Contro la discussione politica SAGGIO

POLITICAL PARTICIPATION CORRUPTS - Against Democracy by Jason Brennan
Come educare un popolo alla democrazia?
Il pensiero di molti: facendolo partecipare.
Il pensiero innanzitutto di John Stuart Mill...
... Mill hoped that getting citizens involved in politics would induce them to take on broader perspectives, empathize with one another more, and develop a stronger concern for the common good. He hoped political engagement would develop their critical thinking skills and increase their knowledge...
Si chiama "education argument" e si snoda così...
... 1.Civic and political activity requires citizens to take a broad view of others’ interests, and search for ways to promote the common good. This requires long-term thinking as well as engagement with moral, philosophical, and social scientific issues. 2.If so, then civic and political activity will tend to improve citizens’ virtue and make them better informed. 3.Therefore, civic and political activity will tend to improve citizens’ virtue and make them better informed...
Convinse persino Tocqueville...
... Nineteenth-century historian and author of Democracy in America Alexis de Tocqueville also advanced it, though with many reservations...
Tuattavia, è più probabile che la partecipazione democratica ci corrompa eticamente piuttosto che ci educhi. Vediamo perchè.
***
La tesi di Mill va verificato sul campo...
... The education argument is popular among philosophers and theorists, but is not really a philosophical argument... Instead, the education argument is a social scientific one... Whether it in fact produces those results is something we can, in principle, test using social scientific methods... One must provide strong empirical evidence that when citizens participate more, they will tend to take a broad view of others’ interests...
Ma nasce un problema: cosa intendere per partecipazione?...
... what forms of participation are supposed to ennoble and educate...
E su chi ricade l'onere della prova?...
... Now suppose we don’t know how to measure what participation does to us, and so we just don’t know whether Mill is right or wrong. In that case, we should still not accept the education argument. Just as we should not accept, without proper evidence, that the paleo diet makes us healthier...

Nel verificare dobbiamo fare attenzione: chi partecipa potrebbe essere più informato perché più appassionato e non per il fatto che partecipa...
... Chapter 2 demonstrated that people who are more interested in politics are both more likely to be well informed and more likely to participate. That evidence implied that voters know more not because they vote...
Analogia...
... we already have strong evidence of a selection effect. High school students who say they intend to major in philosophy have higher average SAT scores than those who are drawn to any other intended major, except physics...
Un dato cruciale: dove il voto è obbligatorio la preparazione del cittadino cresce?...
... Some governments force citizens to vote, and this allows us to test whether getting citizens to vote causes them to acquire greater levels of knowledge...
No...
... The test results are negative. Political scientist Sarah Birch, in her comprehensive book Full Participation, reviews nearly every published paper examining whether compulsory voting improves voters’ knowledge. She concludes that it does not... In a related work, political scientist Annabelle Lever recently reviewed the empirical studies on compulsory voting, and concluded that it had “no noticeable effect on political knowledge or interest [or] electoral outcomes.”...

Obiezione: partecipare non equivale a votare ma a discutere...
... Many advocates of the education argument will be nonplussed by these results. They would say that for participation to educate and enlighten us, it’s not enough to vote. We need to talk...
Apologia della democrazia deliberativa...
... Hélène Landemore says, “Deliberation is supposed to … [e]nlarge the pools of ideas and information, … [w]eed out the good arguments from the bad, … [and lead] to a consensus on the ‘better’ or more ‘reasonable’ solution.”10 Bernard Manin, Elly Stein, and Jane Mansbridge contend that democratic deliberation is a process of training and education.11 Joshua Cohen claims “the need to advance reasons that persuade others will help to shape the motivations that people bring to the deliberative procedure.”... Habermas says deliberators should observe the following rules: •Speakers must be consistent; they must not contradict themselves. •Speakers must treat like cases alike. •Speakers should use terms and language in a consistent way so as to make sure they are all referring to the same things. (There should be no equivocating or switching definitions in ways that would interfere with communication.) •Speakers must be sincere; they must assert only what they believe. •Speakers must provide reasons for introducing a subject or topic into the discussion. •Everyone who is competent to speak should be allowed into the discussion. •Speakers should be allowed to discuss any topic, assert whatever they like, and express any needs—so long as they are sincere. •No one may coerce or manipulate another speaker...
Gli apologeti avevano in mente una discussione ideale...
... If people are sincere, rational, offer reasons for their views, give every voice proper respect, and so forth, then of course deliberation will educate people. If people were to follow Habermas’s or Cohen’s rules, then they would deliberate the way vulcans would deliberate. Of course deliberation would educate and enlighten them...
Ma si tratta di una fantasia spericolata...
... But as philosopher Michael Huemer comments, deliberative democracy so described looks like fantasy: “If there is one thing that stands out when one reads philosophical descriptions of deliberative democracy, it is how far these descriptions fall from reality...
Innanzitutto, giustificare le proprie proposte non è mai stato richiesto da nessun sistema democratico. Come fare, del resto?
Nei fatti, la discussione di Habermas si traduce in una sequela di appelli retorici e slogan urlati...
... Habermas and Cohen say that citizens must advance reasons for their proposals....But in actual democracies and deliberation, no one is literally required to state reasons for their policy proposals... What matters are rhetoric, sex appeal, and promoting the team...
Di fatto, a dominare la discussione politica è la caterva di bias cognitivi che ci affliggono...
... As I discussed in chapter 2, political psychology shows that most of us are much more like hooligans than like vulcans. We suffer from a number of biases, including: Confirmation bias: We tend to accept evidence that supports our preexisting views. Disconfirmation bias: We tend to reject or ignore evidence that disconfirms our preexisting views. Motivated reasoning: We have preferences over what we believe, and tend to arrive at and maintain beliefs we find comforting or pleasing, or whatever beliefs we prefer to have. Intergroup bias: We tend to form coalitions and groups. We tend to demonize members of other groups, but are highly forgiving and charitable toward members of our own groups. We go along with whatever our group thinks and oppose what other groups think. Availability bias: The easier it is for us to think of something, the more common we think that thing is. The easier it is for us to think of an event occurring, the more significant we assume the consequences will be. We are thus terrible at statistical reasoning. Prior attitude effect: When we care strongly about an issue, we evaluate arguments about the issue in a more polarized way. Peer pressure and authority: People tend to be influenced irrationally by perceived authority, social pressure, and consensus...

Veniamo ai  fatti: misuriamo i benefici della discussione. Entità? Minima o inesistente...
... In a comprehensive survey of all the extant (as of 2003) empirical research on democratic deliberation, political scientist Tali Mendelberg remarks that the “empirical evidence for the benefits that deliberative theorists expect” is “thin or non-existent.”19 In her survey, Mendelberg finds: •Deliberation sometimes facilitates cooperation among individuals in social dilemmas, but it undermines cooperation among groups. When people self-identify as members of a group, including as members of political groups, deliberation tends to make things worse, not better.20 (Remember that in the real world, people tend to self-identify as members of a political group.) •When groups are of different sizes, deliberation tends to exacerbate conflict rather then mediate it.21 (Note that in realistic circumstances, political groups tend to be different sizes.) •Deliberation does tend to make people more aware of others’ interests. Nevertheless, other empirical work shows that if groups simply state their preferences without any discussion, this is just as effective as stating their preferences with discussion.22 So deliberation per se isn’t itself helpful in this case. •Status seeking drives much of the discussion. Instead of debating the facts, people try to win positions of influence and power over others.23•Ideological minorities have disproportionate influence, and much of this influence can be attributed to groups’ “social appeal.”24 •High-status individuals talk more, are perceived as more accurate and credible, and have more influence, regardless of whether the high-status individuals actually know more.25 •During deliberation, people use language in biased and manipulative ways. They switch, for example, between concrete and abstract language in order to create the appearance that their side is essentially good (and any badness is accidental) while the other side is essentially bad (and any goodness is accidental). If I describe my friend as kind, this abstract language suggests that they will regularly engage in kind behavior. If I say that my enemy donated some money to Oxfam, this concrete language leaves open the question of whether this kind of behavior matches my enemy’s character and could be expected again.26 •Even when prodded by moderators to discuss controversial matters, groups tend to avoid conflict, focusing instead on mutually accepted beliefs and attitudes.27 •When a discussant mentions commonly held information or beliefs, this tends to make them seem smarter and more authoritative to others, and thus tends to increase their influence... Deliberation works best on “matters of objective truth”... During “other times”—when citizens debate morals, justice, or social scientific theories meant to evaluate those facts—“deliberation is likely to fail.”...
Per Mandelberg domina la razionalizzazione...
... the use of reasoned argument to reinforce prior sentiment is a widespread phenomenon that poses a significant challenge to deliberative expectations...
Altri studi: discutere polarizza e fomenta il dissenso...
... Rather than causing consensus, public deliberation might cause disagreement along with the formation of in-groups and out-groups.43 It can even lead to violence...
Discutere scatena isterie ed emotività
… Deliberation over sensitive matters—such as pornography laws—frequently leads to “hysteria” and “emotionalism,”…
Discutere rende nichilisti
… Deliberation frequently causes deliberators to doubt there is a correct position at all. This leads to moral or political skepticism or nihilism…
Discutere rende agnostici
… Deliberation often makes citizens apathetic and agnostic about politics,…
La discussione ci rende più manipolabili
… During deliberation, citizens frequently change their preferences and reach consensus only because they are manipulated by powerful special interests…
La discussione è cordiale quando evita le questioni spinose
… Consensus often occurs only because citizens purposefully avoid controversial topics…
***
I fautori della democrazia deliberativa, forse perché consapevoli delle debolezze della loro proposta, hanno elaborato metodi di discussione ad hoc. Esempio, il polling...
... Some deliberative democrats advocate replacing or at least supplementing mass voting with “deliberative polling.” In a deliberative poll, one brings together, say, a thousand citizens to deliberate about a given topic. The citizens are selected at random, although the poll’s organizers try to ensure that the demographics of the deliberative body are similar to those of the community or nation as a whole. The organizers give the deliberators relevant informational sources, such as news articles, social scientific papers, and philosophical arguments for various sides. A moderator helps spur participants to deliberate and do so properly. The moderator tries to ensure that people stick to the topics at hand and that no one dominates the conversation. There is some evidence that this kind of moderated deliberation can work, at least in the laboratory and even in some real-world scenarios...
Attendiamo con fiducia le prove empiriche a sostegno finora mancate, altrimenti...
... In the end, I am an instrumentalist about the choice between democracy and epistocracy. If democracy with deliberative polling (with whatever abuses and flaws it suffers) turns out to produce better results than the best form of epistocracy (with whatever abuses and flaws it suffers), then I’ll advocate democracy with deliberative polling...
***
La conclusione consolatoria di alcuni: il metodo deliberativo non funziona ma nemmeno fa danni...
... It would be tempting in that case to conclude that deliberation is pointless and ineffective, but at least not harmful...
Tuttavia, una conclusione neutrale è una conclusione negativa. Vediamo perché.
Chi discute e cade nel bias cognitivo (per esempio non rettifica le sue posizioni originarie a fronte di validi argomenti che gli vengono presentati) è, dal punto di vista epistemologico, in una situazione peggiore di chi non discute…
… What is rational for you to believe or not depends on the evidence available to you. Imagine a child has led a sheltered life, with no exposure to history, geology, biology, physics, or cosmology. They believe, on the basis of their young Earth creationist parents’ testimony, that the universe is six thousand years old and that all animals were created six thousand years ago. But suppose this child then takes sixteen years of classes in history, geology, biology, physics, and cosmology. Along the way, they get to sequence DNA, re-create Gregor Mendel’s pea experiment, handle fossils, and the like. After sixteen years of intense study, though, suppose they continue to believe the world is six thousand years old and that all animals were created as they currently are. In this case, from an epistemological standpoint, they got worse. After all, they encountered an overwhelming amount of evidence confirming evolution and disconfirming young Earth creationism. They should have changed their mind, but didn’t….
Poiché chi discute di politica cade ripetutamente nei vari bias sopra elencati, possiamo concludere che la discussione politica ci rende persone peggiori
… when deliberation has no effect on citizens’ beliefs or their degree of credence in their beliefs, we should generally interpret this as showing that deliberation made them worse, from an epistemic viewpoint…
E’ questo, per un difensore della discussione deliberativa, è ancora più vero: quelli che abbiamo chiamato doveri epistemici sono per lui doveri etici.
***
Come reagisce il “deliberazionista” di fronte alla confutazione della sua teoria? E’ perplesso, prende tempo, introduce ipotesi ad hoc, dice che c’è “partecipazione” e “partecipazione”
… One might expect that most deliberative democrats would advocate deliberation cautiously or with reservations, only in those cases where we had solid evidence it works.48 On the contrary, deliberative democrats tend to be nonplussed by the empirical results described above… They tend to assume the benefits of deliberation will be revealed in due time… people aren’t deliberating the right way…
Ma soprattutto conclude che la gente discute in modo scorretto
… Deliberative democrats can rightly assert that the research hasn’t falsified their views, because people aren’t deliberating properly…
Logicamente questa posizione tiene. Ma praticamente è fallimentare.
E’ come quando i comunisti, di fronte all’ennesimo fallimento del socialismo reale, dicono vanamente: “ma quello non è socialismo”.
E’ come quando i capitalisti, di fronte a Bernard Madoff, dicono: “ma quello non è capitalismo”.
Pensate solo se il Papa, di fronte alla piaga dei preti pedofili dicesse: “il loro comportamento comunque non è cattolico, quindi la Chiesa Cattolica è immune da tutto”.
Vero, ma la Chiesa reale produce di fatto tutto cio’. Allo stesso modo ai deliberazionisti diciamo: vero, ma di fatto la discussione politica produce tutto il marasma che abbiamo visto…
… If they say, “Sure, actual deliberation messes people up, but proper deliberation would improve their character and knowledge,” that’s not much different from stating, “Sure, actual fraternities mess men up, but proper fraternities would improve their character and scholarship.”…
***
Conclusione: meglio l’ignoranza che il sapere deforme. Meglio non peccare in assenza di tentazioni che peccare indotti in tentazione…
… Sometimes it is better for a person’s epistemic character if they remain ignorant and apathetic…
Meglio allora non interessarsi alla politica: ci rende irrazionali facendo di noi persone peggiori… 
… For these reasons, we have strong presumptive grounds against encouraging more and more citizens to participate in politics, spend time thinking about politics, watch political news, or engage in political deliberation…

Il burrascoso matrimonio tra scienza e cristianità

Science and Christianity in Pulpit and Pew by Ronald L. Numbers
In che relazione stanno storicamente scienza e fede.
La posizione ortodossa: conflitto perenne…
… Prominent nineteenth-century scholars such as Andrew Dickson White (1832-1gi8) and John William Draper (1811-1882) assured their readers that science and religion existed in a state of perpetual opposition…
Secondo questa vulgata il “primo aggressore” è la religione…
… Draper identified the primary aggressor as the Roman Catholic Church, whose “mortal animosity” toward science had left its hands “steeped in blood.” Despite the efforts of less bellicose historians during the past quarter century or so to craft a more accurate and less prejudicial narrative, the notion of warfare between science and religion continues to thrive, particularly at both ends of the politicotheological spectrum…
Da allora è passata molta acqua sotto i ponti ma Jon H. Roberts ha definito la visione ortodossa “un’ idea dura a morire”.
I potenti simboli dell’eterno conflitto…
… Everyone knows about the trials of Galileo Galilei (1564-1642) in seventeenth-century Italy and of John Thomas Scopes (1900-1970) in twentieth-century Tennessee…
In realtà il conflitto attraversa le diverse confessioni religiose, e questo fatto complica le cose…
… Many of the bitterest conflicts over science have taken place within religious communities, where differences easily mutate into heresies…
Una notizia fastidiosa per gli ortodossi: i religiosi sono stati da sempre in prima fila nello studio della natura…
… Proponents of the warfare thesis have typically failed to recognize that religious people and institutions have often cultivated the study of nature. During the Middle Ages, as David C. Lindberg and other medieval historians have convincingly shown, churchmen were the most ardent supporters of natural philosophy and natural history…
Un amore duraturo: quello tra astronomia e Chiesa Cattolica. Lo storico di Berkley John L. Heilbron…
… “the Roman Catholic church gave more financial and social support to the study of astronomy for over six centuries, from the recovery of ancient learning during the late Middle Ages into the Enlightenment, than any other, and, probably, all other, institutions…
***
C’è poi l’estremo opposto: scienza frutto del cristianesimo…
… Another popular “just-so” story about science and Christianity portrays the latter-or one of its subdivisions, such as Protestantism or Puritanism-as the fountainhead of modern science…
L’esempio della vulgata consolatoria di Whitehead
… Alfred North Whitehead (1861-1947), in Science and the Modern World, argued that Christianity, by insisting that nature behaves in a regular and orderly fashion, allowed science to develop. Understandably, many Christians have found this self-congratulatory view more attractive than the narrative of conflict…
Ma per arrivare a tanto si devono minimizzare molti contributi difficili da negare…
… it ignores or minimizes the contributions of ancient Greeks and medieval Muslims-it, too, refuses to succumb to the death it deserves…
Un altro apologeta…
… The sociologist Rodney Stark at Baylor University, a Southern Baptist institution, is only the latest in a long line of Christian apologists to insist that “Christian theology was essential for the rise of science…
***
C’è infine una terza posizione: capire è difficile. Tutto è più sfumato e le distinzioni attraversano campi di solito visti come compatti…
… historians of science and religion have turned increasingly to what has been called the complexity thesis, the notion that the record of the past is too chaotic to reveal a simple pattern…
Una figura chiave di questo partito…
… No one has advanced this view more successfully than John Hedley Brooke, who has identified a wide range of interactions between scientific and religious impulses. At times, religion has stimulated the investigation of nature; on other occasions it has inhibited it…
Una posizione del genere non solleva polemiche, forse per questo è poco nota…
… However, because this view tends to strip the subject of its polemical value, it has found comparatively little favor with present-day cultural warriors fighting one another in the trenches…
***
Un esempio per comprendere questa terza posizione: la ricezione di Darwin da parte del mondo cristiano.
L’esempio di due posizione estremiste: solo i calvinisti lo capirono. Oppure: solo gli atei lo compresero accettandolo…
… In The Post-Darwinian Controversies (1979) a young James R. Moore underscored the importance of theology in determining individual responses to evolution in Great Britain and North America. He insisted that only “those whose theology was distinctly orthodox”-that is, Calvinist-could swallow Darwinism undiluted. (Contrast this with David L. Hull’s equally hyperbolic claim “that almost all the early proponents of Darwinism were atheistic materialists-or their near relatives.”)… Subsequent studies by Jon H. Roberts, David N. Livingstone, and me have undermined Moore’s sweeping claim…
C’è chi ha visto Darwin come un problema soprattutto per i protestanti
… In a new introduction to his meticulously researched Darwinism and the Divine in America (1988), Roberts argues that “the great majority of American Protestant thinkers who remained committed to orthodox formulations of Christian doctrine actually rejected Darwinism… evolution could not be reconciled with their views of the origin, nature, and `fall’ of man, the nature and basis of moral judgment, and a number of other doctrines-all…
Tuttavia, la verità che emerge è un’altra: la ricezione di Darwin da parte del protestantesimo è stata eterogenea
… Given the theological heterogeneity of Protestantism, it is not surprising to find a range of responses to evolution. But even in the hierarchical Roman Catholic Church, where one might expect relative uniformity, we also find diversity…
Lo stesso dicasi per il mondo cattolico
… In an early essay on “varieties” of Catholic reactions to Darwinism, Harry W. Paul contrasted “the power Catholicism was able to exert against Darwinism in Spain” with its virtual impotence in Italy. Even more telling, however, are the revelations coming out of the recently opened Vatican archives of the Congregation for the Doctrine of the Faith, which hold the records of the old Congregations of the Holy Office and of the Index. In researching their book, Negotiating Darwin: The Vatican Confronts Evolution, 1877-1902 (2006), Mariano Artigas, Thomas F. Glick, and Rafael A. Martinez discovered six instances in which the Vatican dealt with complaints about Catholic evolutionists, with two of the accused coming from Italy, two from England, and one each from France and the United States. These complaints resulted in no official condemnation of evolution, though some individual works were proscribed and placed on the Index of Prohibited Books…
L’opposizione, in questo caso, venne dai Gesuiti più che dal Vaticano…
… The strongest opposition to Darwinism came not from the Vatican itself but from La Civilta Cattolica…
Alcuni hanno riscontrato una certa resistenza alle nuove idee nelle organizzazioni più centralizzate, come la CC…
… Glick identified “centralization of power” rather than cultural isolation as the “crucial variable” in determining how various countries responded to evolution. In contrast to the largely Protestant United States, where church and state remained constitutionally separate and Protestant sects competed openly, the more centrally controlled Latin American countries presented an environment relatively inhospitable to new ideas…
David Livingstone mette in guardia dalle semplificazioni: anche tra i calvinisti, per esempio, gli oppositori a Darwin non mancarono…
… even among Calvinists, responses to evolution varied markedly from one locale to another. Irish Calvinists in Belfast, for instance, strongly resisted Darwinism, in large part, it seems, because of John Tyndall’s (1820-1893) infamous 1874 presidential address to the British Association for the Advancement of … Calvinists elsewhere had also been influenced by local circumstances…
***
Traiamo un piccolo insegnamento da questo excursus…
… Historians, he wisely urged, should quit speaking “of the encounter between science and religion in a generalized, decontextualized, delocalized way…
Tutto va approfondito e contestualizzato. Non esistono regole generali facili da enunciare.
Sull’accoglimento delle idee darwiniane oggi fioccano molti studi su base nazionale ma ancora nessuna regola generale in vista…
… David L. Hull’s decades-old observation that no one had yet demonstrated a correlation “between the reception of Darwin’s theory around the world and the larger characteristics of these societies,” including their religious cultures, still largely holds.’…
C’è molta varietà anche a livello locale…
… Not only did Darwinism mean different things in different countries, but its meaning varied even within national settings…
Sui darwiniani neozelandesi
… John Stenhouse has drawn attention to the way some New Zealanders drew on Darwinism to justify, in terms of “survival of the fittest,” their harsh treatment of the native Maori. But rivalries among white Anglicans, Methodists, and Presbyterians undermine generalizations about New Zealanders as a whole.” …
A volte l’entusiasmo darwiniano era maldiretto e forse più sviante del suo respingimento.
La ricezione dei marxisti
… Adrian Desmond, perhaps the most influential of this group, has noted that the godless “working classes” and the “lowlife in the medical schools,” eager to create a new social and economic order, found Lamarckian evolution especially attractive…
Manche qui: molte fratture interne e nessuna possibilità di generalizzare…
… James Secord, however, looking primarily at responses to one widely read evolutionary tract, Vestiges of the Natural History of Creation (1844), has argued that the ensuing debates “contributed to fracture lines within the middle class; they were intra- rather than interclass, with a crucially important religious dimension….
Forse conta di più la psicologia che l’economia. C’è chi si è fissato con l’ordine di nascita: i secondogeniti sono darwiniani doc…
… The historian of science Frank J. Sulloway has also downplayed class-based explanations. In a statistical analysis of the dynamics of intellectual revolutions, including the one associated with Darwin, he makes a strong case for paying more attention to psychosocial than to socioeconomic factors… personalities, formed in large part by the order in which they were born into their families and by the ensuing competitive strategies they adopted in dealing with their siblings… later-borns were 4.6 times more likely to support evolution than firstborns…. the focus of the battle over the theory of evolution was within the family, not between families.1714…
Quanto conta la razza per aderire all’evoluzionismo?…
… Historians of evolution have rarely investigated the importance of race and gender, two analytical categories of great importance to social historians… as Eric D. Anderson has shown, African American intellectuals for decades regarded theories of plural human origins more threatening than Darwin’s monogenetic theory… Jeffrey P. Moran found African American elites much more willing than the conservative black clergy to embrace evolution…
Darwin ha sempre costituito un problema per le donne, specie quelle con figli…
… Because of Darwin’s use of sexual selection and the implications that he drew about female inferiority, gender became integral to the evaluation of Darwinism-and problematic for some feminists. However, religious concerns tended to trump gendered ones. As Moran has shown, antievolutionists often spoke in the name of mothers concerned about the irreligious effects of evolution on their children….
Le grandi sacerdotesse anti-darwiniane…
… Among the mothers who spoke for themselves were Ellen G. White (1827-1915), the founding prophetess of Seventh-day Adventism and the godmother of creation science, who traced evolution back to its “satanic origin,” and Aimee Semple McPherson (1890-1944), the flamboyant founder of the International Church of the Foursquare Gospel, who damned evolution in public debate in the early 1L3 0s.16…

Ovunque si guardi l’accettazione di Darwin si presenta differenziata, fissarsi sulla prospettiva generica della religiosità sembra eccessivo e strumentale.
Ecco, questa conclusione puo’ essere generalizzata e dà un’idea corretta del rapporto tra scienza e cristianità.
