“If the existence of consciousness cannot be derived from physical laws, a theory of physics is not a true theory of everything. So a final theory must contain an additional fundamental component. Toward this end, I propose that conscious experience be considered a fundamental feature, irreducible to anything more basic.”
This perception of the central nature of consciousness to the cosmological description is more acute than an academic or philosophical matter. Although the scientific description is based exclusively on the objective physical universe, our contact with reality is entirely sine qua non through our subjective conscious experience. From birth to death, we experience only a stream of consciousness through which all our experience of the physical world is gained. All scientific experiments performed on the physical world ultimately become validated by the subjective conscious experience of the experimenters, and the subsequent witnesses to the phenomena and conclusions. — Chris King
