Materialism: Many neuroscientists and philosophers adopt a materialist perspective, which asserts that consciousness is an emergent property of the brain. According to this view, all aspects of consciousness, including thoughts, perceptions, and emotions, can be explained by the physical and chemical processes that occur in the brain. Materialists argue that understanding the brain's workings will ultimately lead to a complete understanding of consciousness
Dualism: Dualism, as proposed by René Descartes, posits that consciousness and the physical brain are two distinct substances. While the brain is a material entity, consciousness is non-material and interacts with the brain in some way. This view suggests that consciousness cannot be entirely reduced to brain functions and may involve non-physical aspects.
Panpsychism: Panpsychism is a theory that suggests consciousness is a fundamental aspect of the universe, and all matter has some form of consciousness. In this view, even subatomic particles have some rudimentary form of subjective experience. The brain, therefore, organizes and integrates these fundamental consciousness elements into our subjective experience.
Idealism: Idealism is a philosophical view that suggests that consciousness is primary and that the physical world, including the brain, is a manifestation of consciousness. In this view, the material world is, in a sense, a product or projection of the mind.
Of the four mentioned perspectives Materialism is the most logical explanation. Dualism relies on the existence of the supernatural which has no evidence. Extraordinary claims need extraordinary evidence and therefore can be dismissed. Panpsychism should not be viewed as a supernatural process but as an emergent one. This emergent process, which we observe in biological as well as non-biological processes and defined as “having properties as a whole that are more complex than the properties contributed by each of the components individually” is the fundamental aspect of the universe mentioned in Panpsycism and that even subatomic particles have some rudimentary form of subjective experience. We should therefore regard evolution to be starting at the beginning of our universe as a continuing process where abiogenesis is an emergence in the evolutionary process and not a special event. I already mentioned the publication of a new study in my previous blog about “the missing Law” by the prestigious National Academy of Science (see ‘source’ below) which indicates a similar hypothesis. Idealism is a philosophical view without evidence and therefore can be dismissed as well.
The question of whether consciousness is a material brain function or involves non-material aspects remains a topic of ongoing research and debate. While much progress has been made in understanding the neural correlates of consciousness and how brain processes are associated with subjective experience, a complete and universally accepted theory of consciousness is still elusive. The nature of consciousness is a fundamental and complex problem in both philosophy and neuroscience.

Proceedings of the National Academy of Sciences of the United States of America (often abbreviated PNAS or PNAS USA) is a peer-reviewed multidisciplinary scientific journal. It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters. According to Journal Citation Reports, the journal has a 2021 impact factor of 12.779.[1] PNAS is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008 to 2018.[2] In the mass media, PNAS has been described variously as "prestigious",[3][4] "sedate",[5] "renowned"[6] and "high impact".[7]
