The aim of this note is to complete the discussion on the possibility of creation of quantum-like (QL) representation for the question order effect which was presented by Wang and Busemeyer (2013). We analyze the role of a fundamental feature of mental operators (given, e.g., by questions), namely, their complementarity.

We presented a contextual statistical model of the probabilistic description of physical reality. Here contexts (complexes of physical conditions) are considered as basic elements of reality. There is discussed the relation with QM. We propose a realistic analogue of Bohr’s principle of complementarity. In the opposite to the Bohr’s principle, our principle has no direct relation with mutual exclusivity for observables. To distinguish our principle from the Bohr’s principle and to give better characterization, we change the terminology and speak (...) about supplementarity, instead of complementarity. Supplementarity is based on the interference of probabilities. It has quantitative expression trough a coefficient which can be easily calculated from experimental statistical data. We need not appeal to the Hilbert space formalism and noncommutativity of operators representing observables. Moreover, in our model there exists pairs of supplementary observables which cannot be represented in the complex Hilbert space. There are discussed applications of the principle of supplementarity outside quantum physics. (shrink)

I argue that instead of a rather narrow focus on N. Bohr's account of complementarity as a particular and perhaps obscure metaphysical or epistemological concept (or as being motivated by such a concept), we should consider it to result from pursuing a particular method of studying physical phenomena. More precisely, I identify a strong undercurrent of Baconian method of induction in Bohr's work that likely emerged during his experimental training and practice. When its development is analyzed in light of (...) Baconian induction, complementarity emerges as a levelheaded rather than a controversial account, carefully elicited from a comprehensive grasp of the available experimental basis, shunning hasty metaphysically motivated generalizations based on partial experimental evidence. In fact, Bohr's insistence on the “classical” nature of observations in experiments, as well as the counterintuitive synthesis of wave and particle concepts that have puzzled scholars, seem a natural outcome (an updated instance) of the inductive method. Such analysis clarifies the intricacies of early Schrödinger's critique of the account as well as Bohr's response, which have been misinterpreted in the literature. If adequate, the analysis may lend considerable support to the view that Bacon explicated the general terms of an experimentally minded strand of the scientific method, developed and refined by scientists in the following three centuries.

Probabilistic dependence and independence are among the key concepts of Bayesian epistemology. This paper focuses on the study of one specific quantitative notion of probabilistic dependence. More specifically, section 1 introduces Keynes’s coefficient of dependence and shows how it is related to pivotal aspects of scientific reasoning such as confirmation, coherence, the explanatory and unificatory power of theories, and the diversity of evidence. The intimate connection between Keynes’s coefficient of dependence and scientific reasoning raises the question of how (...) Keynes’s coefficient of dependence is related to truth, and how it can be made fruitful for epistemological considerations. This question is answered in section 2 of the paper. Section 3 outlines the consequences the results have for epistemology and the philosophy of science from a Bayesian point of view. (shrink)

Each information system leads to a hierarchy of binary relations on the object set in a natural way; these relational systems can serve as frames for the semantics of modal logics. While relations of indiscernibility and their logics have been frequently studied, the situation in the case of relations which distinguish objects is much less clear. In this paper, we present complete logical systems for relations of complementarity derived from information systems.

A growing number of commentators have, in recent years, noted the important affinities in the views of Immanuel Kant and Niels Bohr. While these commentators are correct, the picture they present of the connections between Bohr and Kant is painted in broad strokes; it is open to the criticism that these affinities are merely superficial. In this essay, I provide a closer, structural, analysis of both Bohr's and Kant's views that makes these connections more explicit. In particular, I demonstrate the (...) similarities between Bohr's argument, on the one hand, that neither the wave nor the particle description of atomic phenomena pick out an object in the ordinary sense of the word, and Kant's requirement, on the other hand, that both ‘mathematical’ (having to do with magnitude) and ‘dynamical’ (having to do with an object's interaction with other objects) principles must be applicable to appearances in order for us to determine them as objects of experience. I argue that Bohr's ‘complementarity interpretation’ of quantum mechanics, which views atomic objects as idealizations, and which licenses the repeal of the principle of causality for the domain of atomic physics, is perfectly compatible with, and indeed follows naturally from a broadly Kantian epistemological framework.

New sciences born or developed in the 20th century (information, materials, life science) are based on forms of complementarity that differ from the past. The paper discusses cognitive, or disciplinary, institutional, and technical complementarity. It argues that new sciences apply a reductionist explanatory strategy to complex multi-layered systems. In doing so the reductionist promise is falsified, generating the need for multi-level kinds of explanation (e.g. in post-genomic molecular biology), new forms of complementarity between scientific and non-scientific organizations, (...) and new forms of experimental and informational facilities. The paper develops the argument in theoretical terms, comparing it with the STS literature, and offers preliminary evidence based on the experience of Networks of Excellence. (shrink)

This paper is the sequel of a previous one where we have introduced a paraconsistent logic termed paraclassical logic to deal with 'complementary propositions'. Here, we enlarge upon the discussion by considering certain 'meaning principles', which sanction either some restrictions of 'classical' procedures or the utilization of certain 'classical' incompatible schemes in the domain of the physical theories. Here, the term 'classical' refers to classical physics. Some general comments on the logical basis of a scientific theory are also put in (...) between the text, motivated by the discussion of complementarity. (shrink)

The editor has assembled these essays to support the thesis that Bergson considered "conceptual revolutions in physics inevitable [and that he foresaw] certain of their most important theoretical consequences." He introduces the collection with an intellectual biography indicating that, far from being antiscientific, Bergson was a respectful and diligent student of science. Several themes illustrative of the thesis run through the selections. One: Bergson's dualisms should be thought of as complementary, for example, intellect and intuition should be regarded as two (...) forms of empiricism rather than as antithetical approaches to knowledge. Another: Bergson anticipated concepts of quantum physics, such as, the dynamic concept of matter and the complementarity of velocity and position. A third theme: Bergson's ideas are suggestive for future scientific investigation, for example, the speed of light may be thought of as a coefficient of equivalence between space and time, a first law of time analogous to the first law of thermodynamics; then Bergson's concepts are perhaps a challenge to develop a second law. Most of the essays, originally published at various times between 1922 and 1959, appear in English for the first time. They are presented in four groups: "Quantum Physics" in which L. de Broglie, S. Watanabe, O. Costa de Beauregard, and R. Blanché are concerned with concepts of motion, entropy, and time; "Relativity" in which appears material by Bergson, Einstein, and Metz on Bergson's criticism of relativity, and essays by G. Pflug, J. F. Busch, W. Berteval, and O. Costa de Beauregard on aspects of Bergson's attack on relativity; "Bergson's and Zeno's Paradoxes" in which D. A. Sipfle uses an analysis of The Arrow by V. C. Chappell to interpret Bergson's theory of time. Milic Capek sums up the volume in an essay arguing that Bergson's concept of psychologic existence, on which his theory of matter is based, suggests a transformation of the basic concepts of the physical sciences. This is a stimulating group of essays, imaginatively edited.--L. G. (shrink)

Explicit, quantitative procedures for identifying biodiversity priority areas are replacing the often ad hoc procedures used in the past to design networks of reserves to conserve biodiversity. This change facilitates more informed choices by policy makers, and thereby makes possible greater satisfaction of conservation goals with increased efficiency. A key feature of these procedures is the use of the principle of complementarity, which ensures that areas chosen for inclusion in a reserve network complement those already selected. This paper sketches (...) the historical development of the principle of complementarity and its applications in practical policy decisions. In the first section a brief account is given of the circumstances out of which concerns for more explicit systematic methods for the assessment of the conservation value of different areas arose. The second section details the emergence of the principle of complementarity in four independent contexts. The third section consists of case studies of the use of the principle of complementarity to make practical policy decisions in Australasia, Africa, and America. In the last section, an assessment is made of the extent to which the principle of complementarity transformed the practice of conservation biology by introducing new standards of rigor and explicitness.

The mental system of an individual usually generates a reality-model that includes a self-model and a world-model as fundamental components. Exceptional experiences (ExE) can be classified as subjectively experienced anomalies in the self-model or the world-model or in the relation of both. Empirical studies show significant correlations between specific patterns of ExE and socially and clinically relevant variables. In order to examine the ontological status of anomalous phenomena a psychophysical approach is presented in which the principle of complementarity is (...) of fundamental importance. Applying a generalized quantum theory to psychosocial and psychophysical systems, complementary aspects such as autonomy versus reliability or novelty versus confirmation are identified as possible local and global variables. The findings indicate that entanglement correlations could play a role in the occurrence of ExE and that specific psychological interventions can dissolve them. (shrink)

Discussions of the interpretation of quantum theory are at present obstructed by (1) the increasing axiomania in physics and philosophy which replaces fundamental problems by problems of formulation within a certain preconceived calculus, and (2) the decreasing (since 1927) philosophical interest and sophistication both of professional physicists and of professional philosophers which results in the replacement of subtle positions by crude ones and of dialectical arguments by dogmatic ones. More especially, such discussions are obstructed by the ignorance of both opponents, (...) and also defenders of the Copenhagen point of view, as regards the arguments which once were used in its defence. The publication of Bunge's Quantum Theory and Reality and especially of Popper's contribution to it are taken as an occasion for the restatement of Bohr's position and for the refutation of some quite popular, but surprisingly naive and uninformed objections against it. Bohr's position is distinguished both from the position of Heisenberg and from the vulgarized versions which have become part of the so-called "Copenhagen Interpretation" and whose inarticulateness has been a boon for all those critics who prefer easy victories to a rational debate. Einstein's main counterargument is discussed, and Bohr's refutation restated. The philosophical background and earlier forms of Bohr's views are stated also. Considering that these views are more detailed, better adapted to the facts of the microdomain than any existing alternative it follows that fundamental discussion must first return to them. Their uniqueness is not asserted, however. Here the author still maintains that a hundred shabby flowers are preferable to a single blossom, however exquisite. But a hundred shabby flowers plus an exquisite blossom are more desirable still. (shrink)

We discuss the multiple pass interferometer setup proposed by Unruh, and clarify some of the fundamental issues linked with complementarity. We explicitly state all mathematical instructions for manipulating the quantum amplitudes and assessing the probability distribution functions. In this respect we show that certain purely math logical limitations (requirement for consistency) prevent one to argue that there is one-to-one corespondence between paths 1 and 2 and the exit gates 10 and 9 ("which way" interpretation), and at the same time (...) insist on pure state density matrix, i. e. existent nonmeasured interference in the second building block of Unruh's interferometer. Furthermore one cannot even argue that Unruh's setup is described by mixed density matrix that keeps the one-to-one correspondence between the paths 1 and 2 and the exit gates. This last claim is mathematically consistent, however is experimentally disprovable - because one may potentially distinguish mixed quantum state from pure quantum state. One just lets the two beams captured at the exit gates cross each other. If interference can be observed the two exit gates were coherent and provide beams in pure state (superposition), while if interference cannot be observed, the state of the exit gates was mixed one. Since the captured beams at the exit gates in Unruh's experiment could interfere this implies that the whole setup is characterized with pure state density matrix and does not preserve the one-to-one correspondence between the entry points and exit gates, even in case where the destructive interference in arm 5 of the interferometer is not measured. Therefore the correct (experimentally plausible and mathematically consistent) exposition of complementarity introduced by Georgiev in 2004 is that Unruh's setup is characterized by pure state density matrix and does not keep the suggested by Unruh one-to-one correspondence. As an appendix is shown the equivalence between Unruh's setup and Afshar's setup and correct analysis of Afshar's experiment is also provided. (shrink)

An idea which, like the Sun, brings out diffused things and facts from the darkness of fragmentary, in a sense undeveloped and almost empty existence and the absurdity of mutually-destructive objects, events and people.Yes—this idea is a path leading away from absurdity and the logical, or, rather, ontological partiality and particularism (hence, in a sense, social meaninglessness) of mutually-destructive and mutually-degrading “incomplete existences”.It is, of course, no new idea—it is present in the history of philosophy, anthropology and biology, and in quantum mechanics: complementarity. However, thanks to the penetrating visions of George McLean, this idea now appears in a new role—putting it most simply (if somewhat impoverishingly): as an instrument enabling comprehension of society, including human relations, over history. This, however, will only be possible if we rise above fact—and even regularity—towards the essence of life and history in their most all-embracing sense. In other words, towards the essence of existence, history and the world. And the key to this will be our understanding and application of complementarity.Complementarity in the here-proposed understanding emerges from the historical process and historical theory as a unique form of maturity, a synthesis bearing the most precious intellectual and moral values for all sides involved in co-creating it.

In 2002, Yorioka introduced the σ-ideal ${{\mathcal {I}}_f}$ for strictly increasing functions f from ω into ω to analyze the cofinality of the strong measure zero ideal. For each f, we study the cardinal coefficients (the additivity, covering number, uniformity and cofinality) of ${{\mathcal {I}}_f}$.

“Bohr was primarily a philosopher, not a physicist, but he understood that natural philosophy... carries weight only if its every detail can be subjected to the... test of experiment”. As a result his approach differed from that of the school-philosophers whom he regarded with a somewhat “sceptical attitude, to say the least” and whose lack of interest in “the important viewpoint which had emerged during the development of atomic physics” he noticed with regret. But it also differed, and to a (...) considerable degree, from the spirit of what Professor T. S. Kuhn has called a “normal science.” Looking at Bohr's method of research we see that technical problems, however remote, are always related to a philosophical point of view; they are never treated as “tiny puzzles” whose solution is valuable in itself, even if one has not the faintest idea what it means, and where it leads: “For me” Bohr writes to Sommerfeld in 1922 “[the quantum theory] is not a matter for petty didactic details, but a serious attempt to reach... an inner coherence.” Emphasis is put on matters of principle and minor discrepancies, or “puzzles” in the sense of Kuhn, instead of being deemphasized, and assimilated to the older paradigm, are turned into fundamental difficulties by looking at them from a new direction, and by testing their background “in its furthest consequences by exaggeration”. A noteworthy example of Bohr's “non-normal” and rather metaphysical approach to physics is his scepticism in the face of the success of his own atomic model. (shrink)

The term complementarity plays a central role in quantum physics, not least in various approaches to defining entanglement and the conditions for its occurrence. It has, however, been used in a variety of ways by different authors, denoting different concepts and relationships.

O experimento de Afshar foi proposto recentemente como sendo uma violação do princípio de complementaridade. Reconhecendo a novidade trazida pelo experimento, argumentamos que ele permite um refinamento de tal princípio, a partir do estabelecimento de dois pontos: (1) a possibilidade de modificar o "tipo" de fenômeno (onda ou partícula) sem alterar o estado quântico, e (2) a constatação de que o tipo de fenômeno, associado a um quantum detectado, refere-se a um trecho determinado percorrido pelo objeto quântico. O primeiro ponto (...) é explorado em interferômetros de Mach-Zehnder, com dispositivos de polarização e na montagem dupla de Unruh. O segundo ponto salienta que um fenômeno pode ser corpuscular com respeito a uma região e ondulatório com respeito a outra, estando a novidade de Afshar na proposta de uma maneira de constatar ambos simultaneamente. A restrição (1) acaba tendo um efeito desprezível no experimento de Afshar. Afshar's experiment was recently proposed as a violation of the principle of complementarity. Acknowledging the novelty brought by the experiment, we argue that it allows a refinement of this principle, with the establishment of two points: (1) the possibility of modifying the "type" of phenomenon (wave or particle) without changing the quantum-mechanical state, and (2) the recognition that the type of phenomenon, associated to a detected quantum, refers to a specific region traversed by the quantum object. The first point is explored in Mach-Zehnder interferometers, with polarization devices and in Unruh's double setup. The second point emphasizes that a phenomenon can be corpuscular with respect one region and undulatory with respect to another. Afshar's originality lies in his proposal of a way of ascertaining both simultaneously. Restriction (1) turns out having a negligible effect in Afshar's experiment. (shrink)

The existing literature on savings, insurance, and portfolio choices under risk has revealed that quite often comparative statics results depend, among other things, upon the values of the coefficients of relative risk aversion and relative prudence. More specifically the benchmark values for these coefficients are, respectively, one and two. Recently, several papers investigated constraints on the higher degree extensions of the coefficients of relative risk aversion and of relative prudence. The present work provides a unified approach to this question based (...) on the concept of elementary correlation increasing transformations, allowing for a better understanding of changes in risk in the multiplicative case.

Of all the developments in twentieth century physics, none has given rise to more heated debates than the changes in our understanding of science precipitated by the quantum revolution''. In this revolution, Niels Bohr's dramatically non-classical theory of the atom proved to be the springboard from which the new atomic physics drew it's momentum. Furthermore, Bohr's contribution was crucial not only because his interpretation of quantum mechanics became the most widely accepted view but also because in his role as educator (...) and spokesman for atomic physics Bohr was very much the patron spirit of the entire quantum revolution. The conceptual framework which he proposed to provide a new viewpoint for understanding the quantum theoretical description of atomic systems became for most of this century the dominant outlook of countless productive experimental and theoretical physicists. He called this new framework complementarity''. (shrink)

Summary. We discuss a specific way in which the notion of complementarity can be based on the dynamics of the system considered. This approach rests on an epistemic representation of system states, reflecting our knowledge about a system in terms of coarse grainings (partitions) of its phase space. Within such an epistemic quantization of classical systems, compatible, comparable, commensurable, and complementary descriptions can be precisely characterized and distinguished from each other. Some tentative examples are indicated that, we suppose, would (...) have been of interest to Pauli. (shrink)

Es wird der Nachweis versucht, dass es — ebenso wie in der Physik — auch in der Biologie komplementäre Erkenntnissysteme gibt. Wie Welle und Korpuskel in der Physik, so sind innerhalb der Biologie u.a. Form und Funktion, Innenwelt und Umwelt sowie auch vor allem Vererbung und Anpassung komplementäre Begriffsgefüge. Das wird im einzelnen diskutiert und nachgewiesen.Für die Erkenntnis der Wirklichkeit im Ganzen folgt daraus, dass systematisch aufgebaute Erkenntnisgefüge nur in Teilbereichen des Wirklichen möglich sind — nur in der klassischen Mechanik, (...) der Elektrodynamik, der vergleichenden Anatomie, der Genetik usw. — Das Wirkliche in seiner Gesamthet hingegen besitzt keine systematische sondern nur eine historisch-dialektische Struktur. Metaphysisch bedeutet das, dass das Wesen der Wirklichkeit in schöpferischer Freiheit im Sinne etwaGoethes, aber nicht in sturer Notwendigkeit besteht.Se demuestra que — como en laFisica — tambien en la Biologia existen complementarios sistemas de conocimiento. Como onda y corpúsculo dentro de la Fisica, asi son dentro de la Biologia entre otros forma y función, mundo internoy ambientey en primer lugar también herencia y adaptación principios complementarios.

Lo real en su totalidad posee al contrario ninguna estructura sistemática sino solo un históricadialectica. Metafisicamente hablado significa esto que la esencia de la realidad consiste en una libertad creativa en el sentido deGoethe, pero de ninguna manera en una necesidad absoluta en el sentido deSpinoza.

Can gene editing and agroecology be complementary? Various formulations of this question now animate debates over the future of food systems, including in the UN Committee on World Food Security and at the UN Food Systems Summit. Previous analyses have discussed the risks of gene editing for agroecosystems, smallholders, and the concentration of wealth by and for agro-industry. This paper takes a different approach, unpacking the epistemic, socioeconomic, and ontological politics inherent in complementarity. I ask: How is complementarity (...) understood? Who is asking and defining this question? What are the politics of entertaining the debate at all? I sketch the epistemic foundations of science and technology that organize different notions of evidence used in agroecology and genetic engineering. On this base, I offer 8 angles on the compatibility question, exploring the historical contradictions that complementarity discourses reveal and the contemporary work they do. I work through questions of technological neutrality, “root cause” problems, working with nature, encoding racism, and dilemmas of ownership and access. These questions, I argue, require a reckoning with ontologies of coloniality-modernity, which help us get underneath—and beyond—the complementarity question. Finally, I offer a framework for thinking about and working toward technology sovereignty. (shrink)

I argue that quantum optical experiments that purport to refute Bohr’s principle of complementarity fail in their aim. Some of these experiments try to refute complementarity by refuting the so called particle–wave duality relations, which evolved from the Wootters–Zurek reformulation of BPC. I therefore consider it important for my forgoing arguments to first recall the essential tenets of BPC, and to clearly separate BPC from WZPC, which I will argue is a direct contradiction of BPC. This leads to (...) a need to consider the meaning of particle–wave duality relations and to question their fundamental status. I further argue that particle and wave complementary concepts are on a different footing than other pairs of complementary concepts. (shrink)

The ArgumentThe aim of this paper is to provide a critical perspective for Einstein's opposition to the Copenhagen interpretation of quantum physics, by analyzing the ingenious rhetoric of Bohr's principle of complementarity. I argue that what Bohr presents as arguments of “inevitability” are in fact merely arguments for the consistency of the quantum-mechanical scheme. Einstein's resistance to being persuaded by this potent technique of argumentation, and his rejection of Bohr's interpretation of quantum physics, appear consequently as an eminently reasonable (...) position and not as a conservative stand, as it is often presented by the adherents of the Copenhagen orthodoxy.
