We feel like more than just the sum of a trillion neurons. We feel like more than just three pounds of wet flesh, and so simply describing the brain in terms of its neurotransmitters and neurons and all these chemicals and exciting ingredients doesn't fully grapple with what it feels like to be human, the first person subjective experience of being a conscious being. When you think about the really grand epic questions of neuroscience ... what is consciousness? How can we form a scientific explanation for consciousness, for human experience? That is the holy grail.
Jonah Lehrer
In an extreme view, the world can be seen as only connections, nothing else. We think of a dictionary as the repository of meaning, but it defines words only in terms of other words. I liked the idea that a piece of information is really defined only by what it's related to, and how it's related. There really is little else to meaning. The structure is everything. There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.
Tim Berners-Lee
Since the universe must contain millions of appropriate planets, consciousness in some form - but not with the paired eyes and limbs, and the brain built of neurons in the only example we know - may evolve frequently. But if only one origin of life in a million ever leads to consciousness, then Martian bacteria most emphatically do not imply Little Green Men.)
Stephen Jay Gould
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).
Roger Wolcott Sperry
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.
Roger Wolcott Sperry
Proceeding from ourselves, from our own human consciousness, the only consciousness which we feel from within and in which feeling is identical with being, we attribute some sort of consciousness, more or less dim, to all living things, and even to the stones themselves, for they also live. And the evolution of organic beings is simply the struggle to realize fullness of consciousness through suffering, a continual aspiration to be others without ceasing to be themselves, to break and yet to preserve their proper limits.
