We investigate the meaning of the wave function by analyzing the mass and charge density distributions of a quantum system. According to protective measurement, a charged quantum system has effective mass and charge density distributing in space, proportional to the square of the absolute value of its wave function. In a realistic interpretation, the wave function of a quantum system can be taken as a description of either a physical field or the ergodic motion of a particle. The essential difference (...) between a field and the ergodic motion of a particle lies in the property of simultaneity; a field exists throughout space simultaneously, whereas the ergodic motion of a particle exists throughout space in a time-divided way. If the wave function is a physical field, then the mass and charge density will be distributed in space simultaneously for a charged quantum system, and thus there will exist gravitational and electrostatic self-interactions of its wave function. This not only violates the superposition principle of quantum mechanics but also contradicts experimental observations. Thus the wave function cannot be a description of a physical field but a description of the ergodic motion of a particle. For the later there is only a localized particle with mass and charge at every instant, and thus there will not exist any self-interaction for the wave function. Which kind of ergodic motion of particles then? It is argued that the classical ergodic models, which assume continuous motion of particles, cannot be consistent with quantum mechanics. Based on the negative result, we suggest that the wave function is a description of the quantum motion of particles, which is random and discontinuous in nature. On this interpretation, the square of the absolute value of the wave function not only gives the probability of the particle being found in certain locations, but also gives the probability of the particle being there. We show that this new interpretation of the wave function provides a natural realistic alternative to the orthodox interpretation, and its implications for other realistic interpretations of quantum mechanics are also briefly discussed.

We present a general theory of scope and binding in which both crossover and superiority violations are ruled out by one key assumption: that natural language expressions are normally evaluated (processed) from left to right. Our theory is an extension of Shan’s (2002) account of multiple-wh questions, combining continuations (Barker, 2002) and dynamic type-shifting. Like other continuation-based analyses, but unlike most other treatments of crossover or superiority, our analysis is directly compositional (in the sense of, e.g., Jacobson, 1999). In particular, (...) it does not postulate a level of Logical Form or any other representation distinct from surface syntax. One advantage of using continuations is that they are the standard tool for modeling order-of-evaluation in programming languages. This provides us with a natural and independently motivated characterization of what it means to evaluate expressions from left to right. We give a combinatory categorial grammar that models the syntax and the semantics of quantifier scope and wh-question formation. It allows quantificational binding but not crossover, in-situ wh but not superiority violations. In addition, the analysis automatically accounts for a variety of sentence types involving binding in the presence of pied piping, including reconstruction cases such as Whose criticism of hisi mother did each personi resent?

This paper presents syntactic and semantic rules for a fragment of English with mixed quotation. The fragment shows that quotation has a recursive and compositional structure. Quoted expressions turn out to denote characters, so the semantics of quotation simulates the pragmatics of speech, including dependence on utterance contexts and reference to mental entities. The analysis also accommodates varieties of unquotation, pure quotation, and causal reference.

We give a new argument supporting a gravitational role in quantum collapse. It is demonstrated that the discreteness of space-time, which results from the proper combination of quantum theory and general relativity, may inevitably result in the dynamical collapse of thewave function. Moreover, the minimum size of discrete space-time yields a plausible collapse criterion consistent with experiments. By assuming that the source to collapse the wave function is the inherent random motion of particles described by the wave function, we further (...) propose a concrete model of wavefunction collapse in the discrete space-time. It is shown that the model is consistent with the existing experiments and macroscopic experiences. (shrink)

Despite Kant’s lasting influence on philosophical accounts of moral motivation, many details of his own position remain elusive. In the Critique of Practical Reason, for example, Kant argues that our recognition of the moral law’s authority must elicit both painful and pleasurable feelings in us. On reflection, however, it is unclear how these effects could motivate us to act from duty. As a result, Kant’s theory of moral sensibility comes under a skeptical threat: the possibility of a morally motivating feeling (...) seems incoherent. My aim in this paper is to reconstruct Kant’s theory in a way that overcomes this threat. By way of conclusion, I show how my reconstruction brings a new perspective to a long-standing dispute over intellectualist and affectivist views of moral motivation. (shrink)

It is shown that Uffink's attempt to protect the interpretation of the wave function against protective measurements fails due to several errors in his arguments.

We show that the physical meaning of the wave function can be derived based on the established parts of quantum mechanics. It turns out that the wave function represents the state of random discontinuous motion of particles, and its modulus square determines the probability density of the particles appearing in certain positions in space.

Abstract: In recent work Stephen Darwall has attacked what he calls J. G. Fichte's ‘voluntarist’ thesis, the idea—on Darwall's reading—that I am bound by obligations of respect to another person by virtue of my choice to interact with him. Darwall argues that voluntary choice is incompatible with the normative force behind the concept of a person, which demands my respect non-voluntarily. He in turn defends a ‘presuppositional’ thesis which claims that I am bound by obligations of respect simply by recognizing (...) the other as a person. In this paper I argue Darwall has misidentified the voluntary element in Fichte's account (sections 4–5). This requires me first to explain what Fichte's voluntarism really consists in (sections 1–3), and I suggest an apparent ambiguity in Fichte's position is responsible for Darwall's misreading. Clarifying this ambiguity, however, exposes some limitations to Darwall's thesis, and I end by discussing what those limitations are and what we can learn from them (sections 6–8). (shrink)

Science has made a mighty advance since it originated in ancient Greece more than 2500 years ago. Yet we still live in Plato's cave today; we think everything around us moves continuously, but continuous motion is merely a shadow of real motion. This book will lead you to walk out the cave along a logical and comprehensible road. After passing Zeno's arrow, Newton's inertia, Einstein's light, and Schrodinger's cat, you will reach the real world, where every thing in the universe, (...) whether it is an atom or a ball or even a star, ceaselessly jumps in a random and discontinuous way. In a famous metaphor, God does play dice with the universe. Discovering motion is not continuous but discontinuous and random is like finding the Earth is not at rest but moving. The new discovery may finally solve Zeno's paradoxes and the quantum puzzle, and it will lead to a profound shift in our world view. (shrink)

Kant’s doctrine of the Fact of Reason is one of the most perplexing aspects of his moral philosophy. The aim of this paper is to defend Kant’s doctrine from the common charge of dogmatism. My defense turns on a previously unexplored analogy to the notion of ‘matters of fact’ popularized by members of the Royal Society in the seventeenth century. In their work, ‘facts’ were beyond doubt, often referring to experimental effects one could witness first hand. While Kant uses the (...) German equivalent in different contexts, I argue that the scientific analogy opens up a new framework for interpreting his strategy of justification in the Critique of Practical Reason. In the final section, I address a few possible objections to my reading, one of which I anticipate coming from Dieter Henrich and Ian Proops, who have argued that Kant’s Fact of Reason is best understood under a legal analogy.

This essay argues that the practice ofmedicine is not a phronetic activity in theoriginal Aristotelian sense of that term. Jonsen andToulmin are two philosophers who have conflated thetechne of medicine with phronesis. Thisconflation ignores Aristotle's crucial distinctionbetween techne and phronesis and his useof the medical analogy. It is argued that medicalreasoning is similar to phronesis but does notexemplify it. Phronesis will not save thelife of medical ethics. The concept could be utilized as amoral prosthetic.

This article analyzes the implications of protective measurement for the meaning of the wave function. According to protective measurement, a charged quantum system has mass and charge density proportional to the modulus square of its wave function. It is shown that the mass and charge density is not real but effective, formed by the ergodic motion of a localized particle with the total mass and charge of the system. Moreover, it is argued that the ergodic motion is not continuous but (...) discontinuous and random. This result suggests a new interpretation of the wave function, according to which the wave function is a description of random discontinuous motion of particles, and the modulus square of the wave function gives the probability density of the particles being in certain locations. It is shown that the suggested interpretation of the wave function disfavors the de Broglie-Bohm theory and the many-worlds interpretation but favors the dynamical collapse theories, and the random discontinuous motion of particles may provide an appropriate random source to collapse the wave function.

Socially responsible investment (SRI) has increasingly assumed a major role in global equity markets. In this article we argue that the continued growth in investors seeking to align their ethical concerns with their investment strategies may influence the way in which the employment relationship is managed in publicly-listed corporations. After tracing the historical development of SRI, its implications for the conduct of human resource management (HRM) are examined. We conclude by analysing a number of the key problems associated with investor (...) confidence in SRI funds and present a range of suggested techniques for improving screening methodologies.

Moral responsibility is one of the core concepts in engineering ethics and consequently in most engineering ethics education. Yet, despite a growing awareness that engineers should be trained to become more sensitive to cultural differences, most engineering ethics education is still based on Western approaches. In this article, we discuss the notion of responsibility in Confucianism and explore what a Confucian perspective could add to the existing engineering ethics literature. To do so, we analyse the Citicorp case, a widely discussed (...) case in the existing engineering ethics literature, from a Confucian perspective. Our comparison suggests the following. When compared to virtue ethics based on Aristotle, Confucianism focuses primarily on ethical virtues; there is no explicit reference to intellectual virtues. An important difference between Confucianism and most western approaches is that Confucianism does not define clear boundaries of where a person’s responsibility end. It also suggests that the gap between Western and at least one Eastern approach, namely Confucianism, can be bridged. Although there are differences, the Confucian view and a virtue-based Western view on moral responsibility have much in common, which allows for a promising base for culturally inclusive ethics education for engineers.

It is commonly held that Kant ventured to derive morality from freedom in Groundwork III. It is also believed that he reversed this strategy in the second Critique, attempting to derive freedom from morality instead. In this paper, I set out to challenge these familiar assumptions: Kant’s argument in Groundwork III rests on a moral conception of the intelligible world, one that plays a similar role as the ‘fact of reason’ in the second Critique. Accordingly, I argue, there is no (...) reversal in the proof-structure of Kant’s two works. (shrink)

Although many studies have previously examined medicalisation, we add a new dimension to the concept as we explore how contemporary oncological medicine shapes the dying self as predominantly medical. Through an analysis of multiple case studies collected within a comprehensive cancer centre in Ontario, Canada, we examine how people with late‐stage cancer and their healthcare providers enacted the process of medicalisation through engaging in the search for oncological treatments, such as experimental drug trials, despite the incurability of their disease. The (...) seven cases included 20 interviews with patients, family, physicians and nurses, the analysis of 30 documents and 5 hr of field observation. A poststructural perspective informed our study. We propose that searching for life extension enacts medicalisation by shaping the dying person afflicted with terminal cancer into new medical subjectivities that are knowledgeable, active, entrepreneurial and curative. Participants initially took up medical thinking from the formal oncology system, but then began to apply and internalise medical rationalities to alter their personhood, thereby generating new curative possibilities for themselves. For people seeking life extension, the embodied and day‐to‐day experiences of suffering and being close to death became expressed and moderated in fundamentally medicalised terms. (shrink)

We analyze the possible implications of spacetime discreteness for the special and general relativity and quantum theory. It is argued that the existence of a minimum size of spacetime may explain the invariance of the speed of light in special relativity and Einstein’s equivalence principle in general relativity. Moreover, the discreteness of spacetime may also result in the collapse of the wave function in quantum mechanics, which may provide a possible solution to the quantum measurement problem. These interesting results might (...) have some important implications for a complete theory of quantum gravity. (shrink)

Ludwig Wittgenstein's Tractatus Logico-Philosophicus (1922) remains one of the most enigmatic works of twentieth century thought. In this bold and original new study, Ben Ware argues that Wittgenstein's early masterpiece is neither an analytic treatise on language and logic, nor a quasi-mystical work seeking to communicate 'ineffable' truths. Instead, we come to understand the Tractatus by grasping it in a twofold sense: first, as a dialectical work which invites the reader to overcome certain 'illusions of thought'; and second as a (...) modernist work whose anti-philosophical ambition is intimately tied to its radical aesthetic character. By placing the Tractatus in the force field of modernism, Dialectic of the Ladder clears the ground for a new and challenging exploration of the work's ethical dimension. It also casts new light upon the cultural, aesthetic and political significances of Wittgenstein's writing, revealing hitherto unacknowledged affinities with a host of philosophical and literary authors, including Hegel, Kierkegaard, Marx, Nietzsche, Adorno, Benjamin, and Kafka.

The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force. In this paper, we will argue that the idea of gravity as an entropic force is debatable. It is shown that there is no convincing analogy between gravity and entropic force in Verlinde’s example. Neither holographic screen nor test particle satisfies all requirements for the existence of entropic force in a thermodynamics (...) system. As a result, there is no entropic force in the gravity system. Furthermore, we show that the entropy increase of the screen is not caused by its statistical tendency to increase entropy as required by the existence of entropic force, but in fact caused by gravity. Therefore, Verlinde’s argument for the entropic origin of gravity is problematic. In addition, we argue that the existence of a minimum size of spacetime, together with the Heisenberg uncertainty principle in quantum theory, may imply the fundamental existence of gravity as a geometric property of spacetime. This provides a further support for the conclusion that gravity is not an entropic force. (shrink)

The relation between quantum collapse, consciousness and superluminal communication is analyzed. As we know, quantum collapse, if exists, can result in the appearance of quantum nonlocality, and requires the existence of a pre- ferred Lorentz frame. This may permit the realization of quantum superluminal communication (QSC), which will no longer result in the usual causal loop in case of the existence of a preferred Lorentz frame. The possibility of the existence of QSC is further analyzed under the assumption that quantum (...) collapse is a real process. We demonstrate that the combination of quantum collapse and the consciousness of the observer will permit the observer to distinguish nonorthogonal states in principle. This provides a possible way to realize QSC. Some implications of the existence of QSC are briefy discussed. (shrink)

Medical futility is often defined as providing inappropriate treatments that will not improve disease prognosis, alleviate physiological symptoms, or prolong survival. This understanding of medical futility is problematic because it rests on the final outcomes of procedures that are narrow and medically defined. In this article, Walker's `expressivecollaborative' model of morality is used to examine how certain critical care interventions that are considered futile actually have broader social functions surrounding death and dying. By examining cardiopulmonary resuscitation and life-sustaining intensive care (...) measures as moral practices, we show how so-called futile interventions offer ritualistic benefit to patients, families, and health care providers, helping to facilitate the process of dying. This work offers a new perspective on the ethical debate concerning medical futility and provides a means to explore how the social value of treatments may be as important in determining futility as medical scientific criteria.

We investigate the implications of protective measurement for de Broglie-Bohm theory, mainly focusing on the interpretation of the wave function. It has been argued that the de Broglie-Bohm theory gives the same predictions as quantum mechanics by means of quantum equilibrium hypothesis. However, this equivalence is based on the premise that the wave function, regarded as a Ψ-field, has no mass and charge density distributions. But this premise turns out to be wrong according to protective measurement; a charged quantum system (...) has effective mass and charge density distributing in space, proportional to the square of the absolute value of its wave function. Then in the de Broglie-Bohm theory both Ψ-field and Bohmian particle will have charge density distribution for a charged quantum system. This will result in the existence of an electrostatic self-interaction of the field and an electromagnetic interaction between the field and Bohmian particle, which not only violates the superposition principle of quantum mechanics but also contradicts experimental observations. Therefore, the de Broglie-Bohm theory as a realistic interpretation of quantum mechanics is problematic according to protective measurement. Lastly, we briefly discuss the possibility that the wave function is not a physical field but a description of some sort of ergodic motion (e.g. random discontinuous motion) of particles. (shrink)

The study aims to help characterize the sort of structures about which people can acquire unconscious knowledge. It is already well established that people can implicitly learn n-grams and also repetition patterns. We explore the acquisition of unconscious structural knowledge of symmetry. Chinese Tang poetry uses a specific sort of mirror symmetry, an inversion rule with respect to the tones of characters in successive lines of verse. We show, using artificial poetry to control both n-gram structure and repetition patterns, that (...) people can implicitly learn to discriminate inversions from non-inversions, presenting a challenge to existing models of implicit learning.

The concept of respect for persons is often rejected as a basis for understanding forgiveness. As many have argued, to hold your offender responsible for her actions is to respect her as a person; but this kind of respect is more likely to sustain, rather than dissolve, your resentment toward her (Garrard & McNaughton 2003; 2011; Allais 2008). I seek to defend an alternative view in this paper. To forgive, on my account, involves ceasing to identify your offender with her (...) wrongdoing, and this requires a corresponding affective change on your behalf. While there are different ways this may happen, I argue that respect for your offender as a person can play a significant role in the process. (shrink)

Counterproductive work behavior is one of the most common behavioral decisions of employees in the workplace that negatively impacts the sustainable development of enterprises. Previous studies have shown that individuals make CWB decisions for different reasons. Some individuals engage in CWB due to cognitive factors, whereas others engage in CWB in response to leadership behaviors. The conservation of resources theory holds that individuals have the tendency to preserve, protect and acquire resources. When experiencing the loss of resources, individuals will show (...) irrational and aggressive behaviors in order to regain resources. When obtaining resources, individuals’ tension and pressure will be relieved. To maintain or continue obtaining resources, individuals will show more positive work attitudes and behaviors. Therefore, using the COR theory as the main theoretical framework, this study explores a serial mediation model between family supportive leadership and CWB through work-family conflict and moral disengagement, moderated by personal life attribution. A three-wave survey of 251 medical workers from three hospitals found that family supportive leadership can reduce employees’ perceived work-family conflict, which leads to less moral disengagement, resulting in lower CWB. Personal life attribution strengthens the negative indirect effect of family supportive leadership on CWB by reinforcing the negative association between family supportive leadership and work-family conflict. This study uses the COR theory to explore the mechanism and boundary conditions of family supportive leadership and CWB from the perspective of negative work-family relationship, which enrichis the research content of existing theories. Moreover, this study has important guiding significance for managers to take effective measures to reduce CWB. (shrink)

The meaning of the wave function and its evolution are investigated. First, we argue that the wave function in quantum mechanics is a description of random discontinuous motion of particles, and the modulus square of the wave function gives the probability density of the particles being in certain locations in space. Next, we show that the linear non-relativistic evolution of the wave function of an isolated system obeys the free Schrödinger equation due to the requirements of spacetime translation invariance and (...) relativistic invariance. Thirdly, we argue that the random discontinuous motion of particles may lead to a stochastic, nonlinear collapse evolution of the wave function. A discrete model of energy-conserved wavefunction collapse is proposed and shown consistent with existing experiments and our macroscopic experience. Besides, we also give a critical analysis of the de Broglie-Bohm theory, the many-worlds interpretation and other dynamical collapse theories, and briefly discuss the issues of unifying quantum mechanics and relativity.

According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunction collapse, e.g. a quantum superposition of two different space–time geometries will collapse to one of them due to the ill-definedness of the time-translation operator for the superposition. In this paper, we argue that Penrose's conjecture on gravity's role in wavefunction collapse is debatable. First of all, it is still a controversial issue what the (...) exact nature of the conflict is and how to resolve it. Secondly, Penrose's argument by analogy is too weak to establish a necessary connection between wavefunction collapse and the conflict as understood by him. Thirdly, the conflict does not necessarily lead to wavefunction collapse. The reason is that the conflict or the problem of ill-definedness for a superposition of different space–time geometries also needs to be solved before the collapse of the superposition finishes, and once the conflict has been resolved, the wavefunction collapse will lose its physical basis relating to the conflict. In addition, we argue that Penrose's suggestions for the collapse time formula and the preferred basis are also problematic. (shrink)

It has been widely thought that consciousness has no causal efficacy in the physical world. However, this may be not the case. In this paper, we show that a conscious being can distinguish definite perceptions and their quantum superpositions, while a physical measuring system without consciousness cannot distinguish such nonorthogonal quantum states. The possible existence of this distinct quantum physical effect of consciousness may have interesting implications for the science of consciousness. In particular, it suggests that consciousness is not emergent (...) but a fundamental feature of the universe. This may provide a possible quantum basis for panpsychism. (shrink)

It is shown that the superposed wave function of a measuring device, in each branch of which there is a definite measurement result, does not correspond to many mutually unobservable but equally real worlds, as the superposed wave function can be observed in our world by protective measurement.

In this article I offer a critical commentary on Jeanine Grenberg’s claim that, by the time of the second Critique, Kant was committed to the view that we only access the moral law’s validity through the feeling of respect. The issue turns on how we understand Kant’s assertion that our consciousness of the moral law is a ‘fact of reason’. Grenberg argues that all facts must be forced, and anything forced must be felt. I defend an alternative interpretation, according to (...) which the fact of reason refers to the actuality of our moral consciousness. (shrink)

The Healing Virtues explores the intersection of psychotherapy and virtue ethics - with an emphasis on the patient's role within a healing process. It considers how the common ground between the therapeutic process and the cultivation of virtues can inform the efforts of both therapist and patient. Within this book, the Duff R. Waring argues that there is a case for patient virtues that are crucially relevant to working through the problems in living that arise in psychotherapy, e.g., honesty, courage, (...) humility, perseverance. The central idea is that treatment may need to build virtues while it ameliorates problems. Hence, the patient's work in psychotherapy can both challenge character strengths and result in their further development. (shrink)

There is no question that Fichte's theory of conscience is central to his system of ethics. Yet his descriptions of its role in practical deliberation appear inconsistent, if not contradictory. Many scholars have claimed that for Fichte conscience plays a material role by providing the content of our moral obligations—the Material Function View. Some have denied this, however, claiming that conscience only plays a formal role by testing our moral convictions in any given case—the Formal Function View. My aim in (...) this paper is to offer a new contribution to this debate. I begin by supplying further evidence in support of the view that conscience only plays a formal function in Fichte's ethics. Then I call attention to a deeper problem this view faces, namely, that it invites an infinite regress by making one's conviction a matter of higher-order reflection. The key to overcoming this threat, I argue, lies in Fichte's doctrine of feeling, whereby the criterion of one's conviction lies, not in a cognitive state, but in an affective state. In closing, I discuss the relevance of Fichte's theory for current debates over the nature of moral error and moral deference. (shrink)

One of the central questions of Jacques Derrida's later writings concerns the sources of religion. At times he gives explicit priority to the universal dimension of religion. In other places, however, he considers the primacy of faith in its concrete, historical context. This paper will clarify Derrida's relationship to universality and historicity by first comparing his notion of "messianicity without messianism" to that of Walter Benjamin's "weak Messianism." After drawing out these differences, I will focus on Derrida's later writings. I (...) will show that much of the ambiguity of Derrida's thinking on religion can be resolved by turning to his work on khōra, the Greek word for "space" or "matter." The rhetoric of khōra can allow us to think through a twofold logic, one that includes the universal/historical distinction and exceeds its alternatives. (shrink)

Facial expressions of emotion play an important role in human social interactions. However, posed expressions of emotion are not always the same as genuine feelings. Recent research has found that facial expressions are increasingly used as a tool for understanding social interactions instead of personal emotions. Therefore, the credibility assessment of facial expressions, namely, the discrimination of genuine (spontaneous) expressions from posed (deliberate/volitional/deceptive) ones, is a crucial yet challenging task in facial expression understanding. With recent advances in computer vision and (...) machine learning techniques, rapid progress has been made in recent years for automatic detection of genuine and posed facial expressions. This paper presents a general review of the relevant research, including several spontaneous vs. posed (SVP) facial expression databases and various computer vision based detection methods. In addition, a variety of factors that will influence the performance of SVP detection methods are discussed along with open issues and technical challenges in this nascent field. (shrink)

This book offers an integrated historical and philosophical examination of the origin of genetics. The author contends that an integrated HPS analysis helps us to have a better understanding of the history of genetics, and sheds light on some general issues in the philosophy of science. This book consists of three parts. It begins with historical problems, revisiting the significance of the work of Mendel, de Vries, and Weldon. Then it turns to integrated HPS problems, developing an exemplar-based analysis of (...) the development and the progress in early genetics. Finally, it discusses philosophical problems: conceptual change, evidence, and theory choice. Part I lays out a new historiography, serving as a basis for the discussions in part II and part III. Part II introduces a new integrated HPS method to analyse and interpret the historiography in Part I and to re-examine the philosophical issues in Part III. Part III develops new philosophical accounts which will in turn make a better sense of the history of scientific practice more generally. This book provides a practical defence of integrated HPS: the best way to defend integrated HPS is to do it. (shrink)

Protective measurement is a new measuring method introduced by Aharonov, Anandan and Vaidman. By a protective measurement, one can measure the expectation value of an observable on a single quantum system, even if the system is initially not in an eigenstate of the measured observable. This remarkable feature of protective measurements was challenged by Uffink. He argued that only observables that commute with the system's Hamiltonian can be protectively measured, and a protective measurement of an observable that does not commute (...) with the system's Hamiltonian does not actually measure the observable, but measure another related observable that commutes with the system's Hamiltonian. In this paper, we show that there are several errors in Uffink's arguments, and his alternative interpretation of protective measurements is untenable. (shrink)
