Function Quotes

“Man cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. Animals obtain food by force. man had no claws, no fangs, no horns, no great strength of muscle. He must plant his food or hunt it. To plant, he needs a process of thought. To hunt, he needs weapons,and to make weapons - a process of thought. From this simplest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and we have comes from a single attribute of man -the function of his reasoning mind.”

“Funny thing, your brain, how it always functions on one level or another. How, even stuck in some sort of subconcious limbo, it works your lungs, your muscle twitches, your heart, in fact, in symphony with your heart, allowing it to feel love. Pain. Jealousy. Guilt. I wonder if it’s the same for people, lost in comas. Is there really such a thing”

“There was a sergeant at a desk. I knew he was a sergeant because I recognized the marks on his uniform, and I knew it was a desk because it's always a desk. There's always someone at a desk, except when it's a table that functions as a desk. You sit behind a desk, and everyone knows you're supposed to be there, and that you're doing something that involves your brain. It's an odd, special kind of importance. I think everyone should get a desk; you can sit behind it when you feel like you don't matter.”

“The brain is more than an assemblage of autonomous modules, each crucial for a specific mental function. Every one of these functionally specialized areas must interact with dozens or hundreds of others, their total integration creating something like a vastly complicated orchestra with thousands of instruments, an orchestra that conducts itself, with an ever-changing score and repertoire.”

“Courage is about learning how to function despite the fear, to put aside your instincts to run or give in completely to the anger born from fear. Courage is about using your brain and your heart when every cell of your body is screaming at your to fight or flee - and then following through on what you believe is the right thing to do.”

“Once upon a time ... the only autonomous intelligences we humans knew of were us humans. We thought then that if humankind ever devised another intelligence that it would be the result of a huge project ... a great mass of silicon and ancient transistors and chips and circuit boards ... a machine with lots of networking circuits, in other words, aping-if you will pardon the expression-the human brain in form and function. Of course, AIs did not evolve that way. They sort of slipped into existence when we humans were looking the other way.”

“The word courage comes from the same stem as the French word Coeur, meaning "heart." Thus just as one's heart, by pumping blood to one's arms, legs, and brain enables all the other physical organs to function, so courage makes possible all the psychological virtues. Without courage other values wither away into mere facsimiles of virtue.”

“The brain is a tissue. It is a complicated, intricately woven tissue, like nothing else we know of in the universe, but it is composed of cells, as any tissue is. They are, to be sure, highly specialized cells, but they function according to the laws that govern any other cells. Their electrical and chemical signals can be detected, recorded and interpreted and their chemicals can be identified; the connections that constitute the brain's woven feltwork can be mapped. In short, the brain can be studied, just as the kidney can.”

“My plea to educators and parents is that they should give some thought to the nature of the brain of a child, for the brain is a living mechanism, not a machine. In case of breakdown, it can substitute one of its parts for the function of another. But it has its limitations. It is subject to inexorable change with the passage of time.”

“The brain is not, like the liver, heart and other internal organs, capable from the moment of birth of all the functions which it ever discharges; for while in common with them, it has certain duties for the exercise of which it is especially intended, its high character in man, as the organ of conscious life, the supreme instrument of his relations with the rest of nature, is developed only by a long and patient training.”

“An immune system of enormous complexity is present in all vertebrate animals. When we place a population of lymphocytes from such an animal in appropriate tissue culture fluid, and when we add an antigen, the lymphocytes will produce specific antibody molecules, in the absense of any nerve cells. I find it astonishing that the immune system embodies a degree of complexity which suggests some more or less superficial though striking analogies with human language, and that this cognitive system has evolved and functions without assistance of the brain.”

“I consider the differences between man and animals in propensities, feelings, and intellectual faculties, to be the result of the same cause as that which we assign for the variations in other functions, viz. difference of organization; and that the superiority of man in rational endowments is not greater than the more exquisite, complicated, and perfectly developed structure of his brain, and particularly of his ample cerebral hemispheres, to which the rest of the animal kingdom offers no parallel, nor even any near approximation, is sufficient to account for.”

“The fate of the physiology of the brain is independent of the truth and falsity of my assertions relative to the laws of the organization of the nervous system, in general, and of the brain in particular, just as the knowledge of the functions of a sense is independent of the knowledge of the structure of its apparatus.”

“Whoever would not remain in complete ignorance of the resources which cause him to act; whoever would seize, at a single philosophical glance, the nature of man and animals, and their relations to external objects; whoever would establish, on the intellectual and moral functions, a solid doctrine of mental diseases, of the general and governing influence of the brain in the states of health and disease, should know, that it is indispensable, that the study of the organization of the brain should march side by side with that of its functions.”
