Abstract

formalism, which, like propositional dictum, general and unmarked. In this understanding of interpretation, an interpreta tion always an example of more general preexisting truths, an ex emplary part for whole of truth. Moreover, this conception pre serves our common-sense idea of referential function of interpre tation and sign systems more generally: world to language refers preexists (objectively, substantially) language that de scribes it just as necessities of formal logic preexist phenom ena that exemplify those logical necessities. Interpretation, then, con sists of finding a language conforms to preexisting forms. The second concept of interpretation, Greimas and Courtes argue, is completely different. Within this perspective (which they identify with Saussurian linguistics, Husserlian phenomenology and Freudian psychoanalysis—all intellectual movements contemporaneous with quantum theory), no longer a matter of attributing a given to a would otherwise lack one; rather, it a paraphrase formulates in another fashion equivalent con This downloaded from 157.55.39.144 on Wed, 07 Sep 2016 06:27:46 UTC All use to http://about.jstor.org/terms 300 Ronald Schleifer tent of a element within a given semiotic (Semiot ics and Language, 159). In this second understanding of inter pretation, and are not distinct, but rather every form is, alternatively, a semantic content as well, a signifying form, so that offers an analogical paraphrase of something already within a system of signification. Such para phrases are alternatively and different from their model, and as such raise serious questions about referential truth value that seems to govern linguistic dicta and science. That is, alternativeness of paraphrase offers what Jacques Derrida calls without paradigm ...

The opposition between modality and dictum presents just this seriality without paradigm. This espe cially clear in extreme case of negation of modal articulation: negation of a statement taken to be modally inflected—e.g., It not true that atom in left half of box or It not true that multiplication of two negative numbers equals a number—presents metonymic iteration without paradigm, para phrase as Like Heisenberg's between quantum theory and levels of language, this understanding of interpretation presents form of an example, yet, by virtue of fact that what it exempli fies necessarily semanticized, it offers an analogy rather than an example.

Although number i operates like any ordinary number, when apprehended modally—when understood as a paraphrase of \J-1—it alternatively seems to be no number at all. All these difficult definitions and dis tinctions, Heisenberg writes, can be avoided if one confines lan guage to description of facts, i.e., experimental results (Physics and Philosophy, 185). In this, Heisenberg suggesting that as soon as one interprets facts—and elsewhere he defines facts of quan tum mechanics positivistically as the black spots on a photographic plate or water droplets in a cloud chamber (Physics and Philoso phy, 179)—one enters realm of dualism of alternation and paraphrase. Positivism—in facts are assumed to be simple entities like water droplets in a cloud chamber—does not admit negation. The droplets are either present or absent, there or not there, and when they are not there nothing signifies.

These two traditions of interpretation—one classical, other modernist—themselves present a complex double articulation in same way twentieth-century linguistics and Bohr's description of complementarity do. In this complexity, distinction between these traditions not absolute, but rather alternates as a function of questions asked so that interpretation itself remains undecided. Interpretation and understanding, in Emile Benveniste's terms, are cultural phenomena which have characteristic that they never be taken as simple or defined in order of their own na ture but must always be understood as double from fact that they are to something else, whatever their 'referent' may be.27 In an analogical way, nature of data of physics, at least at subatomic scales, cannot simply be defined in order of their own nature. Instead, in same way that even most straight forward, self-evident literal propositions of a sentence—even pure informative (or non-modalized) utterances Greimas and Courtes describe (Semiotics and Language, 10)—can always also be taken to be a figure for something metonymically of them (such as being behind doing, force behind events, very subject articulating propositions that Nietzsche describes), so of quantum physics also always be taken to be connected to something else outside that data: of (modally in flected) knowledge, quality of spatial and temporal position, semiotic system that governs interpretation.

Quantum Mechanics

Peter E. Hodgson

The difficulties of the old quantum theory were largely dispelled by the development of quantum mechanics in the 1920s. First Heisenberg (1925) developed the rather abstract matrix mechanics and soon after Schro¨dinger (1926; see also Eckart, 1926) developed the physically more appealing wave mechanics. Subsequently he showed them to be mathematically equivalent. The physicists were greatly relieved; now they had once again a mathematical formalism that enabled the results of experiments to be calculated. It was possible to move forward. It is certainly a very elegant and indeed beautiful formalism, and does enable the results of many physical measurements to be calculated with great accuracy. It is used daily by atomic and nuclear physicists; there is no other way to make calculations. From the earliest days there has been intense debate about the interpretation of quantum mechanics, and it shows no signs of being settled; if anything it is becoming more intense over the years. As Penrose has remarked, no one understands quantum mechanics. Feynman (1967; see also Sykes, 1994) also admitted that ‘nobody understands quantum mechanics’, and Einstein once remarked: ‘I have thought a hundred times as much about the quantum problems as I have about general relativity theory’ (Pais, 1994, p. 57). It should therefore be evident that the most that can be done here is to try to show where the real difficulties lie, and how the failure to recognize that quantum mechanics is an essentially statistical theory has led to a series of confusing quantum paradoxes. It is just these paradoxes that have often been used to support theological speculations. It is useful to ask what ‘understanding quantum mechanics’ actually means. Certainly it means being able to calculate the results of many measurements. The same applies to Newton’s theory of gravitation, which we understand in the sense that we can use it as a basis of calculation, although we do not really understand the gravitational force itself. Very often, especially in modern physics, the mathematical formalism does not give us the sort of intuitive physical feeling for what is going on that we often obtain from classical mechanics. Perhaps we can never achieve more than this for quantum mechanics. In classical mechanics we can assume that a property that is measured objectively exists prior to the interaction of the measuring apparatus with the observed system. Quantum mechanics, however, ‘is incompatible with the proposition that measurement discovers some unknown but pre-existing property’ (Peres, 1997, p. 14). There is an important distinction between mysteries and absurdities. We may be forced to live with mysteries, but there is no reason why we should put up with absurdities such as the wave-particle duality, tunnelling through potential barriers, acausal events and the collapse of the wave function. These are the quantum paradoxes that will be discussed later on. They arise within the Copenhagen interpretation of quantum mechanics and are solved by other interpretations. These alternative interpretations enable us to make conjectures about what is going on, even though we cannot understand it in detail. This is acceptable and a stimulus to further research. It is certainly difficult enough to understand quantum mechanics, but there is no need to try to visualize logical absurdities in the effort to do so. Quantum mechanics is a mathematical formalism that makes it possible to calculate the results of some experiments. Anything more than this, such as questions about the interpretation of what is measured and whether it tells us what is actually going on in the system being studied, belongs to philosophy. Thus we are concerned here with what is essentially a philosophical debate; if it were just a matter of physics the debate would have been settled long ago. One of the difficulties is that it invokes the results of experiments and uses the language of quantum mechanics. Inevitably this language uses philosophical terms and then it is easy to give the impression that the philosophical propositions are in some way entailed by the physical results. These in turn can influence theological thinking. In order to be quite clear which arguments are justified and which are not, it is essential to separate the three levels of discourse: physical, philosophical and theological. Our task is to relate these together, and this immediately raises the traditional problems of the philosophy of science, including the relation of experiment to theory, and of theory to explanation. We begin by discussing experiments, distinguishing between those that are real and those that are imaginary.

PHILOSOPHY AND QUANTUM PHYSICS

Rom Harr

THE conceptual problems raised by the discovery of quantum effects have not been fully resolved after half a century. Part of the reason for this is undoubtedly to be found in the mutual ignorance which prevails between physicists and philosophers. In his book Heisenberg brings together a philosophically inclined temperament with an unrivalled knowledge of physics. The result is a book of very great interest, however much one might disagree with his conclusions. The collection of essays of which the other book is made up is intended to bring crucial conceptual problems in physics especially to the notice of philosophers. The design and intention of the collection is admirable for this is the proper way to overcome the departmentalization of interest that has left the deep conceptual problems still unresolved. Men like Heisenberg who combine philosophical temperament with scientic knowledge of great distinction are rare, and yet the difficulties can only be cleared up by the application of philosophical techniques of analysis to problems which are an intimate and difficult part of physics. A great deal of the interest of Heisenberg's book lies in the very comprehensive account he gives of the origin and growth of the Copenhagen school, and the way the new phenomena forced a largely unwelcome picture of nature upon Bohr and his friends. The most important chapter from a philosophical point of view is that in which Heisenberg defends this interpretation against the attacks to which it has been subjected. The essence of his argument for the interpretation can be summed up in two propositions. (i) The Copenhagen interpretation of physical theory, which depends upon the acceptance of the so-called Principle of Complementarity, is an inevitable and final interpretation. The reason for this is that there are only two possible general models for understanding given physical phenomena; a particle model or a wave model. These are exhaustive and exclusive because the former depends upon discontinuous and the latter upon continuous (using substance here in the traditional philosophical sense). If we find, as we do, that the two fundamental constituents of the universe, matter and radiation, each exhibit two classes of phenomena, one explainable only on a particle model and one on a wave model, then we are compelled to adopt a complementarity hypothesis and give up the idea of finding a single and uniform model for the understanding of phenomena. There are only two kinds of models; they are mutually exclusive; both are required; hence we either despair before an insoluble problem or adopt the Copenhagen interpretation. (2) Any serious criticism of this interpretation must offer an alternative

Analogy and example: Heisenberg, linguist negation, and the language of quantum physics

Ronald Schleifer

… there is no “being” behind doing, effecting, becoming; “the doer” is merely a fiction added to the deed – the deed is everything. The popular mind in fact doubles the deed; when it sees the lightning flash … it posits the same event first as cause and then a second time as its effect. Scientists do no better when they say “force moves,” “force causes,” and the like – all its coolness, its freedom from emotion notwithstanding, our entire science still lies under the misleading influence of language and has not disposed of that little changeling, the “subject” (the atom, for example, is such a changeling, as is the Kantian “thing-in-itself”) … Friedrich Nietzsche, On the Genealogy of Morals (1969: 45) When Nietzsche speaks of “the misleading influence of language” in The Genealogy of Morals , he is opposing both positivist materialism and idealist subjectivism of the late nineteenth century, the “double deed” – or, in Bruno Latour's terms, “double task of domination and emancipation” (1993: 10) – of Enlightenment understanding examined in part I. He does so through the reconception of time, which Russell describes in relation to post-Newtonian physics, in relation to the eternal recurrence of the same. Nietzsche's method of transforming the settled self-evidence of received opinion does not simply offer other understandings of “force,” “subject,” “atom,” and even the “same” ( das Gleiche ). Rather, he temporalizes understandsing, meaning, and value by bringing together and confronting alternative and alternating discourses.

Quantum mechanics

Marcus Pivato

[M]odern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language. Werner Heisenberg Basic framework Prerequisites: Appendix C, §1B(ii). Near the beginning of the twentieth century, physicists realized that electromagnetic waves sometimes exhibited particle-like properties, as if light were composed of discrete ‘photons’. In 1923, Louis de Broglie proposed that, conversely, particles of matter might have wave-like properties. This was confirmed in 1927 by C. J. Davisson and L. H. Germer and, independently, by G. P. Thompson, who showed that an electron beam exhibited an unmistakable diffraction pattern when scattered off a metal plate, as if the beam were composed of ‘electron waves’. Systems with many interacting particles exhibit even more curious phenomena. Quantum mechanics is a theory which explains these phenomena. We will not attempt here to provide a physical justification for quantum mechanics. Historically, quantum theory developed through a combination of vaguely implausible physical analogies and wild guesses motivated by inexplicable empirical phenomena. By now, these analogies and guesses have been overwhelmingly vindicated by experimental evidence. The best justification for quantum mechanics is that it ‘works’, by which we mean that its theoretical predictions match all available empirical data with astonishing accuracy.

A quantum-based semiotic model for textual semantics

Francesco Galofaro, Zeno Toffano, Bich-Liên Doan

Purpose The paper aims to provide a semiotic interpretation of the role played by entanglement in quantum-based models aimed to information retrieval and suggests possible improvements. Actual models are capable of retrieving documents relevant to a query composed of a keyword and its acceptation expressed by a given context. The paper also considers some analogies between this technique and quantum-based approaches in other disciplines to discuss the consequence of this quantum turn, as epistemology and philosophy of language are concerned. Design/methodology/approach We use quantum geometry to design a formal model for textual semiotics. In particular, the authors refer to Greimas’s work on semantics and information theory, to Eco’s writings on semantic memory and to Lotman’s work on a cybernetic notion of culture. Findings Quantum approaches imply a particular point of view on meaning. Meaning is not a real, positive quality of a given word. It is a net of relations constructed in the text, whose value is progressively determined during the reading process. Furthermore, reading is not a neutral operation: to read is to determine meaning. If it is said that, from a general semiotic point of view, meaning is stored in quantum semantic memories and is read/written by semantic machines, then the operation of “reading/writing” is analogous to the operation of measuring in quantum theory: in other terms, meaning is a value, and this implies an instance (not necessarily human) according to which values are valuable. Research limitations/implications The authors are not proposing a complete quantum semantics. At the present, quantum information retrieval can detect the presence of semantic relations. The authors suggest a way to characterize them, leaving open the problem on how to formalize the document as a vector in four-state semantic space. Practical implications A quantum turn shows deep semiotic implications on the approach to language, which shows an immanent semantic organization not reducible to syntax and morphology. This organization is probabilistic and indeterministic and explains to what extent text fixes the meaning of its lexical units. Social implications In the authors’ perspective, signification is not the exclusivity of a human subject. Criticizing Turing test, the great semiotic and cybernetic scholar Jurij Lotman wrote that if we identify “intelligent” and “human”, we raise the failings of an actual form of intelligence to the rank of an essential characteristic. On this line, meaning is considered as a feature of social, artificial and biological systems. Originality/value The adoption of quantum formalism seems in line with cybernetic framework, involving a probabilistic, non-cartesian point of view on meaning aimed to critically discuss the human–machine relation. Furthermore, Quantum theory (QT) implies a phenomenological point of view on the conditions of possibility of meaning.

In 1923, Louis de Broglie proposed that, conversely, particles of matter might have wave-like properties. This was confirmed in 1927 by C. J. Davisson and L. H. Germer and, independently, by G. P. Thompson, who showed that an electron beam exhibited an unmistakable diffraction pattern when scattered off a metal plate, as if the beam were composed of ‘electron waves’. Systems with many interacting particles exhibit even more curious phenomena. Quantum mechanics is a theory which explains these phenomena. We will not attempt here to provide a physical justification for quantum mechanics. Historically, quantum theory developed through a combination of vaguely implausible physical analogies and wild guesses motivated by inexplicable empirical phenomena. By now, these analogies and guesses have been overwhelmingly vindicated by experimental evidence. The best justification for quantum mechanics is that it ‘works’, by which we mean that its theoretical predictions match all available empirical data with astonishing accuracy.
Purpose The paper aims to provide a semiotic interpretation of the role played by entanglement in quantum-based models aimed to information retrieval and suggests possible improvements. Actual models are capable of retrieving documents relevant to a query composed of a keyword and its acceptation expressed by a given context. The paper also considers some analogies between this technique and quantum-based approaches in other disciplines to discuss the consequence of this quantum turn, as epistemology and philosophy of language are concerned. Design/methodology/approach We use quantum geometry to design a formal model for textual semiotics. In particular, the authors refer to Greimas’s work on semantics and information theory, to Eco’s writings on semantic memory and to Lotman’s work on a cybernetic notion of culture. Findings Quantum approaches imply a particular point of view on meaning. Meaning is not a real, positive quality of a given word. It is a net of relations constructed in the text, whose value is progressively determined during the reading process. Furthermore, reading is not a neutral operation: to read is to determine meaning. If it is said that, from a general semiotic point of view, meaning is stored in quantum semantic memories and is read/written by semantic machines, then the operation of “reading/writing” is analogous to the operation of measuring in quantum theory: in other terms, meaning is a value, and this implies an instance (not necessarily human) according to which values are valuable. Research limitations/implications The authors are not proposing a complete quantum semantics. At the present, quantum information retrieval can detect the presence of semantic relations. The authors suggest a way to characterize them, leaving open the problem on how to formalize the document as a vector in four-state semantic space. Practical implications A quantum turn shows deep semiotic implications on the approach to language, which shows an immanent semantic organization not reducible to syntax and morphology. This organization is probabilistic and indeterministic and explains to what extent text fixes the meaning of its lexical units. Social implications In the authors’ perspective, signification is not the exclusivity of a human subject. Criticizing Turing test, the great semiotic and cybernetic scholar Jurij Lotman wrote that if we identify “intelligent” and “human”, we raise the failings of an actual form of intelligence to the rank of an essential characteristic. On this line, meaning is considered as a feature of social, artificial and biological systems. Originality/value The adoption of quantum formalism seems in line with cybernetic framework, involving a probabilistic, non-cartesian point of view on meaning aimed to critically discuss the human–machine relation. Furthermore, Quantum theory (QT) implies a phenomenological point of view on the conditions of possibility of meaning.
