by an idealist approach to space.

The author considers two arguments concerning the nature of space which occur in Berkeley and which he thinks are not sufficiently discussed. The first one concerns the phenomenology of space, the second the physics of space. The first one is the “mite” argument, while the second draws from Newton’s two thought experiments concerning absolute space: the “bucket” experiment and the “balls” experiment. The author’s aim is to support the idealist approach to space.

O'Brien & Opie hold that phenomenal experience should be identified with “stable patterns of activation” across the brain's neural networks, and that this proposal has the potential for closing the ‘explanatory gap' between mental states and brain processes. I argue that they have too much respect for the conceivability argument and that their proposal already does much to close the explanatory gap, but that a “perspicuous nexus” can in principle never be achieved.

It is a familiar fact in the practice of science that the available observational evidence may not decide between rival hypotheses or theories. For instance, at the time of Copernicus it was widely held that his theory and the Ptolemaic theory did not differ in their predictions in regard to the available astronomical data. This situation can be illustrated by an analogy. Imagine a finite number of dots on a page of paper representing the available evidence. It will always be (...) possible to draw more than one curve connecting the points. How do we decide which curve or theory to adopt? A standard response is to look to some area where the theories make different predictions. We then seek new evidence, perhaps by conducting an experiment, to determine which theory's prediction is correct and opt tentatively for that one. If it is not feasible to gather this evidence, we can be agnostic for the moment on the question of which it is best to adopt. Or, more likely, we will look to factors other than tit with the data to assist us in resolving the matter (see pragmatic factors in theory acceptance). We will call this phenomena weak Underdetermination of theories, or WUT. (shrink)

(Here, incidentally, I follow the book in using the Wade-Giles system.) One can see, comparing the translations, howLiu recast Jāmī's work in Chinese philosophic language, paraphrased some difficult passages, summarized others, and added his own commentaries.Interestingly, Liu eliminated Jāmī's Persian poetry. Murata thinks this is because Liu wanted to focus on the hard ideas; I suspect that it was because Liu realized that Persian prosody and imagery were too far from Chinese poetry to please his audience.Both Wang and Liu belonged to what must have been a rather loose but some-how connected circle of Chinese Islamic scholars. Both, also, almost necessarily used language fairly widespread in Chinese philosophy. Terms such as "emptiness" and "transformation" had many Chinese resonances, some most un-Islamic (Neo Confucian and Buddhist, for instance).Neither Chittick nor Murata give any glosses for key philosophical terms in either source language. Their philosophical and religious provenance, Chinese or Muslim, is correspondingly unclear.What is clear is that Neo-Confucianism had a strong influence on these scholars. Haqiqa "reality" is often translated as li "principle." Pen-jan "root nature" is used for the Arabic compound "essence and attributes." These examples are discussed in the introduction (p. 19). "Annihilation" becomes "conquering" (pp. 148-149). This is strange, because "Annihilation" (fana') is a technical term in Sufism for the disappearance of the self in God; it is an Arabic term, and literally means something like. "passing away." It signifies the forgetting or loss of self, such that only contemplation of the Divine remains. It is as close to the Divine as humans can get since, in Islam, humans cannot be absorbed into Allah (as, in Buddhism, they can be absorbed into Nirvāṇa or the Buddha-nature). "Conquering" seems a rather strange way to express this in Chinese. Perhaps Chinese Muslim readers of the time had developed this specialized sense for it.There are, of course, debatable translations here to contend with (both from Persian and Arabic to Chinese and from Persian and Chinese into English), but it appears that real incommensurability is involved. It was very difficult to use the language of Chinese philosophy in the seventeenth century, influenced as it was by centuries of Neo-Confucian thought, to talk about a radically different religion characterized by an infinitely powerful and wise God, aware of all futures, close to the believer and yet cut off.The inevitable result is to wedge the Arabic and Persian philosophy, so heavily informed by Neoplatonic essentialism and other...

Haartman's analysis of ecstatic experience in early Methodism is contextualized within a brief review of the history of the movement and the theological assertions that underlay these religious behaviors. Wesley emphasized individual, as opposed to institutional religion and affrmed inductive as contrasted with deductive theology. "Sanctification," Wesley's term for personality transformation, is seen as positive ego development rather than regressive splitting of the ego. Maslow's "peak experience" is affrmed as a valid model for analyzing ecstatic behaviors. Methodism no longer emphasizes (...) such forms of religious expression. (shrink)

Many well-known arguments in the philosophy of mind use thought experiments to elicit intuitions about consciousness. Often, these thought experiments include mechanistic explanations of a systems’ behavior. I argue that when we understand a system as a mechanism, we are not likely to understand it as an agent. According to Arico, Fiala, Goldberg, and Nichols’ (2011) AGENCY Model, understanding a system as an agent is necessary for generating the intuition that it is conscious. Thus, if we are presented (...) with a mechanistic description of a system, we will be very unlikely to understand that system as conscious. Many of the thought experiments in the philosophy of mind describe systems mechanistically. I argue that my account of consciousness attributions is preferable to the “Simplicity Intuition” account proposed by David Barnett (2008) because it is more explanatory and more consistent with our intuitions. Still, the same conclusion follows from Barnett’s “Simplicity” account and from my own account: we should reassess the conclusions that have been drawn from many famous thought experiments. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Wittgenstein in Cambridge: Letters and Documents, 1911–1951Newton GarverBrian McGuinness, editor. Wittgenstein in Cambridge: Letters and Documents, 1911–1951. Malden, MA-Oxford: Blackwell Publishing. Pp. vii + 498. Cloth, $134.95.This volume includes nearly everything contained in Cambridge Letters (Blackwell, 1995), supplemented by Wittgenstein’s exchanges with Sraffa (not available in 1995), by correspondence with many of his students, and by various documents pertaining to his status in the University and to the (...) Moral Sciences meetings. Throughout, there are notes by McGuinness that provide details about persons, places, and events mentioned in the texts. Altogether, the volume offers rich rewards for both students of Wittgenstein and those interested in the interplay of the times.Wittgenstein was Austrian to the core, as is evident in his admiration for such distinctly Viennese cultural icons as Nestroy, Grillparzer, Labor, Weininger, and Kraus—none of whom was familiar in the circles within which he moved in Cambridge. In his introduction, however, McGuinness makes clear that Cambridge, not Vienna, was the place where Wittgenstein could work. There were no roots in Cambridge, compared to those in Vienna, but growth, it seems, had to take place away from the roots. During his first stay in Cambridge (1912–14) Wittgenstein established connections with the giants of the time: Russell, Moore, and Keynes, all of whom had been active members of the Apostles, and who therefore put him in touch with the Bloomsbury-flavored younger elite of the University. Although none of these relationships was smooth, they all served in 1929 to ease Wittgenstein’s re-entry into Cambridge.Once back at Cambridge, and back at work in philosophy, Wittgenstein established his own circle, composed of younger scholars who attended his lectures. The only contact from the early period with whom he remained close through the 1930s and ’40s was Moore, although neither Russell nor Keynes disappeared entirely. Moore attended Wittgenstein’s lectures in 1930–33, and the two met regularly whenever Wittgenstein was in Cambridge. Among his peers, the big addition was Piero Sraffa, the Italian economist who was, as McGuinness puts it, first a protegé and then a successor of Keynes. It is difficult to reconstruct the content of the conversations between these two powerful intellects, but the letters and notes included here make it plain that the conversations were intense and had continuing themes. The Sraffa documents have been available elsewhere, but the chronological order of the documents in this volume means that we can now see them in the wider context of Wittgenstein’s ongoing activity.Wittgenstein and Sraffa were both equals and opposites—equal in genius, in honesty, in forthrightness, in stubbornness, and in commitment to dialogue, but opposite in opinions and convictions. Time and again, the letters and notes show evidence of tough, wrenching discussions, at times suspended because of exhaustion and weariness. Wittgenstein lists Sraffa last (chronologically, we presume) of ten people who influenced his thought. The letters and notes in this volume confirm a powerful influence, but offer scant clues as to the direction of the influence in Wittgenstein’s later thought.One of the younger scholars was the physicist W. H. Watson, who became Distinguished Professor at Queen’s University in Kingston, Ontario. His On Understanding Physics is, [End Page 115] McGuinness reports, a reliable guide of Wittgenstein’s thinking on these matters. In their correspondence we find many instances of what they both regarded as nonsense penned by the great scientists of the day (Jeans, Eddington, and Einstein). The nonsense appears to have presented grand pronouncements in everyday language, concerning mundane rather than distinctively philosophical matters. By providing new insight into how Wittgenstein relished nonsensical items, the correspondence with Watson helps us appreciate Wittgenstein’s nose for nonsense as part of his philosophical genius.For Wittgenstein, happiness depended on work. This is evident in his Notebooks 1914–1916 and again in these documents. For example, on June 17, 1941, he writes to Moore, “About six weeks ago I suddenly... began to be able to write again. Quite possibly this will last only for a very short time; but it feels good while it lasts and has made a great deal of difference to me... (shrink)

The problem of the irreversibility’s origin in thermodynamic processes occupies a distinguished place among many and lasting attempts by researchers to derive irreversibility from molecular-mechanical principles. However, this problem is still open and no universally accepted solution may be given during any course. In this paper, I shall try to show that the examining of Maxwell’s demon thought experiment may provide insight into the difficulties that emerge, looking for this origin because: (i) it is connected with the notion (...) of irreversibility, and (ii) one of its functions is that of the “reversibility objection.” In order to illustrate this point, I study Boltzmann’s approach to the problem of a molecular-mechanical interpretation of irreversibility and I show that an auxiliary assumption (the selected direction of time) is responsible for producing irreversibility. But this result is accordant with the predictions of Maxwell’s demon thought experiment: the assumptions of this kind are not dictated by molecular-mechanical principles but are separate input in the model-systems used.

It is a curious feature of Hegelian studies in English that its practitioners seem incapable of tackling their subject without first disclaiming any adherence to the more metaphysical side of Hegel's thought, be it called “speculative metaphysics,” “dialectical logic” or whatever. I say “curious” because I doubt that the same scholars would feel obliged to enter an equivalent disclaimer at the head of a study on, say, Aristotle, Descartes, Spinoza or even Newton—even though all of these classics have a (...) metaphysical side at least as abstruse as any of Hegel's worse romantic excesses. Hegel himself, if he could witness the practice, would be flattered by it. He would not see it as an indication that “the problems of [his] logic remain alien and artificial to us in ways that the problems of Cartesian and Kantian philosophy do not” but, on the contrary, as a hidden acknowledgement that, whether for good or bad, his philosophy is still alive, still so close to our culture that we instinctively feel the need of exorcizing it ritually, like a demon capable of frightening us.
