Chimica dell'anima

Mind drugs - Future Imperfect by David Friedman
***
UNA VITA MIGLIORE GRAZIE ALLA CHIMICA
At least since the discovery of alcohol, humans have used drugs to affect the mind.
Note: L' UOMO SI DROGA DA SEMPRE. È UNA TRADIZIONE VENERANDA Edit
In many ways this will be a good thing; already drugs provide substantial benefits to some sufferers from mental disorders.
Note: L"ASPETTO POSITIVO: MENO SOFFERENZA. MICA PAGLIA.

COSA DESIDERA? PIACERE O FELICITÀ ? QUI SI VENDE DI TUTTO.
In most contexts we consider happiness and pleasure good things. Jeremy Bentham, one of the most influential philosophers of the nineteenth century, offered a simple standard for judging everything - its effect on utility, happiness, the excess of pleasure over pain in human life.
Note: DI SOLITO IL PIACERE È BUONA COSA. PERCHÈ CONDANNARLO? EPPURE LO SI FA CONTINUAMENTE  Edit
Supporters of laws against recreational drugs base their support on a variety of factual claims, some true, some false. It is not true that smoking marijuana makes people go crazy and commit violent crimes, as claimed in "Reefer Madness," a movie that played an important role in inspiring the original anti-marijuana legislation. It is true that people on LSD are frequently incapable of performing ordinary tasks such as driving a car safely or conducting a coherent conversation.
Note: ARGOMENTI CONTRO LA DROGA. A VOLTE FONDATI ALTRE VOLTE  MENO Edit
Whether or not the negative claims are true of some or all current recreational drugs, they are unlikely to be true of all future recreational drugs. The more we know about how the human mind functions, the better we will become at creating drugs that give pleasure without serious negative side effects. Unless, of course, it is pleasure itself that is the problem.
Note: LA DROGA DEL FUTURO PROBABILMENTE ELUDERÀ QUESTE CRITICHE E POTREMO VENIRE AL PUNTO. LA DROGA DEL FUTURO ANNULLERÀ GLI EFFETTI COLLATERALI NEGATIVI.  BASTA PROBLEMI.... A MENO CHE IL PROBLEMA NON SIA IL PIACERE IN SÈ Edit
If we can create a chemical that gives us pleasure, and if pleasure is a good thing, why don't we come already equipped for pleasure on demand?
Note: UNA COSA CHE DÀ DA PENSARE: PERCHÈ L' EVOLUZIONE NON CI HA DOTATO DI UN PIACERE SENZA DANNI COLLATERALI? Edit
The obvious answer is that we are designed by evolution not for happiness but for reproductive success.
Note: UNA RISPOSTA OVVIA Edit
If pleasure drugs are too good, they might interfere not merely with reproductive success but with physical survival.
Note: IL PIACERE PUÒ INTERFERIRE Edit
one more minute of intense pleasure is worth more to them than food or drink. If we accept this argument, the implication is not that pleasure drugs are bad but only that they should be used in moderation.
Note: ESEMPIO Edit
Food, after all, is consumed largely to give us sensual pleasure. A minimum-cost, full-nutrition diet, based on flour, peanut butter, cabbage, and other high nutrition/low cost ingredients, comes to less than two dollars a day. j The rest of what we spend is for pleasure.
Note: FACCIAMO UN CASO DIVERSO DALLA DROGA: CIBO E PIACERE Edit
The current real-world problem of trading short-term pleasure for more important long-term goals is, arguably, not the starvation ofNiven's wirehead but its opposite: obesity.
Note: NELLA NOSTRA EPOCA IL PIACERE INTERFERISCE ATTRAVERSO L'OBESITÀ PIÙ CHE ATTRAVERSO LA MALNUTRIZIONE. DROGHE ALTERNATIVE AL CIBO FAREBBERO BENE A MOLTI OBESI CHE SI DISTRARREBBERO DA UN PIACERE PER LORO NOCIVO CON UN ALTRO PIACERE Edit
A more general argument against pleasure drugs is that simple pleasure is not all that matters, as suggested not merely by philosophers but by observed behavior. Few couples have sex as frequently as would be physically possible; few single individuals masturbate as often as would be physically possible. If we imagine someone spending most of his life in a drug-induced haze, we may suspect that, however intense his pleasure, he is not really happy. This suggests the least interesting response to the possibility of pleasure drugs - that they don't work,

SE IL PIACERE NON TI CONVINCE, CHE NE DICI DELLA FELICITÀ?
Since we are not limited to current technology, replace pleasure with happiness, the state of mind to which we think of pleasure as one input.
Note: RIMPIAZZATE IL PIACERE CON LA FELICITÀ QUANDO PENSATE ALLA DROGA DEL FUTURO Edit
Studies of happiness suggest that happy people stay happy even when circumstances change, at least once they have had time to adjust to the changes.
Note: LA FELICITÀ È SPESSO QUESTIONE DI CARATTERE. MA UN CARATTERE, DOMANI, POTRÀ ESSERE COSTRUITO IN LABORATORIO. COSA LO VIETA? Edit
So consider, not a pleasure drug, but a happiness drug,
Note: LA DROGA PERFETTA. OBIEZIONI? Edit
If you could, would you? Should you? One possible answer is that such happiness is unnatural. Again the argument is that we have been designed by evolution, and evolution is much better at neurochemistry than we are. If brain chemistry that made us happy was a good thing, we would all already have it.' The argument already offered for pleasure can be recycled for happiness.
Note: IL CONCETTO DI INNATURALE. QUANTO DETTO PER IL PIACERE IN FONDO VALE ANCHE PER LA FELICITÀ: SE LA COSA FA PER NOI PERCHÈ L'EVOLUZIONE NON CI HA PROCURATO NIENTE DELMGENERE?
While evolution may indeed be a very good biochemist, its objectives are not the same as ours. From the viewpoint of evolution, we are simply machinery by which genes make other genes. The design objective is reproductive success, the ability to increase the frequency of our genes in future generations. That is not my design objective for me;
Note: POSSIAMO DISSOCIARCI DALL'EVOLUZIONE NATURALE? Edit
Not only does evolution have the wrong objective, its designs are also out of date. Humans have long generations and so evolve slowly. Such evidence as we have suggests that we are adapted not to current circumstances but to the hunter-gatherer societies in which our species spent most of its existence.
Note: D'ALTRONDE, L'EVOLUZIONE FA PARECCHI ERRORI, QUESTO È ACCLARATO. BASTEREBBE UNA SCORSA AI BIAS COGNITIVI CHE CI AFFLIGGONO.
A second and more interesting objection is that utilitarianism is wrong, that happiness is not all that matters.
Note: ALTRA OBIEZIONE: NON CONTA SOLO LA FELICITÀ Edit
consider two alternative lives I might live. One is the life I have lived. It has been, on the whole, a happy one.... The other is the life I might have lived if provided with suitable drugs, sufficient to make me at every moment of that life at least as happy as in the life I led. It is true that in that life I would not have had the pleasures of children, books, and other accomplishments. But I would have been compensated for that lack by an artificial increase in whatever brain chemicals connect the cause of accomplishment to the effect of happiness. Which life is more worth living?

DROGA E PRESTAZIONI

Everyone seems to agree that it is a bad thing for athletes to use steroids, but it is not entirely bad a diet... Athletes have, after all, been using diet and exercise to improve their performance for thousands of years, as well as a variety of older drugs. Why does the process suddenly become sinful when they switch to steroids?
Note: PERCHÈ PER UN ATLETA È MALE PRENDERE UNO STEROIDE ED È BENE FARE DIETE O ALLENARSI? Edit
One answer is that since steroid use is currently prohibited, those who use steroids are getting an unfair advantage. But that does not explain why they are currently prohibited when other ways of getting an advantage are not.
Note: RISPOSTA ELUSIVA: LO STEROIDE È VIETATO E ASSUMERLO È SCORRETTO. MA CIÒ NON RISPONDE ALLA DOMANDA Edit
A second answer is that we are afraid young athletes, with inadequate concern for their own future, will do themselves serious damage in the process of trying to win. But while taking steroids may reduce life expectancy

Why is our paternalism so selective?'

VENIAMO ALLORA ALLA RISPOSTA PIÙ INTERESSANTE
The most interesting answer… Arguably, most of what we care about is the relative, not absolute, ability of the athletes.

competition via steroid use is a mistake.... Both teams, boxers, or runners get a little better, their relative ability is unaffected, the fans are no happier and the athletes die a little younger.

Ritalin, for example, is usually thought of as medication for Attention Deficit Disorder (ADD). It turns out, however, that one cannot tell if someone has ADD by giving him Ritalin and seeing if his concentration improves, because Ritalin improves everyone's concentration.

Perhaps when the due date for a paper approaches, a student given to procrastination might want to obtain some modafinil,10 a drug that appears to eliminate the need for sleep
Note: ESAMI. DROGHE CHE ELIMINANO IL SONNO Edit
One argument for prohibiting the use of such drugs by those taking the bar exam, or SATs, or a final, is that they distort the information that the exam produces. A law firm deciding whether to hire you doesn't want to know how good a lawyer you are when you are under the influence of Ritalin
Note: ALTRO ARGOMENTO CONTRO LE DROGHE NELLA VITA REALE: LE DROGHE PRODUCONO INFO DISTORTE. Edit
That makes sense as long as we are only talking about temporary effects. The question becomes more interesting if we consider a drug that can be used on a regular basis
Note: E I DROGATI REGOLARI? L' INFO CHE GENERA LA LORO PRESTAZIONE NON È AFFATTO DISTORTA Edit
That argument reflects a fundamental misunderstanding of economic competition. If you and I are runners and both use steroids, both run a little faster and you still win the race. Nothing is gained and, if steroids have undesirable side effects, something is lost. But if you and I are house carpenters who use an improved version of modafinil to increase both labor and leisure, working ten hours out of twenty-two instead of eight out of sixteen, the result is that more houses get built.
Note: ORA CAPIAMO CHE L'OBIEZIONE CHE VALE PER LA DROGA NELLO SPORT NON VALE FUORI: FUORI C'È SEMPRE QUALCUNO CHE TRAE VANTAGGIO DALLE SUPERPRESTAZIONI. IN ALTRI TERMINI: FUORI LA PRESTAZIONE ASSOLUTA DOMINA SU QUELLA RELATIVA Edit
"Competition" is a misleading term because it suggests that, as in athletic contests, all that matters is who wins.
Note: COMPETIZIONE: TERMINE FUORVIANTE PER DESCRIVERE IL MERCATO Edit
An alternative explanation, and one that provides at least a partial explanation of hostility to many different technologies, is that people are simply conservative, skeptical of anything new, "unnatural," despite the unnatural nature of virtually everything we currently eat, drink, or wear.

DROGHE E PERSONALITÀ: CHI SONO IO?
As we develop ways of easily obtaining much more intense pleasures, there is some risk that we may be tempted into giving up long-term benefits in exchange for short-term benefits even when we should not. This raises an obvious question: What does "should not" mean?
Note: DROGA. BENFICI A BREVE E A LUNGO. UN TRADE OFF Edit
An approach to that question that I find intuitively appealing is to think of myself as two people in one, a long-term planner and a short-term current utility maximizer.
Note: PENSIAMOCI COME DUE PERSONE IN LOTTA TRA LORO. METAFORA SCHIZOFRENICA Edit
This way of looking at it suggests an intriguing possibility. Perhaps the problem with pleasure drugs can be dealt with by personality drugs.

Perhaps, as we learn more about how the brain works, we will discover that the difference reflects some difference in brain chemistry.

Consider, for example, what we already know about the effects of dopamine, a neurotransmitter that plays an important role in brain chemistry. A shortage of dopamine in the brain results in an indecisive personality;

There are drugs that induce temporary amnesia, such as Rohypnol, sometimes called the date rape drug. There are drugs such as alcohol and marijuana that relax people and make it harder to think clearly.

One odd set of experiments involving the reaction of some people to smelling other people's perspiration suggest that there may be human pheromones, compounds that make someone smell sexy to someone else; perhaps some perfume actually works.'4

Still more disturbing is the possibility of drugs that make the consumer credulous, willing to believe whatever he is told, or obedient, or loyal. There is some evidence that oxytocin has such an effect.

So far in the discussion of control drugs I have been assuming that they are given to people without their consent.

There are quite a lot ofjobs for which loyalty is an important qualification.... After calculating the cost of watching everyone all the time, I decide to offer two different employment contracts, one paying $50,000 a year, one $100,000. There is only one difference between the two contracts: The second one requires the employee to consume a drug that makes him loyal to the firm.

DROGA E AMORE
Falling in love is for some people an intensely pleasurable, indeed addictive, experience, which may explain why some men fall intensely in love with one woman and then, after their efforts meet with success, lose interest and fall in love with another. A famous example is Giacomo Casanova,

Humans rarely stay in love; typically, the feelings and associated behavior last for months, not years. Sometimes love is succeeded by attachment, a behavior pattern associated with less intense emotions and one that can, with luck, last a lifetime.
Note: ATTACCAMENTO Edit
Suppose, as seems likely enough, that further research makes it possible to control them, to fall in and out of love, to maintain or destroy the emotions of romantic attachment, to turn love and lust on or off, with a pill, a patch, an injection. What consequences would follow?
Note: IPOTESI: L'AMORE PUÒ ESSERE INDOTTO O REPRESSO ARTIFICIALMENTE Edit
The consequences of involuntary use are obvious and unattractive: a pill that makes a beautiful woman fall in love or, for shorter-term objectives, lust, with you. What about voluntary use?
Note: USO VOLONTARIO E INVOLONTARIO DELLA DROGA DELL'AMORE Edit
Many years ago I spent a long airplane flight - from Bombay to Sydney - next to a woman from southern India, flying out to join her husband. She came from a society where arranged marriages were taken for granted. Her husband had been selected for her by her parents, although she had then met him before consenting to the arrangement. I came from a society where it was taken for granted that individuals found and selected their own mates. She accepted her society's arrangements and was intrigued by the odd way we did things; I felt much the same in the other direction. And she was not a stick figure in a history or anthropology text but a living, breathing human being, obviously intelligent and thoughtful. Furthermore, on at least our small sample, the superiority of the Western system was far from clear; she was happily married, I recently divorced.
Note: L'AMORE A COMANDO ESISTE GIÀ: MATRIMONI COMBINATI Edit
Perhaps in the brave new world of modern chemistry one will be able to get the best of both worlds. First I select a spouse by some suitably calm and objective analysis, making use of the services of a professional matchmaker to find a woman ideally suited to be my wife - one requirement being, of course, that I am ideally suited to be her husband. After she and I have agreed on the match, either just before or just after the wedding, we take our pills, look into each other's eyes, and fall deeply and passionately in love. After six months or so of ecstatic but distracting bliss - both of our employers are beginning to worry about declining job performance - we switch the prescription from passion to attachment and so shift into a long and satisfying marriage. If on some suitable future occasion, say a tenth anniversary, we feel in need of a  second honeymoon
