[2b2k] Echo chambers and the importance of like-minded thinking

I’ve found the argument against Echo Chambers to be vexing.

On the one hand, I of course agree that it’s bad for us all when we only hang out with people whose views we share, because this tends to confirm us in our beliefs and even makes those beliefs more extreme.

On the other hand, I disagree with our Western liberal assumption that a genuine conversation is one in which we encounter radically opposite viewpoints with an open heart and mind. No, when I want to understand the meaning of, say, a court ruling about gay marriage, I’m not going to go first to a site that thinks homosexuality is a damnable sin. I’m going to go to my nearest local “echo chamber.” Understanding is incremental. It fits the new into our existing context. That’s how understanding works.

I find a great deal of truth in a passage sent to me by a friend of mine. (I’ll replace that phrase with his name once I’m able to reach him to ask permission). It’s a passage by Swami Vivekananda, “from his book Raja Yoga, a modern study of the founding text of yoga (India, approx 400 CE).” My friend continues, “In it S. Vivekananda is commenting on one of the first of the yoga sutras, which outlines the path the prospective adept must walk.”

“What is meant by study in this case? No study of novels or story books, but study of those works which teach the liberation of the Soul. Then again this study does not mean controversial studies at all. The Yogi is supposed to have finished his period of controversy. He has had enough of that, and has become satisfied. He only studies to intensify his convictions. Vâda and Siddhânta — these are the two sorts of scriptural knowledge — Vada (the argumentative) and Siddhanta (the decisive). When a man is entirely ignorant he takes up the first of these, the argumentative fighting, and reasoning pro and con; and when he has finished that he takes up the Siddhanta, the decisive, arriving at a conclusion. Simply arriving at this conclusion will not do. It must be intensified. Books are infinite in number, and time is short; therefore the secret of knowledge is to take what is essential. Take that and try to live up to it.

There is an old Indian legend that if you place a cup of milk and water before a Râja-Hamsa (swan), he will take all the milk and leave the water. In that way we should take what is of value in knowledge, and leave the dross. Intellectual gymnastics are necessary at first. We must not go blindly into anything.

The Yogi has passed the argumentative state, and has come to a conclusion, which is, like the rocks, immovable. The only thing he now seeks to do is to intensify that conclusion. Do not argue, he says; if one forces arguments upon you, be silent. Do not answer any argument, but go away calmly, because arguments only disturb the mind. The only thing necessary is to train the intellect, what is the use of disturbing it for nothing? The intellect is but a weak instrument, and can give us only knowledge limited by the senses. The Yogi wants to go beyond the senses, therefore intellect is of no use to him. He is certain of this and, therefore, is silent, and does not argue. Every argument throws his mind out of balance, creates a disturbance in the Chitta (consciousness), and a disturbance is a drawback. Argumentations and searchings of the reason are only by the way. There are much higher things beyond them.

The whole of life is not for schoolboy fights and debating societies. “Surrendering the fruits of work to God” is to take to ourselves neither credit nor blame, but to give up both to the Lord and be at peace.” (Raja Yoga, ch 2, comment to verse 1)

[2b2k] Agre on minds and hands

I recently published a column at KMWorld pointing out some of the benefits of having one’s thoughts share a context with people who build things. Today I came across an article by Jethro Masis titled “Making AI Philosophical Again: On Philip E. Agre’s Legacy.” Jethro points to a 1997 work by the greatly missed Philip Agre that says it so much better:

…what truly founds computational work is the practitioner’s evolving sense of what can be built and what cannot” (1997, p. 11). The motto of computational practitioners is simple: if you cannot build it, you do not understand it. It must be built and we must accordingly understand the constituting mechanisms underlying its workings.This is why, on Agre’s account, computer scientists “mistrust anything unless they can nail down all four corners of it; they would, by and large, rather get it precise and wrong than vague and right” (Computation and Human Experience, 1997, p. 13).

(I’m pretty sure I read Computation and Human Experience many years ago. Ah, the Great Forgetting of one in his mid-60s.)

Jethro’s article overall attempts to adopt Agre’s point that “The technical and critical modes of research should come together in this newly expanded form of critical technical consciousness,” and to apply this to Heidegger’s idea of Zuhandenheit: how things show themselves to us as useful to our plans and projects; for Heidegger, that is the normal, everyday way most things present themselves to us. This leads Jethro to take us through Agre’s criticisms of AI modeling, its failure to represent context except as vorhanden [pdf], (Heidegger’s term for how things look when they are torn out of the context of our lived purposes), and the need to thoroughly rethink the idea of consciousness as consisting of representations of an external world. Agre wants to work out “on a technical level” how this can apply to AI. Fascinating.

Here’s another bit of brilliance from Agre:

For Agre, this is particularly problematic because “as long as an underlying metaphor system goes unrecognized, all manifestations of trouble in technical work will be interpreted as technical difficulties and not as symptoms of a deeper, substantive problem.” (p. 260 of CHE)
