About Rationally Speaking
Rationally Speaking is a blog maintained by Prof. Massimo Pigliucci, a philosopher at the City University of New York. The blog reflects the Enlightenment figure Marquis de Condorcet's idea of what a public intellectual (yes, we know, that's such a bad word) ought to be: someone who devotes himself to "the tracking down of prejudices in the hiding places where priests, the schools, the government, and all long-established institutions had gathered and protected them."

Book Review: Too Big to Know
How do you know what you think you know? What counts as knowledge and what doesn’t? These questions speak to a great semantics-based problem, i.e., trying to define what ‘knowledge’ is. Studying the nature of knowledge falls within the domain of a branch of philosophy called epistemology, which happens largely to be the subject matter of David Weinberger’s book Too Big Too Know.
According to Weinberger, most of us tend to think that there are certain individuals — called experts — who are knowledgeable about a certain topic and actually possess knowledge of it. Their knowledge and expertise is thought to be derived from their ability to correctly interpret facts, often through some theoretical lens. Today, like facts, experts too have become ubiquitous. It seems we are actually drowning in a world with too many experts and too many facts, or at least an inability to pick out the true experts and the important facts.
Most of us are appalled, for instance, when we hear the facts about how many people are living in poverty in the United States. However, these facts can be misleading and most people don’t have enough time to think critically about the facts that are hurled at them every day. There might in fact be “X” amount of people living in poverty in the United States, but did you know that someone with a net-worth north of one million dollars can technically be living in poverty? How the government defines poverty is very different than the connotation that many of us have of that word. The amount of income you have is the sole factor used to determine if one is “living in poverty,” but this bit of information seldom accompanies the facts about how many people are “living in poverty.”
I recently posed a question on Facebook asking my subscribers if a fact could be false. To my surprise, there was much disagreement over this seemingly simple question. Weinberger reminds us that facts were once thought to be the antidote to disagreement, but it seems that the more facts are available to us, the more disagreements we seem to have, even if they are meta-factual.
It’s unquestionable that today’s digitally literate class of people have more facts at their fingertips than they know what to do with. Is this, however, leading us any closer to Truth? Well, not necessarily. This is because not all facts are created equal, and not all facts are necessarily true. Facts are statements about objective reality that we believe are true. However, while a fact can be false, truth is such regardless of our interpretation of it — we can know facts, but we can’t necessarily know Truth.
In the book, Weinberger draws an important distinction between classic facts and networked facts. The late U.S. Senator Daniel Patrick Moynihan famously said: “Everyone is entitled to his own opinions, but not to his own facts.” What he meant by that was that facts (what Weinberger calls classic facts) were thought to give us a way of settling our disagreements. Networked facts, however, open up into a network of disagreement depending on the context in which they are interpreted. “We have more facts than ever before,” writes Weinberger, “so we can see more convincingly than ever before that facts are not doing the job we hired them for.” This seems to be true even amongst people who use a similar framework and methodology for arriving at their beliefs (e.g., scientists).
One of Weinberger’s central arguments is that the Digital Revolution has allowed us to create a new understanding of what knowledge is and where it resides. Essentially, he claims that the age of experts is over, the facts are no longer the facts (in the classical sense), and knowledge actually resides in our networks. While this is an interesting idea, I’m not sure it’s entirely true.
Knowledge is a strange thing since it depends on the human mind in order to exist. I have a stack of books sitting on my desk, but I don’t point to them and say there is a stack of knowledge sitting on my desk. I simply don’t yet know if there is any knowledge to be gleaned from those books. For this reason, I don’t think knowledge can exist on networks either. Knowledge requires human cognition in order to exist, which means that it only exists in experience, thus giving it this strange ephemeral characteristic. I cannot unload my knowledge and store it anywhere, then retrieve it at a later date. It simply ceases to exist outside of my ability to cognize it.
Knowledge, Weinberger argues, exists in the networks we create, free of cultural and theoretical interpretations. It seems that he is expanding on an idea from Marshall McLuhan, who famously said, “The medium is the message.” Is it possible, then, that knowledge is the medium? The way I interpret his argument, Weinberger seems to be claiming that the medium also shapes what counts as knowledge. Or, as he himself puts it, “transform the medium by which we develop, preserve, and communicate knowledge, and we transform knowledge.” This definition of knowledge is, however, problematic if one agrees that knowledge can only exist in the mind of a human (or comparable) being. To imply that a unified body of knowledge exists “out there” in some objective way and that human cognition isn’t necessary for it to exist undermines any value the term has historically had. Ultimately, I don’t agree with Weinberger’s McLuhanesque interpretation that knowledge has this protean characteristic.
In a recent essay in The Atlantic Nicholas Carr posed the question: “Is Google Making Us Stupid?” His inquiry spawned a fury of questions pertaining to our intelligence and the Net. Although Weinberger has high hopes for what the Net can do for us, he isn’t necessarily overly optimistic either. In fact, he claims that it’s “incontestable that this is a great time to be stupid” too. The debate over whether the Internet makes us smarter or dumber seems silly to me, though. I cannot help but conclude that it makes some people smarter and some people dumber — it all depends on how it is used. Most of us (myself included) naturally like to conjugate in our digital echo chambers and rant about things we think we know (I suspect this is why my provocative “Who Wants to Maintain Clocks?” essay stirred up some controversy — most RS readers don’t usually hear these things in their echo chambers).
Weinberger also argues that having too much information isn’t a problem, but actually a good thing. Again, I disagree. In support of this claim, he piggybacks off of Clay Shirky, who tells us that the ills of information overload are simply filtering problems. I, however, don’t see filtering as a panacea because filtering still requires the valuable commodity of time. At some point, we have to spend more time filtering than we do learning. An aphorism by Nassim Taleb comes to mind: “To bankrupt a fool, give him information.”
Overall, Weinberger does a nice job of discussing the nature of knowledge in the Digital Age, even though I disagree with one of his main points that knowledge exists in a new networked milieu. The book is excellent in the sense that it encourages us to think deeply about the messy nature of epistemology — yes, that’s an opinion and not a fact!
