The present study is concerned with the problem of realism in quantum mechanics. Contrary to the prevailing view that quantum mechanics forces us to abandon the concept of realism and reality, the author attempts to substantiate another standpoint. Quantum objects indeed exist in a different way from classical bodies. Before the act of measurement begins, one cannot attribute any specific properties to the quantum object observed, as they only occur in the course observation. The concept of observation, however, should not be interpreted as the inclusion of subjective traits in the description of nature. Observation records processes in space and time and establishes the fact of transition from the potential to the reality. The potential is described by a wave function, which in its meaning does not fall in the habitual space and time, whereas the actual is described in terms of a reduction of the wave function, i.e. the transition from a range of possible states to the single one, the observed. Whatever has been observed, in contrast, already belongs to ordinary space and time and can be detected. What follows is that, in quantum mechanics, it is the notion of reality which needs to be reconsidered, not the realism as such rejected. A reconsideration of this sort is conducted here within the framework of a double-modus picture of reality including both potential and actual being, where the quantum level of existence is distinguished from the observed modi of being as described by means of classical concepts. Such a scheme can be described in terms of Aristotelian metaphysics (the fact first pointed out by Heisenberg). The act of transition from potential to actual can be accounted for both in the language of Aristotle’s metaphysics and the language of modern science. In traditional metaphysics it is called the 'principle of individuation', while in modern science it is known as the extended Mach principle. It is argued that the development of these ideas leads to the rejection of Cartesian paradigm in which the existence of a material object always means an existence in space and time.

I suggest a contextual realist interpretation of Carlo Rovelli’s relational quantum mechanics. The principal point is a correct understanding of the concept of reality and taking into account the categorical distinction between the ideal and the real. Within my interpretation, consciousness of the observer does not play any metaphysical role. The proposed approach can also be understood as a return to the Copenhagen interpretation of quantum mechanics, corrected within the framework of contextual realism. The contextual realism allows one to get rid of the metaphysical problems encountered by various interpretations of quantum mechanics, including the relational one. A wave function neither literally reflects an “exterior reality”, nor is it merely a predictive mathematical tool. In particular, an entangled wave function can be viewed as the formal cause of quantum correlations whose reality is contextual. The reduction of a wave function is not a real physical process. And there are no autonomous quantum events which would be different from the facts of their representation. The quantum measurement problem results from a confusion between the categories of the ideal and the real. It is dissolved logically. The quantum theory plays the role of a Wittgensteinian rule (norm), “measuring” physical reality within a language game of its application.
This article is a continuation of the previous one, published in this journal under the same title. The article continues the theoretical consideration of signs of the unity of transcendental psychology (TP) and quantum mechanics (QM) in the vision of Aristotle's metaphysics. In the context of the metaphysical triad necessary-possible-real, the «intersection points» of A. I. Mirakyan’s transcendental psychology and the interpretation of quantum mechanics by A. Yu. Sevalnikov. It is shown that in the both transcendental psychology and quantum mechanics epistemological problems are associated with the impossibility of using the language of their classical predecessors. In both sciences, it becomes necessary to use a new language, a new way of thinking and a new logic of understanding the phenomena under study. All this allows us to conclude that both in transcendental psychology and in quantum mechanics, researchers are dealing with a new ontology of reality that differs from that studied in classical physics and in the phenomenology of classical psychology. It became necessary to divide reality into observable and unobservable. This allows us to say that we are talking about polyontic (or modal) philosophy – different modalities or modes of being, within the framework of which it is necessary to consider the relationship between the necessary, the possible and the real things. Both sciences are the sciences of becoming. If QM is the science of the formation of the observed world, then TP is the science of the generation of phenomena of psychical reality. This is one of the reasons for the unity of their methodological foundations. There is a fairly close similarity in the understanding of the concept of «coexisting opportunities» (or «potential opportunities»). In TP, it coincides with the concept of the coexistence of functionally equal opportunities for reflecting various concomitant properties of objects, and in QM – with the principle of superposition of states of elementary particles. The relative nature of the formation of the phenomenon in the reality of the real follows it. In TP, this is expressed in the realization of one of the coexisting possibilities of reflecting any of the presented properties of the object, and in QM this is expressed as a result of the reduction of the wave function to one of the possible states of a quantum object. The relativity of the formation of a specific phenomenon, determined by the existence of «coexisting possibilities», is realized according to the principle of relativity to the means of observation.
Since the beginning of the XXI st century, there has been a process of intense convergence and interpenetration of two seemingly opposing sciences – quantum mechanics and psychology. In accordance with it, the question arises about a common methodological foundation for these sciences. The article shows that the “first philosophy” of Aristotle can serve as a general philosophical methodology for these sciences. In the context of the metaphysical triad necessarypossible-real, the “intersection points” of A. I. Mirakyan’s transcendental psychology and A. Yu. Sevalnikov’s interpretation of quantum mechanics. The article examines the features of the formation of a new direction in modern psychology, which studies the problem of mental phenomena generation. At the same time, a comparison is made with the transcendentalism of Descartes, in which its limitations and incompleteness are revealed. It is shown that both in transcendental psychology and in quantum mechanics (W. Heisenberg) epistemological problems arise associated with the impossibility of using the language of their classical predecessors. In both sciences, it becomes necessary to apply a new language, a new way of thinking and a new logic of understanding the phenomena under study. All this allows us to conclude that both in transcendental psychology and in quantum mechanics, researchers are dealing with a new ontology of reality that differs from the reality studied in classical physics and in the phenomenology of classical psychology. The article substantiates that the main methodological reason limiting the possibilities of carrying out theoretical studies of deeper layers of reality is the use of the product (physical) approach. The product approach is based on the language used to describe the observed reality. It became necessary to divide reality into observable and unobservable. In the language of metaphysics of modalities, this is translated as «being in possibility» and «being in reality.» One of the “intersection points” of quantum mechanics and transcendental psychology is the category ofpossibility, in which the essence of reality is expressed, which both disciplines compared in this article seek to describe and explain
In this article we discuss the problem of finding an interpretation of quantum mechanics which provides an objective account of physical reality. In the first place we discuss the problem of interpretation and analyze the importance of such an objective account in physics. In this context we present the problems which arise when interpreting the quantum wave function within the orthodox formulation of quantum mechanics. In connection to this critic, we expose the concept of 'entity' as an epistemological obstruction. In the second part of this paper we discuss the relation between actuality and potentiality in classical and quantum physics, and continue to present the concept of 'ontological potentiality' which is distinguished from the generic Aristotelian notion of potentiality in terms of 'becoming actual'. In this paper our main aim is to provide an objective interpretation of quantum mechanics which allows us to discuss the meaning of physical reality according to the theory. For this specific propose we present the concept of 'faculty' in place of the concept of 'entity'. Within our theory of faculties, we continue to discuss and interpret two paradigmatic experiments of quantum mechanics such as the double-slit and Schrodinger's cat.
Quantum mechanics has maintained over the years the reputation of being "the most obscure theory." It works perfectly well, but nobody seems to know why. It has been argued that the difficulty in understanding quantum theory is our failed attempt to force onto it a wrong conceptual scheme, wanting at all costs to think about the objects of the theory as, precisely, objects, i.e., entities having continuously actual spatiotemporal properties. This too restrictive spatiotemporal scheme is most probably at the heart of the problem, as also underlined by the Einsteinian revolution, but then what could be an alternative? Many thinkers have suggested that we must surrender to the fact that our physical world is one of immanent powers and potencies. Aristotle did so ante quantum litteram, followed by scholars like Heisenberg, Primas, Shimony, Piron, Kastner, Kauffman, de Ronde, just to name a few, including the authors, who were both students of Piron in Geneva. However, if on the one hand a potentiality ontology puts the accent on the processes of change, responsible for the incessant shifts between actual and potential properties, on the other hand it does not tell what these changes are all about. In other words, the metaphysical question remains of identifying the nature of the bearer of these potencies, or potentialities, and of the entities that can actualize them. It is the purpose of the present article to emphasize that the above question has found a possible answer in the recent Conceptuality Interpretation of Quantum Mechanics, which we believe offers the missing ontology and metaphysics that can make the theory fully intelligible, and even intuitive.
Quantum mechanics has always presented a problem for scientific realists. For it does not seem to offer a coherent picture of the world. I think it does, and that there is a viable quantum mechanical model of reality. But it cannot be constructed, given the continuity constraints that we usually place on realistic models. To be a quantum mechanical realist, one has to be willing to accept that there are two fundamentally different kinds of processes occurring in nature: continuous, but quantum mechanically indeterminate, energy transfer processes and discontinuous, but spatially extended, changes of state. The unwillingness of philosophers to accept that there is such a distinction has caused many of them to doubt the reality of Schrödinger waves, and the processes of their generation and collapse. I am fully aware that I am treading on well-trodden territory, and that the technical difficulties that must be faced by anyone who is not a specialist in the field are immense. Nevertheless, I think there is a fairly clear metaphysical position on these issues derivable from the kind of essentialist realism outlined in the previous chapter, and I ask readers to bear with me. First, realism about Schrödinger waves requires the belief that particles are always transmitted as quantum mechanically indeterminate waves, but always act as classically determinate particles on whatever absorbs them. The probability of absorption by a given absorbing object (e.g. measuring instrument) at a given location is determined by the value of the Ψ-function at this point.
