"For example, I have not disputed the thesis that the physical world is causally closed or that behavior can be explained in physical terms; however, if a physicist or cognitive scientist believes that consciousness can be explained in physical terms, then this is nothing more than a hope unfounded by modern theories, and the question remains open. In general, I have tried to make my ideas compatible with modern science, but at the same time have not limited myself to ideas popular among contemporary scientists." David J. Chalmers - "The Conscious Mind". In Search of a Fundamental Theory. P.S.: Causal closure of the physical world is a philosophical principle stating that every physical event has an exclusively physical cause. According to this concept, the physical world is a self-sufficient system in which no event can be caused by non-physical forces (e.g., the soul or an immaterial mind). Main aspects of the concept: Perfection principle: For every physical event, there exists a sufficient physical cause that explains its occurrence. Exclusion of the "spiritual": No non-physical factor can influence matter or change the course of a physical process. The problem of mental causality: If consciousness is immaterial, how can it control the body (for example, move an arm)? The closure principle denies this possibility. Free will: A paradox arises: if all processes in the brain are rigid physical chains, then free will may be merely an illusion. Physics and epistemology: Debates about whether scientists themselves violate this principle when they deliberately design experiments to understand the laws of nature.
