We live in an "information age," surrounded by and immersed in data - words, numbers, images, and voices. It's an age characterized by high speed and high technology, in which every year draws us more tightly into the global network.
But it's not necessarily technology that defines the information age. In his new book, The Information, James Gleick argues that it's the idea of "information" itself that's new - the idea that words, numbers, images, and voices are, despite their differences, all the same sort of stuff. Gleick tells the story of how "the raw material" of the pre-information age - "letters and messages, sounds and images, news and instructions, figures and facts, signals and signs, a hodgepodge of related species" - came to be reimagined as one single, integrated universe of information.
Gleick's account is extraordinary in its sweep: it stretches over three millenia, starting with the invention of writing, describing early forms of communication (the telegraph, the African talking drum), then moving on to the invention of the computer and to the set of networked technologies that shape our lives today. Along the way he introduces famous and not-so-famous thinkers and inventors, from Aristotle to Charles Shannon, who invented information theory at Bell Labs in 1948.
Gleick sees all of these inventions and individuals as part of one big story: the story of the invention of information as a way of thinking about the world and its contents. For Gleick, the essence of information is abstraction. Information exists where one thing (an idea) is abstracted into another thing (a word). But it's also important that information be granular - broken down into what Shannon called "bits." It's this combination of abstraction and regularity that makes the idea of information so useful. The information age arrived, Gleick explains, not with the alphabet, the telephone, or the internet, but when, after it was "made simple, distilled, [and] counted in bits, information was found to be everywhere."
Now there's nothing that can't be understood, ultimately, as a kind of information. Books, statistics, and so on have always seemed like kinds of information - but it's surprising to discover that cells are processors of DNA-based information; that money is a kind of information about "who owns what"; that atoms themselves might be understood as a kind of information, such that physicists can ask, about the universe's "total information capacity" and "memory space," and about the energy cost of "flipping a bit." At the heart of Gleick's book is a sense that this view of the world isn't capricious or arbitrary. The things that exist in the universe really do exist in a layered structure of interrelated abstraction, and that structure is best captured by the idea of information.
Heady ideas? Definitely. But Gleick's story is beautifully told, extensively sourced, and continually surprising, whether or not you find it ultimately convincing.
