4.         Neuroenhancement

Normality …As is well known, a large part of twentieth-century though—from Freud, let us say, to Foucault—has defined normality against its opposite:  against pathology, emargination, repression.  Normality is seen not as a meaning-ful, but rather as an unmarked entity.  The self-defensive result of a “negation” process, normality’s meaning is to be found outside itself:  in what it excludes, not in what it includes….  …For two centuries now, Western societies have recognized the individual’s right to choose one’s own ethics and idea of “happiness,” to imagine freely and construct one’s personal destiny—rights declared in proclamations and set down in constitutions but that are not, as a result, universally realizable, since they obviously give rise to contrasting aspirations.  And if a liberal-democratic and capitalist society is without a doubt one that can best “live with” conflict, it is equally true that, as a system of social and political relationships, it too tends to settle itself into an operational mode that is predictable, regular, “normal.”  Like all systems, it demands agreement, homogeneity, consensus.  How can the tendency toward individuality, which is the necessary fruit of a culture of self-determination, be made to coexist with the opposing tendency to normality, the offspring, equally inevitable of the mechanism of socialization?  This is the first aspect of the problem, complicated and made more fascinating still by another characteristic of our civilization, which, having always been pervaded by the doctrines of natural rights, cannot concede that socialization ins based on a mere compliance with authority.  It is not enough that the social order is “legal”; it must also appear symbolically legitimate.  It must draw its inspiration from values recognized by society as fundamental, reflect them, and encourage them.  Or it must at least seem to do so.  Thus it is not sufficient for modern bourgeois society simply to subdue the drives that oppose the standards of “normality.”  It is also necessary that, as a “free individual,” not as a fearful subject but as a convinced citizen, one perceives the social norms as one’s own.  One must internalize them and fuse external compulsion and internal impulses into a new unity until the former is no longer distinguishable from the latter.  This fusion is what we usually call “consent” or “legitimation.” - Franco Moretti

"The chemical or physical inventor is always a Prometheus. There is no great invention, from fire to flying, which has not been hailed as an insult to some god. But if every physical and chemical invention is a blasphemy, every biological invention is a perversion. There is hardly one which, on first being brought to the notice of an observer from any nation which had not previously heard of their existence, would not appear to him as indecent and unnatural." from J. B. S. Haldane, DAEDALUS or Science and the Future. A paper read to the Heretics, Cambridge, on February 4th, 1923

6.         Development, nature-nurture

On Tuesday was discussion of normal brain development in children and then the effects (both positive and negative) of "drugs" on the brain. By "drugs", I mean both illegal drugs taken by the mother during pregnancy and "smart drugs", which are cognitive enhancers that could play a major role in child development in the future. For class, consider whether or not smart drugs should be allowed for child development and what exactly would constitute a "smart drug". Keep in mind the effects of various other neurological stimulants and depressants on the brain, such as alcohol and drugs.

U.S. Supreme Court Decisions on Court-Ordered Medication

 

U.S. Constitution, Amendment V

 

No person shall be [...] compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

Amendment XIV

[...] No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. [...]

 

1.  Washington v. Harper (1990)

 

Respondent Harper has been a ward of the Washington state penal system since his 1976 robbery conviction. Both as an inmate and while temporarily on parole, he received psychiatric treatment, including the consensual administration of antipsychotic drugs. He has engaged in violent conduct, and his condition has deteriorated when he did not take the drugs. On two occasions, he was transferred to the Special Offender Center, a state institute for convicted felons with serious mental illness, where he was diagnosed as suffering from a manic-depressive disorder. While at the Center, he was required to take antipsychotic drugs against his will pursuant to an SOC Policy.  The Policy provides:

 

- that, if a psychiatrist orders such medication, an inmate may be involuntarily treated only if he

(1) suffers from a "mental disorder" and (2) is "gravely disabled" or poses a "likelihood of serious

harm" to himself or others;

 

- that, after a hearing and upon a finding that the above conditions are met, a special committee

consisting of a psychiatrist, a psychologist, and a Center official, none of whom may be currently

involved in the inmate's diagnosis or treatment, may order involuntary medication if the

psychiatrist is in the majority;

 

- and that the inmate has the right to notice of the hearing, the right to attend, present evidence,

and cross-examine witnesses, the right to representation by a disinterested lay adviser versed in

the psychological issues, the right to appeal to the Center's Superintendent, and the right to

periodic review of any involuntary medication ordered. In addition, state law gives him the right to

state-court review of the committee's decision.

 

Both of the involuntary treatment proceedings were conducted in accordance with the SOC Policy.  During his second stay at the Center, but before his transfer to a state penitentiary, Harper filed suit...

 

 

i.  On what grounds can psychiatric medication be involuntarily administered to a prisoner?

ii.  Was this policy sufficient to protect Harper’s rights?  (The decision to medicate in this case was

made by a committee hearing, not by a state court.)

 

 

2.  Riggins v. Nevada (1992)

 

When petitioner Riggins, while awaiting a Nevada trial on murder and robbery charges, complained of hearing voices and having sleep problems, a psychiatrist prescribed the antipsychotic drug Mellaril. After he was found competent to stand trial, Riggins made a motion to suspend the Mellaril's administration until after his trial, arguing that its use infringed upon his freedom, that its effect on his demeanor and mental state during trial would deny him due process, and that he had the right to show jurors his true mental state when he offered an insanity defense. After hearing the testimony of doctors who had examined Riggins, the trial court denied the motion with a one page order giving no indication of its rationale. At Riggins' trial, he presented his insanity defense and testified, was convicted, and was sentenced to death.

 

i.  Did the forced administration of medication infringe on Riggins’s rights?

ii.  What is the distinction here between insanity and incompetence?

                iii.  Riggins claimed that the medication altered and impaired his testimony.  What side effects can be

caused by antipsychotic medication, and how can these affect court proceedings?

 

    Where is Riggins today?

 

3.  Sell v. United States (2003)

 

Charles Sell, once a practicing dentist, has a long and unfortunate history of mental illness.  In September 1982, after telling doctors that the gold he used for fillings had been contaminated by communists, Sell was hospitalized, treated with antipsychotic medication, and subsequently discharged.  In June 1984, Sell called the police to say that a leopard was outside his office boarding a bus, and then he asked the police to shoot him.  Sell was again hospitalized and subsequently released.  On various occasions, he complained that public officials... were trying to kill him.  In April 1997, he told law enforcement personnel that he “spoke to God last night,” and that “God told me every [FBI] person I kill, a soul will be saved.”

 

In May 1997, the Government charged Sell with submitting fictitious insurance claims for payment.  A Federal Magistrate Judge, after ordering a psychiatric examination found Sell “currently competent,” but noted that Sell might experience “a psychotic episode” in the future.  The judge released Sell on bail.  A grand jury later produced a superseding indictment charging Sell and his wife with 56 counts of mail fraud, 6 counts of Medicaid fraud, and 1 count of money laundering.

In early 1998, the Government claimed that Sell had sought to intimidate a witness. The Magistrate held a bail revocation hearing. Sell’s behavior at his initial appearance was, in the judge’s words, “totally out of control,” involving “screaming and shouting,” the use of “personal insults” and “racial epithets,” and spitting “in the judge’s face.”  A psychiatrist reported that Sell could not sleep because he expected the FBI to “come busting through the door,” and concluded that Sell’s condition had worsened.  After considering that report and other testimony, the Magistrate revoked Sell’s bail.

In April 1998, the grand jury issued a new indictment charging Sell with attempting to murder the FBI agent who had arrested him and a former employee who planned to testify against him in the fraud case. The attempted murder and fraud cases were joined for trial.

In early 1999, Sell asked the Magistrate to reconsider his competence to stand trial. The Magistrate sent Sell to the United States Medical Center for Federal Prisoners at Springfield, Missouri, for examination. Subsequently the Magistrate found that Sell was “mentally incompetent to stand trial.”  He ordered Sell to “be hospitalized for treatment” at the Medical Center for up to four months, “to determine whether there was a substantial probability that [Sell] would attain the capacity to allow his trial to proceed.”

Two months later, Medical Center staff recommended that Sell take antipsychotic medication. Sell refused to do so. The staff sought permission to administer the medication against Sell’s will. That effort is the subject of the present proceedings.

Man and the Machines: It's time to start thinking about how we might grant legal rights to computers. by Benjamin Soskis in Legal Affairs

Top 500 supercomputers -- The TOP500 project was started in 1993 to provide a reliable basis for tracking and detecting trends in high-performance computing. Twice a year, a list of the sites operating the 500 most powerful computer systems is assembled and released. The best performance on the Linpack benchmark is used as performance measure for ranking the computer systems. The list contains a variety of information including the system specifications and its major application areas.

The Blue Brain Project -- June 6, 2005 – IBM and The Ecole Polytechnique Fédérale de Lausanne (EPFL) are today announcing a major joint research initiative – nicknamed the Blue Brain Project – to take brain research to a new level.  Over the next two years scientists from both organizations will work together using the huge computational capacity of IBM’s eServer Blue Gene supercomputer to create a detailed model of the circuitry in the neocortex – the largest and most complex part of the human brain. By expanding the project to model other areas of the brain, scientists hope to eventually build an accurate, computer-based model of the entire brain.

Brain fingerprinting
Farwell, Brain Fingerprinting Laboratories  
"Brain Fingerprinting Laboratories, Inc. has developed and patented EEG/P300 based testing systems that determine with extremely high accuracy whether or not specific information is stored in a person’s memory. The test measures individual brain-wave responses to relevant words, pictures or sounds presented by a computer. The measurements are recorded in fractions of a second after the stimulus is presented, before the subject is able to formulate or control a response. In a major milestone for the company, the results of this patented testing methodology have been ruled admissible in court as scientific evidence. The technology has many exciting applications in several very large markets: national security, medical diagnostics, advertising, insurance fraud and in the criminal justice system."

Center for Cognitive Liberty
"The CCLE is opposed to compulsory Brain Fingerprinting because it threatens cognitive liberty and violates the sanctity of the mind. Compelled Brain Fingerprinting intrudes on the individual's right to mental privacy, it should not be mandated by courts, governments, corporations, or any other institution."

Neuroethics in the arts

Books (in no particular order)

Flowers for Algernon by Daniel Keyes

Originally a short story, then expanded into a novel (which won a Nebula) and expanded into a 1980 Broadway musical.  See some fairly good summaries and reviews at <http://www.amazon.com/gp/product/0553274503/104-5607215-9051107?v=glance&n=283155>
It concerns a mentally challenged man, Charlie, who undergoes an experimental brain operation and dramatically increases in intelligence.  Then the mouse who first underwent the operation begins to deteriorate... Its a really good look at intelligence, and the horrible possibilities of artificially stimulating it.

Oryx and Crake by Margaret Atwood
It is a futuristic novel where marketing has become increasingly individualized.  A rather crazy genius tinkers with the human genome to the point of extinction for today’s humans and creates a ‘super-society’ which ‘fixes’ today’s problems, such as unsatisfied sexuality, violence, etc - but at the price of their humanity according to some.  It is definitely an interesting read.


Movies (in no particular order)      

The Matrix
Starring Keanu Reeves, humans are attached to giant machines and serve as 'batteries' for a race of aliens that have taken over the earth.  The entire world is a fiction produced in the minds of all humans.  Though imagining this scenario is a bit of a stretch, it does bring up interesting issues concerning use of embryos, dreams, and neurological connections.

Minority Report
Starring Tom Cruise, the year is 2054, and psychics have enabled the development of a 'pre-crime' division which can stop murderers before they commit the crime.  When the main character is charged with a murder he has no intention of committing, a race begins.  Neuroethical issues include questions of intent vs. action, neurological transplants, and brain-tailored advertising are clearly shown several times.
I Robot
It gets into the question of what makes a person valuable.  If all a person is made of is neurons firing, what should the difference in rights be between a robot and a perso?  Is there more to a person than the complex workings of his or her brain?  The Laws of Robotics formulated by the author of the original stories,  Isaac Asimov, are central to this  movie

The Laws of Robotics
First Law:  A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
Second Law:  A robot must obey orders given it by human beings, except where such orders would conflict with the First Law.
Third Law:  A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

For interesting discussion see Roger Clarke, Asimov's Laws of Robotics Implications for Information Technology, Published in two parts, in IEEE Computer 26,12 (December 1993) pp.53-61 and 27,1 (January 1994), pp.57-66

The Wikipedia entry is also very useful.

The Island
Concerns cloning.

Million Dollar Baby
Concerns euthenasia.

Bicentennial Man
A movie with Robin Williams, in which an android actually has creativity, thought, and desires to become human.  He changes and gains biological organs, skin, everything except a brain.  He even dies...and eventually is granted the title of 'humanity'.

Gattaca

A movie about genetic engineering among humans creating a new underclass, based on genetic superiority and 'knowledge' of physical or mental flaws before they occur.  Chilling in its prediction of a society not so far away from our own.

Eternal Sunshine of the Spotless Mind

A girl erases her boyfriend from her mind, provoking him to do the same. The movie asks whether we have the same inclinations and personalities even without our memories (for example, the couple finds each other again and begins dating). Also, is it ethical to remove people's memories, even at their own request, and what are the possibilities for abuse?
