We argue that the Aharonov-Anandan-Vaidman model, by using the notion of so-called “protective measurements,” cannot claim to have dispensed with the ldcollapse of the wave function,” because it does not succeed in avoiding the quantum measurement problem. Its claim to be able to distinguish between two nonorthogonal states is also critically examined.

We review the present status of wave-particle duality of single-photon states in the context of some recent experiments. In particular, Bohr's complementarity principle is critically reexamined. It is explained in detail how this principle is confronted in these experiments and how a contradiction with the notion of “mutual exclusiveness” of classical wave and particle pictures emerges.

A number of papers on wave-particle duality has appeared since the two-prism experiment was performed by Mizobuchi and Ohtake, based on a suggestion by Ghose, Home, and Agarwal. Against this backdrop, the present paper provides further clarification of the key issues involved in the analysis of the two-prism experiment. In the process, we present an overview of wave-particle duality vis-a vis Bohr's complementarity principle.

Examples are worked out using a new equation proposed in the previous paper to show that it has new physical predictions for mesoscopic systems.

In spite of its popularity, it has not been possible to vindicate the conventional wisdom that classical mechanics is a limiting case of quantum mechanics. The purpose of the present paper is to offer an alternative formulation of mechanics which provides a continuous transition between quantum and classical mechanics via environment-induced decoherence.

The nature of reality has been a long-debated issue among scientists and philosophers. In 1930, Rabindranath Tagore and Albert Einstein had a long conversation on the nature of reality. This conversation has been widely quoted and discussed by scientists, philosophers and scholars from the literary world. The important question that Tagore and Einstein discussed was whether the world is a unity dependent on humanity, or the world is a reality independent on the human factor. Einstein took the stand adopted by (...) Western philosophers and mathematicians, namely that reality is something independent of the mind and the human factor. Tagore, on the other hand, adopted the opposite view. Nevertheless, both Einstein and Tagore claimed to be realists despite the fundamental differences between their conceptions of reality. Where does the difference lie? Can it be harmonized at some deeper level? Can Wittgenstein, for example, be a bridge between the two views? This collection of essays explores these two fundamentally different conceptions of the nature of reality from the perspectives of theories of space-time, quantum theory, general philosophy of science, cognitive science and mathematics.

It is shown that below the threshold of pair creation, a consistent quantum mechanical interpretation of relativistic spin-0 and spin-1 particles (both massive and mussless) ispossible based an the Hamiltonian-Schrödinger form of the firstorder Kemmer equation together with a first-class constraint. The crucial element is the identification of a conserved four-vector current associated with the equation of motion, whose time component is proportional to the energy density which is constrainedto be positive definite for allsolutions. Consequently, the antiparticles must be interpreted (...) as positive-energy states traveling backward in time. This also makes it possible to define hermitian position operators with localized eigensolutions (δ-functions) as well as Bohmian trajectories for bosons. The exact theory is obtained by “second quantization” and is mathematically completely equivalent to conventional quantum field theory. The classical field emerges in the high mean number limit of coherent states of the exact theory. The formalism provides a new basis for computing tunneling times for photons and chaotic phenomena in optics. (shrink)

"The nature of reality has been a long-debated issue among scientists and philosophers.

This comprehensive analysis dives deep into the intricate interplay between artificial intelligence (AI) and human agency, examining the remarkable capabilities and inherent limitations of large language models (LLMs) such as GPT-3 and ChatGPT. The paper traces the complex trajectory of AI's evolution, highlighting its operation based on statistical pattern recognition, devoid of self-consciousness or innate comprehension. As AI permeates multiple spheres of human life, it raises substantial ethical, legal, and societal concerns that demand immediate attention and deliberation. The metaphorical illustration (...) of humans as “shepherds” of AI, coupled with a thought-provoking examination of “agency without intelligence,” engenders deep reflections on the future of human-AI interplay and the associated philosophical, ethical, and practical ramifications. The paper further elucidates critical challenges associated with AI, such as ethical dilemmas, “agency without intelligence,” the role of human oversight, and the environmental impact of AI technologies. In the pursuit of solutions, the paper maps prospective directions, emphasizing the need for robust AI policies, improved AI literacy, sustainable AI practices, and a continued dialogue on the multifaceted issues surrounding AI. Through a holistic exploration of AI, this paper underlines the necessity for a multidisciplinary, collaborative approach to chart an ethical, beneficial, and sustainable AI future, enabling society to harness the potential of AI responsibly while mitigating the associated risks.

Linguists intuitions about language change can be captured by adynamical systems model derived from the dynamics of language acquisition.Rather than having to posit a separate model for diachronic change, as hassometimes been done by drawing on assumptions from population biology (cf.Cavalli-Sforza and Feldman, 1973; 1981; Kroch, 1990), this new modeldispenses with these independent assumptions by showing how the behavior ofindividual language learners leads to emergent, global populationcharacteristics of linguistic communities over several generations. As thesimplest case, we formalize the example of (...) two grammars and show that eventhis situation leads directly to a nonlinear (quadratic) dynamical system.We study this one parameter model in a variety of situations for differentkinds of acquisition algorithms and maturational times, showing howdifferent learning theories can have very different evolutionaryconsequences. This allows us to formulate an evolutionary criterion for theadequacy of grammatical and learning theories. An application of thecomputational model to the historical loss of Verb Second from Old French toModern French is described showing how otherwise adequate grammaticaltheories might fail the evolutionary criterion.

Social thinkers frequently remind us that people differ in their views on what constitutes personal well-being, but that even when they don't differ, they disagree over the extent to which one person's well-being can be permitted to be traded off against another's. In this paper I show, by offering an account of the development of development economics, that in professional debates on social policy, economists speak or write as though they agree on values but differ on their reading of facts. (...) A number of ethicists have concluded from this near-exclusive interest in facts that modern economics must be an ethical desert. It is shown here that the reason research economists analyze facts rather than values is that modern economics is built on broad ethical foundations, capable of being reduced as special cases to the various ethical theories that are currently on offer. Ethics has taken a back seat in modern economics not because contemporary economists are wedded to a “value-free” enterprise, but because the ethical foundations of the subject were constructed over five decades ago and are now regarded to be a settled matter.

The forms of liberal government that emerged after World War II are in the midst of a profound crisis. In I Am the People, Partha Chatterjee reconsiders the concept of popular sovereignty in order to explain today’s dramatic outburst of movements claiming to speak for “the people.” To uncover the roots of populism, Chatterjee traces the twentieth-century trajectory of the welfare state and neoliberal reforms. Mobilizing ideals of popular sovereignty and the emotional appeal of nationalism, anticolonial movements ushered in (...) a world of nation-states while liberal democracies in Europe guaranteed social rights to their citizens. But as neoliberal techniques shrank the scope of government, politics gave way to technical administration by experts. Once the state could no longer claim an emotional bond with the people, the ruling bloc lost the consent of the governed. To fill the void, a proliferation of populist leaders have mobilized disaffected groups into a battle that they define as the authentic people against entrenched oligarchy. Once politics enters a spiral of competitive populism, Chatterjee cautions, there is no easy return to pristine liberalism. Only a counter-hegemonic social force that challenges global capital and facilitates the equal participation of all peoples in democratic governance can achieve significant transformation. Drawing on thinkers such as Antonio Gramsci, Michel Foucault, and Ernesto Laclau and with a particular focus on the history of populism in India, I Am the People is a sweeping, theoretically rich account of the origins of today’s tempests.

Peter Thomas’s criticism of arguments advanced recently of an era of “post-hegemony” in Western democracies may be extended by considering the experience of post-colonial Asia and Africa. Reviewing the use of the Gramscian concepts of consent and passive revolution in the study of modern South Asian history, this paper argues that both of Gramsci’s objectives –a general theory of power and the analysis of historically contingent and strategic politics– can be retained to yield valuable analytical insights. The paper concludes that (...) rather than focusing on whether the analysis of hegemony can remain true to Gramsci’s text, one can put the concept to analytical use in explaining political change in different parts of the world today.

In Human Well-Being and the Natural Environment, Partha Dasgupta explores ways to measure the quality of life. In developing quality-of-life indices, he pays particular attention to the natural environment, illustrating how it can be incorporated, more generally, into economic reasoning in a seamless manner. Professor Dasgupta puts the theory that he develops to use in extended commentaries on the economics of population, poverty traps, global warming, structural adjustment programmes, and free trade, particularly in relation to poor countries. The result (...) is a treatise that goes beyond quality-of-life measures and offers a comprehensive account of the newly emergent subject of ecological economics. (shrink)

Recent data breaches underscore the importance of organizational cybersecurity. However, the high costs of such security can force chief financial officers (CFOs) to make difficult financial and ethical trade-offs that have both business and societal implications. We employ a 2 × 2 randomized experiment that varies both an observed scenario CFO’s investment decision (invest/not invest in security) and organizational outcomes (positive/negative) to investigate these trade-offs. Participant managers assess the observed CFO’s investment behavior and indicate their own intentions to invest. Results (...) indicate that when the observed scenario CFO invests in security, managers primarily follow their peers when making investment decisions. However, when the observed CFO does not invest in security, managers make their own decisions by engaging in more in-depth reasoning that includes assessment of the seriousness of consequences, as well as the ethical and societal considerations. Moderated mediation findings further deconstruct and corroborate these relationships. (shrink)

ABSTRACT This article attempts to define karma as both action and the effects of action. In terms of the effects or fruits of action, the effect of action upon the mind is the focus; thus, the idea of “effect” is primarily defined as psychic residue and is compared to Freud's notion of memory traces. In addition, action that produces karma is said to be accompanied by the “pulling” feeling of volition (cetanā). Some comparisons are then made between cetanā and the (...) theories of Karen Horney in Western psychology vis à vis her view of the neurotic's compulsive, driven feelings. The article also has a more ethically oriented side. Often, the karma doctrine is believed to be the only causal factor responsible for one's present condition, and thus, a person's unfortunate circumstances: sometimes this notion leads to blaming a person for his or her misfortune. This article seeks to discover whether or not this idea truly has scriptural backing. Lastly, the article explores the issue of whether or not one must always live out the entirety of the effects of one's actions or if it is possible to purify or eliminate actions' effects before they come to fruition. For this question in particular, the article examines both Theravāda and Mahāyāna thinking. (shrink)

The paper traces the continuities between empires and successor nation-states and examines how imperial prerogatives continue to operate in the global system. The author also looks at the failure of postcolonial states to deliver on their promises after achieving national sovereignty. In all this, the focus is on conceptualizing the category of ‘the people’, which is supposedly the source of legitimate power in the contemporary world. In particular the paper zooms in on the historical continuity that characterized traditional empires and (...) is just as present in the context of contemporary world powers – the right to invoke imperial prerogatives to declare colonial exceptions.

Social thinkers frequently remind us that people differ on what constitutes personal well-being, but that even when they don't differ, they disagree over the extent to which one person's well-being can be permitted to be traded off against another's. They tell us that political differences are to be traced to differences in people's conceptions of personal and social well-being. We are given to understand, in other words, that people's ethics differ.

[opening paragraph]: Dr. Ramachandran is a distinguished researcher in the field of cognitive neuroscience whose work is grounded in impressive clinical data. As a scientific materialist, he has provided powerful arguments against the metaphysical notion of the ‘self', suggesting that our consciousness is really a biological function of the brain. He and his collaborator, William Hirstein, have now turned to human artistic activity, putting forward the argument that it is essentially a product of neural mechanism. They employ the experimental ‘peak (...) shift effect’ to sustain this hypothesis. The experiment demonstrates that a rat's cognitive achievements are related to the reward it receives for discriminating different shapes. Applying this principle to human responses to the visual image, they argue that certain simplified and exaggerated images, as for instance, caricature, appeal to our emotions and have the innate ability to give us pleasure. Furthermore, the binding of correlated features creates unitary objects that provide further grounds for aesthetic appeal. This is because, given our limited ability to concentrate, the most appealing art is one that produces heightened activity within a single dimension. (shrink)

Traditional accounts of belief change have been criticized for placing undue emphasis on the new belief provided as input. A recent proposal to address such issues is a framework for non-prioritized belief change based on default theories (Ghose and Goebel, 1998). A novel feature of this approach is the introduction of disbeliefs alongside beliefs which allows for a view of belief contraction as independently useful, instead of just being seen as an intermediate step in the process of belief revision. (...) This approach is, however, restrictive in assuming a linear ordering of reliability on the received inputs. In this paper, we replace the linear ordering with a preference ranking on inputs from which a total preorder on inputs can be induced. This extension brings along with it the problem of dealing with inputs of equal rank. We provide a semantic solution to this problem which contains, as a special case, AGM belief change on closed theories. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 29.4 (1999) 128-134 [Access article in PDF] Anderson's Utopia Partha Chatterjee Imagined Communities was, without doubt, one of the most influential books of the late twentieth century. In the years since it was published, as nationalism unexpectedly came to be regarded as an increasingly unresolvable and often dangerous "problem" in world affairs, Benedict Anderson has continued to analyze and reflect on the subject, adding two brilliant chapters (...) to his highly acclaimed book and writing several new essays and lectures. Some of these have been brought together, along with a series of essays on the history and politics of Southeast Asia, in The Spectre of Comparisons. The publication of this volume provides an opportunity for other scholars in the field to reassess the work of, and pay tribute to, a major intellectual of our time. 1 Theoretically, the most significant addition that Anderson has made to his analysis in Imagined Communities is his attempt to distinguish between nationalism and the politics of ethnicity. He does this by identifying two kinds of seriality that are produced by the modern imaginings of community. One is the unbound seriality of the everyday universals of modern social thought: nations, citizens, revolutionaries, bureaucrats, workers, intellectuals, and so on. The other is the bound seriality of governmentality: the finite totals of enumerable classes of population produced by the modern census and the modern electoral systems. Unbound serialities are typically imagined and narrated by means of the classic instruments of print-capitalism, namely, the newspaper and the novel. They afford the opportunity for individuals to imagine themselves as members of larger than face-to-face solidarities, of choosing to act on behalf of those solidarities, of transcending by an act of political imagination the limits imposed by traditional practices. Unbound serialities are potentially liberating. As Anderson quotes from Pramodeya Ananta Toer's novel Dia Jang Menjerah, which describes such a moment of emancipation experienced by one of its characters:By now, Is knew the society she was entering. She had found a circle of acquaintances far wider than the circle of her brothers, sisters and parents. She now occupied a defined position in that society: as a woman, as a typist in a government office, as a free individual. She had become a new human being, with new understanding, new tales to tell, new perspectives, new attitudes, new interests--newnesses that she managed to pluck and assemble from her acquaintances. [qtd. in Spectre 41] Bound serialities, by contrast, can operate only with integers. This implies that for each category of classification, an individual can count only as one or zero, never as a fraction, which in turn means that all partial or mixed affiliations to a category are ruled out. One can only be black or not black, Muslim or not Muslim, tribal or not tribal, never only partially or contextually so. Bound serialities, Anderson suggests, are constricting and perhaps inherently conflictual. They produce the tools of ethnic politics. [End Page 128]I am not sure that the distinction between bound and unbound seriality, despite its appearance of mathematical precision, is the appropriate way to describe the differences in political modalities that Anderson wants to demarcate. It is not clear why the "unbound" serialities of the nationalist imagination cannot, under specific conditions, produce finite and countable classes. Explaining unbound seriality, Anderson says it is that which "makes the United Nations a normal, wholly unparadoxical institution" [29]. But surely, at any given time, the United Nations can have only a finite number of members. And that is because, with its explicitly laid-down procedures and criteria of membership, the imagining of nationhood has been reduced to the institutional grid of governmentality. Again, if by revolutionaries we mean those who are members of revolutionary political parties, then the number of revolutionaries in a country, or even in the whole world, will also be finite and countable, in the same way that the census claims to provide a figure for, let us say, the number of Hindus in India. It is also not clear in what sense the serialities of governmentality are "bound." The series for Christians or English... (shrink)

As part of an article symposium on their “Narrow Identities”, Partha Dasgupta and Sanjeev Goyal respond to commentaries by Jean-Paul Carvalho, John B. Davis, Peter Finke, and Miriam Teschl.

There is a long-standing myth that the history of modern India was foretold at the beginning of the nineteenth century by British liberals who predicted that the enlightened despotic rule of India's new conquerors would, by its beneficial effects, improve the native character and institutions sufficiently to prepare the people of that country one day to govern themselves. Lord William Bentinck, a disciple of Jeremy Bentham, while presenting as governor-general his case for the opening up of India to European settlers, (...) speculated on the possibility of “a vast change to have occurred in the frame of society . . . which would imply that the time had arrived when it would be wise for England to leave India to govern itself”, but added that such change “can scarcely be looked for in centuries to come”. The doctrinal basis within liberal theory for justifying a democratic country like Britain exercising despotic power in colonies such as Ireland and India was securely laid out by mid-century liberals such as John Stuart Mill. The project of “improvement” was revived at the end of the nineteenth century by Gladstonian liberals who inducted elite Indians into new representative institutions based on a very narrow franchise in preparation for some form of self-government. When power was ultimately transferred to the rulers of a partitioned subcontinent in 1947, the history of liberal progress in India was complete. The storyline was laid out, for instance, in Thompson and Garratt's Rise and Fulfilment of British Rule in India or in Percival Spear's revised edition of the hugely successful textbook by Vincent Smith. Even nationalist Indian scholars adopted at least a part of this story, nowhere more so than in the histories of constitutional law which traced the foundations of the postcolonial Indian republic to the progressive expansion of liberal state institutions under British rule.

In developing the basis on which climate change should be priced, I do five things. First, I review the ethical foundations for valuing future consumption relative to present consumption (i.e. social discount rates). Second, I report that the criterion for both assessing and prescribing economic policies should not be an economy's GDP, but an inclusive measure of an economy's wealth adjusted for the distribution of wealth. Third, I apply the resulting analysis to the problem of pricing carbon concentration in the (...) atmosphere. I give prominence to future uncertainties. Fourth, I show that the existing models of human behaviour on the basis of which these questions have been analysed by economists have serious deficiencies, in as much as the idea of personhood embodied in them has been built on the psychology of confirmed egotists. Fifth, I sketch the motivations of a social being and show how the altered specification of the human person affects the social price of climate change. (shrink)
