This triumph of the “networked” and the “hyperlinked” unsettles everything: facts (those who think that Barack Obama was born in Kenya also have facts), books (they are unable to contain “linked” and infinite knowledge) and even knowledge itself (it’s too obsessed with theories and consensus-seeking). Thus, “knowledge has become a network with the characteristics — for better and for worse — of the Net.” This is an ambitious thesis. It’s also not original. “The Postmodern Condition: A Report on Knowledge,” a famous 1979 book by the French philosopher Jean-François Lyotard, makes a similar claim about computerization. “Along with the hegemony of computers comes a certain logic, and therefore a certain set of prescriptions determining which statements are accepted as ‘knowledge statements,’” wrote Lyotard. Weinberger doesn’t mention Lyotard by name but claims that “the Internet showed us that the postmodernists were right.”
