Before brains there was no color or sound in the universe, nor was there any flavor or aroma and probably little sense and no feeling or emotion.

What it comes down to is that modern society discriminates against the right hemisphere.

To see a promising solution to a dilemma and then just leave it to questionable development at its own pace without trying to aid its implementation would seem a dereliction.

Sperry's thinking about subjective experience, consciousness, the mind, and human values makes a powerful plea for a new scientific examination of ethics in the workings of consciousness. These ideas were crystallized in his paper The Impact and Promise of the Cognitive Revolution (1993).

What is needed to break the vicious spiral is a world-wide change in attitudes, values, and social policy. As Einstein put it, We need a substantially new manner of thinking if mankind is to survive.

When the brain is whole, the unified consciousness of the left and right hemispheres adds up to more than the individual properties of the separate hemispheres.

There probably is no more important quest in all science than the attempt to understand those very particular events in evolution by which brains worked out that special trick that has enabled them to add to the cosmic scheme of things: color, sound, pain, pleasure, and all the other facets of mental experience.

The grand design of nature perceived broadly in four dimensions, including the forces that move the universe and created man, with special focus on evolution in our own biosphere, is something intrinsically good that it is right to preserve and enhance, and wrong to destroy and degrade.

The cells and fibers of the brain must carry some kind of individual identification tags, presumably cytochemical in nature, by which they are distinguished one from another almost, in many regions, to the level of the single neurons.
