Quantum Panprotopsychism and the Structure and Subject-Summing Combination Problem

Rodolfo Gambini, Jorge A. Pullin

Abstract

In a previous paper, we have shown that an ontology of quantum mechanics in terms of states and events with internal phenomenal aspects, that is, a form of pan-protopsychism, is well suited to explaining consciousness. We have proved there that the palette and grain combination problems of panpsychism and pan-protopsychism arise from implicit hypotheses based on classical physics about supervenience that are inappropriate at the quantum level, where an exponential number of emergent properties and states arise. In this article, we address what is probably the first and most important combination problem of panpsychism: the subject-summing problem originally posed by William James. Due to the indeterminacy of quantum mechanics and its causal openness, this ontology also seems to be suitable for the analysis of the remaining aspects of the structure combination problem that treat about how the structuration capacity of consciousness evolved from primitive animals to humans.

Quantum panprotopsychism and the combination problem

Rodolfo Gambini, Jorge A. Pullin

We will argue that a phenomenological analysis of consciousness, similar to that of Husserl, shows that the effects of phenomenal qualities shape our perception of the world. It also shows the way the physical and mathematical sciences operate, allowing us to accurately describe the observed regularities in terms of communicable mathematical laws. The latter say nothing about the intrinsic features of things. They only refer to the observed regularities in their behaviors, providing rigorous descriptions of how the universe works, to which any viable ontology must conform. Classical mechanistic determinism limits everything that can occur to what happens in an instant and leaves no room for novelty or any intrinsic aspect that is not epiphenomenal. The situation changes with quantum probabilistic determinism if one takes seriously the ontology that arises from its axioms of objects, systems in certain states, and the events they produce in other objects. As Bertrand Russell pointed out almost a century ago, an ontology of events, with an internal phenomenal aspect, now known as panprotopsychism, is better suited to explaining the phenomenal aspects of consciousness. The central observation of this paper is that many objections to panpsychism and panprotopsychism, which are usually called the combination problem, arise from implicit hypotheses based on classical physics about supervenience. These are inappropriate at the quantum level, where an exponential number of emergent properties and states arise. The analysis imposes conditions on the possible implementations of quantum cognition mechanisms in the brain.

Self-consciousness and personal identity in quantum panprotopsychism

Rodolfo Gambini, Jorge A. Pullin

In previous papers, we demonstrated that an ontology of quantum mechanics, described in terms of states and events with internal phenomenal aspects (a form of panprotopsychism), is well suited to explain consciousness. We showed that the combination problems of qualities, structures and subjects in panpsychism and panprotopsychism stem from implicit hypotheses based on classical physics regarding supervenience, which are not applicable at the quantum level. Within this view, consciousness arises in entangled quantum systems coupled to the neural network of the brain. In entangled systems, the properties of individual parts disappear, giving rise to an exponential number of emergent properties and states. Here, we analyze self-consciousness as the capacity to view oneself as a subject of experience. The causal openness of quantum systems provides self-conscious beings the ability to make independent choices and decisions, reflecting a sense of self-governance and autonomy. In this context, the issue of personal identity takes a new form free from the problems of the simple view or the reductive approaches.

Panprotopsiquismo Cuántico y las Interpretaciones de la Mecánica Cuántica

Rodolfo Gambini

Given the multiplicity of interpretations of quantum mechanics that give rise to very different ontologies, it is worth asking whether it is possible to find criteria with some empirical basis that make some interpretations preferable to others. If empirical evidence were found for the existence of quantum systems in the brain such as those necessary to adopt a form of panpsychism that resolves the problems of combination of subjects, qualities, and structures recognized since the time of William James, their underlying ontologies would be favored by allowing us to account for our conscious experiences. Quantum panprotopsychism has proven particularly well-suited to addressing the combination problems of panpsychism. It is based on an ontology of states and events with clearly identified physical and phenomenal counterparts and would therefore be recognizable if these physical elements were part of brain function.. Such an ontology could provide criteria for preferring certain quantum interpretations over others. Here we will analyze the interpretations that would be favored or challenged by the ontology resulting from this form of panprotopsychism.

Pan-protopsychism & the Relative-State Interpretation of Quantum Mechanics

Feng Yu

This paper connects the hard problem of consciousness to the interpretation of quantum mechanics. It shows that constitutive Russellian pan-protopsychism (CRP) is compatible with Everett’s relative-state (RS) interpretation. Despite targeting different problems, CRP and RS are related, for they both establish symmetry between micro- and macrosystems, and both call for a deflationary account of Subject. The paper starts from formal arguments that demonstrate the incompatibility of CRP with alternative interpretations of quantum mechanics, followed by showing that RS entails Russellian pan-protopsychism. Therefore, CRP and RS are mutually supportive. It then provides a unified ontological picture by combining CRP and RS. The challenge faced by CRP, the combination problem, can be resolved by adopting a RS version of quantum mechanics. Technically, this is achieved by a co-consciousness relation capable of explaining the difference between first-person and third-person perspectives. The hierarchical structure of the relation removes any concern on the structural mismatch between the physical and the phenomenal.

Quantum Consciousness and Panpsychism: A Solution to the Hard Problem

Gao Shan

We analyze the results and implications of the combination of quantum and consciousness in terms of the recent QSC analysis. The quantum effect of consciousness is first explored. We show that the consciousness of the observer can help to distinguish the nonorthogonal states under some condition, while the usual physical measuring device without consciousness can’t. The result indicates that the causal efficacies of consciousness do exist when considering the basic quantum process. Based on this conclusion, we demonstrate that consciousness is not reducible or emergent, but a new fundamental property of matter. This provides a quantum basis for panpsychism. Furthermore, we argue that the conscious process is one kind of quantum computation process based on the analysis of consciousness time and combination problem. It is shown that a unified theory of matter and consciousness should include two parts: one is the complete quantum evolution of matter state, which includes the definite nonlinear evolution element introduced by consciousness, and the other is the psychophysical principle or corresponding principle between conscious content and matter state. Lastly, some experimental suggestions are presented to confirm the theoretical analysis of the paper. Key words: quantum process, consciousness, distinguish the nonorthogonal states, causal efficacies of consciousness, fundamental property of matter, panpsychism, quantum computation, definite
