#47 background: Von Uexküll

On and off in the past months I have been working on a project on the invitation of ‘Utopisch Nest’, a collaboration between Municipal Museum De Lakenhal and music-theatre ensemble De Veenfabriek, both in Leiden. Every year they invite one or more artists to develop a dialogue- and research-oriented project that has a thematic connection with the exhibitions or the performances developed within these institutions. With this post and a few following ones, I want to catch up with the project I have been developing, starting with some of the backgrounds and moving into my own work, which I feel will be the beginning of something that will run over a much longer period of time.

I had an immediate click with the Utopia exhibition that has been in preparation for a long time and that has recently opened in Museum de Lakenhal. It is an exhibition that starts from the continuity between expressionism and constructivism and that also shows that in many ways the expressionists were perhaps more radical in their utopian thought than the constructivists. The radicality of the Utopia sketched in many of the works reminded me of another strand of thought in especially the Russian art of that period, within those artist’ circles where the differences between symbolism, expressionism and constructivism are not clear-cut at all. And that strand of thought linked it to some other long-running interests of mine that I have never had the time to explore more in depth in my own work.

The core inspiration behind #47 can be formulated as an investigation into the ‘maakbaarheid’ of our perception, ‘maakbaarheid’ being a perfect Dutch word for this occasion, and for which I would not know a suitable English equivalent. The word has clear utopian or modernist connotations since it is mostly used to refer to the remaking of society or the remaking of man. In English, the word ‘makeability’ would perhaps be the most literal translation, or, when talking about perception, ‘plasticity’ would be an obvious choice, but both of those words lack that Utopian ring.

The sources of inspiration of this project can be divided like so:
- the research of Jakob von Uexküll into the sensory worlds of animals,
- studies of the senses of animals, especially senses that are very different from ours,
- the ideas of certain artists about the role artist have in shaping the perceptual abilities of their audience, most articulate in the ideas on ‘extended vision’ developed by Michail Matyushin and his students.
- research into sensory substitution and sensory augmentation, and especially the work of Paul Bach-y-Rita.

First about Jakob von Uexküll, since I’ve been interested in him for the longest time and because I believe his ideas are the most fundamental to this project.

When making my film #11, around 15 years ago, I found out about Uexküll via a mention of him in Stephen Kern’s book ‘The Culture of Time and Space 1880 - 1918′. Kern talks about him as one of the thinkers who contributed to the idea that space and time are not absolute, but relative to cultures, to individuals even, or in the case of Uexkull to species.

uexkull_snail.jpg

A lot of what I find interesting about Von Uexkull is demonstrated in his discussion of one of my favourite images of a scientific experiment ever: a snail experiment Von Uexküll refers to in his ‘Streifzuge durch die Umwelten von Tieren und Menschen’ from 1933, unfortunately without mentioning the name of the ‘young experimenter’ whose work this was. In Von Uexküll’s words:

“Eine Weinbergschnecke wird auf einen Gummibal gesetzt, der, vom Wasser getragen, reibungslos unter ihr weggleiten kann. Die Schale der Schnecke wird durch eine Klammer festgehalten. Dadurch ist die Schnecke in ihren Kriechbewegungen ungestort und bleibt doch an der gleichen Stelle. Bringt man nun ein Stockchen an ihre Sohle heran, so kriecht die Schnecke auf dasselbe hinauf. Erteilt man mit dem Stockchen der Schnecke 1-3 Schlage in der Sekunde, so wendet sie sich ab. Werden aber die Schlage viermal und mehr in der Sekunde wiederholt, so beginnt sie das Stabchen zu besteigen. In der Umwelt der Schnecke ist ein Stab, der viermal in der Sekunde hin und her schwingt, bereits zu einem ruhenden geworden.”

in English:

“A snail is put on a rubber ball that can move under it without friction, since it is floating on water. The snail’s shell is being held by a clamp. In this way the snail is free in its crawling motions, but will stay on the same spot. When we put a little stick in contact with its foot, the snail will crawl on it. When we hit the snail 1-3 times a second with the little stick, the snail will turn away. But if we repeat the contact four times or more per second, it will start to climb the little stick. In the ‘Umwelt’ of the snail, a stick that moves to and fro at a speed of four times per second has already become a stick at rest.”

If I try to formulate what I see as the essence of the ideas of Von Uexküll it would be that the world of every animal only consists of those things in the environment it can interact with. Von Uexküll explains this by giving examples of species with simple worlds, such as ticks, some single cell organisms, and jellyfish. In his ‘Umwelt und Innenwelt der Tiere’, from 1909, he for instance explains that the jellyfish can basically do only one thing, which is to contract, a motion that both propels it and brings water with food into its ’stomach’. And this motion is triggered by nerve cells on the edge of the jellyfish, cells that trigger the next contraction as soon as the one and only muscle has fully relaxed after the previous contraction.

“Wenn man vom Bord des Schiffes aus die schimmernde Flaeche des blauen Meeres ueberschaut und darin die stummen Glocken der Medusen einherschweben sieht in zahllosen Scharen wie wundervolle Blumen eines Zaubergartens, so Ueberkommt uns unwillkuerlich das Gefuehl des Neides. In all dieser Farbenpracht einherschweben zu duerfen, frei und unbekuemmert, von den klingenden Wogen getragen, durch den strahlenden Tag und die glaenzenden Mondnacht, muss ein herrliches Los sein. Aber die Meduse vernimmt von alledem nichts. Die ganze Welt, die uns umgibt, ist ihr verschlossen. Das einzige, was ihr Innenleben ausfuellt, ist die gleichmassige Erregung, die, von ihr selbst erzeugt, immer im gleichen Wechsel in ihrem Nervensystem entsteht und vergeht.”

in English:

“When, from the deck of a ship, one looks out over the shimmering surface of the blue sea and sees the silent bells of the jellyfish float in innumerable flocks, like wonderful flowers of a magic garden, we are inadvertently struck by a feeling of envy. To be able to float in all this colourful splendour, free and light-hearted, rocked by the resounding waves, through radiant day as well as glistening moonlit night, must be a delightful fate. But the jellyfish doesn’t sense any of this. The whole world that surrounds us, is closed to it. The only thing that fills its inner life, is the steady agitation, which, triggered by the animal itself, always arises and passes in the same sequence in its nervous system.”

uexkull_funkreis.jpg

In the vocabulary of Von Uexküll, the jellyfish has an exceptionally simple world, consisting as it does of one loop that hardly includes anything of its environment. For animals with a richer world, that world is the sum of a number of ‘Functionskreise’ (’Functional loops’). In each of those, one ‘Merkmaltraeger’ (’sign’) triggers a behaviour that is aimed at eliminating its triggering sign, so the loop goes from sign to sense organ to effector organ that makes a change in the environment and eliminates the sign in some way or other. Simple organisms have two or three of such loops, complicated organisms like humans have many many of them, and two species share those parts of their world where these loops overlap or intersect. We humans have a relatively rich world because we have many of these loops, with many signs in our environment that can be triggers for action of some sort.

I find this image of what our world is very precise and productive, and very intriguing too, since it immediately raises the question whether we can have access to those worlds that different from ours. Interesing about this is that these other worlds are parallel, but in a very concrete sense; true extra dimensions without any need of vague or esoterical mumbo-jumbo. And in some sense much of the work of Von Uexküll can be seen as an attempt to develop a vocabulary to understand more of the inner logic of the worlds of different species, while trying to stay out of the trap of presupposing our human world as the true one.

A good example of one of the words in his vocabulary is the notion of ‘Die Fernste Ebene’ (’The Farthest Plane’), which embodies the limit of the physical world of each species. It is the distance beyond which we can not act:

“the space peculiar to each animal, wherever that animal may be, can be compared to a soap bubble which completely surrounds the creature at a greater or lesser distance. The extended soap bubble constitutes the limit of what is finite for the animal, and therewith the limit of its world; what lies behind that is hidden in infinity.”

The reason I find this such a powerful image is that it is very tangible: it is our bubble that makes us see the sky as a curved dome; there is nothing that is really curved out there.

Von Uexküll had a turbulent biography; born in 1864 he was a Baron in the german-speaking nobility in Estonia, studied in (amongst many other places) the lab of Etienne-Jules Marey, lost his family fortune because of the Russian revolution, finally got offered a position in Hamburg in 1924 and built up his Institut für Umweltforschung there until 1940, when he retired to Capri, 76 years old.

His ideas have directly influenced philosophers like Heidegger, Merleau-Ponty, Von Glasersfeld, Deleuze and Agamben; it was in fact in one of Agamben’s books that I first read that those aspects of Heidegger’s thought I can most relate to, are in fact heavily inspired by the work of Von Uexküll (a great, recent study of some of these influences is the book by Bret Buchanan). Apart from this, his work is often cited as a precursor of cybernetics and radical constructivism and I can see many similarities between his ‘Funktionskreis’ and the strange loops that are so pervasive in the ideas around Autopoiesis by Humberto Maturana and Francisco Varela. Also the work of Von Uexküll is a crucial precursor of the ‘New Artificial Intelligence’ and the work on situated robotics by people like Rodney Brooks. All very interesting stuff, interconnected by many strands, a lot of which started in the work of Von Uexküll, but still, in my opinion, few of these authors reach the clarity and radicality of the writing of this man himself.

And to bring these ideas back to my project, one way to formulate the research questions behind it would be in terms of the ‘Funktionskreis’ of Von Uexküll:

can we extend our world by making new feedback loops through the environment ?
can we make new ‘Funktionskreise’ by building devices that can act as new senses ?

premiere film #43

frame02857sm450w.jpg

Tomorrow, at the Kontraste Festival in Krems (Austria), will be the premiere of a film I made before the summer, which I decided to call ‘#43′. It is part of the Vertical Cinema project initiated by the nice people of Sonic Acts and it is one of ten short films they commissioned in a unique format: Vertical Cinemascope (the same as normal Cinemascope, but in portrait/monolith mode, not landscape mode).

frame02857detail.jpgdetail of frame

The film henceforth known as ‘#43′ is part of a long-running exploration of algorithms that are based on a combination of propagation and local interactions. Originally triggered by an encounter with simulations of how nerve impulses organise themselves into oscillations in tissues like heart muscle, for example, the project has since expanded to include an interest in the more general emergence of patterns in time and space out of homogenous starting conditions. These explorations are inspired by a set of ideas from biology and mathematics that first came to prominence during the development of cybernetics in the 1950s and 1960s, and that have since then evolved into more recent manifestations such as catastrophe theory, complexity theory and artificial life.

In my work, this has led to live visual work with improvised and composed music as well as moving images in various fixed and mostly non-standard formats. “#43.1, Lichenometry”, was my debut as live visuals performer outside of dance and theatre projects and has been a collaboration with different live music improvisers over the past two years, #43.2 was part of the ‘Palmtop theatre’ project by V2, #43.3 was the visual companion to the musical composition ‘Wavespace’ by Yannis Kyriakides for the ASKO Ensemble, #43.4 was a one minute video made as a commision for the ‘Modern Times’ project by Stichting Cinema Zuid in collaboration with the One Minutes and #43.5 is a new piece still in continued development for a spherical projection system as part of the ‘Sphaerae’ project of Cocky Eek in collaboration with Synergetica Lab and the ArtScience Interfaculty. So that would make “#43.7″ the logical title for this film, except that it feels as a kind of temporary end point for my experiments with this particular class of algorithms.

An aspect of this film that is perhaps of mainly personal interest is that it has the first soundtrack for one my own films I did myself since my very first film #2, almost exactly 20 years ago.

So here goes the blurb:

Joost Rekveld
‘#43′
35mm vertical scope, 11 minutes, 2013.

The images in film #43 are generated by systems in which the pixels are agents that are, in some respects, comparable to cells in an organism. These systems are bumped into motion by disruptions that cause a difference between some pixels and their neighbours. Such an edge of difference becomes the seed for processes of decay and growth, an imbalance that embodies a store of energy for the system as a whole, similar to an electrical potential. Under some circumstances the cells in the system feed each other so that oscillations or other kinds of order are produced spontaneously, sometimes stable in themselves, sometimes feeding on noise to stay active.

The composition of this film was influenced by the work of logician G. Spencer Brown, who wrote his ‘Laws of Form’ in 1969. The book is a wonderful account of a new kind of logic that lends itself especially well to describe the seeming paradoxes of self-reference. The empty pages on which the book is written form the beginning, the end, as well as an integral part of the argument.

“What I try to show, in the final chapter, is the fact that we really knew all along that the two axioms by which we set our course were mutually permissive and agreeable. At a certain stage in the argument, we somehow cleverly obscured this knowledge from ourselves, in order that we might then navigate ourselves through a journey of rediscovery, consisting in a series of justifications and proofs with the purpose of again rendering, to ourselves, irrefutable evidence of what we already knew.
Coming across it thus again, in the light of what we had to do to render it acceptable, we see that our journey was, in its
preconception, unnecessary, although its formal course, once we had set out upon it, was inevitable.”

G.Spencer Brown , ‘Laws of Form’, 1969.

art as injunction ?

Thoughtprovoking remarks taken from the notes to chapter 2 of ‘Laws of Form‘ by G. Spencer Brown:

“It may be helpful at this stage to realize that the primary form of mathematical communication is not description, but injunc­tion. In this respect it is comparable with practical art forms like cookery, in which the taste of a cake, although literally indescribable, can be conveyed to a reader in the form of a set of injunctions called a recipe. Music is a similar art form, the composer does not even attempt to describe the set of sounds he has in mind, much less the set of feelings occasioned through them, but writes down a set of commands which, if they are obeyed by the reader, can result in a reproduction, to the reader, of the composer’s original experience.

Where Wittgenstein says [4, proposition 7]
‘whereof one cannot speak,
thereof one must be silent’

he seems to be considering descriptive speech only. He notes elsewhere that the mathematician, descriptively speaking, says nothing. The same may be said of the composer, who, if he were to attempt a description (i.e. a limitation) of the set of ecstasies apparent through (i.e. unlimited by) his composition, would fail miserably and necessarily. But neither the composer nor the mathematician must, for this reason, be silent.

In his introduction to the Tractatus, Russell expresses what thus seems to be a justifiable doubt in respect of the rightness of Wittgenstein’s last proposition when he says [p 22]

‘what causes hesitation is the fact that, after all, Mr Witt­genstein manages to say a good deal about what cannot be said, thus suggesting to the sceptical reader that possibly there may be some loophole through a hierarchy of languages, or by some other exit.’

The exit, as we have seen it here, is evident in the injunctive faculty of language.

Even natural science appears to be more dependent upon injunction than we are usually prepared to admit. The pro­fessional initiation of the man of science consists not so much in reading the proper textbooks, as in obeying injunctions such as ‘look down that microscope’. But it is not out of order for men of science, having looked down the microscope, now to describe to each other, and to discuss amongst themselves, what they have seen, and to write papers and textbooks describ­ing it. Similarly, it is not out of order for mathematicians, each having obeyed a given set of injunctions, to describe to each other, and to discuss amongst themselves, what they have seen, and to write papers and textbooks describing it. But in each case, the description is dependent upon, and secondary to, the set of injunctions having been obeyed first.

When we attempt to realize a piece of music composed by another person, we do so by illustrating, to ourselves, with a musical instrument of some kind, the composer’s commands. Similarly, if we are to realize a piece of mathematics, we must find a way of illustrating, to ourselves, the commands of the mathematician. The normal way to do this is with some kind of scorer and a flat scorable surface, for example a finger and a tide-flattened stretch of sand, or a pencil and a piece of paper.”

a polyfusion of media

Great poster of an interesting event in 1974. I did not realize Bill Etra did live performances too with his Rutt/Etra video synthesizer.

astral_projections.jpg

Some more information from ‘The Monroe Doctrine’, a local paper a few days before:

“‘Polyfusion,’ an hour long blending of the Central Maine Power Music Company and the video artistry of the Survival Arts Media and Bill Etra, comes to the Strasenburgh Planetarium dome September 20 and 21. Each night the Survival Arts Media will combine live music and video images with a sophisticated video-processing system. Low light level video cameras will feed images of the musical performance into a Rutt/Etra Video Synthesizer.
The black and white images within the synthesizer will have pure colors added, then be modified by artistically sorting them to take on new texture and form. Images can also be combined within the synthesizer, and the music and video can be used to modify each other. The resulting video collage will be displayed in two giant, color images from General Electric video “Light Gate” video projectors.”

and: “According to Polyfusion coordinator Howie Gutstadt, the theme of the video-music show will be Astral Projection, a concept that expresses individual’s astral body or consciousness.
Gutstadt says that, “It is rare that this much sophisticated video equipment will be used together. The Planetarium is a possible model for the environmental theater that media artists will use in the future.”
