894 Reading Notes: Foucault

How Foucault is productive for me

"Discourse is.. a space of exteriority in which a network of distinct sites is deployed" (p. 55)

When I first studied Foucault in Modern Rhetoric, I approached his ideas with a certain level of discomfort, mostly because I wasn’t sure that I bought into his ideas about how power constructs subjects.  However, his insights in The Archeology of Knowledge have been more compelling as well as more productive for my purposes, and I tend to rank him higher as a theorist as a result.  Foucault’s view of “discourse” as a theoretical construct is something that I believe can be productively employed in the more theoretical social sciences, in cultural studies, and very definitely in rhetoric. While it’s true that Foucault does not offer a direct methodology for me to explore disciplinarity—particularly since Foucault makes the explicit point that discursive formulations are not equivalent to disciplines but more akin to discursive webs that cross disciplinary boundaries and institutional practices.  However, even if disciplines are not discourses per se, they do employ discourse in the Foucauldian sense and are “disciplined” by such discursive phenomena as Foucault discusses.  The Archeology of Knowledge is not an argument about the social construction of knowledge (see, for example, Berger and Luckmann’s The Social Construction of Reality (1967))  or a version of the rhetoric of science, but rather the discursive construction of knowledge. That discourse is socially constructed is a fairly necessary foundation, of course, but it is not the focus of Foucault’s treatise.  Instead, he is concerned with how epistemologically structured discourses (that is, discursive formulations) emerge with a set of rules (enunciative functions) that in turn shape what can be said and known, and thus create knowledge.   I think some of Foucault’s ideas can definitely be productive for me as I look at disciplines as a community of practice and consider how discourses in the Foucauldian sense are superimposed on disciplines as well as working within disciplines.  I think I can use some of his concepts methodologically in a narrower way, as well.  In other words, even though Foucault is interested in discourses (big D discourse) that go beyond a single discipline or institution, it seems like it would be productive to look for discursive formations and enunciative functions within the discourse (small D) of disciplines and subdisciplines in the academy.

Reading Foucault

What reading Foucault requires (my photo)

My experience reading Foucault was challenging, but educational in several ways.  It goes without saying that I gained a great deal of insight about Foucault’s ideas from the inside.  It’s one thing to read about a theory; it is always a different experience to read the theorist.  However, I also learned some things about how to read a more challenging text.  For example, I eased my way into the book with some preliminary scribbled notes.  As I look back at them now, they hardly seem necessary but they were helpful for dipping my toes into the argument, for example, I started with “History seen as periods with trajectory, continuations…History in other disciplines—like literary studies as disruptions and ruptures.”  I began to think of Thomas Kuhn’s paradigm shifts.  Foucault mentions the “Other” (caps, italicized) (p. 12) I asked, “What does F. mean? How does he use this term (i.e. compared with others who popularized it?”  (After reading the rest of the book, I’m not sure he did do much with it. I’m not saying that Foucault does not discussthe idea that there is an Other that is not being spoken because certainly the idea is salient to him, but I felt it was an indirect point in this book.) After I got going in the book, I thought about the concept of rhizomes from Deleuze and Guatarri (2004). 
Somewhere in part two I started taking more systematic notes, discovering that the outline of the book is, in fact, well-organized.  The table of contents and the chapter titles are a decent roadmap to the theoretical framework.  I also discovered something important about how to read Foucault.  I discovered that is better to read through to the end of a chapter without stopping too much, trying to keep track of the general flow of the discussion but don’t worry about understanding too much until I get a sense of where he is going with something. He often summarizes and rephrases a key point at the end of the chapter, and at the ends of sections, he often recapitulates his arguments.  A great example of this is the end of chapter 4 of part 3 (p. 116).  Even though Foucault did often come back to his main points at the end of chapters, I often had to re-read a chapter.  Rereading a chapter was always more productive than rereading a paragraph multiple times.  In fact, I feel like I understand Foucault overall much better now that I have a sense of the book as a whole that I did at any time or point during the actual reading process. This is the case even as I forget the details.  I don’t know if this has to do with the way Foucault writes per se, or if it is something of a French style.  I feel like Derrida, Deleuze and Guatarri, and Barthes gave me a similar feeling of discursive abundance, of flowing quite a distance before being circling back to make the point.  I might also mention that I discovered that Foucault often provides a road map ahead.  This is also helpful, more than anything when I flip back to these sections after I have read them. 
Occasionally Foucault discusses examples from his earlier studies, Madness and Civilization, Birth of a Clinic, and The Order of Things.   These sections were among the most accessible even though I had not read the works that he referred to.   I don’t think examples are strictly necessary; I wouldn’t argue that he should necessarily have illustrated all of us ideas with examples.  However, when he did have them, I found them helpful.
To wrap up this section, I think I am pleased with how accessible Foucault proved in the end.  If I read more of Foucault’s works, I think I have a better idea how to proceed.

A few quotes I like:

“A statement always has borders peopled by other statements” (p. 97).  
“Archeology is not in search of inventions; and it remains unmoved at the moment (a very moving one, I admit) when for the first time someone was sure of some truth; it does not try to restore the light of those joyful mornings” (p. 144).

Uptake of Foucauldian Discourse Analysis

Some time back I became interested in learning more about discourse analysis. When I started looking for books and materials, I learned that “discourse analysis” means many different things to different people. One of the key ways the term is used is within linguistics where it primarily refers to taking a chunk of language larger than a sentence as an object of study.  That was a familiar concept to me, and more or less what I was looking into at that time, but I was a little surprised and mystified to discover that the term had also been taken up by different branches of social science and manifested itself as different methodologies.  Since then I’ve paid attention to different ways that the term “discourse” and “discourse analysis” is used.  In fact, it is a major research interest of mine now. By the time I began reading The Archeology of Knowledge I was already vaguely familiar with Foucault’s use of “discourse” as a philosophical concept, but I wasn’t aware until I did a little Googling that the concepts in this book have had a great deal of uptake in terms of what is now called “Foucauldian discourse analysis,” or as one recent online article put it, “FOUCAULTian discourse analysis” (weird capitalization in original). In fact, this article was quite interesting in capturing how Foucault’s method of analysis has been taken up in several national contexts—France, Germany, Great Britain, Austria and Netherlands, and Spain. It doesn’t talk much about the US, except to call the country an “underrepresented area” in terms of surveys like this one and to note that the impact “is enormous and the methodological orientation toward discourse analysis is increasing" (Diaz-Bone et al, 2007).   

Concepts of network, or why does this book fit this course

When I first started reading this book, I saw it as highly relevant to my research interests, to looking at how disciplinary discourses construct and are constructed by disciplinary beliefs and values.  What was less obvious to me was how the book fit a course in network theories. Spinuzzi and genre theory seem a reasonable fit since many genre theorists work within the framework of Activity Theory, and I think this is at least partially the case for Spinuzzi (2003).  Activity Theory is an ecological approach that connects moving parts in a network sort of way.  I figured Latour (2005) made sense. After all, the word “network,” is in the title and ditto for Castells (1996).  And Rickert (2013)? Well, the word “ambient” sounds dispersed and web-like.  But Foucault was less obvious as an inclusion.  In fact, most of the time when I was reading this book, the idea of network was not at the forefront of my mind.  However, there are some places where Foucault does explicitly use the term “network”. 
First, he discusses the idea of books as a “node within a network” (p. 23).  Interestingly, too, a book is not seen as the same kind of node in each type of discourse because different discourses are constructed differently.  Later, subjects are seen as situated within a “certain grid,” and, later on the same page, notes that a subject can occupy different positions  “in the information networks” (p. 53).  The next chapter discusses concepts in terms of “conceptual network” (p. 62), how concepts are established in relation to one another within a theory, a discipline or an approach at a given point in time.  Much later in the book, in the chapter, “Comparative Facts,” the idea of network is even more salient. Here Foucault discusses how different disciplines, institutions, and practices can be analyzed in different ways, and it is possible to reveal more than one “interdiscursive network” (p. 159). Finally, in contrast with the history of ideas, archeology maps rules of formation such as the principle that sometimes rules can only appear after others make room for their appearance.  In other words, “the archeological ramification of the rules of formation is not a uniformly simultaneous network: there exist relations, branches, derivations that are temporally neutral; there exist others that imply a particular temporal direction” (p. 169).
As I look back over my notes, I see that noticed them as I read.  Otherwise, they wouldn’t be in my notes, of course. By the same token, they are much more salient to me now as I cast my mind back over the entire book.  I can see how Foucault is primarily discussing connections and sets of relations—statements within a discourse, subjects in discursive spaces, connections between concepts, etc.   The notion of network is both explicit and implicit throughout.

894 Reading Notes: How Stuff Works

“How Ethernet Works”: Useful terms

This article by Nick Pidgeon (2000) was the best overview for the basic terminology, as below:
o   Local Area (LAN) usually within a building
o   Wide Area (WAN) think two local libraries, for example
§  Fiber optic connections are blurring distinctions between two because of increases in speed, efficiency
o   Protocol—set of rules governing connections, must be shared by devices on networks; establish rules for constructing frames
§  Maximum/minimum lengths, required information (such as destination & source addresses),
§  No two devices have same addresses
o   “Broadcast address” causes all devices in network to receive; otherwise, devices discard messages not intended for them (though they do “see” such messages if connected to medium)
o   Medium—cable, whether coaxial copper or fiber optic
o   Segment—contains a single shared medium (i.e. cable)
o   Node—devices that attach to a segment
o   Frame—chunks of information communicated between nodes

Tone of techno-topia: “How Home Networking Works” and “How Wireless Mesh Networks Work”

The first article are I read was Wilson & Fuller’s 2001 article on home networking.  It was pretty straightforward. Most of the terms and concepts were not particularly new for me. I did, however, find the discussion of advancements in the technology for healthcare and housing to be interesting.  Although some of the affordances that the technology offers for healthcare providers to monitor patients at home and for homeowners to control climate and security options for their homes while they are away were really interesting, the slightly overawed tone put me off a little.  In fact, I also found the same tone in Roos’ article, “How Wireless Mesh Networks Work” (2007).  To be fair, he was talking about some of the ways that wiring things that I’d never imagined wiring offers new opportunities, it reminds me a little of the how-we-are-all-going-to-be-living-in-the-future children’s books that I remember seeing when I was a child.  I don’t think that sort of techno-topia is quite as common now, but new and cool stuff still does have a tendency to make people gush a little. 

Maximizing interactivy: “How Wireless Mesh Networks Work”

I do want to summarize a few points in Roos’ 2007 article on wireless mesh networks, though, because these were new to me.  The main thing that struck me was that by using the presence of proximate devices and by populating the space with a number of small wi-fi transmitters that wireless capability surprisingly can offer more efficient transmission than dedicated cables.  This made sense when I thought about it, but it wasn’t something that would have automatically occurred to me.
I was impressed with the many benefits that wireless mesh networks can provide, for example:
o   Works with all types of devices.  I’d always thought of network nodes being primarily desktop work stations, but here printers and smart phones and scanners and what-have-you can not only receive but also pass on information.
o   For urban areas, mesh nodes on street lights and stop lights can be used by emergency workers when phone or cell service is down.
o   Can also be used for diagnostics on power, water supplies without the need to dig and run lines.
o   Can be used in developing countries as alternative to physical phone system; solar-powered nodes can obviate need for electricity and connect to satellite or cellular system.
o   Good for colleges because require fewer wired locations and improves bandwidth for sharing larger files (i.e. apparently can break up packets and send multiple directions to reunite later (if I understand correctly)).
o   Also good for densely populated buildings, institutions like hospitals, hotels, etc., where dense mesh connections can be built up instead of wiring everything.
o   Good for temporary and outdoor venues.
o   Good for keeping inventory with scanning devices in large warehouses.
o   There are probably future military uses for battlefield surveillance networks (i.e. devices dropped into various battlefield locations)
Maximizing the interactivity does seem to have a downside in my opinion.  Surveillance devices in this type of a setting kill two birds with one stone.  They can service as additional network devices, increasing transmission options.  Of course, they also do their normal surveillance job.  Surely this will increase the likelihood of making public spaces even more capable of tracking us than they already are.  Most of us—I am not an exception—love the idea of maximizing connectivity and all the conveniences of a fully-wired space.  On the other hand, I do feel a sense of disquiet about the electronic eyes watching me.

Topologies: “How Hybrid Networks Work”

Several articles discussed topologies, such as the star topology and the token ring, but this one was particularly helpful in clarifying these concepts for me.  I found the pros and cons of the different arrangements interesting, for example, the central hub of the star topology allows for certain efficiencies of centralization, but the one-way traffic of the token ring prevents collisions on the same segment.  I think the topologies probably can be leveraged into productive metaphors, but I don’t yet know what these might be.

Emerging concepts: What I’m noticing so far

First, I have noticed two opposing principles, somewhat ironic in their opposition, the principle of materiality and the principle of invisibility.  First, networks—computer, water, electric, social—all have actual physical nodes even as the conduits may be less obviously physical (wi-fi).  Second, the material aspects are largely invisible.  The cables are in the walls, underground, out of sight.  Reductions in size also allows network connections to weave themselves more firmly into the fabric of our lives while becoming less and less visible.  I was reminded of a book that I bought quite a while ago, Beneath the Metropolis, describing underground conduits, ancient and modern, that run under world cities such as New York, Mexico City, Paris, Cairo, Tokyo and others (Marshall & Emblidge, 2006).  The book describes subway tunnels, aqueducts, underground shopping centers, escape tunnels, sewers, even tectonic plates.  Although the book doesn’t particularly go into fiber-optic cables and things like that, clearly these are also similarly invisible and equally important.
I had a personal experience that illustrated the principle of materiality, at least in relation to submarine communication cables.  I was visiting Vietnam for 10 days over Christmas in 2006, and I ran out of money. Frustratingly, my credit card stopped working. The reason, I was told, is that there had been an earthquake in Taiwan.  The irony is that I lived and worked in Taiwan, but the earthquake affected me more than it did my friends back in Taiwan because it had snapped the submarine cable that Vietnam depended on for the internet and rendered my credit card unusable. In the end, I had to call my boss in Taiwan and have him wire money to a bank in Vietnam, and I had to take a motorcycle taxi to another city to pick it up.  I’m not sure exactly how wiring money got around the issues with the cables, but at any rate, my plan B worked, and I was able to finance the rest of my trip.

Networks represented? Art connections

For some reason, this initial discussion of computer networking also got me thinking of art, I’m not sure why.  I thought of Kandinsky because the style of his art reminded me of networks.  

Wikimedia commons image: Vassily Kandinsky, 1923 - Composition 8, huile sur toile, 140 cm x 201 cm, Musée Guggenheim, New York.jpg

Searching out Kandinksy I found a fascinating article from MOMA with a network showing the genealogical relationship between Kandinsky and many of the other abstract artists who influenced him or that he influenced.  I also went searching for and found a contemporary artist doing what is described as new media art.  Deborah Aschheim does mixed media networks using digital devices and sculpture, all in an attempt to represent memory as a neural networks.

How Stuff Works: Computer Networking Basics

Computer networks: basic terms

I chose the concept of “networking,” since it appeared to be the only one of my three selections that was on no one else’s list.  “How Stuff Works” took the concept of networking first as a computer term—not surprisingly—but also generated links to social networking, which is just a small leap to another category of digital networking, namely, social media.  Adding a descriptor or two generates other types of networking, in some cases metaphorical extensions of the computer network and in others separate emergences such as telephone or TV networks.  However, because of the primacy of the concept as associated with computer devices connected by cables, I took my explorations in that direction.  The most useful article I consulted, Nick Pidgeon’s (2000) “How Ethernet Works,” was neither the newest nor the first that I consulted, but I found it uniformly useful for establishing key concepts and terminology.    Although networks can be classified as Local Area Networks (LAN) (generally used by a single organization and often within a single building or office) or Wide Area Networks (WAN) (interconnected networks or the internet itself), the same components make up each type.  Lines connecting entities in a network are known as medium, typically a cable, whether coaxial copper cable or fiber optic cable, and a single section of cable connecting two devices is called a segment.  The devices attached to segments, such as a desktop work station or a printer, are called nodesFrames are chunks of information that are communicated between nodes.  Protocols are rules used for constructing frames and for governing connections.  Networks also contained dedicated devices used for controlling the flow of information or passing on information.  These include things like repeaters and bridges, particularly in Ethernet networks.  I also suspect that these are more relevant to earlier networks that were entirely wired (pure Ethernet networks, in other words).  After all, the technology has changed since the time this article was written.  In any case, the more important component for the smooth functioning of networks is the router.  There are smaller, limited versions of these as well as larger powerful versions for large networks and relay points, but in any case, routers are what controls the passage of information, the “crucial device that lets messages flow between networks” (Franklin, 2000).  Routers keep information moving towards its destination but also prevent it from clogging channels or going where it isn’t needed.  In other words, a router is not only a mail carrier but a traffic cop, so to speak.  Information travels through computer networks in packets.  In contrast with a land line telephone call which makes a stable circuit to phone being called, this means that messages are chopped up into manageable sizes and sent in pieces via any efficient route.  It is the routers that send along the packets through maximally efficient routes (Franklin, 2000).  On reach the destination device, packets are reunited to reconstruct the original message.

Network layout and network types

An aspect of networks that emerged as a key element in general was the set-up or the structure of the network.  However, it became apparent to me that from the time that the earlier articles were written that some concerns had diminished.  For example, Pidgeon’s 2000 article on Ethernet discussed radial, or branching set-ups where devices connected in a hierarchical way, back to central hubs, or a token ring set-up where devices are arrayed in a non-hierarchical, circular arrangement and signals are sent one-way around the circle until a destination is reached.  Another term used for a radial type arrangement with a central hub is star topology, mentioned in a 2008 article on hybrid networks (Roos, 2008).  

Establishing a set-up to avoid overworking the same segments with multi-direction traffic was an issue that led to strategic arrangements like the star topology or the token ring.  However, mesh networks take what was a weakness in the past—too many things connecting to too many other things—and have built it into a strength of densely-populated hybrid networks.  Traditional hybrid networks (Roos, 2008)) are networks where some components are connected by Ethernet cables while others are connected wirelessly.  A challenge of hybrid networks is to get a wi-fi signal of adequate strength and to avoid security risks.  Users of home networks are also warned that wireless is slower (Wilson, 2001). Mesh networks, on the other hand, are flexible, densely-populated networks built on relatively few wired connections and a plethora of wireless devices.  

Because of the availability of a large number of devices that can receive and transmit wireless signals, these networks are actually faster and more efficient, say their proponents (Roos, 2007).  Unlike the earlier wired networks, the mesh networks are not limited to single routes on cables but can pass packets in multiple routes using multiple proximate devices.  Due to the use of small wireless radio transmitters that can be stashed in various locations and don’t require burying cables or digging into walls, many large and densely-populated locations are moving towards mesh networks.  Some examples are hospitals, hotels, college campuses, warehouses and even municipal spaces.  In fact, Roos (2007) seems to see mesh networks as a positive development for an increasingly wired future, not only making urban areas better connected and safer since wireless signals will resist challenges to other infrastructure breakdowns, but also as powerful solutions for less developed countries and remote areas.  One cannot help suspecting, however, a flip side in terms of ever greater concerns for privacy.

Emergent concepts

Several things struck me as I read about how computer networks work in a fundamental sense.  First, while computer networks—particularly with the increase of wi-fi options—enable a sense of ubiquitous connectivity in most of the spaces we inhabit, there is, in fact, a level of materiality that is inescapable.  Devices that receive and transmit signals are things we can hold in our hands and some things are always going to be wired.  Related to this is the idea that layout matters.  Where things are positioned in relation to each other matters. Another concept is the idea of flow of communication, of messages, of information, passing back and forth. With that being the case, efficiency is crucial and security is also a relevant issue.  All of these variables require an element of decision-making by real human beings who construct and maintain networks.  While there is certainly an evolution and apparent randomness, there is also agency.
In New Media: The Key Concepts, sociologists Nicholas Gane and David Beer (2012) discuss six core concepts related to new media. The first concept that they choose is “network,” and they begin their discussion with computer engineering, arguing that although the term has become a trope in cultural and social sciences, it is meaningfully traced back to the computer science. Their discussion begins, therefore, with a few—though not all—of the basic terms that I selected for my very simple discussion above.  As metaphor and as theory, we can take these terms as concepts and run with them in different directions, but I believe that it will be helpful at least to consider their material starting point as rooted in computer science.
