Il bene dentro

Nel libro “The Moral Sense” James Wilson intende sostenere che siamo dei moralisti nati.
Lo siamo anche e soprattutto quando cerchiamo di non esserlo.
***
Di questi tempi la virtù gode di cattiva reputazione
… Virtue has acquired a bad name. To young people it is the opposite of having fun, to older ones it is a symbol of lost virtue that politicians now exploit for partisan purposes…
Eppure il moralismo è ipertrofico (stampa, radio, tv non fanno altro che prediche e tirate moralistiche mascherate…)…
… Yet the daily discourse of ordinary people is filled with oblique references to morality…
Giusto qualche preoccupazione linguistica per non farlo emergere immediatamente come tale, e poi vai a trinciar giudizi da mane a sera…
… This preoccupation, like the adjectives with which we express it—loyal, kind, or nice; disloyal, selfish, or rude—is with the language of morality, even though we often disguise it in the language of personality….
Tesi: l’uomo è un moralista naturale
… I endeavor to show that mankind has a moral nature…
***
Ma perché il moralista che è in noi dovrebbe nascondersi?
Forse perché crediamo che i giudizi morali siano arbitrari. Il culto della scienza avrebbe questo effetto collaterale…
… I believe it is because we have learned, either firsthand from intellectuals or secondhand from the pronouncements of people influenced by intellectuals, that morality has no basis in science or logic. To defend morality is to defend the indefensible…
Siamo stati educati da Darwin che tutto è utilitarismo…
… Charles Darwin taught us, we suppose, that a person is the isolated product of a competition for survival among selfish genes coping with material circumstances; his or her morals are entirely utilitarian and selfcentered…
Da Freud che ogni morale è repressione…
… Sigmund Freud taught us, we suppose, that guilt is an unhealthy expression of a repressed impulse…
Da Marx che tutto cela rapporti di forza…
… Karl Marx taught us, we suppose, that we are driven entirely by economic impulses…
Con maestri del genere lo scetticismo è dovuto.
Ma il senso comune ci dice ben altro…
… That spirit has been one of skepticism. Science has challenged common sense…
Ci sono poi anche gli antropologi, quelli per cui tutto è cultura
… the dominant tradition in modern anthropology has held that those customs are entirely the product of culture, and so we can conclude that man has no nature apart from his culture….
Il relativismo ha vinto…
… Many people have persuaded themselves that no law has any foundation in a widely shared sense of justice…
Nell’educare i bambini siamo terrorizzati dall’indottrinamento
… Many people have persuaded themselves that children will be harmed if they are told right from wrong…
Preferiamo presentare ai piccoli i valori e lasciare che scelgano da soli (a costo di procurare ansie inutili)…
… they should be encouraged to discuss the merits of moral alternatives. This is called “values clarification,”…
Ma una ricetta del genere crea più confusione che educazione.
Eppure c’è riluttanza nel giudicare le abitudini altrui
… Many people have persuaded themselves that it is wrong to judge the customs of another society since there are no standards apart from custom on which such judgments can rest…
Questa riluttanza viene chiamata “tolleranza”.
In questo clima lassista non meraviglia che prosperino droga e teppismo giovanile…
… people who have persuaded themselves to embrace nonmoral standards should not be surprised if young people who have heard these ideas grow up taking drugs, cheating on tests, and shooting their enemies…
Ma crediamo veramente nel relativismo?…
… Do we really want to have the utterly malleable, slightly cynical, superficially tolerant, wholly transparent human nature that we claim we have?…
Probabilmente no poiché, una volta messo a punto un linguaggio che non ci dia sensi di colpa, giudichiamo eccome, giudichiamo a raffica. E i “tolleranti” in particolare.
Eppure quel che uno pensa di essere continua a contare…
… We must be careful of what we think we are, because we may become that…
Le buone maniere vogliono che il giudizio vada espresso in privato. Il giudizio pubblico è qualcosa di rozzo e tipico dei fanatici…
… When they speak of virtue, they must do so privately, in whispers, lest they be charged with the grievous crime of being “unsophisticated” or, if they press the matter, “fanatics.”…
***
Prendiamo il caso del crimine: colpa della società o della mancanza dei valori?…
… When we try to explain the high rate of crime, some argue that it is the result of young people’s no longer having the right values and others claim that it is caused by social barriers that have prevented young people from attaining their values by legitimate means… Hardly anyone can discuss the problems of public schools without claiming or denying that these failures are the result of the schools’ teaching the wrong values, or no values…
Trattasi di vera e propria guerra culturale
… We are engaged in a cultural war, a war about values. It is not a new war; it has been going on for centuries as part of a continuing struggle at national self-definition. Once the issues were slavery, temperance, religion, and prostitution; today they are divorce, illegitimacy, crime, and entertainment…
Per molti i “valori” sono solo preferenze soggettive (come i gusti del gelato)…
… But what do we mean by a “value”? A taste? A preference? A belief? A moral principle? A binding obligation?… The word “values” finesses all of the tough questions. It implies a taste or preference and recalls to mind the adage that there is no disputing tastes…
Ma il buon senso si oppone…
… beneath that tolerance there lurks among many of us a worrisome uncertainty—some of us doubt that we have a defensible philosophy or credible conviction that we would want to impose…
E poi in tutto questo  c’è qualcosa di strano: chi ritiene che i valori siano “gusti” poi li difende fino alla morte
… But of course we don’t really mean that our beliefs are no more than tastes, because when we defend them—to the extent we can—our muscles tighten and our knuckles grow white… That is not the way we discuss our taste for vanilla ice cream. We are aware, then, that some values are more important than others…
Sotto c’è la nostra ipocrisia: siamo dei moralisti e negarlo non serve a nulla. Quanto più lo neghiamo, tanto più la cosa emerge.
Se siamo dei moralisti la “value clarification” è qualcosa di inadatto da propinare ai bambini…
… We suspect that “values clarification” is not the best way to teach the young but lack the confidence to assert a value that ought to be defended…
Se siamo dei moralisti naturali la scienza non puo’ essere nemica della morale
… Students of child development have observed the emergence of the moral sense and given respectful and thoughtful accounts of it. However much the scientific method is thought to be the enemy of morality, scientific findings provide substantial support for its existence and power….
Tesi: il moralismo non è né evitabile, né arbitrario
… tries to make clear that people necessarily make moral judgments, that many of those judgments are not arbitrary or unique to some time, place, or culture…
Avere un senso morale significa intuire l’esistenza di valori reali…
… By a moral sense I mean an intuitive or directly felt belief about how one ought to act when one is free to act voluntarily (that is, not under duress)…
Era già vero per Aristotele…
… you cannot discuss morality with someone who is devoid of any moral sense.3 The fact that you can discuss morality with practically anyone suggests to me that the word “ought” has an intuitively obvious meaning…
Altri precursori…
… This effort is a continuation of work begun by certain eighteenth-century English and Scottish thinkers, notably Joseph Butler, Francis Hutcheson, David Hume, and Adam Smith…
E oggi la biologia conferma…
… What I seek to add to this tradition is a knowledge of what the biological and social sciences have since learned about what they were the first to call the moral sense…
***
Ma dove reperiamo le evidenze sull’esistenza del senso morale?
Essenzialmente osservando i comportamenti dell’uomo…
… Much of what we know about the moral senses has to be inferred from how people behave. For example: We observe somebody helping somebody else. Is the explanation a desire for a reward, hope for a reciprocal favor, or genuine compassion for the other fellow? The best one can do is to try to make a plausible inference from the facts…
Esistono regole universali che unificano tutte le culture…
… how did it happen that in the West people were induced to believe that our moral sentiments should extend to many, perhaps all, people, and not just to family, close relatives, and ethnic kin?…
La morale è dentro di noi. Va riabilitata allora la connessione tra carattere e morale…
… To anticipate and oversimplify the conclusion, it is that an older view of human nature than is now current in the human sciences and moral philosophy is the correct view…
Esiste nell’uomo una tensione verso il bene che va accudita e sviluppata…
… Beneath our wars, crimes, envies, fanaticisms, persecutions, snobberies, and adulteries; beneath, that is to say, all of those human traits that might be said to constitute our original sin, there is a desire not only for praise but for praiseworthiness, for fair dealings as well as for good deals, for honor as well as for advantage….
Leggi il giornale e cosa concludi? Che l’uomo è cattivo!…
… A person who contemplates this endless litany of tragedy and misery would be pardoned for concluding that man is at best a selfish and aggressive animal…
Ma se il male fa notizia è per due ragioni: perché è raro e perché sconvolge il nostro animo…
… But before drawing so bleak a conclusion from his daily newspaper, the reader should ask himself why bloodletting and savagery are news. There are two answers. The first is that they are unusual… The second reason that misery is news is because it is shocking…
Ci sconvolge perché abbiamo un senso morale…
… The argument of this book is that people have a natural moral sense, a sense that is formed out of the interaction of their innate dispositions with their earliest familial experiences. To different degrees among different people, but to some important degree in almost all people, that moral sense shapes human behavior and the judgments people make of the behavior of others…
***
Un tempo l’esistenza di una morale naturale veniva data per scontata…
… At one time, the view that our sense of morality shaped our behavior and judgments was widely held among philosophers…
Aristotele, Tommaso, Smith
La modernità ha rotto con questa tradizione…
… Modern philosophy, with some exceptions, represents a fundamental break with that tradition…
Marx
… Marxism as generally received (and, with some exceptions, as Marx himself wrote it) is a relentlessly materialistic doctrine in which morality, religion, and philosophy have no independent meaning…
I positivisti, la fallacia naturalistica e il necessario soggettivismo morale. A. J. Ayer
… Analytical philosophers took seriously the argument that “values” could not be derived from “facts,” and tended to relegate moral judgments to the realm of personal preferences…
Esistenzialismo
… Existentialists such as Jean-Paul Sartre argued that man must choose his values, but provided little guidance for making that choice….
Pragmatismo
… Richard Rorty, perhaps the most important philosophical writer in present-day America, denies that there is anything like a “core self” or an inherently human quality,…
Freud: solo istinti, nessuna moralità…
… it seems clear that Freudianism was popularly understood as meaning that people have instincts, especially sexual and aggressive ones, and not moral senses; morality, to the extent people acquire any, is chiefly the result of learning to repress those instincts…
Antropologia culturale…
… Ruth Benedict’s best-selling book Patterns of Culture was read to mean that all ways of life were equally valid….
In sintesi: tutto è permesso, dio è morto, l’uomo non ha natura, è una tabula rasa da modellare.
***
due errori quando si parla di cultura: o la cultura è tutto o non è niente…
… Two errors arise in attempting to understand the human condition. One is to assume that culture is everything, the other to assume that it is nothing. In the first case there would be no natural moral sense—if culture is everything, then nature is nothing. In the second, the moral sense would speak to us far more clearly than it does…
Quando la cultura è tutto allora l’educazione diventa una semplice esposizione di valori tra i quali il discente sceglie…
… The “values clarification” approach to moral education that began in the late 1960s warned teachers to avoid “moralizing, criticizing, giving values, or evaluating.” They were especially to avoid “all hints of ‘good’ or ‘right’ or ‘acceptable.’”…
E se scegli di copiare all’esame?…
… There is no evidence that this bit of pedagogical idiocy had any direct effect on the beliefs of children,9 but it may have had an indirect effect on their actions. If a child cheated on an exam, did the teacher respond by helping the student “clarify” the “value” he attached to honesty and dishonesty?…
Non ci sono più contromisure, il relativista è all’angolo.
Una situazione chiaramente in contrasto col buon senso.
Dietro il relativismo c’è lo slogan ossessivo “non giudicare”…
… In my classes, college students asked to judge a distant people, practice, or event will warn one another and me not to be “judgmental” or to “impose your values on other people.”…
Sii tollerante e rispetta la libertà altrui.
Quando si cerca di difendere questa posizione si ripiega di solito su argomenti utilitaristici ma l’insincerità di questa difesa è palese…
… attempt to construct intellectual defenses of these notions, defenses typically based on utility: for example, society is better off if everybody behaves that way. Most people, however, do not act fairly or sympathetically because they have decided that “society” (whatever that is) will be better off as a consequence… The feelings on which people act are often superior to the arguments that they employ…
I relativisti, molto semplicemente, vivono in un mondo che consente loro di essere tali…
… College students, like Professor Rorty, rarely have to cope with an atrocity or give a reason for condemning those they learn of. To them, the perils of accepting cultural relativism are purely hypothetical…
Parlando di criminalità tutti i limiti del relativismo vengono a galla…
… Consider the problem of rising crime rates. Having thought about the matter for many years, I can find no complete explanation for the worldwide increase in crime rates that does not assign an important role to a profound cultural shift in the strength of either social constraints or internal conscience or both… The moral relativism of the modern age has probably contributed to the increase in crime rates, especially the increases that occur during prosperous times. It has done so by replacing the belief in personal responsibility with the notion of social causation and by supplying to those marginal persons at risk for crime a justification for doing what they might have done anyway…
Persino i criminali – una parte minoritaria della società – hanno un senso morale…
… Even criminals believe in morality, at least as they grow older, David Farrington and Donald West have followed a group of working-class London males from early childhood well past the age of thirty…
Tesi: il relativismo è un’ipocrisia, un lusso che chi vive nella bambagia puo’ permettersi di sfoggiare…
… we have a moral sense, most people instinctively rely on it even if intellectuals deny it, but it is not always and in every aspect of life strong enough to withstand a pervasive and sustained attack…
Attenzione: dire che abbiamo una moralità innata non significa aderire alla teoria del “buon selvaggio”…
… To say that people have a moral sense is not the same thing as saying that they are innately good. A moral sense must compete with other senses that are natural to humans—the desire to survive, acquire possessions, indulge in sex, or accumulate power—in short, with self-interest narrowly defined….
***
Molti di noi ubbidiscono alla legge e lo fanno non solo per la paura di ripercussioni. Perché?
Chiediamoci allora come nasce un ordine sociale?
Ci sono due ipotesi.
La prima postula una soluzione razionale: l’uomo è intelligente e si organizza attraverso un piano (contratto sociale)…
… The first is rationalistic and individualistic: order exists because people, horrified by the anarchy of the natural world, find some rule or convention that can keep them from being part of an endless war of all against all. Thomas Hobbes argued that government is created because “every man is enemy to every man,” driven by a desire for gain, for safety…
Seconda ipotesi: abbiamo un senso del dovere innato
… The second explanation is normative and communal: order exists because a system of beliefs and sentiments held by members of a society sets limits to what those members can do. Emile Durkheim believed that neither governments nor markets alone could produce order…
Chi ha ragione? Nessuno. O meglio, entrambi. Esiste sia un piano razionale che un senso del dovere.

Il vegetariano che ammazzava animali di nascosto

Conoscete Claudio Bertonatti?
E’ un vegetariano che recentemente ha lanciato un allarme:
… he warns that eating vegetables doesn’t prevent the death of animals….
La verdura uccide gli animali. Molti.
Uccellini e agricoltura
… I noticed that in the fields of agricultural crops there were no birds, and the few that were there were being persecuted…
Chi ama gli animali non dovrebbe distinguere tra domestici e selvatici
… As a vegetarian, I was helping to prevent the death and suffering of domestic animals, but not of wild species…
I meccanismi della natura sono complessi: animale mangia animale
… From the moment that humans began to raise cattle and adopt agriculture we generated an impact. There is no animal species whose survival doesn’t result in the death of other animals, whether directly or indirectly…
Agricoltura e deforestazione
… Wheat, rice, corn. Most vegans eat these things. The first impact of mass cultivation is deforestation: we force nature out to make room for crops. In Argentina, they set fire to the jungle, burning nests with flamethrowers. Then they must defend the sown land from the birds who come to feed; many landowners do this by scattering poisoned grains. After that, the wild herbivores come looking for the first shoots, so the landowners put up electric fences or hunt the animals down with guns… The land is fumigated to combat fungi, insects and other plants…
L’agricoltura chiede spazio a molti animali che si spostano altrove, ma l’hotel è pieno e quindi…
… The animals that have been driven out move on to other areas which already support animals: the hotel is fully booked. So, the animals go to neighbouring crop fields and another wave of impacts is generated…
Al contrario, l’allevamento fa fiorire la vita
… By contrast, he says, in fields dedicated to livestock there are more species of other animals… There are lots of wild grasslands in Argentina. You can go for a walk there and find everything: amphibians, reptiles, birds…
Certo: buona parte dell’agricoltura esiste per nutrire le bestie allevate. E qui siamo punto e a capo.
Quando le cose sono tanto incasinate distinguere tra buoni e cattivi è dura…
… if you eat meat, you kill animals, but you also kill them by eating plants. A lot of people who care about environmental issues look for good guys and bad guys, but it’s not like that…
Pensate al danno che le miniere e l’estrazione dei metalli arreca a molte specie animali. Eppure gli animalisti usano senza sensi di colpa i computer che impiegano proprio quei metalli…
… if you eat meat, you kill animals, but you also kill them by eating plants. A lot of people who care about environmental issues look for good guys and bad guys, but it’s not like that…
***
Qual è una posizione sensata?
L’impatto zero è impossibile.
Se tutti diventassimo vegani sarebbe una tragedia…
… if the whole human race suddenly became vegan, it would be a tragedy…
Non resta che guardare alla biodiversità: avere cura dell’ambiente nel suo complesso senza fissarsi su questioni specifiche…
… What I find dangerous is that you spend all your energy trying to save the black cat, while knowing nothing about the environment, because maybe you’re wasting your energy; maybe your energy would have a greater impact elsewhere. It’s important to have a broad vision…

Qualche distinguo sulla politica delle sanzioni economiche

Una strategia di politica estera spesso utilizzata contro i Paesi ostili consiste nel varare sanzioni economiche.
Funziona?
Daniel Drezner è la persona ideale a cui chiedere chiedere.
***
Secondo lo studioso si deve andare oltre la logica del funziona/non funziona.
Funzionano meglio con gli alleati che con gli avversari...
... sanctions are far more likely to work with allies than adversaries...
Alcuni ritengono che per funzionare debbano essere adottate rapidamente e con certezza...
... lobbies in favor of harder and faster sanctions, because “there is a better chance to avoid military escalation if sanctions are deployed with maximum impact.”...
Sbagliato: la minaccia di sanzioni funziona meglio delle sanzioni stesse. Bisogna quindi sfruttare al meglio questo fatto, garantirsi i tempi della minaccia e i margini per l’escalation...
... it underestimates the ways in which the threat of sanctions can be more powerful than their implementation. As with any bargaining situation, it is more efficient for the target and sender to agree to a deal before any punishments are inflicted... My own research suggests that sanctions are far more likely to work before they are implemented rather than after...
Altra tesi diffusa su sanzioni e coalizioni...
... “a large coalition of sender countries does not make a sanctions episode more likely to succeed.”...
Le sanzioni che dipendono da una coalizione non funzionerebbero.
Anche qui è il caso di fare dei distinguo. In altri termini, le coalizioni costruite ad hoc per sanzionare hanno scarso successo, è vero, ma lo stesso non può dirsi per le coalizioni istituzionali...
... Sanctions coalitions that have an institutional imprimatur are far more likely to succeed, while ad hoc coalitions of the willing are not... If the UN Security Council or the Financial Action Task Force endorse sanctions, however, targets recognize that the likelihood of the coalition cracking goes down...
Qualcuno sostiene addirittura che le sanzioni inflitte alle dittature finiscono per rafforzarle, la gente si stringe intorno al dittatore...
... A bigger problem with Hufbauer’s argument is his claim that autocratic regimes make for tougher targets...
Può essere vero ma anche qui bisogna precisare. Chiediamoci: la società è con loro? Si tratta di poteri "istituzionali" e accettati oppure di autocrati che dominano con la forza il loro popolo? ...
... Jessica Weeks’ typology of non-democratic states is useful here: authoritarians with powerful civilian audiences (think China or Iran) and personalist strongmen without powerful domestic audiences (think Putin in Russia)...
Il dittatore con appoggi sociali non vuole rischiare...
... Weeks’s cogent argument is that civilian authoritarian regimes are about as risk-averse in their foreign policies as democracies. Even if their civilian audience is narrower than in democratic countries, it is equally risk-averse. Strongmen, by contrast, are far more likely to pursue risky and adventurous foreign policies, even if the odds of victory don’t look all that great...
Un conto è l'Iran, un conto è la Russia...
... we would expect sanctions against Iran to be more successful than sanctions against Russia...
La dittatura russa è carismatica, quella iraniana istituzionale, ovvero ben radicata nella società...
... Iran’s Islamist regime is far more institutionalized than Putin’s more charismatic form of leadership... Hassan Rouhani had publicly acknowledged that the effect of sanctions on the Iranian economy was severe and required quick negotiations to settle the nuclear question...
Un buon argomento contro le sanzioni sono i costi occulti delle sanzioni per chi le infligge...
... Economic sanctions and black market activity go together. By punishing ordinary market activity, sanctions give entrepreneurs a strong incentive to take the criminal route– and they usually earn higher-than-usual profits in the bargain...
Mercato nero, contrabbando e commerci di frodo sono destinati a fiorire insieme alle mafie internazionali, specie nei paesi confinanti...
...As Peter Andreas has demonstrated, trade sanctions encourage the creation of organized crime syndicates and transnational smuggling networks...
Non solo: la corruzione è destinata a perdurare ben oltre il periodo di vigore delle sanzioni...
... The corruption has a path dependent quality, persisting long after sanctions have been lifted...
Le evidenza non lasciano spazio a dubbi...
... For example, according to Transparency International’s 2013 Corruption Perceptions Index, eight of the ten most corrupt countries in the world were either subject to trade sanctions in the 1990’ s, or bordered those countries...

Cornucopia infinita

Cosa rende unica la nostra epoca?
Probabilmente la comunicazione: tutti possono parlare con tutti. Non era mai successo.
Ma anche la ricchezza strabordante.  Nelle parole di Robin Hanson....
... I also suspect our era is uniquely rich, in terms of thinking-talking folks having a median income so far above their subsistence levels... Today median world income is now roughly five times subsistence level and rising...
Per molti la benedizione non potrà continuare a lungo: esistono dei limiti fisici all'arricchimento...
... Wages have risen because economic growth rates have outpaced feasible rates of growing well-trained people. But current growth rates simply cannot continue at familiar levels for ten thousand more years. We'll eventually learn everything worth knowing about how to arrange atoms, and growth in available atoms will be limited by the speed of light...
Una questione di atomi e velocità della luce, quindi.
***
Ma c'è chi la pensa diversamente. Per Bryan Caplan non ci sono limiti alla crescita economica che potenzialmente è eterna.
Tanto per capirsi: pensate solo alle potenzialità di un bene come il simulatore di realtà virtuali...
... I'm baffled. You don't have to be a sci-fi guy to think that in the next century we'll get working virtual reality. And once we have that, why couldn't economic growth of 1% (or 10%) continue forever in simulations? In the real world, we can't all be emperor of an infinite universe. But I don't see why every one of us couldn't preside over our own simulated utopias?...
Tutti possiamo diventare padroni assoluti di interi universi.
Detto in maniera più istituzionale: la crescita economica concerne i valori, non gli oggetti.
E’ l’interiorità che conta, non la materia
... As for all this talk of atoms: Economics is about value, not matter. As long as people regard vivid virtual goods as acceptable substitutes for actual goods, how can the scarcity of atoms stop everyone from having everything he desires?...
Per questo la potenziale cornucopia a disposizione degli uomini non conosce fine.
***
Facciamo l'esempio della classica obiezione, quella per cui non abbiamo atomi a sufficienza per crescere in eterno...
... There are roughly 1057 atoms in our solar system, and about 1070 atoms in our galaxy, which holds most of the mass within a million light years. So even if we had access to all the matter within a million light years, to grow by a factor of 10200, each atom would on average have to support an economy equivalent to 10140 people at today’s standard of living, or one person with a standard of living 10140 times higher, or some mix of these...
Un'obiezione che non regge al semplice esperimento mentale del simulatore...
... Suppose the universe contains one person and one really good virtual reality machine. In this virtual reality, the universe's sole inhabitant is a god. Whatever he thinks, happens. Question for Robin: As long as this person regards virtual reality as a good substitute for actual reality, why shouldn't we say that his standard of living is not just 10140 times greater than ours, but infinitely greater than ours?...
Non occorre sfruttare più atomi per produrre più ricchezza.
In piccolo lo vediamo bene con la pubblicità: si raddoppia di valore un bene senza spostare un atomo. La pubblicità crea valore agendo sull’interiorità delle persone. Anche per questo motivo gli ambientalisti dovrebbero venerare questo mezzo che ci arricchisce a consumo zero.
