Roger Sperry Quotes

The new way of thinking, spawned by the cognitive revolution, shows strong promise ... Reversing previous doctrine in science, the new paradigm affirms that the world we live in is driven not solely by mindless physical forces but, more crucially, by subjective human values. Human values become the underlying key to world change.

The upward thrust of evolution as part of the design becomes something to preserve and revere.

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.

It seems important that the social value factor be more generally recognized as a powerful causal agent in its own right and something to be dealt with directly as such. No more critical task can be projected for the 1970s than that of seeking for civilized society a new, elevated set of value guidelines more suited to man's expanded numbers and new powers over nature, a frame of reference for value priorities that will act to secure and conserve our world instead of destroying it.

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.

The centermost processes of the brain with which consciousness is presumably associated are simply not understood. They are so far beyond our comprehension that no one I know of has been able to imagine their nature.

The time has passed when nations should be allowed to do as they individually wish with regard to global matters, each striving solely in its own interests, with the more powerful now able to destroy all humanity and more. For the common good, we need to frame and abide by a higher system of law and justice, designed with less national, more godlike, perspectives for the preservation and welfare of the biosphere as a whole.
The problems of setting up and administering an effective, international force of this kind can hardly be more grave, formidable or insoluble than those we encounter on any alternative course.

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.

It is mutual fear and distrust that mostly generate world tensions and these can be traced in no small measure, like other root causes of worsening world conditions, to different people's conflicting and often intolerant, value-belief differences ... Whereas in the past science did little, if anything, to remedy this situation and in some ways made things worse, our reformed "macro-determinist" science that includes consciousness and subjective values ... provides common universal ethical foundations on which all nations could work to build a World Government or at least a World Security System to help control nuclear developments and other global threats that require international collaboration.

Any model or description that leaves out conscious forces ... is bound to be sadly incomplete and unsatisfactory ... This scheme is one that puts mind back over matter, in a sense, not under or outside or beside it. It is a scheme that idealizes ideas and ideals over physical and chemical interactions, nerve impulse traffic, and DNA. It is a brain model in which conscious mental psychic forces are recognized to be the crowning achievement of some five hundred million years or more of evolution.

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.

Prior to the advent of brain, there was no color and no sound in the universe, nor was there any flavor or aroma and probably rather little sense and no feeling or emotion. Before brains the universe was also free of pain and anxiety.

I have never been entirely satisfied with the materialistic or behavioristic thesis that a complete explanation of brain function is possible in purely objective terms with no reference whatever to subjective experience; i.e., that in scientific analysis we can confidently and advantageously disregard the subjective properties of the brain process. I do not mean we should abandon the objective approach or repeat the errors of the earlier introspective era. It is just that I find it difficult to believe that the sensations and other subjective experiences per se serve no function, have no operational value and no place in our working models of the brain.

The objective psychologist, hoping to get at the physiological side of behavior, is apt to plunge immediately into neurology trying to correlate brain activity with modes of experience ... The result in many cases only accentuates the gap between the total experience as studied by the psychologist and neural activity as analyzed by the neurologist.
