Matter, Mind and the quantum
Topological Geometro-Dynamics (TGD) is a unified theory of fundamental interactions. TGD involves a quite far-reaching generalization of the space–time concept and, apart from the notion of quantum jump, reduces quantum theory to infinite-dimensional geometry. General coordinate invariance forces the identification of the quantum states as quantum histories rather than time-constant snapshots of a single quantum history: this solves the basic determinism/non-determinism paradox of quantum measurement theory. The identification of the quantum jump as a moment of consciousness defines the microscopic theory of consciousness. p-Adic numbers is one of the basic new mathematical concepts necessary for the formulation of quantum TGD. The notion of the self as a subsystem remaining p-adically unentangled under the action of the “time evolution” operator U (S-matrix) associated with the sequential quantum jumps Ψ<sub>i</sub> UΨ<sub>i</sub> Ψ<sub>f</sub> is central for the macroscopic theory of consciousness. Vanishing p-adic entanglement means subcritical real entanglement so that the self can be regarded as a critical phenomenon. The moments of consciousness which occurred after the last “wake-up” bind temporally to a single experience and give rise to immediate subjective memory. Each self represents a self-organizing system approaching a stable self-organization pattern selected by dissipation. A self can have sub-selves and experiences sub-selves as mental images which are averages about mental images of sub-sub-selves. An infinite hierarchy of selves giving rise to an abstraction hierarchy is predicted. The notion of the manysheeted spacetime and the classical non-determinism of the Kähler action defining configuration space geometry are crucial for understanding how psychological time and cognition emerge in the TGD-universe and a rather radical generalization of the views about the relationship of subjective and geometric time is forced.
