For the purposes of science, information had to mean something special. Three centuries earlier, the new discipline of physics could not proceed until appropriated words that were ancient and vague-force, mass, motion, and even time-and gave them new meanings. Newton made these terms into quantities, suitable for use in mathematical formulas. Until then, motion {for example} had been just as soft and inclusive a term as information. For Aristotelians, motion covered a far-flung family of phenomena: a peach ripening, a stone falling, a child growing, a body decaying. That was too rich. Most varieties of motion had to be tossed out before Newton's laws could apply and the Scientific Revolution could succeed. In the nineteenth century, energy began to undergo a similar transformation: natural philosophers adapted a word meaning vigor or intensity. They mathematicized it, giving energy its fundamental place in the physicists' view of nature.It was the same with information. A rite of purification became necessary.And then, when it was made simple, distilled, counted in bits, information was found to be everywhere. book-quoteinformationscientific-revolutionjargonWe all behave like Maxwell's demon. Organisms organize. In everyday experience lies the reason sober physicists across two centuries kept this cartoon fantasy alive. We sort the mail, build sand castles, solve jigsaw puzzles, separate wheat from chaff, rearrange chess pieces, collect stamps, alphabetize books, create symmetry, compose sonnets and sonatas, and put our rooms in order, and all this we do requires no great energy, as long as we can apply intelligence. We propagate structure {not just we humans but we who are alive}. We disturb the tendency toward equilibrium. It would be absurd to attempt a thermodynamic accounting for such processes, but it is not absurd to say we are reducing entropy, piece by piece. Bit by bit. The original demon, discerning one molecules at a time, distinguishing fast from slow, and operating his little gateway, is sometimes described as "superintelligent," but compared to a real organism it is an idiot savant. Not only do living things lessen the disorder in their environments; they are in themselves, their skeletons and their flesh, vesicles and membranes, shells and carapaces, leaves and blossoms, circulatory systems and metabolic pathways - miracles of pattern and structure. It sometimes seems as if curbing entropy is our quixotic purpose in the universe. book-quoteinformationentropymaxwellInformation, defined intuitively and informally, might be something like 'uncertainty's antidote.' This turns out also to be the formal definition- the amount of information comes from the amount by which something reduces uncertainty...The higher the {information} entropy, the more information there is. It turns out to be a value capable of measuring a startling array of things- from the flip of a coin to a telephone call, to a Joyce novel, to a first date, to last words, to a Turing test...Entropy suggests that we gain the most insight on a question when we take it to the friend, colleague, or mentor of whose reaction and response we're least certain. And it suggests, perhaps, reversing the equation, that if we want to gain the most insight into a person, we should ask the question of qhose answer we're least certain... Pleasantries are low entropy, biased so far that they stop being an earnest inquiry and become ritual. Ritual has its virtues, of course, and I don't quibble with them in the slightest. But if we really want to start fathoming someone, we need to get them speaking in sentences we can't finish. book-quoteinformationFor Socrates, all virtues were forms of knowledge. To train someone to manage an account for Goldman Sachs is to educate him or her in a skill. To train them to debate stoic, existential, theological, and humanist ways of grappling with reality is to educate them in values and morals. A culture that does not grasp the vital interplay between morality and power, which mistakes management techniques for wisdom, which fails to understand that the measure of a civilization is its compassion, not its speed or ability to consume, condemns itself to death. Morality is the product of a civilization, but the elites know little of these traditions. They are products of a moral void. They lack clarity about themselves and their culture. They can fathom only their own personal troubles. They do not see their own bases or the causes of their own frustrations. They are blind to the gaping inadequacies in our economic, social, and political structure and do not grasp that these structures, which they have been taught to serve, must be radically modified or even abolished to stave off disaster. They have been rendered mute and ineffectual. "What we cannot speak about" Ludwig Wittgenstein warned "we must pass over in silence. book-quoteteachinginformationintellectual
