Identity Bureau: Legal Identity for Trees

Start: July 26, 2012, 10 a.m.
End: July 27, 2012, 6 p.m.


Description

On 26th and 27th July FoAM and Z33 co-organise a two-day workshop lead by Heath Bunting and An Mertens and linked to Heath's work Identity4You,
presented at Mind the System, Find the Gap - the summer exhibition at Z33.

During this workshop you learn how you can create a legal identity for trees.
With your guardianship they will be able to gain a voice in society, first ficticiously, but who knows, maybe in the long run they will be able to vote legally.
Identity Bureau questions the notion of personality by showing how an identity is constructed largely by material issues.

vegetal + alchemy?

Amici,

A note for the advanced grad seminar on alchemy.

Thanks to Natasha Myers for pointing out Michael Marder's work, especially: Plant-Thinking: A Philosophy of Vegetal Life (New York: Columbia University Press, forthcoming in 2012)

Here are extracts from essays.   Shall we throw this on the possibles list for a Fall?

Vegetal anti-metaphysics: Learning from plants
Michael Marder
Cont Philos Rev (2011) 44:469–489

Alluding to the heteronomy of plants, Hegel views the seed as ‘‘an indifferent
thing’’: ‘‘In the grain of seed [Samenkorn] the plant appears as a simple, immediate
unity of the self and the genus. Thus, the seed, on account of the immediacy of its
individuality, is an indifferent thing; it falls into the earth, which is for it the
universal power.’’59 We might add that the seed, entrusted to the randomness of
chance and the externality of its medium (the earth), maintains an ineliminable
possibility of being wasted, spread, or spent for nothing, the possibility that is
indicative of its freedom. But before the fall of the Hegelian seed into the earth, the
plant’s lack of individuality is cast in terms of the ‘‘simple, immediate unity of the
self and the genus.’’ Given that the seed’s self, relegated to the universality of the
element and of light, is always external to itself, this unity is, at the same time, a
disunity, a double indifference of the light and the earth to the seeds they nourish
and of the seeds to their self-preservation, their own fate, since they have no
intimate self to preserve. With this observation, we have stepped over the threshold
of Derridian dissemination, where the breakdown of the unity and identity of the
seed spells out the multiplicity it shelters even in the singular form: ‘‘…numerical
multiplicity does not sneak up like a death threat upon a germ cell previously one
with itself. On the contrary, it serves as a path-breaker for ‘the’ seed, which
therefore produces (itself) and advances only in the plural. It is a singular plural,
which no single origin will have preceded.’’60 In its singularity, the seed is already a
legion: whether spilled or spread, it is both one and many. Denoting animal and
vegetal modes of reproduction alike, it is, nevertheless, uniquely appropriate to each
animal and to each plant. The seed’s singular plurality, adopted by Jean-Luc Nancy
in his own thinking of community,61 thus, sketches out a model of justice
understood as the aporetic confluence of indifferent universality (‘‘seed’’ defying the
boundaries between species and even kingdoms) and attention to singularity (its
appropriateness to each).
The figure of the plant that, like a weed, incarnates everything the metaphysical
tradition deems to be improper, superficial, inessential, purely exterior, turns into
the prototype of a post-metaphysical being. Plants are the weeds of metaphysics:
devalued, unwanted in its carefully cultivated garden, yet growing in-between the
classical metaphysical categories of the thing, the animal, and the human—for, the
place of the weed is, precisely, in-between62—and quietly gaining the upper hand
over that which is cherished, tamed, and ‘‘useful.’’ Despite all the abuses to which
they are subjected, the weeds and, more generally, the plants will outlive
metaphysics.

Plant-Soul: The Elusive Meanings of  Vegetative Life
Michael Marder
Environmental Philosophy 8 (1): 83–99, 2011.

From nutrition, through assimilation and appropriation of the
other to the same, to the will to power: the chain of reductions to the
fundamental capacity of plant-soul winds on in an infinite regress to the
evanescent first principle, rendering every new term more metaphysical
than the preceding one. Nietzsche explains the latest and the most
vital link in the conceptual chain—the will to power—as a desire for
the accumulation of force, in the service of which the other has been
put: “The will to accumulate force is special to the phenomena of life,
to nourishment, procreation, inheritance—to society, state, custom,
authority” (1968, 367). The exuberance of vegetative life, its proliferation
is, thereby, metaphysically harnessed for a particular end, for the will to
power, desiring the accumulation of more power (more life). Nietzsche
does not entertain the hypothesis that the phenomena of life and,
among these, the vitality of plants often preclude the hoarding of power
because these living beings, like all the others, are the passages, outlets,
or media for the other, and because, more precisely, they are but the
intersections in the exchange of gases, or Fichtean “central points” in the
process of chemical attraction and repulsion. For, what if plant-soul and
plant-thinking let the other pass through them without detracting from
its alterity? What if they grow so as to play this role more effectively, to
welcome the other better? And what if all this is accomplished thanks to
the essential incompletion of linear growth that does not return to itself
but is, from the very outset, other to itself? What if, finally, this inherent
respect for alterity spelled out a key meaning of vegetative life?

RESIST LIKE A PLANT! ON THE VEGETABLE LIFE OF POLITICAL MOVEMENTS
Michael Marder
Peace Studies Journal, Vol. 5,  Issue 1, January 2012

Abstract 
This brief article is an initial attempt at conceptualizing the idea of political movement not on the basis of the traditional animal model but, rather, following the lessons drawn from vegetal life. I argue that the spatial politics of the Occupy movement largely conforms to the unique ontology of plants and point toward the possibility of a plant-human republic emerging from it.

Dear Adam, Liza, Magda, JoDee, Omar, Nikolaos,

Let me welcome you as graduate students and research fellows with whom it'd be a pleasure to seminar this coming year.

Prompted by Nikolaos and Adam's queries: although this year I'm not offering a grad course, I'm willing to do a "pro-seminar" providing orientation related to the TML's creative research, if a bunch of grads are interested.   In the past, grads have done this as  Independent Studies with me.

Some possible themes are outlined in these course websites:

SIP 825 / 637: Seminar Critical Studies of Media Arts and Sciences

or

HUM 888: Doctoral Seminar in Interdisciplinary Studies I: Critical Studies of Media Arts and Sciences: Subjectification, Process, and Performance

Just so you know, some folks around the TML are also interested in more specialized or advanced seminars, for example one on alchemy as an alternative to capitalist sorcery (as characterized by Stengers and Pignarre), and another on temporal textures.  The latter may be coupled with some experiments with movement  in responsive environments and responsive realtime media.

We should probably send word to Humanities PhD program bc I knew there are some great PhD's there.

Apologies, for not responding earlier to some of your inquiries -- this past few months have been enormously trying with personal responsibilities and professional obligations.  But I do look forward to seeing you this fall if not much sooner! 

Warm regards,
Xin Wei

PLSS-Annex update!

Hello All, 

I'm super stoked to be finally getting the greenhouse documentation up here and to be moving forward this PLSS this winter!
Now that the structure is up and ready to go, we're looking at organizing a few things for the next two months:

1) We'll be planting a new crop of herbs very shortly :) I've ordered an fantastic array of medicinal herbs from http://www.saltspringseeds.com/

Anise (Pimpinella anisum)

Echinacea tennesseensis

Sweet Fennel (Foeniculum vulgare dulce)

Wood Betony (Stachys officinalis)

Arnica (Arnica montana)

Fenugreek (Trigonella foenum-graecum)

Marshmallow (Althea officianalis)

Spilanthes (Acmella oleracea)

St. John's Wort (Hypericum perforatum)

Motherwort (Leonurus cardiaca)

Greek Mountain Tea (Sideritis syriaca)

Evening Primrose (Oenothera biennis)

Rama Tulsi (Holy) Basil (Ocimum sanctum)


The range of health benefits from consumption of these plants is really fantastic (I'm pretty into the immune system boosters for this winter season!) I will be composing a short info guide for these seeds and the plants' health benefits that we can post online as well as keep in the lab. Also, this has gotten me thinking about the idea of the apothecary/pharmacy...could be a new branch of thinking for PLSS.

2) Gearing up for an open-house/skill share to reach out to the rest of the Concordia student body and share the design plans we've come up with for the portable greenhouse! This will also involve hosting a 'tea' from our 1st harvest of herbs.

3) Constructing a simple hydroponic system for the greenhouse. I've found some great instructions here: http://www.hydroponics-simplified.com/support-files/mini-lettuce-raft-pdf.pdf I'm going to build two of these - one for the TML and one for the portable greenhouse.

4) Looking into mycology! It would be wonderful to get this started. I know Tyer is enthusiastic about this idea and so am I. I found out there's actually a legit mycology store right here in Montreal: http://www.mycoboutique.ca/en/
I hear they have everything one needs to cultivate mushrooms so I'm gonna check it out.

That's all for now! Looking forward to a little more green and a little less slush/ice/whathaveyou ;)

the mundane

I realized that my email this morning may have been misinterpreted because I wrote it so hastily.  I think that the plant work, and Zoe and Katie's work in particular is part of the most profound evolution of the TML's research direction since I started the atelier lab 10 years ago.    As I said to people in a seemingly different line of work -- the lighting group (Morgan Sutherland, Harry Smoak, Navid Navab ... - it is  crucial that we do things step by step, that in fact that we start with the humblest, the most modest, and the most mundane applications of our unusual technical and technological prowess.     The mundane, the everyday is in fact the very heart of  what I am hoping will be the application of the Topological Media Lab's most sophisticated experimental art and philosophy.   As with the use of our Ozone media system to inflect the household halogen lamps, so with the hosting of "ordinary" plants in the lab...   

This work must be more than a few brave words or occasions, it must be the tending of living things week after week by enough of us.    It should be us, not some work-for-hire gardener paid to tend some ornamental plants.  I am vitally interested in experimenting with the sociotechnical ensembles of the TML to find out, because I think our programmers' and media art students' very inattention is itself a microcosmic symptom of the catastrophe that is Technological Progress.   I'm happy to be part of this as much as I can to help launch this and recruit people -- current and future TML people -- with you and Katie.   

I started this conversation with Flower Lunn <floramarialuna@gmail.com> 3 years ago, a wonderfully thoughtful, gentle and determined artist who studied with me as a wise "undergrad" and did her MFA in Fibres.   And later with Josee-Anne Drolet <joseeanne@gmail.com>, Elena Frantova <frantovka@gmail.com> and  Timothy Sutton <timsutton@fastmail.fm>.   It is a risky path because it can make the lab look unflashy, even naive.  It may even bring the lab down in institutional power, which could mean its closure.  But this is the heart of the ethico-asthetic experiment that is the lab itself as a socio-technical organism.

I think that media artists who are in a hurry to make machines sit up and make 3D this or that in OpenGL have a lot to learn from working with earth and vegetal life.   The challenge is how to blend the attention, then the habits of everyday work, across the artists and philosophers hosted here: those who code Max/MSP/Jitter, those who solder, those who handle paper or fibres, those who work earth, and those who work words,...  Laura Boyd-Clowes <l.boyd.clowes@gmail.com> is a word and earth worker, who I value as much as the Ozone creators.   She would be the natural student leader of the philosophical thread intertwined with the living sculpture work.    But she may be too busy to do much this year.  Nonetheless I would invite Laura to come continue the discussions from Spinoza, through Bateson and Guattari in concert with the gardeners and programmers among us.

I'm sorry that now I am (we are all) stretched thin.   But in the end that should not matter because the initiative, the power, authentically can only come from you and friends.     I do hope to be more present in this aspect together with the domestic phenomenological experiments after Dec 3.   I very much appreciate Zoe's careful attention and Zoe and Katie's principled thought behind the work, which will twin together with Jane Tingley and Michal Seta's exquisite work.  I find delightful, for example, the taut lines Zoe pinned neatly across the tops of the earthen bins to train our seedlings, some of whom have sprouted from the sixth generation of morning glories that Josee-Anne tended with so much care and hope, seeded from Flower Lunn circa Remedios Terrarium.

This is part of the story that I tell about the TML when I talk about the future.  We will want to share this also with for example, Lina Dib <linadib@rice.edu>, the anthropologist with whom I am composing an invitation to the TML during the Anthropological Association of America conference Nov 16 - 20 here in Montreal.  

The problem we face as an atelier is that those who are students are fragmented into the classes and the hundreds of distractions that students must entertain.   And those who work or have families to tend have insufficient the energy or time perhaps to tend yet another space full of lives.   But caring for plants is a mark of integrity and depth in an institutional and social field still hurting with postmodernity's flatness and frictionlessness.   I would like to learn how we may collectively conduct philosophically informed creative research over the long term in a way that accommodates students as well as working people, not just those few who happen to be lucky or political enough to be funded by some grant to do just this at the TML.    This may be impossible, but as Badiou may have argued 2000 years after Zhuangzi and Laozi, paradox can be generative.  The plant project is part of this sociotechnical / institutional experiment, and its very mundaneness is our risk, our tactic, and our method.

So, thank you, and let's proceed.

Dear Vincent, Adrian,

Thanks a lot for the intros!

The best would be to talk directly with the PLSS vegetal research group.  This year led by Zoe Yuristy.   Last year's Spinoza - Bateson - Guattari reading group was led by Laura Boyd-Clowes.  Now we are doing very very mundane beginning -- just to plant seedlings in fresh dirt, then get humidity sensors to semi-automate the watering system.    Our philosophy seminar is suspended, although that is the most promising in terms of ground-breaking research, we simply are too busy to push that forward for now.  Maybe with your intervention, we can advance the philosophical investigation in a rigorous way!

Natasha Myers @ York University (Toronto) brings together her training as a botanist, and dance, as well as her wok in science & technology studies.    There are fascinating works with plant chemical signals, chemical memory, plant movement + human movement, etc..  She should be part of the more research oriented conversation.

Let me suggest that Adrian make the translations :)  I'll do that too after my deadlines ease up a bit Dec 2.

Well, hi y'all!  Great introduction from Adrian!
Here's a one-pager which summarises the second subject Adrian mentions:  <The selective advantage.doc>.  If the idea has a fault, it's that the model is so strong that it explains too much!  I'm collecting press cuttings, quotations, etc, which is the only way I know to accumulate information in this sort of area.  My ideal would be to interview some practising artists, but I  fancy I need a bit more credibility before I can persuade someone to give me the cash to travel.  Ideally I would interview a couple of dozen of the current top artists (all categories) in the world - maybe more.  If any of you know someone of sufficient standing and compliance who would agree to do it for free, I'd love to run them through the system!  And your comments, too.  At present I'm putting the data into an ontology which is my current way of filing and assembling data.  You can have a copy if you are interested.

The first subject which Adrian mentions requires a bit more background since it's not published and needs some understanding of botany and engineering.  The bending stiffness of a rod depends on the diameter of the rod (or, more generally, the shape and size of its cross section) and the material it's made of.  A small-section rod made of stiff material will bend to the same amount as a large-section rod made of less stiff material.  We were working on tobacco plants which had one of the three pathways producing lignin (= 'wood') downgraded.  In the greenhouse (a wind-free environment) they were trained up pieces of string, and looked exactly the same as the controls which had full lignification.  But the ones with reduced lignin were more floppy (lower bending stiffness).  However, if a plant is stimulated mechanically it tens to stiffen up (thigmomorphogenesis) by changing its dimensions.  We tried this with both normal and downgraded plants and found that they grew differently such that the stem of the more floppy one grew bigger in diameter than the control plant, resulting on both plants having the same bending stiffness.  In other words, they both ended up with the same mechanical properties.  I adduced this to mean that the plant had a 'concept' of how stiff it should be, correcting for and short-comings in the material it's made of,and therefore has a self-image, or is conscious!  I have to admit that this interpretation of a well-known phenomenon was created in order to wrong-foot those who believe that only man is capable of consciousness and self-knowledge, but it also means that, perhaps, one should think a bit more clearly about what consciousness means and how to define it!
The basic data are published and is kosher, but the above argument is not published.

Comments welcome!

I would like to introduce you all to Julien Vincent who I met at the the Fiber Society Conference last week.

http://www.ted.com/profiles/43903
http://www.bath.ac.uk/mech-eng/biomimetics/people.html

Julien's work and his interesting peridisciplinary thinking intersects themes of the PLSS project and the TML in general.
Our conversations ventured far and wide but a couple of relevance are: 

1) An ingenious interpretation of a specific plant biomechanics experimental as evidence of plant self identity. I heard about this post-Guiness so perhaps
Julian can refer us to a paper for the details. As you all know I am just an interest tourist when it comes to biology but I keep getting a lot of Julian's field. For example
I used the locomotion of wild wheat awns in a recent paper as an example of entrainment. I suspect there is much in the mechanical aspects of plants to stimulate
discussion of agency at the boundaries of the living/and non living.


2) The following idea of his:
"The selective advantage of art. Art (all varieties) is a safe method of allowing people to rehearse alternative futures. The engagement is to guess what will happen next, which relies on pattern recognition (well known) but demands projection of the pattern into the future (commonly not appreciated). The person who 'knows' what will happen next is the most likely to survive. Therefore art, apparently totally useless in terms of evolutionary advantage and so strangely persistent, appears to have a central role in our survival mechanisms."

As you can imagine this second point has received insensitive resistance from the usual places. Rather than add weight to the obvious critiques I would like us to engage in conversation with Julian
to deepen, broaden and sharpen  this insight of his.

I referred Julian to Lucy Suchman's work on situated action.

Simondon is also  relevant because he uses the language of evolution in considering the evolution of the technical object. 
Heavy-hitting scientists who have considered evolution and social patterning include Varela, 
and for music we have Attali's argument (in Noise) that society tests new technologies first  in music and sound because 
these modailities have fewer material constraints. Andrew Pickering has started to look at art but his early work on this was not met very sympathetically in the DART503 seminar last year.

I am sure some of you biologist/philosophers and artist/biologists have some more useful suggestions for Julian.
Please share them.
Thanks.


p.s.
Julian knows the RepRap inventor Adrian Bowyer so it might be interesting to share your experience on how the TML plants entrained you to build them a RepRap.

Hi Michal, Hi Morgan,

This is all great -- can't wait ti see the data come trickling into Ozone soon!     But let's design for a world in which we have dense set of sensors, where dense means approximately  continuous in space, time, as well as data-space.   Practically speaking, this means on the order of video density, i.e. tens of millions of channels per unit time.   In the face of such density, it makes sense to use a minimax design tactic:  minimum bandwidth needed to maximally intercalate vegetal / soil activity with social activity.

Another design tactic I would us to try in most of our sensor work is to use a push model instead of regular polling (a pull model).  This means I'd like the sensor to emit data when there is a change above a delta.   Ideally that delta should be tunable by an application programmer.   This means the sensor data should arrive from the analog world with irregular intervals of time.    (Thanks to Joel Ryan and his work with gestural musical sensing.)

Tim and Flower's timelapse data show us that our fastest growing plants -- the morning glories -- had a "frequency"  of about one macroscopic (human legible) cycle of creeper per hour.   (Ask Natasha Myers @ York for a technical term :)    I don't know what the frequency should be, but I would like to work with the lowest possible frequency that we can.

The research challenge is in fact : How can we intercalate the slow rhythms of sidereal and vegetal activity (hour) with human rhythms (second) in a way that is legible to us?

This goes to the heart of the fact most "environmental" sensor art is boring or has the same affect as noise.   Rather than fetishize the boring or noise as aesthetics, let's see what we can do with streams of sparse, irregular sensor data.

Probably not worth the time/headache. Should be sufficient to put a sticker with the send/receive IP's on the box and maybe make an API over ethernet where you can change the outbound IP's if it's trivial. 

Not being a plant expert, I don't know what data rate makes sense, once an hour?  I can make it configurable.

At least ten time per second or so, and do make it tunable. No reason to cut bandwidth for no reason – we believe in keeping as much data as possible for as 'long' as it's practical (just don't send at max speed / w/o delays!)

Great, then you're set.

UDP is preferred.

Great! Thank you. This is a nice surprise for me – I assumed I was going to have to do this in September/October.

What I meant to say is that it might be easier to roll your own OSC "library" since making a basic OSC message without timestamps, bundles and wildcards does not require a library to do – it's just a int/float with a string identifier and type tag appended. Like:

oscPacket = sprintf("/path/to, i, %c", number);
ethernet.udpSend(oscPacket);

I referred you to OSCuino because the functions sendOSCfloats and sendOSCthings will show you how to construct a proper OSC message w/ AVR C. So if the ethernet library is stable, no need to bother with a half-working OSC library on top of it just to do some string formatting!

For future maintenance, I'm of the opinion the things should be kept simple in terms of implementation so that people in the future can figure them out easily rather than simple of interface (which more often then not means complex implementation).

I had a look at the Arduino ethernet library and to my surprise it doesn't support UDP (only TCP). Somebody has written here a modified version that uses UDP: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1231346812 (not sure if you found this already). You can give it a try, but some people have compile errors. The other option would be to find a TCP object fro Pd. Or rather than using Pd, you could write a little Python/Ruby/C script that receives the data and broadcasts it on localhost for Pd or Max to pick up.

All that said, if you can get the OSC library working, then by all means use it. Just trying to make suggestions to make your life easier!

Thanks Michal.
