A novel manifestation of nonlocality of quantum mechanics is presented. It is shown that it is possible to ascertain the existence of an object in a given region of space without interacting with it. The method might have practical applications for delicate quantum experiments.

So quantum mechanics has been an amazing success story. I stress this point at the outset, for two reasons. First, it is, unfortunately, all too easy to get used to success. Nowadays, both physicists, for whom the various quantum theories have ...

By presenting a wide spectrum of non-reductive theories, the volume endeavors to overcome the dichotomy between dualism and monism that keeps plaguing the debate in favor of new and more differentiated positions.

This paper’s outline is as follows. In sections 1-3 I give an exposi¬tion of the Mind-Body Problem, with emphasis on what I believe to be the heart of the problem, namely, the Percepts-Qualia Nonidentity and its incompatibility with the Physical Closure Paradigm. In 4 I present the “Qualia Inaction Postulate” underlying all non-interactionist theo¬ries that seek to resolve the above problem. Against this convenient postulate I propose in section 5 the “Bafflement Ar¬gument,” which is this paper's main thesis. Sections 6-11 (...) critically dis¬cuss attempts to dismiss the Bafflement Argument by the “Baf¬flement=Mis¬perception Equation.” Section 12 offers a refutation of all such attempts in the form of a concise “Asymmetry Proof.” Section 13 points out the bearing of the Bafflement Argument on the evolutionary role of consciousness while section 14 acknowledges the price that has to be paid for it in terms of basic physical principles. Section 15 summarizes the paper, pointing out the inescapability of interactionist dualism. (shrink)

Moody's thought-experiment invoking zombies to demonstrate the uniqueness of consciousness is commended. His conclusions accord well with previous ones arrived at by Penrose, Chalmers and myself. All these works lead to a disturbing conclusion: onsciousness, as something distinct from the brain processes, interferes with physical reality. Ergo, it is no longer possible to adhere to any of the modern theories of mind that preserve the completeness of physics. This conclusion is, in principle, testable.

Lack of distinction between the formalism of quantum mechanics and its various interpretations leads to some popular misrepresentations. As long as none of the interpretations can present an unambiguous empirical validation, their status remains purely philosophical. These arguments are shown to apply to Snyder's claims. Next it is shown that Snyder's critcism does not address the main points in the argument concerning the physical impact of consciousness. The reply concludes with some reflections on methodology in the search for a physical (...) theory of consciousness. (shrink)

A Gedanken experiment is presented where an excited and a ground-state atom are positioned such that, within the former’s half-life time, they exchange a photon with 50% probability. A measurement of their energy state will therefore indicate in 50% of the cases that no photon was exchanged. Yet other measurements would reveal that, by the mere possibility of exchange, the two atoms have become entangled. Consequently, the “no exchange” result, apparently precluding entanglement, is non-locally established between the atoms by this (...) very entanglement. This quantum-mechanical version of the ancient Liar Paradox can be realized with already existing transmission schemes, with the addition of Bell’s theorem applied to the no-exchange cases. Under appropriate probabilities, the initially-excited atom, still excited, can be entangled with additional atoms time and again, or alternatively, exert multipartite nonlocal correlations in an interaction free manner. When densely repeated several times, this result also gives rise to the Quantum Zeno effect, again exerted between distant atoms without photon exchange. We discuss these experiments as variants of interaction-free-measurement, now generalized for both spatial and temporal uncertainties. We next employ weak measurements for elucidating the paradox. Interpretational issues are discussed in the conclusion, and a resolution is offered within the Two-State Vector Formalism and its new Heisenberg framework. (shrink)

The first reaction with which one is likely to greet such a book is "at last!" Psychology, is an inevitable side-product of its modern success, has become a major contributor to the growing pseudoscience literature. A careful examination of this nonesense industry, and of the motives behind it, is an undertaking worthy of a university psychologist. Terence Hines, known to readers of this journal from a lively debate following his harsh criticism of a sloppy psychology book , has now undertaken (...) this task. (shrink)

Special relativity is based on the apparent contradiction between two postulates, namely, Galilean vs. c-invariance. We show that anomalies ensue by holding the former postulate alone. In order for Galilean invariance to be consistent, it must hold not only for bodies’ motions, but also for the signals and forces they exchange. If the latter ones do not obey the Galilean version of the Velocities Addition Law, invariance is violated. If, however, they do, causal anomalies, information loss and conservation laws’ violations (...) are bound to occur. These anomalies are largely remedied by introducing waves and fields that disobey Galilean invariance. Therefore, from these inconsistencies within classical mechanics, electromagnetism could be predicted before experiment proved its existence. Special relativity, it might be argued, would then follow naturally, either as a resolution of the resulting conflict or as an extrapolation of the path between the theories. We conclude with a review of earlier attempts to base SR on a single postulate, and point out the originality of the present work. (shrink)

In the process of implementing an ethical code of conduct, a business organization uses formal methods. Of these, training, courses and means of enforcement are common and are also suitable for self-regulation. The USA is encouraging business corporations to self regulate with the Federal Sentencing Guidelines (FSG). The Guidelines prescribe similar formal methods and specify that, unless such methods are used, the process of implementation will be considered ineffective, and the business will therefore not be considered to have complied with (...) the guidelines. Business organizations invest enormous funds on formal methods. However, recent events indicate that these are not, by themselves, yielding the desired results. Our study, based on a sample of 812 employees and conducted in an Israeli subsidiary of a leading multinational High-Tech corporation headquartered in the US, indicates that, of the methods used in the process of implementation, one of the informal methods (namely, the social norms of the organization) is perceived by employees to have the most influence on their conduct. This result, when examined against employee tenure, remains relatively stable over the years, and stands in contradistinction to the formalistic approach embedded in the FSG. We indirectly measure the effectiveness of the percieved most influential implementation process methods by analyzing their impact on employee attitudes (namely, personal ethical commitment and employees'' commitment to organizational values). Our results indicate that the informal methods (manager sets an example or social norms of the organization) are likely to yield greater commitment with respect to both employee attitudes than the formal method (training and courses on the subject of ethics). The personal control method (my own personal values) differs significantly from all the other methods in that it yields the highest degree of personal ethical commitment and the lowest degree of employees'' commitment to organizational values.

Socially Responsible Investment (SRI) indices play a major role in the stock markets. A connection between doing good and doing well in business is implied. Leading indices, such as the Domini Social Index and others, exemplify the movement toward investing in socially responsible corporations. However, the question remains: Does the ratings-based methodology for assessing corporate social responsibility (CSR) provide an incentive to firms excluded from SRI indices to invest in CSR? Not in its current format. The ratings-based methodology employed by (...) SRI indices in their selection processes excludes many corporations by creating limited-membership lists. This received ratings-based structure is yet to offer an incentive for most of the excluded corporations to invest in improving their levels of CSR. We, therefore, ask under what circumstances a ratings-based method for assessing CSR could provide an incentive to firms excluded from SRI indices to invest in CSR. In this article, we attempt to offer a theoretical reply to this question. We show that when all firms are publicly ranked according to SRI index parameters, such indices can indeed create a market incentive for increased investment by firms in improving their performance in the area of social responsibility. We further show that this incentive tapers off as the amount of investment required exceeds a certain point or if the amount of payback on that investment fails to reach a certain threshold.

This paper offers a novel interpretation of the political implications of Hobbes’s theory of imagination and his solution to the threat posed by the imagination to political stability. While recent work has correctly identified the problem the imagination poses for Hobbes, it has underestimated the severity of the problem and, accordingly, has underestimated the length to which the Hobbesian sovereign will have to go in order to solve it. By reconstructing Hobbes’s account of sleep and the operation of the imagination (...) during sleep, this paper argues that the Hobbesian sovereign who seeks to solve the problem of the imagination must maintain his subjects in a ‘state of sleep,’ by preventing any kind of new inputs from disturbing their imagination. This solution suggests that the citizens of the Leviathan state are not sleeping sovereigns, but rather sleeping subjects. (shrink)

In social and political theory, the imagination is often used in accounting both for creativity, innovation, and change and for sociopolitical stagnation and the inability to promote innovation and change. To what extent, however, can we attribute such seemingly contradictory outcomes to the same mental faculty? To address this question, this paper develops a comprehensive account of the political imagination, one that explains the various roles played by imagination in politics and thus accounts for the promises and limits of the (...) political imagination. This conceptualization of the political imagination allows us to account for the simultaneous presence of its seemingly contradictory roles—such as promoting stability and order on the one hand while generating creativity and critical innovation on the other.

Backdating of stock options is an example of an agency problem. It has emerged despite all the measures (i.e., new regulations and additional corporate governance mechanisms) aimed at addressing such problems? Beyond such negative controlling measures, a more positive empowering approach based on ethics may also be necessary. What ethical measures need to be taken to address the agency problem? What values and norms should guide the board of directors in protecting the shareholders' interests? To examine these issues, we first (...) discuss the role values and norms can play with respect to underlying corporate governance and the proper role of directors, such as transparency, accountability, integrity (which is reflected in proper mechanisms of checks and balances), and public responsibility. Second, we discuss various stakeholder approaches (e.g., government, directors, managers, and shareholders) by which conflicts of interest (i.e., the agency problem) can be addressed. Third, we assess the practice of backdating stock options, as an illustration of the agency problem, in terms of whether the practice is legally acceptable or ethically justifiable. Fourth, we proceed to an analysis of good corporate governance practice involving backdating options based on a series of ethical standards including: (1) trustworthiness; (2) utilitarianism; (3) justice; and (4) Kantianism. We conclude that while executive compensation schemes (e. g., stock options) were originally intended to help remedy the agency problem by tying together the interests of the executives and shareholders, these schemes may have actually become "part of the problem," and that the solution ultimately depends upon whether directors and executives accept that all of their actions must be based on a set of core ethical values.

In the late 19th century great changes in theories of light and electricity were in direct conflict with certitude, the view that scientific knowledge is infallible. What is, then, the epistemic status of scientific theory? To resolve this issue Duhem and Poincaré proposed images of fallible knowledge, Instrumentalism and Conventionalism, respectively. Only in 1919–1922, after Einstein's relativity was published, he offered arguments to support Fallibilism, the view that certainty cannot be achieved in science. Though Einstein did not consider Duhem's Instrumentalism, (...) he argued against Poincaré's Conventionalism. Hitherto, Einstein's Fallibilism, as presented at first in a rarely known essay of 1919, was left in the dark. Recently, Howard obscured its meaning. Einstein's essay was never translated into English. In my paper I provide its translation and attempt to shed light on Einstein's view and its context; I also direct attention to Einstein's images of philosophical opportunism in scientific practice.

Despite intensive research on late Roman and Byzantine diplomatic and military history since the last decades of the 19th century, scholars had to wait until the year 2001 for the first monograph which deals exclusively with the foederati.

The book includes an introduction, (...) nine chapters, a conclusion, a bibliography, an index locorum (unfortunately not exhaustive) and a general index. (shrink)

This article offers a new interpretation of the second ‘theological’ pattern in Plato’s Republic. Situating Plato within his religious context, it argues that this pattern calls into question the traditional ancient model of divine epiphany. Divine epiphany was a central element in Greek religion. Yet, in the absence of a centralized religious organization, this model threatened the philosophers’ authoritative position. Plato’s second pattern seeks not only to undermine this potential threat but also to pave the way towards a new, philosophicalmodel (...) of divine epiphany, thus further establishing the philosophers’ authority and legitimacy within and outside his ideal city.

This article provides a new account of the role of phantasia, imagination, in Aristotle's political thought. Phantasia plays a key role in Aristotle's psychology and is crucial for explaining any kind of movement and action. I argue that this insight holds for collective actions as well. By offering a reconsideration of the famous “Wisdom of the Multitude” passage, this article shows that the capacity of a multitude to act together is tied to its ability to share a collective phantasma: a (...) mental representation of the practical end or goal of their collective effort as good and thus worthy of pursuit. However, I argue that given the subjective nature of phantasia, acting together can be hard. I conclude that since one's phantasia is shaped by one's moral character, a community can achieve a shared phantasma—and thus secure collective action—by means of persuasion, habituation, and education.

This paper investigates the development of Hobbes’s theory of imagination and its unique intervention in the scientific debates of the seventeenth century. I argue that this intervention is designed to solve a tension between Hobbes’s scientific and political commitments. His scientific commitments led him to take the imagination seriously. While unorthodox in many ways, Hobbes was working within the predominant scientific framework of his time, which can be traced back to Aristotle and Galen. The same framework, however, was used for (...) naturalistic explanations for prophecy. This posed a problem for Hobbes, who was equally committed to the advances of science and to guarding against the political threat posed by prophets. I argue that Hobbes’s theory of imagination solves this tension by constructing a scientific account of imagination that is loyal to the leading scientific ideas while ruling out any potential use of imagination in the natural explanation of prophecy.

The ontological argument--first proposed by St. Anselm and subsequently deveIoped by Descartes, Leibniz, Kant, Hegel and Marx--furnishes a key to understanding the relationship between thought and reality. In this article we shall focus on Hegel’s attitude towards the ontological argument as set out in his Science of Logic, where it appears as a paradigm of the relationship between thought and reality. It should be remarked, moreover, that our choice of the subject was not random and that it was seIected for (...) the reason that belief in God is a preeminent social reality, inasmuch as faith in God creates His existence. Therefore, an investigation of the concept of God is an inquiry into the most profound recesses of human consciousness.The great opponents of the ontological argument, from Hume down to our day--and even Kant--have based their arguments upon the fundamental empiricist assertion that existential judgments are not analytical. In this paper we attempt to defend the ontological argument against its opponents. (shrink)

It is commonly accepted that the spelling of the pre-exilic books of the Bible was generally defective like that of contemporary epigraphy, and that the matres lectionis were inserted into the original texts by scribes during the first half of the Second Temple period. This article argues that the orthography of the ancient books of the Bible was from its beginning similar to that of the MT. The difference between the current biblical spelling and the defective spelling of the inscriptions (...) should instead be understood as a matter of different registers. (shrink)

Baars’ Global Workspace theory suggests that consciousness functions as a gateway, facilitating focused access to any part of the brain. While this hypothesis does not address the ‘hard problems’, namely, the very nature of consciousness, it constrains any theory that attempts to do so and provides important insights into the relation between consciousness and cognition. Many questions have found new answers once they were turned upside down. In medicine, for example, important discoveries have been made when, instead of asking ‘Why (...) did this disease inflict this person now?’ someone rather asked ‘Why doesn't this disease always inflict all people?’ Bernard Baars tries to do something similar with the mind-body problem. Whereas most people often ask, ‘Why are there conscious experiences accompanying some brain processes?’, he asks, ‘Why aren't there conscious experiences accompanying all brain processes?’. (shrink)
