Topological Geometro Dynamics Inspired Theory of Consciousness

Abstract

TGD inspired theory of consciousness relies on two fundamental identifications. The identification of quantum jump between quantum histories as a moment of consciousness reduces quantum measurement theory to fundamental physics and solves long list of paradoxes of modern physics. The identification of self as a subsystem able to remain unentangled in subsequent quantum jumps provides a quantum theory of observer and one can identify self also as a fundamental statistical ensemble. The generalization of spacetime concept so that it allows both real and p-adic regions, is a crucial prequisite for the notion of self. Quantum jump between quantum histories decomposes into three parts corresponding to the unitary U process of Penrose followed by the TGD counterpart of state function reduction in turn followed by a cascade of self-measurements giving rise to the TGD counterpart of state preparation. The dynamics of self-measurement is determined by the so-called Negentropy Maximization Principle (NMP). Selves form a hierarchy and self experiences its subselves as mental images and is in turn a mental image of a higher-level self. Selves can have common subselves and this makes possible fusion and sharing of mental images. The experience of self is a statistical average over quantum jumps occurred after the last 'wake-up' and the theory of qualia can be formulated in terms of statistical physics. Self experiences the subselves of subself as a statistical average so that self-hierarchy means also an abstraction hierarchy. Self has as its geometric correlate so called mindlike spacetime sheets of finite duration with respect to the geometric time (as opposed to subjective time determined by the sequence of quantum jumps) and one can understand how psychological time and its arrow emerge. The paradigm of four-dimensional brain provides a completely new view about long-term memories and intentionality. Crucial element behind all these developments are both the classical non-determinism of the fundamental variational principle determining the dynamics of the spacetime surfaces making possible nondeterminism of symbolic representations and the inherent nondeterminism of p-adic differential equations making possible cognitive representations. Together with the nondeterminism of quantum jump these nondeterminisms make possible the self-referentiality of consciousness. Combining this general theory with the notion of manysheeted spacetime one ends up to a vision about biosystems as macroscopic quantum systems and to a rather detailed view about quantum brain.
