The Rational Optimist_ How Prosperity Evolves - Matt Ridley [17]
You employ no tailor, but you can browse the internet and instantly order from an almost infinite range of excellent, affordable clothes of cotton, silk, linen, wool and nylon made up for you in factories all over Asia. You have no carriage, but you can buy a ticket which will summon the services of a skilled pilot of a budget airline to fly you to one of hundreds of destinations that Louis never dreamed of seeing. You have no woodcutters to bring you logs for the fire, but the operators of gas rigs in Russia are clamouring to bring you clean central heating. You have no wick-trimming footman, but your light switch gives you the instant and brilliant produce of hardworking people at a grid of distant nuclear power stations. You have no runner to send messages, but even now a repairman is climbing a mobile-phone mast somewhere in the world to make sure it is working properly just in case you need to call that cell.

That is the magic that exchange and specialisation have wrought for the human species. ‘In civilized society,’ wrote Adam Smith, an individual ‘stands at all times in need of the co-operation and assistance of great multitudes, while his whole life is scarce sufficient to gain the friendship of a few persons.’ In Leonard Read’s classic 1958 essay ‘I, Pencil’, an ordinary pencil describes how it came to be made by millions of people, from loggers in Oregon and graphite miners in Sri Lanka to coffee bean growers in Brazil (who supplied the coffee drunk by the loggers). ‘There isn’t a single person in all these millions,’ the pencil concludes, ‘including the president of the pencil company, who contributes more than a tiny, infinitesimal bit of know-how.’ The pencil stands amazed at ‘the absence of a master mind, of anyone dictating or forcibly directing these countless actions which bring me into being.’
This is what I mean by the collective brain. As Friedrich Hayek first clearly saw, knowledge ‘never exists in concentrated or integrated form but solely as the dispersed bits of incomplete and frequently contradictory knowledge which all the separate individuals
