The brain’s many organic processes most likely utilize quantum effects as well as classical ones. The classical elements include the physiology, chemistry and electro-dynamics of the brain. The quantum elements may include synaptic connections and large-scale, non-local coherence of brain functioning. The organization and dynamical functioning of these processes in networks and “mappings” – in the context of the shear complexity characteristic of the human brain – produces a tangled hierarchy that emerges as mind. Mind is non-conscious. Much mental processing goes on of which we are unaware. (We can be mindful about things that we remain unaware of at any particular moment.) Some of what mind contains may be/can be offered up to consciousness. The intersection of mind and consciousness produces self.
Socrates said: know thyself. Freud said: where It is, I shall be.
Consciousness itself is primary.
