Parallel to David Bohm´s development of a realistic interpretation of quantum physics, German philosopher and logician Gotthard Günther worked on a generalization of the classical two-valued logic to satisfy the ontological requirements of quantum physics as well as of cybernetics. Both of these new disciplines introduced information and consciousness into the terminology of science. These terms and concepts need to be reflected in logic, ontology and the theory of science. David Bohm suggested an expansion of his own model by generalization and iteration of the quantum potential to include consciousness and mental states into a new psycho-physical theory. This article proposes Günther´s four-valued logical system of meaning/reflection as a theoretical scientific frame for this expansion of Bohm´s theory and discusses its ontological implications.

This paper explores the theme “quantum approaches to consciousness” by considering the work of one of the pioneers in the field. The physicist David Bohm (1917-1992) not only made important contributions to quantum physics, but also had a long-term interest in interpreting the results of quantum physics and relativity in order to develop a general world view. His idea was further that living and mental processes could be understood in a new, scientifically and philosophically more coherent way in the context of such a new world view. This paper gives a brief overview of different – and sometimes contradictory - aspects of Bohm’s research programme, and evaluates how they can be used to give an account of topics of interest in contemporary consciousness studies, such as analogies between thought and quantum processes, the problem of mental causation, the mind-body problem and the problem of time consciousness.
This study offers a comprehensive analysis of David Bohm’s article “A New Theory of the Relationship of Mind and Matter” (Philosophical Psychology, 1990) — one of the most original attempts of the twentieth century to overcome Cartesian dualism on a physical foundation. The paper proceeds in sequence through the historical context of the mind–body problem, the physical basis of the causal interpretation of quantum mechanics, the central concept of active information, and the implicate order. Bohm’s framework is then compared with several major contemporary approaches: Orchestrated Objective Reduction (Hameroff & Penrose, 2014), the holographic brain model (Pribram, 1991), Integrated Information Theory (Tononi, 2004), and the Global Workspace model (Baars, 1988; Dehaene, 2014). A dedicated section examines the relationship between Bohm’s ideas and Rovelli’s Relational Quantum Mechanics (Rovelli, 1996), as well as Loop Quantum Gravity (Rovelli, 2004; Rovelli & Smolin, 1995), and Qbism, developed by Christopher Fuchs, Rüdiger Schack, and Carlton Caves (Fuchs, 2002; Fuchs et al., 2014). The concluding section evaluates the compatibility of Bohm’s ideas with quantum field theory and modern quantum information science. The principal conclusion is that Bohm’s 1990 article does not constitute a complete theory of consciousness, yet it anticipates with remarkable prescience the information-ontological tendencies of the twenty-first century and may best be understood as a philosophical-physical metatheory whose relevance has only grown since its publication.
Western philosophy and science have a strongly dualistic tradition regarding the mental and physical aspects of reality, which makes it difficult to understand their possible causal relations. In recent debates in cognitive neuroscience it has been common to claim on the basis of neural experiments that conscious experiences are causally inefficacious. At the same time there is much evidence that consciousness does play an important role in guiding behavior. The author explores whether a new way of understanding the causal role of mental states and consciousness could be provided by the ontological interpretation of the quantum theory (Bohm and Hiley, Phys. Rep. 144:323–348, 1987; Bohm and Hiley, The undivided universe: An ontological interpretation of quantum theory. Routledge: London, 1993). This interpretation radically changes our notion of matter by suggesting that a new type of active information plays a causal role at the quantum level of reality. The author thus considers to what extent the alleged causal powers of consciousness involve information, and then moves on to consider whether information in (conscious) mental states can be connected to the information at the level of quantum physics. In this way he sketches how quantum theory might help to throw light upon one of the grand challenges facing the social sciences and the humanities, namely the question of whether consciousness plays any genuine causal role in the physical world.
Abstract The paper investigates David Bohm’s philosophy of science as a form of fallibilist realism that underpins his causal interpretation of quantum mechanics Bohm (Bohm 1952a, 1952b, 1984, 1985, 1988, 1989, 1990; Bohm and Hiley 1975, 1984, 1993). Bohm’s central aim is to establish the superiority of his interpretation over the standard Copenhagen framework, particularly in contrast to that of Niels Bohr. Whereas Bohr asserts that knowledge of quantum phenomena is restricted to the statistical outcomes of measurement, Bohm’s approach is distinctly realist in orientation. Responding to the challenges posed by Einstein and other physicists, Bohm relies on extra-empirical criteria such as determinism, objectivity and intelligibility. The paper develops what will be termed the methodology of intuitive intelligibility (II), consisting of four stages: (1) reformulation of the standard quantum equations, (2) physical interpretation of the mathematical symbols, (3) drawing analogies with classical laws, and (4) drawing analogies with common experience. It is argued that Bohm applies the (II) methodology consistently, with the notable exception of the ontological status of the wave function and quantum potential. In attempting to explain causal relations from a 3N-dimensional configuration space (where N is the number of particles) to familiar three-dimensional space through an appeal to ‘information’, Bohm arguably commits a category mistake. A proposed resolution—drawing on Bohm’s own holistic analogies—is supported by the recent multi-field interpretation (Romano Multi-field and Bohm’s theory. Synthese, 198(30), 10587–10609, 2021). The term fallibilist realism aptly characterizes Bohm’s stance in the philosophy of science: he repeatedly emphasizes that the causal interpretation is not intended as a final theory. Nevertheless, holism constitutes a substantive ontological commitment that he is unwilling to abandon.
Perhaps more so than any other twentieth-century physicist, David Bohm was trying to develop an ontological interpretation for quantum theory, i.e. an interpretation which tells us what quantum theory says about the nature of reality. He is best known for presenting in 1952 an improved version of de Broglie’s ‘pilot-wave’ theory, which says that an electron is a particle always accompanied by a new type of quantum field or pilot wave which guides it. In later research Bohm realized that the pilot wave is not pushing and pulling the particle mechanically but rather contains information which guides the particle, analogously to the way radar waves guide a ship on autopilot. The postulation of such objective and active information to the quantum level is a radical metaphysical move which also opens a new way to understand how the material and mental sides of reality are related to each other. It might even make it easier to understand what phenomenal properties are and how they could play a causal role in the physical world. This paper provides an overview of not only the pilot-wave theory, but also Bohm’s other related frameworks, namely the implicate order and soma-significance. It is suggested that these views point to a new theory of the relation of consciousness and matter which we can call interactionist dual-aspect monism. This theory suggests, against illusionism, that phenomenal properties exist and, against idealism, that the world has a material aspect which exists independently of the human mind ‐ thus ‘real consciousness in a real world’.
Mainstream cognitive neuroscience typically ignores the role of quantum physical effects in the neural processes underlying cognition and consciousness. However, many unsolved problems remain, suggesting the need to consider new approaches. We propose that quantum theory, especially through an ontological interpretation due to Bohm and Hiley, provides a fruitful framework for addressing the neural correlates of cognition and consciousness. In particular, the ontological interpretation suggests that a novel type of “active information”, connected with a novel type of “quantum potential energy”, plays a key role in quantum physical processes. After introducing the ontological interpretation we illustrate its value for cognitive neuroscience bydiscussing it in the light of a proposal by Beck and Eccles about how quantum tunneling could play a role in controlling the frequency of synaptic exocytosis. In this proposal, quantum tunneling would enable the “self” to control its brain without violating the energyconserv ation law. We argue that the ontological interpretation provides a sharper picture of what actuallycould be taking place in quantum tunneling in general and in synaptic exocytosis in particular. Based on the notions of active information and quantum potential energy, we propose a coherent way of understanding how mental processes (understood as involving non-classical physical processes) can act on traditional, classicallydescribable neural processes without violating the energy conservation law.
