A recent analysis by de Barros and Suppes of experimentally realizable GHZ correlations supports the conclusion that these correlations cannot be explained by introducing local hidden variables. We show, nevertheless, that their analysis does not exclude local hidden variable models in which the inefficiency in the experiment is an effect not only of random errors in the detector equipment, but is also the manifestation of a pre-set, hidden property of the particles ("prism models"). Indeed, we present an explicit prism model (...) for the GHZ scenario; that is, a local hidden variable model entirely compatible with recent GHZ experiments. (shrink)

In 1935, Einstein, Podolsky, and Rosen (EPR) published an important paper in which they claimed that the whole formalism of quantum mechanics together with what they called a “Reality Criterion” imply that quantum mechanics cannot be complete. That is, there must exist some elements of reality that are not described by quantum mechanics. They concluded that there must be a more complete description of physical reality involving some hidden variables that can characterize the state of affairs in the world in (...) more detail than the quantum mechanical state. This conclusion leads to paradoxical results. -/- As Bell proved in 1964, under some further but quite plausible assumptions, this conclusion that there are hidden variables implies that, in some spin-correlation experiments, the measured quantum mechanical probabilities should satisfy particular inequalities (Bell-type inequalities). The paradox consists in the fact that quantum probabilities do not satisfy these inequalities. And this paradoxical fact has been confirmed by several laboratory experiments since the 1970s. -/- Some researchers have interpreted this result as showing that quantum mechanics is telling us nature is non-local, that is, that particles can affect each other across great distances in a time too brief for the effect to have been due to ordinary causal interaction. Others object to this interpretation, and the problem is still open and hotly debated among both physicists and philosophers. It has motivated a wide range of research from the most fundamental quantum mechanical experiments through foundations of probability theory to the theory of stochastic causality as well as the metaphysics of free will.

On the basis of what I call physico-formalist philosophy of mathematics, I will develop an amended account of the Kantian–Reichenbachian conception of constitutive a priori. It will be shown that the features attributed to a real object are not possessed by the object as a “thing-in-itself”; they require a physical theory by means of which these features are constituted. It will be seen that the existence of such a physical theory implies that a physical object can possess a property only (...) if other contingently existing physical objects exist; therefore, the intrinsic–extrinsic distinction is flawed. (shrink)

A physical theory is a partially interpreted axiomatic formal system, where L is a formal language with some logical, mathematical and physical axioms, and with some derivation rules, and the semantics S is a relationship between the formulas of L and some states of affairs in the physical world. In our ordinary discourse, the formal system L is regarded as an abstract object or structure, the semantics S as something which involves the mental/conceptual realm. This view is of course incompatible (...) with physicalism. How can physical theory be accommodated in a purely physical ontology? The aim of this paper is to outline an account for meaning and truth of physical theory, within the philosophical framework spanned by three doctrines: physicalism, empiricism, and the formalist philosophy of mathematics. (shrink)

I will sketch a possible way of empirical/operational definition of space and time tags of physical events, without logical or operational circularities and with a minimal number of conventional elements. As it turns out, the task is not trivial; and the analysis of the problem leads to a few surprising conclusions.

If physicalism is true, everything is physical. In other words, everything supervenes on, or is necessitated by, the physical. Accordingly, if there are logical/mathematical facts, they must be necessitated by the physical facts of the world. The aim of this paper is to clarify what logical/mathematical facts actually are and how these facts can be accommodated in a purely physical world.

The aim of this paper is to provide an introduction to Fine's interpretation of quantum mechanics and to show how it can solve the EPR-Bell problem. In the real spin-correlation experiments the detection/emission inefficiency is usually ascribed to independent random detection errors, and treated by the “enhancement hypothesis.” In Fine's interpretation the detection inefficiency is an effect not only of the random errors in the analyzer + detector equipment, but is also the manifestation of a pre-settled (hidden) property of the (...) particles. I present one of Fine's 2×2 prism models for the EPR experiment and compare it with the recent experimental results. In the second part of the paper I prove the existence of a wide class of n×n prism models with reasonable detection/emission efficiencies, satisfying the usually required symmetries. Contrary to the common persuasion, the efficiencies in these models do not necessarily tend to zero if n→∞. (shrink)

In classical mechanics, the Galilean covariance and the principle of relativity are completely equivalent and hold for all possible dynamical processes. In relativistic physics, on the contrary, the situation is much more complex: It will be shown that Lorentz covariance and the principle of relativity are not equivalent. The reason is that the principle of relativity actually holds only for the equilibrium quantities characterizing the equilibrium state of dissipative systems. In the light of this fact it will be argued that (...) Lorentz covariance should not be regarded as a fundamental symmetry of the laws of physics. (shrink)

I will argue that the ontological doctrine of physicalism inevitably entails the denial that there is anything conceptual in logic and mathematics. The elements of a formal system, even if they are tagged by suggestive names, are merely meaningless parts of a physically existing machinery, which have nothing to do with concepts, because they have nothing to do with the actual things. The only situation in which they can become meaning-carriers is when they are involved in a physical theory. But (...) in this role they refer to elements of the physical reality, i.e. they represent a physical concept. “Mathematical concepts” are just idols, that philosophy can completely deny and physics can completely ignore. (shrink)

On the basis of what I call physico-formalist philosophy of mathematics, I will develop an amended account of the Kantian–Reichenbachian conception of constitutive a priori. It will be shown that the features attributed to a real object are not possessed by the object as a “thing-in-itself”; they require a physical theory by means of which these features are constituted. It will be seen that the existence of such a physical theory implies that a physical object can possess a property only (...) if other contingently existing physical objects exist; therefore, the intrinsic–extrinsic distinction is flawed. (shrink)

I shall argue that there is no such property of an event as its “probability.” This is why standard interpretations cannot give a sound definition in empirical terms of what “probability” is, and this is why empirical sciences like physics can manage without such a definition. “Probability” is a collective term, the meaning of which varies from context to context: it means different — dimensionless [0, 1]-valued — physical quantities characterising the different particular situations. In other words, probability is a (...) reducible concept, supervening on physical quantities characterising the state of affairs corresponding to the event in question. On the other hand, however, these “probability-like” physical quantities correspond to objective features of the physical world, and are objectively related to measurable quantities like relative frequencies of physical events based on finite samples — no matter whether the world is objectively deterministic or indeterministic.

As a first principle, it is the basic assumption of the standard relativistic formulation of classical electrodynamics (ED) that the physical laws describing the electromagnetic phenomena satisfy the relativity principle (RP). According to the standard view, this assumption is absolutely unproblematic, and its correctness is well confirmed, at least in a hypothetico-deductive sense, by means of the empirical confirmation of the consequences derived from it. In this paper, we will challenge this customary view as being somewhat simplistic. In the majority (...) of cases these results are, in fact, derived merely from the covariance of the corresponding equations, by means of the transformation rules. The RP is actually used in exceptional cases satisfying some special conditions. As we will see, however, it is quite problematic how the RP must be understood in the general case of a coupled particles + electromagnetic field system. (shrink)

Withdrawn by the author! The main content of this paper has been moved into "Szabó, László E., Does special relativity theory tell us anything new about space and time? (ID Code:1321)".

It will be shown that, in comparison with the pre-relativistic Galileo-invariant conceptions, special relativity tells us nothing new about the geometry of spacetime. It simply calls something else "spacetime", and this something else has different properties. All statements of special relativity about those features of reality that correspond to the original meaning of the terms "space" and "time" are identical with the corresponding traditional pre-relativistic statements. It will be also argued that special relativity and Lorentz theory are completely identical in (...) both senses, as theories about spacetime and as theories about the behavior of moving physical objects.

If physicalism is true, everything is physical. In other words, everything supervenes on, or is necessitated by, the physical. Accordingly, if there are logical/mathematical facts, they must be necessitated by the physical facts of the world. In this paper, I will sketch the first steps of a physicalist philosophy of mathematics; that is, how physicalism can account for logical and mathematical facts. We will proceed as follows. First we will clarify what logical/mathematical facts actually are. Then, we will discuss how (...) these facts can be accommodated in the physicalist ontology. This might sound like immanent realism (as in Mill, Armstrong, Kitcher, or Maddy), according to which the mathematical concepts and propositions reflect some fundamental features of the physical world. Although, in my final conclusion I will claim that mathematical and logical truths do have contingent content in a sophisticated sense, and they are about some peculiar part of the physical world, I reject the idea, as this thesis is usually understood, that mathematics is about the physical world in general. In fact, I reject the idea that mathematics is about anything. In contrast, the view I am proposing here will be based on the strongest formalist approach to mathematics. (shrink)

It is widely believed that the principal difference between Einstein's special relativity and its contemporary rival Lorentz-type theories was that while the Lorentz-type theories were also capable of “explaining away” the null result of the Michelson-Morley experiment and other experimental findings by means of the distortions of moving measuring-rods and moving clocks, special relativity revealed more fundamental new facts about the geometry of space-time behind these phenomena. I shall argue that special relativity tells us nothing new about the geometry of (...) space-time, in comparison with the pre-relativistic Galileo-invariant conceptions; it simply calls something else "space-time", and this something else has different properties. All statements of special relativity about those features of reality that correspond to the original meaning of the terms "space" and "time" are identical with the corresponding traditional pre-relativistic statements. It will be also argued that special relativity and Lorentz theory are completely identical in both senses, as theories about space-time and as theories about the behavior of moving physical objects.

While there is a longstanding discussion about the interpretation of the extended, general principle of relativity, there seems to be a consensus that the special principle of relativity is absolutely clear and unproblematic. However, a closer look at the literature on relativistic physics reveals a more confusing picture. There is a huge variety of, sometimes metaphoric, formulations of the relativity principle, and there are different, sometimes controversial, views on its actual content. The aim of this paper is to develop a (...) precise language in order to provide a precise formulation of the principle. In view of the fact that the special relativity principle is considered as a universal meta-law, which must be valid for all physical laws in all situations, we try to keep the formalism as general as possible. The benefit of the formal reconstruction is that it makes explicit all the necessary conceptual components of the principle; it brings out many subtle details and the related conceptual problems.

It is common in the literature on classical electrodynamics and relativity theory that the transformation rules for the basic electrodynamical quantities are derived from the pre-assumption that the equations of electrodynamics are covariant against these---unknown---transformation rules. There are several problems to be raised concerning these derivations. This is, however, not our main concern in this paper. Even if these derivations were completely correct, they leave open the following fundamental question: Are the so-obtained transformation rules indeed identical with the true transformation (...) rules of the fundamental electrodynamical quantities? In other words, is it indeed the case that the values calculated from the quantities in one inertial frame by means of the transformation rules we derived are equal to the values of the same quantities obtained by the same operations with the same measuring equipments when they are co-moving with the other inertial frame? This is of course an empirical question. In this paper, we will investigate the problem in a purely theoretical framework by applying what J. S. Bell calls “Lorentzian pedagogy”---according to which the laws of physics in any one reference frame account for all physical phenomena. We will show that the transformation rules of the electrodynamical quantities are indeed identical with the ones obtained by presuming the covariance of the equations of electrodynamics, and that the covariance is indeed satisfied. Beforehand, however, we need to clarify the operational definitions of the fundamental electrodynamical quantities. As we will see, these semantic issues are not as trivial as one might think.

Greenberger. Horne. Shimony, and Zeilinger gave a new version of the Bell theorem without using inequalities (probabilities). Mermin summarized it concisely; but Bohm and Hiley criticized Mermin's proof from contextualists' point of view. Using the branching space-time language, in this paper a proof will be given that is free of these difficulties. At the same time we will also clarify the limits of the validity of the theorem when it is taken as a proof that quantum mechanics is not compatible (...) with a deterministic world nor with a world that permits correlated space-related events without a common cause.

According to the standard realistic interpretation of classical electrodynamics, the electromagnetic field is conceived as a real physical entity existing in space and time. The problem we address in this paper is how to understand this spatiotemporal existence, that is, how to describe the persistence of a field-like physical entity like electromagnetic field. First, we provide a formal description of the notion of persistence: we derive an “equation of persistence” constituting a necessary condition that the spatiotemporal distributions of the fundamental (...) attributes of a persisting physical entity must satisfy. We then prove a theorem according to which the vast majority of the solutions of Maxwell’s equations, describing possible spatiotemporal distributions of the fundamental attributes of the electromagnetic field, violate the equation of persistence. Finally, we discuss the consequences of this result for the ontology of the electromagnetic field. (shrink)

It is common in the literature on classical electrodynamics and relativity theory that the transformation rules for the basic electrodynamical quantities are derived from the hypothesis that the relativity principle applies to Maxwell's electrodynamics. As it will turn out from our analysis, these derivations raise several problems, and certain steps are logically questionable. This is, however, not our main concern in this paper. Even if these derivations were completely correct, they leave open the following questions: Is the RP a true (...) law of nature for electrodynamical phenomena? Are, at least, the transformation rules of the fundamental electrodynamical quantities, derived from the RP, true? Is the RP consistent with the laws of ED in a single inertial frame of reference? Are, at least, the derived transformation rules consistent with the laws of ED in a single frame of reference? Obviously, and are empirical questions. In this paper, we will investigate problems and. Abstract First we will give a general mathematical formulation of the RP. In the second part, we will deal with the operational definitions of the fundamental electrodynamical quantities. As we will see, these semantic issues are not as trivial as one might think. In the third part of the paper, applying what J. S. Bell calls “Lorentzian pedagogy”---according to which the laws of physics in any one reference frame account for all physical phenomena---we will show that the transformation rules of the electrodynamical quantities are identical with the ones obtained by presuming the covariance of the equations of ED, and that the covariance is indeed satisfied. Abstract As to problem, the situation is much more complex. As we will see, the RP is actually not a matter of the covariance of the physical equations, but it is a matter of the details of the solutions of the equations, which describe the behavior of moving objects. This raises conceptual problems concerning the meaning of the notion “the same system in a collective motion”. In case of ED, there seems no satisfactory solution to this conceptual problem; thus, contrary to the widespread views, the question we asked in the title has no obvious answer. (shrink)

The aim of the paper is to develop a proper mathematical formalism which can help to clarify the necessary conceptual plugins to the special principle of relativity and leads to a deeper understanding of the principle in its widest generality.

This paper proposes a specific approach to understanding the nature of technology that encompasses the entire field of technological praxis, from the making of primitive tools to using the Internet. In that approach, technology is a specific form of human agency that yields to (an imperfect) realization of human control over a technological situation—that is, a situation not governed to an end by natural constraints but by specific human aims. The components of such technological situations are a given collection of (...) natural or artificial beings, humans, human aims, and situation-bound tools. By performing technological situation analysis, the essential form of tool making, the complex system of relationships between science and technology, technological practices with and without machines, the finiteness or imperfectness of any technology, and engineering (i.e., the possibility of the creation of technological situations) can be considered. For a better characterization of the approach to technology, the paper also presents a comparison of other philosophies of technology. Following Feenberg’s comparative analysis, the so-called fundamental question of the philosophy of technology is formulated, its two sides are identified, and it is applied for clarification of our position within philosophy of technology. In our approach, all human praxis can be considered to be technological; more precisely, every human activity has a technological aspect or dimension. (shrink)

A condition is formulated in terms of the probabilities of two pairs of correlated events in a classical probability space which is necessary for the two correlations to have a single (Reichenbachian) common-cause and it is shown that there exists pairs of correlated events probabilities of which violate the necessary condition. It is concluded that different correlations do not in general have a common common-cause. It is also shown that this conclusion remains valid even if one weakens slightly Reichenbach's definition (...) of common-cause. The significance of the difference between common-causes and common common-causes is emphasized from the perspective of Reichenbach's Common Cause Principle. (shrink)

The paper argues for the necessity of building up a philosophy of the Internet and proposes a version of it, an «Aristotelian» philosophy of the Internet. First, an overview of the recent trends in the Internet research is presented. This train of thoughts leads to a proposal of understanding the nature of the Internet in the spirit of the Aristotelian philosophy i. e., to conceive the Internet as the Internet, as a totality of its all aspects, as a whole entity. (...) For this purpose, the Internet is explained in four (easily distinguishable, but obviously connected) contexts: we regard it as a system of technology, as an element of communication, as a cultural medium and as an independent organism. Based on these investigations we conclude that the Internet is the medium of a new mode of human existence created by late modern man; a mode that is built on earlier (i. e., natural, and social) spheres of existence and yet it is markedly different from them. We call this newly formed existence web-life. Finally using two enlightening cultural-historical analogies (the reformation of knowledge and the formation of web-life) several fundamental characteristics of the web-life is presented. (shrink)

The need to establish a research field within psychology didactics at secondary level has recently been voiced by several researchers internationally. An analysis of a Swedish case coming out of secondary level education in psychology presented here provides an illustration that complexity thinking – derived from complexity theory – is uniquely placed to consider and indicate possible solutions to challenges, described by researchers as central to the foundation of a new field. Subject-matter didactics is defined for the purpose of this (...) paper as a combination of general didactics and subject- matter content, and considering the international nature of research traditions coming out of psychology, the implications of the results presented here cannot be regarded as limited solely to national concerns. An on-line survey was sent to secondary schools in Sweden. Discussions and lectures along with teaching to the book – alternatively used as inspiration – emerged as central from the thematic analysis of the results, providing the first mapping of teaching practices in secondary level psychology in Sweden. An analysis, founded on complexity thinking – combined with a model enabling a delimitation of the scope of study – focused on time use and the importance placed on self-knowledge, along with the transformation of theory into practice. The former pointing to a teacher centred nested subsystem (e.g. asymmetric relations between teachers and students), the latter pointing to student centred nested subsystems coming out of embodied knowledge (e.g. students as node) where psychological perspectives are learnt through self-reflexion, case studies and everyday life experiences (turning theory to practice), implying a holistic approach. The analysis applied to the Swedish case provides an illustration of how complexity theory has the potential to address challenges at micro and macro level to the establishment of a new research field in psychology didactics and to indicate possible solutions. Psychologies high relevance to everyday life, multi-causality, perspective pluralism, dynamic systems character and scientific character, makes complexity thinking a relevant approach in the consideration of challenges to the establishment of a research field in didactics of psychology.

The interpretations of sustainability are varied. In most cases, the focus is on reinterpretations and transformations of human attitudes towards the natural environment and certain (unacceptable) social practices and conditions, i.e. the task would be to shape these spheres of human existence in the interests of sustainability. However, the creation and widespread use of the Internet is fundamentally changing human life that is no longer confined to the natural and social spheres. Web life, as a third sphere of human existence (...) created by the universal use of the Internet, is also a component of human condition, both in itself and through its interactions with the natural and social spheres. It is essential to take this into account: the sustainability of these “three spheres” should be addressed together. The continuous construction of web life can be decisive for the sustainability of the whole human existence. (shrink)

The spin geometry theorem of Penrose is extended from SU to E invariant elementary quantum mechanical systems. Using the natural decomposition of the total angular momentum into its spin and orbital parts, the distance between the centre-of-mass lines of the elementary subsystems of a classical composite system can be recovered from their relative orbital angular momenta by E-invariant classical observables. Motivated by this observation, an expression for the ‘empirical distance’ between the elementary subsystems of a composite quantum mechanical system, given (...) in terms of E-invariant quantum observables, is suggested. It is shown that, in the classical limit, this expression reproduces the a priori Euclidean distance between the subsystems, though at the quantum level it has a discrete character. ‘Empirical’ angles and 3-volume elements are also considered.

By extending the underlying data structure by new elements, we also extend the intput/output relation generated by a program i.e., no existing run is killed, and no new one lying entirely in the old structure is created. We investigate this stability property for the weak second order semantics derived from nonstandard time models. It turns out that the light face, i.e., parameterless collection principle always induces stable semantics, but the bold face one may be unstable. We give an example where (...) an elementary extension kills a bold face run showing also that the light face semantics is strictly weaker than the bold face one. (shrink)

Penrose’s Spin Geometry Theorem is extended further, from SU(2) and E(3) (Euclidean) to E(1, 3) (Poincaré) invariant elementary quantum mechanical systems. The Lorentzian spatial distance between any two non-parallel timelike straight lines of Minkowski space, considered to be the centre-of-mass world lines of E(1, 3)-invariant elementary classical mechanical systems with positive rest mass, is expressed in terms of E(1, 3)-invariant basic observables, viz. the 4-momentum and the angular momentum of the systems. An analogous expression for E(1, 3)-invariant elementary quantum mechanical (...) systems in terms of the basic quantum observables in an abstract, algebraic formulation of quantum mechanics is given, and it is shown that, in the classical limit, it reproduces the Lorentzian spatial distance between the timelike straight lines of Minkowski space with asymptotically vanishing uncertainty. Thus, the metric structure of Minkowski space can be recovered from quantum mechanics in the classical limit using only the observables of abstract quantum mechanical systems. (shrink)

La obra de Hans-Dieter Gondek y László Tengelyi, Neue Phänomenologie in Frankreich (2011) ofrece una relectura de los nuevos desarrollos fenomenológicos provenientes de Francia.

The paper sets out to offer an alternative to the function/argument approach to the most essential aspects of natural language meanings. That is, we question the assumption that semantic completeness (of, e.g., propositions) or incompleteness (of, e.g., predicates) exactly replicate the corresponding grammatical concepts (of, e.g., sentences and verbs, respectively). We argue that even if one gives up this assumption, it is still possible to keep the compositionality of the semantic interpretation of simple predicate/argument structures. In our opinion, compositionality presupposes (...) that we are able to compare arbitrary meanings in term of information content. This is why our proposal relies on an ‘intrinsically’ type free algebraic semantic theory. The basic entities in our models are neither individuals, nor eventualities, nor their properties, but ‘pieces of evidence’ for believing in the ‘truth’ or ‘existence’ or ‘identity’ of any kind of phenomenon. Our formal language contains a single binary non-associative constructor used for creating structured complex terms representing arbitrary phenomena. We give a finite Hilbert-style axiomatisation and a decision algorithm for the entailment problem of the suggested system. (shrink)

Science, and with it our understanding of evolutionary processes, is itself undergoing evolution. The evolutionary framework still most frequently used by the general public to describe and guide processes of societal development is erroneously grounded in Darwinian perspectives or, at the very least, draws facile analogies from biological evolution. The present inquiry incorporates fresh insights on the general systemic nature of developmental dynamics from the most recent advances in the transdisciplinary realm of the sciences of complexity (e.g., general evolution theory, (...) cybernetics, information and communication theory, chaos theory, dynamical systems theory, and nonequilibrium thermodynamics). The description of the evolutionary trajectory of complex dynamical systems as irreversible, periodically chaotic, and strongly nonlinear agrees with certain features of the historical processes of societal development. But there are additional features of the evolutionary dynamic of natural systems that are seldom portrayed as part of human developmental deportment. These features include elements such as the convergence of existing systems at progressively higher levels of organization, the increasingly efficient utilization of environmental energy, and the complexification of system structures in states that are progressively further removed from chemical and thermodynamic equilibria. The sciences of complexity offer insight into the laws and dynamics that govern the evolution of complex systems across a variety of disciplinary areas of investigation. Through a study of the isomorphisms across disciplinary constructs in the theoretical analyses of the principles governing the evolution of human societies, it is possible to enrich the account of developmental dynamics at the socio-civilizational level. Such an account would further our understanding of the phenomenon of societal development and provide the means for the purposeful guidance of this phenomenon in accordance with general evolutionary principles. This article sets forth the type of considerations, and outlines a general research agenda, for inquiry toward an operational model of the evolutionary development of social systems. (shrink)

Paradigm-shifts, termed scientific revolutions, occur periodically in the course of science's development The twentieth century witnessed a number of revolutions, first by Albert Einstein and then by Niels Bohr in physics, and subsequently in biology, cosmology and, through the pioneering work of Pierre Teilhard de Chardin, in the transdisciplinary area that includes human mind and consciousness. But scientific development did not come to a standstill: while the spirit of Einstein and Teilhard is as present as ever, their specific theories are (...) subject to the dynamics of theory development through periods of "normal" and "revolutionary" science. Today another revolution is about to occur, bringing science to the threshold of a more comprehensive and integrated account of the observed phenomena. The currently emerging transdisciplinary unified theory is consistent with the goals and vision of both Albert Einstein and Teilhard de Chardin. It penetrates deeper into the domains of reality than the 20th century's mainstream physical, biological and psychological theories did -below the level of the quanta that populate space-time, to the quantum vacuum, better termed cosmic plenum, that generates the quanta and interconnects them throughout space and time. In the twentieth century Einstein's general relativity gave us the relativistically interlinked universe, where all things are connected by signals propagating across the geometric structure of space-time, and Teilhard de Chardin laid the foundations of a unified theory where life and mind emerge consistently out of the physical world. In the twenty-first century transdisciplinary unified theory will extend these conceptions and give us the coherent universe, where all things are intrinsically connected by a fundamental information and virtual-energy field at a fundamental level of physical reality. /// A mudança de paradigmas, a que frequentemente damos o nome de revoluções científicas, ocorrem periodicamente no decurso da evolução científica. O século XX testemunhou uma importante série de revoluções científicas, primeiro por Albert Einstein e depois por Niels Bohr no âmbito da física, e subsequentemente em biologia, cosmo-logia e, graças ao trabalho pioneiro de Pierre Teilhard de Chardin, na área transdisci-plinar que inclui os fenómenos da mente humana e da consciência. Mas o desenvolvimento científico não estagnou: enquanto que o espírito de Albert Einstein e de Teilhard de Chardin continua certamente presente, a verdade é que as suas teorias têm-se necessariamente submetido à dinâmica própria do desenvolvimento das teorias, o que acontece ao longo de períodos de ciência ditos "normais" quer "revolucionários". Segundo o autor do artigo, a humanidade está hoje a ponto de assistir a uma nova revolução, a qual colocará a ciência no limiar de produzir uma narrativa mais compreensiva e integrada dos fenómenos observados. Nesse sentido, a teoria transdisciplinar unificada é perfeitamente consistente com os objectivos e a visão tanto de Albert Einstein como de Teilhard de Chardin. Com efeito, esta teoria penetra mais fundo nos domínios da realidade do que as teorias mais comuns que o século XX produziu seja no domínio da física, da biologia ou da psicologia — passando do domínio dos quanta que povoam o espaço-tempo, para o quantum vacuum, mais precisamente designado plenum cósmico que gera os quanta e os interconecta através do espaço-tempo. No século XX, a teoria da relatividade generalizada de Einstein deu-nos um universo relativisticamente interconectado, no qual todas as coisas estão conectadas por sinais que se propagam através da estrutura geométrica do espaço-tempo. Por seu lado, Teilhard de Chardin lançou os fundamentos de uma teoria unificada em que os fenómenos da vida e da consciência emergem consistentemente do mundo físico. Agora, no século XXI, diz o autor do artigo, a teoria transdisciplinar unificada destina-se a alargar o âmbito destas concepções geniais de modo a dar-nos um universo coerente em que todas as coisas estão intrinsecamente conectadas por uma informação fundamental e um campo energético virtual ao nível mais profundo da realidade física.
