Das Wissen der Menschheit verdoppelt sich dank des Internets inzwischen alle fünf bis zehn Jahre. Wir stehen Tag für Tag vor einer unglaublichen Menge neuer Informationen. Kein lebendes Wesen kann diese Wissensflut noch beherrschen. Früher navigierten herausragende Experten sicher durch die Welt des Wissens heute stehen wir alle in einem undurchschaubaren Dschungel an miteinander vernetzten Informationen, deren Wert wir oft nicht einschätzen können. Die Krise des Wissens erschüttert unsere wichtigsten Institutionen, von denen wir meinten, sie seien so unerschütterlich wie ihre Marmor- und Betonfassaden: Universitäten diskutieren, ob Wissenschaftler ihre Forschungsergebnisse frei zugänglich im Internet veröffentlichen sollten und nicht wie bisher in renommierten, aber teuren Fachzeitschriften. Bibliothekare diskutieren darüber, inwieweit neben dem Wissen von Wissenschaftlern auch das der Masse Eingang in die Bibliothek finden kann. Unternehmensberatungen experimentieren mit Expertennetzwerken, die ihre Kunden mit einer Vielzahl von Standpunkten und Optionen konfrontieren. Und Unternehmen experimentieren mit dezentralisierten Entscheidungsprozessen, die das in ihren Netzwerken verstreute Wissen nutzen.
Fest steht: Unser bisheriges Konzept von Wissen ist seit der Erfindung des Internets nutzlos geworden. Pointiert und scharfsinnig entwirft David Weinberg, wie ein neues tragfähiges Konzept des Wissens aussieht. Er macht zudem klar, wie sich unser Umgang mit dem Wissen ändern muss, damit wir auch in Zukunft genau jene Fakten finden, die uns wirkliche Erkenntnis bringen können.

In this title, a leading philosopher of the internet explains how knowledge and expertise can still work - and even grow stronger - in an age when the internet has made topics simply Too Big to Know. Knowing used to be so straightforward. If we wanted to know something we looked it up, asked an expert, gathered the facts, weighted the possibilities, and honed in on the best answer ourselves. But, ironically, with the advent of the internet and the limitless information it contains, we're less sure about what we know, who knows what, or even what it means to know at all. Knowledge, it would appear, is in crisis. And yet, while its very foundations seem to be collapsing, human knowledge has grown in previously unimaginable ways, and in inconceivable directions, in the Internet age. We fact-check the news media more closely and publicly than ever before. Science is advancing at an unheard of pace thanks to new collaborative techniques and new ways to find patterns in vast amounts of data. Businesses are finding expertise in every corner of their organization, and across the broad swath of their stakeholders. We are in a crisis of knowledge at the same time that we are in an epochal exaltation of knowledge. In "Too Big to Know", Internet philosopher David Weinberger explains that, rather than a systemic collapse, the Internet era represents a fundamental change in the methods we have for understanding the world around us. Weinberger argues that our notions of expertise - what it is, how it works, and how it is cultivated - are out of date, rooted in our pre-networked culture and assumptions. For thousands of years, we've relied upon a reductionist process of filtering, winnowing, and otherwise reducing the complex world to something more manageable in order to understand it. Back then, an expert was someone who had mastered a particular, well-defined domain. Now, we live in an age when topics are blown apart and stitched together by momentary interests, diverse points of view, and connections ranging from the insightful to the perverse. Weinberger shows that, while the limits of our own paper-based tools have historically prevented us from achieving our full capacity of knowledge, we can now be as smart as our new medium allows - but we will be smart differently. For the new medium is a network, and that network changes our oldest, most basic strategy of knowing. Rather than knowing-by-reducing, we are now knowing-by-including. Indeed, knowledge now is best thought of not as the content of books or even of minds, but as the way the network works. Knowledge will never be the same - not for science, not for business, not for education, not for government, not for any of us. As Weinberger makes clear, to make sense of this new system of knowledge, we need - and smart companies are developing - networks that are themselves experts. Full of rich and sometimes surprising examples from history, politics, business, philosophy, and science, "Too Big to Know" describes how the very foundations of knowledge have been overturned, and what this revolution means for our future.
