A Personal Account of External Cognition: My Life as Someone Else's Wikipedia


I first heard about External Cognition while working on my MA at UBC. I found myself rapidly developing an interest in philosophy of mind and cognitive sciences, especially in modelling the mind (or consciousness). External Cognition seemed like an interesting way of questioning the mind-brain reduction, but ultimately, some of the claims made by supporters of External Cognition also seemed outlandish, too far a stretch of what we consider “thinking” or “knowing.” For the most part, I went on to disregard External Cognition as a serious model, but occasionally, events in my own life became doubts that gnawed at my skepticism.

For review, External Cognition is the view, stated originally in a paper by Clark and Chalmers, that cognition can be located “outside of the head.” For example, I cannot specify in great detail the location of the nearest shopping mall, but I can tell you that if you drive along a particular road in the right direction for long enough, you'll find it. Now, in a classical, perhaps Rylean, understanding, one would not say that I “know” that the mall sits at a certain intersection, but I do know how to get to the mall. The supporter of External Cognition would instead say that I do know the location of the mall, but my knowledge cannot be located in the head; instead, the knowledge can be located on the recommended street and direction. Another example may be helpful. Imagine a logician or mathematician working on an especially problematic proof. Intuitively, one might consider the logician as thinking through the proof, but at the same time, much of that thinking takes place on the scratch paper the logician uses to assist his figuring. Classical, or perhaps na├»ve, understandings would locate the thinking inside the logician's head, but External Cognition advocates would point to the large amount of “thought” located on the page itself. Indeed, one might even reconstruct the logician's reasoning from his notes, so why would one not say that the thinking happens outside of the head? External Cognition supporters frame cognition as a process which spans inside and outside, taking place in the head, but also on the page, the computer screen, etc. Rather than view the logician's notes as mere tools or shortcuts, External Cognition equates the mind with what would otherwise be considered its aids. If this theory seems implausible to you, then you share my initial skepticism. Now, on to how that initial skepticism transformed into tentative speculation.

I have the great fortune to have found a life-partner who shares my intellectual and academic interests (and I hers). Consequently, we have learned a great deal from one another, and we consider intellectual exchange an important pair-bonding activity and cornerstone of our relationship. As much as we consider ourselves intellectual equals, we have also had the opportunity to learn about how our intellectual capacities differ. In particular, I have the better memory, so I often find myself taking the role of prompt, providing my partner the proper names, dates, or terms to fill in the blanks in her conversations. We have engaged in such conversations, by ourselves or with others, for years, but something changed with the rise of Wikipedia.

I adore Wikipedia, and I often find myself idly browsing articles, checking back on facts I thought I knew, expanding my understanding on some topics, and researching incomplete particles of information gleaned from others in casual conversation. Given my memory, in my post-Wikipedia life, I tend to walk around with more ready facts, names, dates, theories, than I did in primitive pre-Wikipedia days. As such, I have become better capable of filling in gaps for my partner, or remembering gaps I cannot complete for later research or fact-checking. My partner shares my adoration for Wikipedia as well, so we often recommend articles to one another and discuss them by ourselves or with our friends. According to our usual pattern, I often find myself throwing in a proper name or technical term where my partner's otherwise impeccable explanation falters. At times, I find myself feeling like a living Wikipedia, always at the ready to supply the answer, and that feeling caused me to return to my initial evaluation of External Cognition.

In many conversations, I function as my partner's external memory. She knows the substance of what she wants to say, but she uses me for the occasional prompt. As a unit, we function quite effortlessly, able to hold conversations on a wide variety of topics. The unit simply distributes its functions in a very particular way; namely, spontaneous recall weighs heavily on my side. Nevertheless, the explanation, the substance of the conversation may originate from either of us (I do often hold my tongue to some extent; I've long ago learned how our unit distributes social graces, and those weigh heavily on her side).

Now, imagine my partner goes out on her own, but brings along a bluetooth headset so that I can hear her conversations, but only she can hear me. Further imagine that she has a very small, inconspicuous headset, one not readily noticeable by her interlocutors. To an outside observer, she would seem to be carrying on conversations effortlessly, with perhaps small pauses to recall some particular. To the outsider, she would simply seem to have an extensive memory. These kinds of thought experiments lend a certain plausibility to External Cognition. My partner uses my memory like she would scratch paper when solving a math problem. My memory is her tool, and she uses it effectively, so why not say that she has an efficient external memory?

“Smart” phones only push the comparison further by placing even more information at one's disposal.

Justifications for Intellectual Property Part 1: Utilitarianism

There is no way this tutorial series would be complete without some discussion of justifications for intellectual property. While not necessarily a matter of law, some knowledge of the philosophical foundations will provide a better sense of the values at stake in intellectual property debates. Notice, for instance, that the tutorials on fair use were punctuated with appeals to values, social goods, and individual rights. Without an understanding of the moral and political framework against which the law stands, one can very easily find oneself in a stalemate, with one value pitted against another and no way of deciding which should prevail. To understand the jurisprudence around intellectual property rights, one has to have some idea of the justifying theories to which attorneys and judges appeal in their arguments and decisions. So, without further ado, let's get to the tutorial.
There are three main ways of justifying intellectual property rights: the Utilitarian theory, the Lab…

Digital Distribution

Continuing on this week's topic of first sale and digital distribution, I thought I would discuss emerging distribution strategies for digital media. The outline below comes from my observations on new media technologies, some of which can be found in an earlier entry here. As far as I can tell, digital distribution strategies can be divided into three categories according to salient features.
Access-Based distribution (“cloud” based services) the customer subscribes to a service the subscription entitles the customer to access content stored on the provider's servers content is remotely stored, though some items may be remotely cached for offline use when the subscription is terminated, the customer loses access to all content the content provider can exercise a great deal of control over what content is offered; the selection of content may vary over time, meaning that the customer is only guaranteed access to the cloud, not any particular item in the cloud typifie…

Justifications for Intellectual Property Part 2: Labor-Desert Theories

I know it's been a little while, but I want to finish this tutorial series rather than abandoning it and moving on to other topics. Of course, I would have liked to have finished it by now, but various research and teaching-related obstacles have kept me nose down in the Real rather than preparing content to be released into the internet. Nevertheless, I'm returning to routine, so I'm going to release this installment today, rather than wait for my usual MWF release schedule.
At any rate, let's pick up where we left off and talk about justifications for intellectual property rights. While the utilitarian justification discussed in the last post enjoys the status of having been enshrined in law, scholars and jurists have often brought in other property-justifying theories. Perhaps the most popular of these are Labor-Desert justifications, best exemplified by John Locke (the philosopher, not the character on Lost).
In his Second Treatise on Civil Government, Locke const…
