Consciousness and the Universe: Quantum Physics, Evolution, Brain & Mind

(A) Consciousness is not an independent quality but arose as a natural evolutionary consequence of the biological adaptation of brains and nervous systems. The most popular scientific view is that consciousness emerged as a property of complex biological computation during the course of evolution. Opinions vary as to when, where and how consciousness appeared, e.g. only recently in humans, or earlier in lower organisms. Consciousness as evolutionary adaptation is commonly assumed to be epiphenomenal (i.e. a secondary effect without independent influence), though it is frequently argued to confer beneficial advantages to conscious species.

(B) Consciousness is a quality that has always been in the universe. Spiritual and religious approaches assume consciousness has been in the universe all along, e.g. as the ‘ground of being’, ‘creator’ or component of an omnipresent ‘God’. Panpsychists attribute consciousness to all matter. Idealists contend consciousness is all that exists, the material world an illusion.

(C) Precursors of consciousness have always been in the universe; biology evolved a mechanism to convert conscious precursors to actual consciousness. This is the view implied by Whitehead (1929; 1933) and taken in the Penrose-Hameroff theory of ‘orchestrated objective reduction’ (‘Orch OR’). Precursors of consciousness, presumably with proto-experiential qualities, are proposed to exist as the potential ingredients of actual consciousness, the physical basis of these proto-conscious elements not necessarily being part of our current theories of the laws of the universe.
