The Act as "Bartleby" Inactivity
Quote from Living in the End Times, pp. 400-401:
"rather than actively resisting power, the Bartleby gesture of 'preferring not to' suspends the subject's libidinal investment in it -- the subject stops dreaming about power. To put it in mockingly Stalinist terms, emancipatory struggle begins with the ruthless work of self-censorship and auto-critique -- not of reality, but of one's own dreams.
The best way to grasp the core of the obsessive attitude is through the notion of false activity: you think you are active, but your true position, as embodied in the fetish, is passive. Do we not encounter something akin to this false activity in the typical strategy of the obsessive neurotic, who becomes frantically active in order to prevent the real thing from happening (in a tense group situation, the obsessive talks continually, cracks jokes, etc., in order to ward off that awkward moment of silence in which the underlying tension would become unbearable)? The 'Bartleby act' is violent precisely insofar as it entails refusing this obsessive activity -- in it, not only do violence and non-violence overlap (non-violence appears as the highest violence), so too do act and inactivity (here the most radical act is to do nothing).
[...]
If theology is again emerging as a point of reference for radical politics, it is so not by way of supplying a divine 'big Other' who would guarantee the final success of our endeavors, but, on the contrary,
as a token of our radical freedom in having no big Other to rely on."

Capitalism as (inherently-ethical) Drive?
Slavoj Zizek: Capitalism is . . . and this, almost
I’m tempted to say is what is great about it, although I’m very critical of it
. . . Capitalism is more an ethical/religious category for me. It’s
not true when people attack capitalists as egotists. “They don't
care.” No! An ideal capitalist is someone who is ready,
again, to stake his life, to risk everything just so that production grows,
profit grows, capital circulates. His personal or her happiness is
totally subordinated to this. This is what I think Walter Benjamin,
the great Frankfurt School companion, thinker, had in mind when he said
capitalism is a form of religion. You cannot explain, account for, a
figure of a passionate capitalist, obsessed with expanded circulation, with
rise of his company, in terms of personal happiness.
I am, of course, fundamentally
anti-capitalist. But let’s not have any illusions
here. No. What shocks me is that most of the critics of
today’s capitalism feel even embarrassed, that's my experience, when you
confront them with a simple question, “Okay, we heard your story . . . protest
horrible, big banks depriving us of billions, hundreds, thousands of billions
of common people's money. . . . Okay, but what do you really
want? What should replace the system?” And then you get one
big confusion. You get either a general moralistic answer, like “People
shouldn't serve money. Money should serve people.” Well,
frankly, Hitler would have agreed with it, especially because he would say,
“When people serve money, money’s controlled by Jews,” and so on, no? So
either this or some kind of a vague connection, social democracy, or a simple
moralistic critique, and so on and so on. So, you know, it’s easy to
be just formally anti-capitalist, but what does it really mean? It’s
totally open.
This is why, as I always repeat, with all my sympathy for
Occupy Wall Street movement, it’s result was . . . I call it a Bartleby
lesson. Bartleby, of course, Herman Melville’s Bartleby, you know,
who always answered his favorite “I would prefer not to” . . . The message of
Occupy Wall Street is, I would prefer not to play the existing
game. There is something fundamentally wrong with the system and the
existing forms of institutionalized democracy are not strong enough to deal
with problems. Beyond this, they don't have an answer and neither do
I. For me, Occupy Wall Street is just a signal. It’s like
clearing the table. Time to start thinking.
The other thing, you know, it’s a little bit boring to
listen to this mantra of “Capitalism is in its last stage.” When this
mantra started, if you read early critics of capitalism, I’m not kidding, a
couple of decades before French Revolution, in late eighteenth
century. No, the miracle of capitalism is that it’s rotting in
decay, but the more it’s rotting, the more it thrives. So, let’s
confront that serious problem here.
Also, let’s not remember--and I’m saying this as some kind
of a communist--that the twentieth century alternatives to capitalism and
market miserably failed. . . . Like, okay, in Soviet Union they did try to get
rid of the predominance of money market economy. The price they paid
was a return to violent direct master and servant, direct domination, like you
no longer will even formally flee. You had to obey orders, a new
authoritarian society. . . . And this is a serious problem: how to abolish
market without regressing again into relations of servitude and domination.
My advice would be--because I don't have simple answers--two
things: (a) precisely to start thinking. Don't get caught into this
pseudo-activist pressure. Do something. Let’s do it, and so
on. So, no, the time is to think. I even provoked some of
the leftist friends when I told them that if the famous Marxist formula was,
“Philosophers have only interpreted the world; the time is to change it” . . .
thesis 11 . . . , that maybe today we should say, “In the twentieth century, we
maybe tried to change the world too quickly. The time is to
interpret it again, to start thinking.”
Second thing, I’m not saying people are suffering, enduring
horrible things, that we should just sit and think, but we should be very
careful what we do. Here, let me give you a surprising
example. I think that, okay, it’s so fashionable today to be
disappointed at President Obama, of course, but sometimes I’m a little bit
shocked by this disappointment because what did the people expect, that he will
introduce socialism in United States or what? But for example, the
ongoing universal health care debate is an important one. This is a
great thing. Why? Because, on the one hand, this debate
which taxes the very roots of ordinary American ideology, you know, freedom of
choice, states wants to take freedom from us and so on. I think this
freedom of choice that Republicans attacking Obama are using, its pure
ideology. But at the same time, universal health care is not some
crazy, radically leftist notion. It’s something that exists all
around and functions basically relatively well--Canada, most of Western
European countries.
So the beauty is to select a topic which touches the
fundamentals of our ideology, but at the same time, we cannot be accused of
promoting an impossible agenda--like abolish all private property or
what. No, it’s something that can be done and is done relatively
successfully and so on. So that would be my idea, to carefully
select issues like this where we do stir up public debate but we cannot be
accused of being utopians in the bad sense of the term.

DARPA is developing brain-control capability (6)

DARPA aims to control prosthetic limbs with brain implants
By Andrew Nusca | March 10, 2010, 6:28 AM PST
As the use of prosthetic limbs increases in military veterans,
the Pentagon is investigating prostheses that are more durable, reliable and
directly controlled using brain implants.
DARPA, the military’s research arm, said it will launch the
next phase of its decade-old Revolutionizing Prosthetics program, which
had an original goal to create a fully-functioning, neurally-controlled human
limb within five years.
Though the agency has made considerable progress —human
trials of the DEKA Arm are underway, and a neurally-controlled arm is
under development at Johns Hopkins University — it hasn’t yet
achieved its goal.
The hurdles:
It has proved difficult to fully integrate human neural
pathways with artificial platforms.
Neural-recording interfaces have short life spans of just
two years.
Neural-recording interfaces don’t extract adequate
information to yield seamless movement from brain to neurons to limbs.
Current prototypes can’t move fast enough: even at 500
events per second, it’s not enough for fluid motion.
To face the challenge, DARPA is launching its Histology
for Interface Stability Over Time program.
The goal: create a neurally-controlled limb that lasts for
70 years and has complete integration with the human body.
Here’s what the agency says (.pdf):
DARPA is soliciting innovative research proposals in the
area of neural-recording interface failure analysis. The HIST program seeks to
develop the technology needed to reliably extract information from the nervous
system, and to do so at a scale and rate necessary to control many
degree-of-freedom (DOF) machines, such as high-performance prosthetic limbs.
Technologies and techniques emerging from this program will enable the construction
of reliable neural-recording interfaces, which will be suitable for clinical
use over the lifetime of an injured soldier (~70 years). Additionally, an
objective understanding of the failure mechanisms will lead to high-throughput
biological testing, due to the discovery of predictive markers linked to a high
probability of failure and other accelerated-testing techniques. Proposed
research should investigate innovative approaches that enable revolutionary
advances in science, devices, or systems. Specifically excluded is research
that primarily results in evolutionary improvements to the existing state of
practice.
In other words: DARPA wants to understand why
neural-recording interfaces are so unreliable, and how failure can be predicted
before an amputee is left without the use of an artificial limb.
The program is structures in three phases over three years.
It’s basically like a hacker contest for prosthetic limbs — DARPA wants
researchers to overload neural systems to find vulnerabilities.
Of particular concern are “implanted cortical microelectrodes,”
or brain implants, which DARPA believes may be the best system for the job.
DARPA is developing brain-control capability (5)
http://www.popsci.com/technology/article/2010-09/darpa-wants-mind-control-keep-soldiers-sharp-smart-and-safe
DARPA has been trying to crawl inside the minds of soldiers
for a while now, but a new ultrasound technology could let them get deeper
inside than ever. Working under a DARPA grant, a researcher at Arizona State is
developing transcranial pulsed ultrasound technology that could be
implanted in troops’ battle helmets, allowing soldiers to manipulate brain
functions to boost alertness, relieve stress, or even reduce the effects of
traumatic brain injury.
Manipulating the brain to enhance warfighting capabilities
and maintain mental acuity on the battlefield has long been a topic of interest
for DARPA and various military research labs, but the technology to do so
remains limited. Deep brain stimulation (DBS), for instance, requires
surgically implanted electrodes to stimulate neural tissues, while
less-invasive methods like transcranial magnetic stimulation (TMS) possess
limited reach and low spatial resolution.
But Dr. William J. Tyler, an assistant professor of life
sciences at ASU, writes on the DoD’s “Armed With Science” blog: “To overcome
the above limitations, my laboratory has engineered a novel technology which
implements transcranial pulsed ultrasound to remotely and directly stimulate
brain circuits without requiring surgery. Further, we have shown this
ultrasonic neuromodulation approach confers a spatial resolution approximately
five times greater than TMS and can exert its effects upon subcortical brain circuits
deep within the brain.”
Tyler’s technology, packaged in a warfighter’s helmet, would
allow soldiers to flip a switch to stimulate different regions of their brains,
helping them relieve battle stress when it’s time to get some rest, or to boost
alertness during long periods without sleep. Grunts could even relieve pain
from injuries or wounds without resorting to pharmaceutical drugs. More
importantly, in the periods after brain trauma ultrasound technology could
reduce swelling and metabolic damage that is often the root cause of lasting
brain damage.

IBM produces first 'brain chips'
http://www.bbc.co.uk/news/technology-14574747
IBM has developed a microprocessor which it claims comes
closer than ever to replicating the human brain.
The system is capable of "rewiring" its
connections as it encounters new information, similar to the way biological
synapses work.
Researchers believe that by replicating that feature, the
technology could start to learn.
Cognitive computers may eventually be used for understanding
human behaviour as well as environmental monitoring.
Dharmendra Modha, IBM's project leader, explained that they
were trying to recreate aspects of the mind such as emotion, perception,
sensation and cognition by "reverse engineering the brain."
The SyNAPSE system uses two prototype "neurosynaptic
computing chips". Both have 256 computational cores, which the scientists
described as the electronic equivalent of neurons.
One chip has 262,144 programmable synapses, while the other
contains 65,536 learning synapses.
Man machine
In humans and animals, synaptic connections between brain
cells physically connect themselves depending on our experience of the world.
The process of learning is essentially the forming and strengthening of
connections.
A machine cannot solder and de-solder its electrical tracks.
However, it can simulate such a system by "turning up the volume" on
important input signals, and paying less attention to others.
IBM has not released exact details of how its SyNAPSE
processor works, but Dr Richard Cooper, a reader in cognitive science at
Birkbeck, University of London said that it likely replicated physical
connections using a "virtual machine".
Instead of stronger and weaker links, such a system would
simply remember how much "attention" to pay to each signal and alter
that depending on new experiences.
"Part of the trick is the learning algorithm - how
should you turn those volumes up and down," said Dr Cooper.
"There's a a whole bunch of tasks that can be done just
with a relatively simple system like that such as associative memory. When we
see a cat we might think of a mouse."
Some future-gazers in the cognitive computing world have
speculated that the technology will reach a tipping point where machine
consciousness is possible.
However, Dr Mark Bishop, professor of cognitive computing at
Goldsmiths, was more cautious.
"[I] understand cognition to be something over and
above a process simulated by the execution of mere computations, [and] see such
claims as verging on the magical," he said.
IBM's work on the SyNAPSE project continues and the company,
along with its academic partners, has just been awarded $21m (£12.7m) by the US
Defense Advanced Research Projects Agency (DARPA).
