The relation between psyche and soma, mind and brain, are peculiarly intimate; but, as in marriage, the partners are not inseparable: indeed their divorce was one of the conditions for the mind's independent history and its cumulative achievements.
But the human mind possesses a special advantage over the brain: for once it has created impressive symbols and has stored significant memories, it can transfer its characteristic activities to materials like to stone and paper that outlast the original brain's brief life-span. When the organism dies, the brain dies, too, with all its lifetime accumulations. But the mind reproduces itself by transmitting its symbols to other intermediaries, human and mechanical, than the particular brain that first assembled them.

The difference between mind and brain is that brain deals only with memorized, subjective, special-case experiences and objective experiments, while mind extracts and employs the generalized principles and integrates and interrelates their effective employment. Brain deals exclusively with the physical, and mind exclusively with the metaphysical.
Buckminster Fuller
I have a very one-track mind that needs to concentrate. I asked myself which issue is more important: whether mental states are more left- or right-hemispheric, or whether they are causal in brain function. From weighing the pros and cons, I decided that the left-brain, right-brain work was well in orbit and that it would be more important to shift my primary focus to consciousness.
The mind-brain issues are intrinsically more compelling. They carry strong humanistic as well as scientific implications. I could foresee changes in our world view, guiding beliefs, and social values. In the context of today's worsening world conditions and our imperiled future, this work seemed far more important than whether you can find a brain theory enabling people to learn faster, draw better, make better medical diagnoses, and so on.
We're beginning to learn the hard way that today's global ills are not cured by more and more science and technology.Roger Wolcott Sperry
One of the more important things to come out of the split-brain work, as an indirect spin-off, is a revised concept of the nature of consciousness and its fundamental relation to brain processing. The key development here is a switch from prior non-causal, parallelist views to a new causal, or "interactionist" interpretation that ascribes to inner experience an integral causal control role in brain function and behavior. In effect, and without resorting to dualist views, the mental forces and properties of the conscious mind are restored to the brain of objective science from which they had long been excluded on materialist-behaviorist principles.
Roger Wolcott Sperry
Odd that the brain could function on its own, without acquainting him with its purposes, its reasons. But the brain was an organ, like the spleen, heart, kidneys. And they went about their private activities. So why not the brain?
Philip Kindred - a.k.a. PKD Dick
My suggestion is that at each state the proper order of operation of the mind requires an overall grasp of what is generally known, not only in formal logical, mathematical terms, but also intuitively, in images, feelings, poetic usage of language, etc. (Perhaps we could say that this is what is involved in harmony between the 'left brain' and the 'right brain'). This kind of overall way of thinking is not only a fertile source of new theoretical ideas: it is needed for the human mind to function in a generally harmonious way, which could in turn help to make possible an orderly and stable society.
