George Armitage Miller lived in a world of words. Every object that fell into his vision and every word he heard instantly set off a cascade of associations, synonyms, and antonyms that flashed through his mind. A psychologist with an interest in understanding the cognitive processes behind language and information processing, he founded the Center for Cognitive Studies at Harvard. And, in 1980, long before digital networks were part of everyday life, he was the driving force behind the development of Wordnet, a still functioning online database that details the myriad lexical relationships between most words in the English language.
But for a while in 1983 he was stuck looking for a word to describe the relationship between living organisms and information. A fan of Erwin Schrödinger’s What Is Life, Miller was certain that Schrödinger had left something important out of his definition of life. In order for living organisms to consume free energy per entropy’s demands, Miller insisted, they had to be able to find it, and to find it they had to have the ability to acquire, interpret, and then respond to useful information about the world around them. It meant, in other words, that a significant proportion of the energy they captured was expended seeking out information using their senses and then processing it in order to find and capture more energy.
