The sources of silence

I listed here many of the teachers and thinkers whose influence I have felt.   In his wonderful new book on John Cage’s 4′ 33”, the indefatigable Kyle Gann says this (pages 71-72):

The meme that Cage was more of a music philosopher than a composer has become commonplace, most of all, it seems, among people who don’t like his music and are in need of a way to justify his celebrity.  Cage was not a philosopher in any sense that the philosophy profession would recognize, but he was very much a composer who drew inspiration for his music from philosophical ideas.  The list of artists, writers, and thinkers he names in justification of his musical trajectory is a long one:  Meister Eckhart, Huang-Po, Kwang-Tse, Erik Satie, Henry David Thoreau, Gertrude Stein, Arnold Schoenberg, John Cage Sr., Marcel Duchamp, Sri Ramakrishna, Daisetz Sukuki, Joseph Campbell, Ananda K. Coomaraswamy, Alan Watts, Antonin Artaud, Robert Rauschenberg, Morton Feldman, David Tudor, Norman O. Brown, Marshall McLuhan, Buckminster Fuller, Gita Sarabhai, and Christian Wolff, among others.”

I was reminded of James Pritchett’s intention, when writing his book on Cage’s music, as much as possible to read everything that John Cage had himself read, and in the order he had done so.

Revisionist history

The Australian Department of Defence has been accused of ignoring the religious beliefs of Australian soldiers killed in World War I currently being re-buried, by assuming they were all Christians.   This assumption is a very odd one for the DoD to make, given that the first Australian-born commander of Australian troops, General Sir John Monash, in command of all Australian forces by the end of that war, promoted to General in the field, and knighted on the battlefield (the first such elevation by a British monarch in 200 years), was Jewish.  I think the DoD needs to make a change in its burial policy and officially apologize to the affected families.




Memories of underdevelopment

Further to my post speculating about Robert Mugabe’s personality, here is some news from The Times about his physiology.  Apparently, he nods off to sleep every few minutes, even when meeting foreign visitors.  (HT:  Normblog)

The Times article mentions the two main contenders for the leadership of ZANU (PF) following Bob’s always-imminently-predicted-but-never-quite-arriving retirement:  Emmerson Mnangagwa and Solomon Mujuru.  One would think that the Zimbabwean Vice-President, Joice Mujuru, who is likewise a ZANU (PF) nomenklatura, would perhaps also be a contender, but she is married to Solomon, so he takes precedence.   She is more famous in Zimbabwe under her chimurenga name, Teurai Ropa (or Spill-Blood) Nhongo, and for leading a team of guerrilla fighters into battle while pregnant.   Because she joined the struggle (for Independence) in her teens, she did not finish high-school; to her great personal credit, she completed her O-levels after Independence and while a Cabinet Minister.   In the year she did O-level English, a novel by George Orwell was on the syllabus, leading to her infamous stage whisper at the official opening by then Prime Minister Robert Mugabe of the Zimbabwe Institute for Development Studies;  when the VIPs were led to a different (and much better) buffet than that provided for the other people present, she was heard by all to exclaim,  “But this is just like Animal Farm!”

Her husband also had a loud voice.  When I first met him, he was calling himself Rex Nhongo, and I did not then know what he looked like.  A mutual friend introduced us using only first names as we happened upon each other buying groceries one evening after work in a Greek delicatessen in the low-density (ie, formerly whites-only) suburbs of Salisbury (as it then was).  Making conversation while we stood in the queue, I asked,  “And what do you do for a living, Rex?”  In a booming voice which scared the daylights out of the white customers in the shop, he replied, “Oh, I’m Commander-in-Chief of the Army, son!”  Whether intended or not, this statement got the three of us to the front of the queue immediately.

FOOTNOTE:

Note that in maShona custom, a person may be given or may adopt different names over their life, and may prefer different names at different times or for different purposes.  In addition, for reasons of security during the liberation struggle many people adopted noms de guerre, so-called chimurenga names.

The psychology of Robert Mugabe

I wondered here whether Robert Mugabe had been an informant for CIA in the years prior to Zimbabwean Independence in 1980.   If so, many strange events in Zimbabwean politics, before and after Independence, would be explained.   The thought has now occurred to me that such a relationship, if it had existed, would also explain an odd trait of Mugabe’s personality in the period after his return from exile in December 1979.    I realize my thoughts here are pure speculation, and, moreover, speculation about another person’s personality.  

Because informants working for espionage agencies provide information on a regular basis to an employee of that agency, informants and their agents often develop quite close relationships.  Each has a secret which he or she usually cannot tell to other relatives or friends or colleagues – informants cannot usually divulge their information-passing actions to those around them, and agents usually do not divulge the names of their informants to their fellow employees.   Each also has to trust the other to some extent, and so the pair can develop quite a close relationship with one another; examples can be seen in Larry Devlin’s account of his close relationship with Mobutu Sese Seko in Zaire, and Robert Baer’s account of his time working for CIA in the Middle East.

If our Robert had indeed been an informant (paid or unpaid) for CIA, then we would probably expect the agency to release him from that relationship when he was elected Prime Minister of Zimbabwe.  If he had developed a close relationship with his agency handler, then becoming PM would mean he would no longer have a close, neutral confidant.     Is this then why Mugabe became close to Lord Christopher Soames, the temporary Governor sent by Britain to oversee the election and the transfer of power at Independence?  Their relationship became so close that Mugabe asked Soames to stay on (as Governor? as President?) for a couple of years after Independence, a request Soames declined.   Is this also why Mugabe met weekly with his political enemy, Ian Smith, for about 18 months following Independence?    Until it fell apart in 1981, their relationship was sufficiently close that they were able to dance with each other’s wives at official functions, such as the ball held for the African Parliamentary Union meeting in Zimbabwe in 1981.

The closeness of both these relationships (Mugabe-Soames, Mugabe-Smith) has always struck me as odd.   But, if true, an ex-informant seeking another regular confidant could explain them both.

Doing a PhD

These are some notes on deciding to do a PhD, notes I wrote some years ago after completing my own PhD.

Choosing a PhD program is one of the hardest decisions we can make. For a start, most of us only make this decision once in our lives, and so we have no prior personal experience to go on.

Second, the success or otherwise of a PhD depends a great deal on factors about which we have little advanced knowledge or control, including, for example:

Brautigan on writing

I am a great fan of the writing of Richard Brautigan, so I was delighted once to encounter a short reminiscence of Brautigan by that Zelig of the Beats, Pierre Delattre, in his fascinating memoir, Episodes (page 54):

The last time I saw him [RB], we were walking past the middle room of his house. There was a table in there with a typewriter on it.   ”Quiet,” he whispered, pushing me ahead of him into the kitchen. “My new novel’s in there. I kind of stroll in occasionally, write a quick few paragraphs, and get out before the novel knows what I’m doing.  If novels ever find out you’re writing them, you’re done for.”

Vale: George Leonard

Belatedly, I have just learnt of the death last month of George Leonard (1923-2010), writer, journalist, and aikidoka.  He took up aikido in middle age, a journey he wrote about movingly (see reference below), and ended up co-founding Aikido of Tamalpais.  His writings on life, the universe and everything have been very influential in my thinking about life, as I acknowledge here

The New York Times has an obit here and Quantum Tantra a tribute here.

Copy me, I’m on my way out

Cosma Shalizi at Three-Toed Sloth cannot understand why people desire original works of visual art rather than printed reproductions, especially when we’ve been buying printed books rather than manuscript codexes for centuries now.  He presents – and demolishes too quickly, I believe - some potential reasons for this.  I am very surprised by his view, but perhaps its the sheltered life I lead.

Thomas Jones A Wall in Naples

First, let me say as a computer scientist, that a map is not the territory.  It is easy to confuse a representation of some object with that object itself, and the people now singing the praises for e-books seem to be doing just that.   Au contraire, I believe that hard, physical books will continue to be purchased and kept yet for hundreds of years, and possibly many more years, because books are souvenirs of our experience of reading them.   The same is true of works of visual art.    If you have had some hand in the commissioning, the creation (for example, as subject of the artwork or as patron of the artist), or the selection and purchase of a work of art, you want the work of art itself, not a copy, to remind yourself of that experience.

Second, let me say as a former mathematician, that printed reproductions of artworks are projections onto 2 dimensions of 3-dimensional objects.  By definition, such projections will lose something.  If you think that what is lost thereby in visual art is unimportant, as Cosma seems to, then you’ve not been looking very closely at real paintings or drawings.  There are too many examples to recount, so let me just point to:  the brush-strokes in JMW Turner’s seascapes, which manifest and convey the torment of the scenes (and that of the painter); or the drip effects in Jackson Pollock’s action paintings, which likewise manifest and convey the energy of the creation process; or the careful, visible brushwork of the leaves and blades of grass in Pre-Raphaelite art or in the art of the Yangzhou painters of the early Qing Dynasty; or the brush-strokes in Chinese and Japanese calligraphy.   These effects are either invisible or can barely be seen in printed reproductions.  It is also worth noting that Chinese art has, for hundreds of years, supported “factory production” of 3-D paintings, using lesser-skilled artists to make approved copies of paintings by famous artists, usually under the direct, personal supervision of the famous artist him or herself; that these copies are purchased rather than printed reproductions indicates that the 3-D object has qualities perceived to be lacking in any 2-D print.

Third, let me say as a former statistician, that it seems to be easy for people familiar with Andrei Kolmogorov’s theory of complexity to imagine they have represented faithfully some object, when all they have captured is its surface form (its syntax).   As I have argued before, the canonical example used in discussions of algorithmic complexity is Kazimir Malevich’s painting Black Square, which is alleged to be easy to reproduce with an algorithm such as: 

Paint a pixel of black in each pixel throughout the square.

At best what this algorithm generates is a copy not of the 3-dimensional painting itself, but of a 2-dimensional projection of it.  But even were it to recreate the 3-D object, such an algorithm ignores the meaning of the painting and the historical context of its creation – in linguistic terms, its semantics (or its use-context-independent meaning) and its pragmatics (its use-context-dependent meaning).      Both these aspects are immensely important to understanding and appreciating the work, and for explaining why it appeared when it did and not before, and understanding its reception and influence.  As I noted before, one can just about imagine the 18th-century Welsh  landscape painter Thomas Jones eventually creating something similar to Black Square, since he painted contemplative, Zen-like depictions of seemingly-featureless Neapolitan walls (such as A Wall in Naples, pictured above), but no other artist before Malevich.

How is this relevant?  Well, once you’ve seen and admired Malevich’s painting, no printed reproduction would satisfy you for an instant. 

Finally, paintings – even when traditional, representational art – are best understood, not as representations of objects or scenes or feelings or indeed of anything at all, but as attempts at solutions to problems in painting.   Most solutions fail, so the artist abandons that attempt, and tries again.  In the meantime, the abandoned partial solution may provide pleasure and joy (or other responses) to those who view it, and to those who seek to emulate the methods of its painting which a careful study of it may disclose.

Mnemosyne

Ljova and the Kontraband have today released a video of their song, Mnemosyne, a setting of the poem by Joe Stickney which I posted here.  I mentioned listening to their superb album here.  

The evocative video uses footage from Ilya Khrjanovsky’s film 4, and is available here.




Maps and territories and knowledge

Seymour Papert, one of the pioneers of Artificial Intelligence, once wrote (1988, p. 3), “Artificial Intelligence should become the methodology for thinking about ways of knowing.”   I would add “and ways of acting”

Some time back, I wrote about the painting of spirit-dreamtime maps by Australian aboriginal communities as proof of their relationship to specific places:  Only people with traditional rights to the specific place would have the necessary dreamtime knowledge needed to make the painting, an argument whose compelling force has been recognized by Australian courts.  These paintings are a form of map, showing (some of) the spirit relationships of the specific place.  The argument they make is a very interesting one, along the lines of: 

What I am saying is true, by virtue of the mere fact that I am saying it, since only someone having the truth would be able to make such an utterance (ie, the painting).

Another example of this type of argument is given by Rory Stewart, in his account of his walk across Afghanistan.   Stewart does not carry a paper map of the country he is walking through, lest he be thought a foreign spy (p. 211).   Instead, he learns and memorizes a list of the villages and their headmen, in the order he plans to walk through them.  Like the aboriginal dreamtime paintings, mere knowledge of this list provides proof of his right to be in the area.  Like the paintings, the list is a type of map of the territory, a different way of knowing.  And also like the paintings, possession of this knowledge leads others, when they learn of the possession, to act differently towards the possessor.  Here’s Stewart on his map (p. 213):

It was less accurate the further you were from the speaker’s home . . .  But I was able to add details from villages along the way, till I could chant the stages from memory.

Day one:  Commandant Maududi in Badgah.  Day two:  Abdul Rauf Ghafuri in Daulatyar.  Day three:  Bushire Khan in Sang-izard.  Day four:  Mir Ali Hussein Beg of Katlish.  Day five: Haji Nasir-i-Yazdani Beg of Qala-eNau.  Day six:  Seyyed Kerbalahi of Siar Chisme . . .

I recited and followed this song-of-the-places-in-between as a map.  I chanted it even after I had left the villages, using the list as credentials.  Almost everyone recognized the names, even from a hundred kilometres away.  Being able to chant it made me half belong:  it reassured hosts who were not sure whether to take me in and it suggested to anyone who thought of attacking me that I was linked to powerful names. (page 213) 

Because AI is (or should be) about ways of knowing and doing in the world, it therefore has close links to the social sciences, particularly anthropology, and to the humanities.
