The 2006 Best of Web 2.0

22:06:23 :: [technology &c.] :: 206 words

Designtechnica has published their list of favorite Web 2.0 sites out there and categorizes them. Topping the list includes Digg.com, Flickr.com, Vimeo, and several others. Congratulations to these site.

The most important site, IMHO, is Meebo—an online IM client. According to Designtechnica,

Meebo is an AJAX-based chat client with which you can use AIM, Google Talk, Jabber, ICQ, and more. A great aqua-like interface and the ability to do all of this without technology such as Java is a real asset when on the go. No refreshing occurs while dragging around IM windows or viewing your friend’s information. The chat works great, too, and is perfect for people who are not allowed to install chat clients on work computers. You can even set messages away and leave your browser window open. It’s a very valuable tool that won’t leave any breadcrumbs, letting people know you were chatting it up.

In other news, IntelliTXT is the worst invention since animated banner ads.

Psycholinguistic Differences in Dialect

02:20:46 :: [language & linguistics] :: 174 words

“Rice University study focuses on merged vowel sounds in different dialects.”

I’m working in the psycholinguistics lab at the University of South Carolina, so this kind of research is right up my alley. This is a novel study because it shows that people from different dialects of the same language (for instance, Appalachian versus Boston English) have the same kinds of trouble as non-native speakers to a secondary language. (E.g., the Japanese and “L” and “R” sounds in English, rendering the name of this language, “Engrish.”)

This phenomenon also happens in listening to music—if your untrained, Western ears are used to piano and you hear an indigenous Indian instrument (the name of which I have forgotten), there are notes so close together that the untrained ear can’t hear them.

If you’re interested in linguistics, language-learning, or psycholinguistics, check out the article.

Dynamic PHP (Tricks Java/C#/C++ Don’t)

22:58:50 :: [technology &c.] :: 221 words

PHP V5’s new object-oriented programming features have raised the level of functionality in this popular language significantly. Learn how to use the dynamic features of PHP V5 to create objects that bend to fit your needs.

The introduction of new object-oriented programming (OOP) features in PHP V5 has significantly raised the level of functionality in this programming language. Not only can you have private, protected, and public member variables and functions — just as you would in the Java™, C++, or C# programming languages — but you can also create objects that bend at runtime, creating new methods and member variables on the fly. You can’t do that with the Java, C++, or C# languages. This kind of functionality makes super-rapid application development systems, such as Ruby on Rails, possible.

PHP fascinates me. I don’t have time to learn it right now, obviously, but it looks like the best of C++ and Perl combined into one, Web-friendly language. (Any seasoned veterans care to add to, or correct, that point?) With OOP integrated into version 5, this looks like a summer project….

How to Subscribe to TV Shows Using The Democracy Player, Bittorrent, & RSS

21:47:56 :: [technology &c.] :: 122 words

The Democracy Player is an amazing open source Internet TV application that allows you to subscribe to video RSS feeds from anywhere on the web. With a little hackery, The Democracy Player will make you wonder why you’re still paying your cable bill.

I’m not paying for cable, as I don’t really watch TV, but I’m still curious about this. Also curious about the legality. I’ll report back about whether this has worked for me, just as soon as I get some more philosophy read….

Study Shows Brain Anticipates Taste, Shifts Gears

21:41:44 :: [psychology] :: 205 words

“As the prism of our senses, the human brain has ways of refracting sensory input in defiance of reality. […] How the brain processes this faked input and prompts the body to respond is largely a mystery of neuroscience.”

This almost impenetrably verbose description means to say that, the power of expectation is, once again, shown to be underrated.

Assistant professor of psychology and psychiatry at the University of Wisconsin at Madison, J. B. Nitschke, tested 43 undergraduate participants’ fMRI reactions to solutions of quinine, sugar, and plain water when introduction of the stimulus into the mouth was preceded by a visual stimulus (plus, neutral, or negative) that participants used to anticipate the sweetness or bitterness of the solution.

Turns out, if the participants were expecting a non-bitter or less-bitter solution, they would perceive the solution thus, even if it had the same concentration of quinine as before.

Desktop Earth

23:35:17 :: [technology &c.] :: 103 words

Desktop Earth generates custom-resolution wallpapers based on NASA’s Blue Marble Next imagery. You can generate wallpaper that is a current snapshot of the Earth, specify your resolution, and you get a custom-sized PNG image. The Windows version takes up about 4MB RAM at all times, more when it’s updating, but the “cool factor” may make it worth it for the astronomy geeks. You can also generate one wallpaper at a time on their website.

Quidquid latine dictum sit, altum videtur

03:14:18 :: [theology] :: 127 words

I was just looking through some Latin Quotes, Latin Phrases, Latin Mottos and Latin Quotations at the site through the link, looking for the correct spelling of the tongue-in-cheek title of this post (”Whatever is said in Latin sounds profound”), when I came across one that particularly struck me: “Abyssus abyssum invocat.”

Hell calls hell. (Meaning colloquially, according to the aforelinked site, “one misstep leads to another.”

And it hit me. If the Christian church still thought in terms like this, calling sin what it is and not pulling any punches, talking in these kinds of terms about things that actually are that serious, seems like we’d have a lot fewer lukewarm Christians.

Technologist Manifesto (Things Everyone in IT Should Know)

23:09:07 :: [technology &c.] :: 140 words

Technologist Manifesto, or Things Everyone in IT Should Know

After slogging through article after article about watered-down techniques for this, that, and the other, I’m always refreshed when I come across an iconoclastically humorous article.

Take, for instance, this excerpt:

When (not if) a user asks “This sounds like a lot of extra work, how will it make my life easier?” you have an opportunity to evaluate your career progression.

If your answer is something akin to “It’s policy, you have to do it or you’ll get fired.” then I hope you’re drinking your Red Bull from a sippy cup, Junior.

If your answer is more like asking the question “Why is it so hard to use?” then you may be ready for big boy underwear.

Enjoy.

Marx’s Most Famous Remark

23:59:34 :: [theology] :: 390 words

Before I knew anything else about Karl Marx, I knew he was the father of communism and that he had said, somewhere along the line, “Religion is the opiate of the masses.” Most people that haven’t made it a point to study nineteenth century philosophy, I would venture, are similarly informed. But it still bugs me that in any discussion about religion, so many proud atheists are willing to spout this one quote as though it were the Gospel truth, any deviation is clearly irrational, end of discussion.

So in the discussion about DNA & Mormonism (see this post), when someone quoted Marx and then said, “Nothing else needs to be said. I’m not saying anything is right or wrong, but you can not tell me that statement is false.”—I responded as follows.

Actually, I can, and so can you. Think about it for a minute. What Marx was saying was that religion provided a structure of authority to keep people from thinking too much, &c., &c. Wait, hear me on this: I think in a lot of cases, that’s true, or can be.

But I don’t think it’s true overall. How much time do the people of the world spend thinking about religion and religious issues? Even the idea of atheism as a valid theological position wasn’t accepted till the past 200 years or so. Sure, sure, this proves nothing from the modernist viewpoint, since modernism is the “new era” of understanding the world from a scientific perspective, and so forth.

The point is, everyone who subscribes to any faith is called by people of other faiths (this means Christians and Muslims, Jews and atheists, Mormons and agnostics, Baha’i and Sikhists) to give an account of why they believe what they believe. If both parties aren’t scared by their own ignorance out of conversation, even in arenas where extremely cogent debates can take place in a civil, respectful, beneficial way, different ideas that are this foundational cause deep unrest and, thus, more conversation (and more thinking).

We all know what Marx was driving at, maybe we can even agree with it on certain accounts, but if there’s been anything in the history of humanity that’s stirred up more controversy, war, debate, and even individual introspection, I don’t know what it is.

DNA and Mormon Scripture

23:17:45 :: [theology, technology &c.] :: 100 words

This story has caused almost a thousand diggs and innumerable comments. Essentially, for those of you just joining the story, DNA test results have shown that Native Americans could not have been descendants of a lost tribe of Israel, since there is essentially nothing Semitic in their blood.

Mormons and the Mormon Church are dismissing this as heresy, others are pointing and laughing, but it’s certainly worth investigating.

A Tampa [FL, USA] 7th grader compared the bacteria levels found in toilet water [water from a commode, not “eau de toilette”] with ice served at several local fast food restaurants and found it might be safer to slurp from the throne!

So if the stories about McDonald’s trans-fatty fries and all the other nonsense that goes on in the fast food service industry aren’t enough to keep you buying fresh or eating granola bars on the run, maybe this is. Props to the young lady who did this experiment.

Putnam’s Mental Functionalism

20:27:08 :: [psychology, philosophy] :: 665 words

Engagement Paper 3: Hilary Putnam’s The Nature of Mental States

(1) “Since I am discussing not what the concept of pain comes to, but what pain `is’, […] I shall not apologize for advancing an empirical hypothesis. Indeed, my strategy will be to argue that pain is not a brain state, not on a priori grounds, but on the grounds that another hypothesis is more suitable. […] I shall, in short, argue that pain is not a brain state, in the sense of a physical-chemical state of the brain (or even the whole nervous system), but another kind of state entirely. I propose the hypothesis that pain, or the state of being in pain, is a functional state of the whole organism.”

(2) Putnam argued against the identity theorists like Place, who believed that all mental states were brain states, that is, that neural processes were the constituting factors that made up consciousness, perception, and anything else that we might otherwise ascribe to the “mind” (as opposed to the body). However, Putnam’s arguments are not dualistic (though he himself concedes that functionalism as he puts it forth is not altogether incompatible with dualism), but they do go a step beyond identity theory. Whereas identity theorists and logical behaviorists put a strictly materialistic bent on the understanding of the mind, Putnam wants to argue that there is much more to mental states than just describing them in physicalist terms. He does, though, concede that physical descriptions are a good start, and a valid foundation for discussing the mind. The identity theorists took up functionalism as Putnam has advanced the theory, saying that if the mind does have functional states, then it’s very likely that they are describable in physical terms. Putnam wants to argue that mental states or brain states as descriptive of human experience are not as effective as descriptions of functional states of an organism. That is to say, regardless of the physical state of an organism (viz., that organism’s brain), what makes a mental state one of a particular kind is not described by the way it is constituted physically, but by the role it plays in the full system of which that mental state is a part. Thus, pain is not strictly a brain state, but rather a functional state or disposition of an entire organism.

(3) With this and articles like it, Putnam combined an Aristotelian conception of the soul with a budding interest in computers and in the idea of Turing Machines to describe human behavior and brain states. (Alan Turing, in the middle of the twentieth century, conceived of a hypothetical computer with an infinite amount of storage that could, through simple logical and mathematical operations, modify its own operating code. This computer model was a Turing machine.) Functionalism allows for beings that are not human or that don’t have brains like humans to experience, for instance, pain: pain can be multiply realized, that is, even machines or different life forms could be said to be in pain if their functional state is like that of the human (as opposed to the neural state being like that of a human). Putnam argues that functional states are also not simply behavioral dispositions, and that that argument is like arguing that heat is not molecular kinetic energy simply because people do not necessarily or normally think of molecular kinetic energy when thinking about heat. It is not necessary, he argues, to think of a given thing in a certain way in order for it to be described accurately in that way. Functionalism as a movement in psychology played an integral role along with advances in computer science in furthering artificial intelligence research. If non-human animals, or even life forms with different bases, could have mental states like pain from a functional standpoint, what would be the inhibition to making the leap from those organic life-forms to computers? Functionalism, then, as Putnam advances the theory, is a different way of thinking about the mind.

Place’s Identity Theory of Mind

17:29:51 :: [psychology, philosophy] :: 758 words

Assignment: (1) select a cogent passage from a part of a work we’re reading [in philosophy of mind, PHIL 520]; (2) accurately explain what this passage says; and (3) explain how it fits with the gist of the entire article.

Engagement Paper 2: U. T. Place’s Is Consciousness a Brain Process?

(1) “[…] the philosopher is unlikely to be impressed by the considerations which lead Sherrington to conclude that there are two sets of events, one physico-chemical, the other psychical. Sherrington’s argument […] depends on a […] logical mistake […]. This logical mistake, which I shall refer to as the ‘phenomenological fallacy,’ is the mistake of supposing that when a subject describes his experience, when he describes how things look, sound, smell, taste, or feel to him, he is describing the literal properties of objects and events on a peculiar sort of internal cinema or television screen, usually referred to in the modern psychological literature as the ‘phenomenal field.’”

(2) The phenomenological fallacy, the way Place describes it, makes any attempt to characterize that which exists in the world by verbal report alone as absurdly contrived as Descartes’ “clear and distinct” ideas, and no doubt that’s the end to which Place is aiming. When we describe the world around us, we make the mistake according to Place of believing that what we are describing are the actual properties of the things. This may seem unequivocally true intuitively, but there are certain limitations on the way that we perceive things. For instance, even though a rational human being with moderate experience can give a fairly good estimation of the length, breadth, and depth of an object in space if he has encountered objects like it before, carpenters and contractors haven’t stopped using tape measures, plumb lines, and bubble-levels. Colorblind individuals cannot correctly assess the colors of certain objects—but even this way of phrasing implies that there is a “correct” color, which is fallacious in itself, it seems, for Place: when we report the color of an object and our friends and spectrographs agree, that proves only that the majority of minds perceive the reflections of certain wavelengths of light off of various objects in a comparable way. So the discussion of a phenomenal field is, for Place, utter nonsense: we want to ascribe our consciousness to some ethereal place, hidden somewhere metaphysical, away from our bodies, drawing judgments about stimuli and directing the body to act on them in various and sundry ways. But this common way of speaking, he says, is mythological, folk nonsense. Place postulates that our there is no difference between the brain itself and all the mental factors to which the brain gives rise, i.e., that the answer to the question he poses in the title of his article is affirmative: consciousness is a brain process.

(3) Place was a pioneer of the identity theory of mind, the idea that brain processes could explain every mental state, intention, and mode and aspect of operation. In this paper, Place likens the debate over the mind being more than the constituent neurons that make up the brain and the interactions between them as being the same as a debate over whether lightning is an electrical discharge. Calling lightning “lightning,” he says, doesn’t diminish the fact that it is an electrical discharge; and knowing that lightning is an electrical discharge doesn’t diminish the fact that we can talk about it as lightning. So it is with the mind: we are merely arguing over two different ways of speaking about an identical thing when we distinguish between brain processes and consciousness. This article attempts to set forth that argument by various means. The point at which he talks about the phenomenological fallacy is perhaps the most convincing part of the article, where he admonishes his readers not to carry such folk notions as of our bodily perceptions being paraded in front of our souls in the theater of the mind; but rather, he says, we can more accurately talk about and describe the things we perceive in different terms. Specifically, we can only say that we are having an experience like the others of which we have been conscious in which we perceive a like object. For instance, in the case of a green afterimage, we are not seeing something green, but only experiencing something like when we see something green. In this way, Place argues, we will be talking with more accuracy about the experiences of our brains, since we will be using one brain process to describe another.

“8088 Corruption”

From the old-dog-new-tricks dept.

Color video running at 30 frames per second, with audio, on an original 4.77MHz 8088 IBM PC Model 5150 with 640K RAM, CGA video, 10MB drive, and Sound Blaster Pro.
No tricks, this is for real! This kind of speed is only achievable using text mode (!) and 8088 assembler.
Programmer: Jim Leonard

That’s right, that’s six hundred forty kilobytes of RAM. Right. The video is great.

Can humans likewise expand our mental capacities or acquire new habits in this kind of dynamic way? I’m becoming less cynical on the topic. Gradually.

Descartes’ “Passions of the Soul”

13:57:59 :: [philosophy] :: 798 words

Assignment: (1) select a cogent passage from a part of a work we’re reading [in philosophy of mind, PHIL 520]; (2) accurately explain what this passage says; and (3) explain how it fits with the gist of the entire article.

Engagement Paper 1: Descartes’ The Passions of the Soul

(1) “But … I have clearly established that the part of the body in which the soul directly exercises its functions is not the heart at all, or the whole of the brain. It is rather the innermost part of the brain, which is a certain very small gland situated in the middle of the brain’s substance and suspended above the passage through which the spirits in the brain’s anterior cavities communicate with those in its posterior cavities.”

(2) The gland to which Descartes is so famously referring here is the pineal gland, a very small part of the brain which he thought was responsible for the connection of the soul to the body. It was, for Descartes, of particular significance that the pineal gland was not only located in the middle of the “brain’s substance,” but that it also had no double in the rest of the body or, specifically, in the brain. Whereas the other parts of the brain had their left and right halves, and the body its left and right halves, the pineal gland to Descartes’ thinking was utterly unique in that there was not a left and right side to the little gland. It was through this little node of flesh in the brain, thought Descartes, that the soul commanded the body and the body relayed its impulses to the soul, or mind (for Descartes, the two were synonymous). This was directed against the common notions of his day that the body was directed by the brain (or more accurately, perhaps, the mind which was identical with the brain), or by the heart, “because we feel the passions in it,” as he says.

(3) Descartes believed, quite famously, that the body and the mind were two distinct elements of a human being, each of which is “conjointly united” to the other in a direct one-to-one ratio. The comparison has been drawn that make the soul and the body two independent clocks keeping exactly the same time, but which are not connected to each other in any interdependent or substantially meaningful way. In The Passions of the Soul, Descartes is trying to prove that the passions are communicated to and felt in the body because of the soul, but that the soul and body were absolutely disconnected from one another except through the small cerebral appendage called the pineal gland. “Animal spirits” inside of our bodies functioned for Descartes in the same way that we understand neurons, synapses, and electro-chemical impulses acting within our bodies in our current psychophysiological understanding. The pineal gland is, according to Descartes, the channel to which the spirits that conveyed our sensory impressions could flow. When, for instance, an object was presented to us, two images—one from each of our eyes—would be conveyed by the animal spirits within our bodies up to the pineal gland, which would then transmit a direct image of our impression to the soul, which would comprehend it as whatever the object was. There was, of course, no explanation for how the pineal gland itself conveyed notions to the soul, per se. To Descartes, the important part was that the soul felt passions, that is, emotions and so forth, and then sent the body signals (through the pineal gland) to act on those passions. Certain pores in the pineal gland could be stimulated only by the soul itself, such that depending on the prior actions taken by the individual as a whole when the soul had previously been presented with such-and-such a passion, it would choose this or that course of action. It should be noted that the now-ridiculous elements of his theorizing, the animal spirits and the pores of varying sizes of the pineal gland and even of the pineal gland being the center of the mind-body interaction perhaps only seem so to us because they come so very close to the truth: if we replace the notions of the “animal spirits” with electrochemical synaptic signals, for instance, and if we replace the theoretical underpinnings of the pores of the pineal gland widening or narrowing depending on experience, we can almost see hints of an explanation for neurotransmitters and behavioral learning. Now that we know that the pineal gland itself is not solely responsible for the connection between mind and body, it seems we are humbled by how close we still are to Descartes: the arguments still rage about how the mind and the body are connected, even though we now understand neurotransmitters, synaptic clefts, and neuron interconnectivity.
