Outhéopo

Raffaele Ventura, che è uno che sa addirittura scrutare i segni della fine del mondo nell'epoca della sua riproducibilità tecnica, sta mettendo in piedi un sito sulle teologie future e immaginarie (lui dice "potenziali") e quindi anche sulle passate, con un approccio "ludico", e forse non solo (è tutto da capire). Promette di mescolare realtà e finzione, ma senza ingannare il lettore. Un po' Borges e un po' Gilson, un po' Debray e un po' nuvole di tags, il sito è in linea da poche ore e aggiunge rapidamente contenuti, soprattutto rischia di lanciare qualcosa. Non so cosa. Seguiamolo e vediamo.

Annunci

Per chi fosse nei paraggi

Per chi fosse nei paraggi e fosse interessato, giovedi sarò a Auxerre, invitato dal Dominique Iogna-Prat e Frédéric Gabriel, presso il Centro di Studi Medievali, a discutere con Emanuele Coccia e Sylvain Piron di "Ecclesiologia e potere dottrinale" nel medioevo  (qui il programma). Venerdi invece parteciperò al convegno organizzato da Juhan Toivanen presso l'Istituto Finlandese di Parigi, su "Soggettività e sociabilità" nelle tradizioni politiche medievali (qui il programma). Martedi prossimo sarò ospite di Olivier Boulnois all'EPHE di Parigi (3 maggio, 14h, salle 124), a parlare di: "Dominium – potere, proprietà, dominazione".

I tre giorni in cui Cristo fu morto

Proviamo a fare un esperimento mentale. Immaginiamo che la notte dell’ultima Cena, dopo la consacrazione del pane come corpo di Cristo (come corpo vero, non simbolico, per i cattolici), un apostolo, uno qualsiasi, avesse conservato per sé una parte di quel pane. Immaginiamo anche che dopo la morte di Cristo, qualche ora dopo, durante i giorni neri dello sgomento, della paura e del dubbio, cioè durante i giorni in cui Cristo fu davvero morto, quell’apostolo avesse ripreso il pane sottratto e già consacrato, cioè il corpo di Cristo, e l’avesse mangiato. In quei tre giorni, avrebbe mangiato il corpo di Cristo vivo o il corpo di Cristo morto?
L’esperimento non è blasfemo e la domanda se la sono posta in tanti, e come strumento di conoscenza, tra loro per esempio (san) Tommaso d’Aquino e (il beato) Duns Scoto, che di professione non facevano i santi, ma gli intellettuali. E infatti le loro risposte sono altre domande. Che cos’è un corpo vivo? A quali funzioni vitali corrisponde la vita di un corpo? E perché un cadavere non si decompone istantaneamente? Forse alcuni processi continuano? Che rapporto c’è tra l’anima e l’intelletto e le sue funzioni? Non bisogna forse ridefinire scientificamente meglio la nozione di corpo?
Insomma chi leggesse alcuni dei lavori medievali e moderni sui quei tre giorni in cui Cristo davvero non c’era e sull’eucaristia (e anche Galileo aveva una sua teoria), si troverebbe di fronte a dei veri e propri trattati scientifici, che parlano sì del corpo di Cristo, ma cercando di capire come funziona il nostro. La teologia poneva così domande religiose, certo, ma soprattutto provocava la scienza perché cercasse risposte con i propri mezzi, affinandoli, a questioni e rompicapo che da sola non aveva pensato.
Di esperimenti mentali bizzarri di questo tipo, e usati come tali, (ma non più bizzarri di quelli con cui Einstein, per esempio, cercava una via di comprensione della relatività della nozione di spazio), ce ne sono stati molti, e dalle conseguenze importanti. Perché il roveto ardente del Sinai bruciava e non si consumava? Bruciava e non bruciava? È possibile infrangere addirittura l’impossibilità logica della contraddizione? Ma allora forse se Dio volesse potrebbe far sì che Roma sia stata fondata e non sia stata fondata, nello stesso tempo? Fondata e non fondata, insieme. Se la risposta è affermativa bisogna mettere alla prova la logica, non per dire che la logica non funziona, ma proprio per pensare se possano esistere modelli logici diversi da quelli basati sulla non contraddizione formale. È anche da queste domande che nascono le teorie dei “mondi possibili” e insomma in questo senso la trilogia di Ritorno al futuro e certe curvature di Inception non sarebbero che un’applicazione di quegli antichi dibattiti.
Insomma per i credenti la settimana santa è certamente motivo di meditazione religiosa e esistenziale, ma per tutti gli altri potrebbe essere occasione di riflessione su quanto complessa sia la storia dei rapporti tra saperi, tra ricerca  e credenze e in fondo tra esistenza e conoscenza.

 

Imbattimenti

Ognuno di noi sa che ci sono più cose belle e interessanti di quante ne possiamo cogliere. Ci diciamo che non ci basta il tempo né a volte ci aiutano le abitudini. "Guerra e pace" non l'ho mai letto, anche se so che sarebbe un'esperienza, e credo che morirò senza averlo letto (un peccato), e non ho neppure visto tutta la filmografia di Orson Welles, per non parlare di Antonioni, che mi darebbero invece sicure soddisfazioni (ce la farò). Alcune cose invece riusciamo a farle o vederle, e ci cambiano lo sguardo per sempre, come leggere Machiavelli o Dante, o come la  prima volta a New York, in cui si ha  la sensazione di essere tornati a casa, oppure ancora quando si prova il Jerez (muy seco, muy frio). Ma la maggior parte di questo giacimento di possibilità di bellezza rimane inesplorato, purtroppo, lo sfioriamo appena. Ogni tanto invece ci si imbatte in qualcosa, senza volere, che da quel momento si integra permanentemente con il resto. Per esempio questa canzone, che non avevo mai sentito prima che qualcuno ci si presentasse.

C’è un momento nella vita di ognuno

C'è un momento, nella vita di ognuno, in cui gli slanci della prima giovinezza vengono meno, in cui ci si rende conto, e con serenità, che il mondo è più forte, che le asprezze degli ideali possono essere mitigate, che la disciplina che ci ha naturalmente condotti a esperienze e risultati che un tempo sembravano essenziali viene meno, e quelle stesse esperienze, una volta attraversate sembrano più evanescenti e meno importanti di quanto avessimo creduto. E' in quel momento che una sorta di seconda adolescenza sembra guadagnarsi spazio, che le immagini e le possibilità scartate riprendono consistenza. Alcuni allora cambiano semplicemente modo di vestire, altri riprendono attività che avevano lasciato da parte, sogni infantili o adolescenziali che il percorso della vita aveva reso inattuali, altri ancora ritornano al gioco, nel tentativo di riattivare emozioni e sensazioni che riaprano il percorso della vita. Per alcuni quel momento è davvero l'inizio di una nuova vita, per altri è la primizia di una nuova età. Per altri ancora, come il personaggio seguente, è una roba incomprensibile (ma con finale ballerino esilarante).

Per la contradizion che nol consente

Forse perchè non abito in Italia mi sono perso qualche passaggio. Ricapitoliamo: Berlusconi interviene con la questura perchè pensa che Ruby sia la nipote di Mubarak. A dirglielo non è il sismi, nè il ministero degli esteri, nè l'ambasciatore italiano in Egitto, ma una prostituta brasiliana che lo chiama sul suo cellulare privato nel mezzo di un vertice a Parigi. Berlusconi inoltre è convinto che la nipote di Mubarak sia maggiorenne, anche quando la polizia gli dice di non poterla lasciare andare perchè il giudice intende affidarla a una comunità in quanto minorenne, a meno che non venga affidata a qualcuno di fiducia (in quanto minorenne). Berlusconi manda la Minetti, alla quale viene affidata la minorenne che Berlusconi crede maggiorenne. La persona di fiducia, che dovrebbe tutelare la minorenne, la scarica invece per la strada. Berlusconi infine paga la nipote di Mubarak, con la seguente letterale motivazione: "per evitare che si prostituisca".
Il principio aristotelico di non contraddizione viene sospeso, come in certi esperimenti mentali teologici medievali: il fuoco brucia e non brucia, come l'arbusto della Genesi e Dio può fare che Roma sia stata fondata e non sia stata fondata, insieme.

Sono partite le presidenziali francesi 2012

Con la crisi libica si è aperta la lunga campagna per le presidenziali francesi del 2010. Ed è già ricca di spunti e dibattiti.
La rielezione di Sarkozy è molto problematica e la “maggioranza presidenziale” è in fibrillazione, soprattutto ora che Villepin, ex ministro degli esteri e poi primo ministro durante l’ultima presidenza Chirac, uscito ormai dal partito di Sarkozy, sta annunciando la propria candidatura. E sarà interessante capire come cercherà di imporre la propria agenda al dibattito nazionale e su quali temi alternativi a quelli di Sarkozy batterà.
Fino ad oggi Sarkozy, a corto di risultati evidenti, ha lanciato un dibattito sull’identità nazionale (mai decollato), sulla nuova laicità (ma nessuno sembra averne dato seguito), sulla sicurezza (ma l’espulsione dei rom non ha spostato di un millimetro i sondaggi).
Abbandonata anche la carta dell’innovazione ecologica, che ha caratterizzato il discorso pubblico della prima parte del suo mandato, ora Sarkozy punta sull’assunzione di una nuova leadership nell’Africa mediterranea e su un ruolo importante in Costa d’Avorio, ma le difficoltà libiche rischiano di diventare un boomerang.
Insomma il presidente nel suo non stringente iperattivismo sembra cedere proprio nella capacità di incarnare il ruolo presidenziale. Come dice il grande intellettuale Régis Debray a Le Monde “vedendo De Gaulle si vedeva la Francia stessa, vedendo Gambetta avremmo potuto probabilmente vedere la Repubblica, vedendo Sarkzozy il dramma è che vediamo solo Sarkozy”.
Da destra poi è interessante  il grande lavoro di Marine Le Pen, che con eccezionale capacità retorica e uno spirito mai banale, cerca di “normalizzare” il Fronte Nazionale (come dicevo anche qui). Il che non sarebbe di poco conto, tenendo presente che la Francia ha storicamente due destre, una di origine antifascista che rimonta a De Gaulle e una, appunto il FN, che in una sua parte cospicua si dichiara ancora “petainista”. Il grande successo nei sondaggi di Marine Le Pen si dovrà poi però misurare con le sue idee economiche, proprio in questi giorni rimesse a punto per le presidenziali, che appartengono più al regno degli impossibilia: uscita dall’euro con un nuovo franco di valore pari all’euro e con una svalutazione controllata per far ripartire l’economia; introduzione di dazi doganali; allontanamento dalle norme economiche dell’unione europea.
Il Partito Socialista, che ieri dichiarava tramite Hollande che il prossimo presidente “non sarà che socialista” dal canto suo non ha ancora stabilito, e avrà seri problemi a farlo senza rotture, chi sarà il candidato. La Royal, forte del costume francese della ricandidatura e dei successi nella regione Poitou-Charentes da lei governata, ritiene di essere la candidata prioritaria e Martine Aubry, forte dei successi socialisti legati alla sua presidenza, altrettanto. Nel frattempo si sono fatti vivi lo stesso Hollande e il molto amato Strauss-Kahn.
Inoltre, la campagna presidenziale che si annuncia toccherà tutti i temi e i dossier che stanno a cuore anche a noi, non solo Libia e Mediterraneo, la crescita, il tema dell’immigrazione e soprattutto dei rapporti con l’Islam “nazionale”, ma anche per esempio il nucleare. Su quest’ultimo punto il dibattito su un possibile, seppur difficile, ripensamento sembra essere partito, anche se l’asse culturale di comprensione del problema dei francesi è diverso dal nostro (hanno anche la bomba atomica). E poi gli interventi degli intellettuali, sempre molto seguiti.
Ma soprattutto questa campagna dovrà rilanciare in qualche modo i cosiddetti “valori repubblicani” (l’aggettivo “repubblicano” è probabilmente il più presente in ogni discorso politico da sempre), proprio quelli di libertà e uguaglianza ai quali tutti dicono di richiamarsi e che rappresentano gli elementi retorici importanti di un patto sociale e nazionale. Anche se qualcuno, come il noto cantante Philippe Katerine del video di seguito (quasi 300mila visite su youtube), comincia a dubitarne.

Le parole ci dividono

Mi sono concesso a New York qualche visita casuale a librerie (come anche a Chicago, che ha librerie molto belle), anche un po' per fiutare l'aria intellettuale che tira da quelle parti.  Nella libreria del Warner Trade Center, con vista Central Park e uno stile che evoca davvero una New York d'altri tempi, ho dato un'occhiata prima al reparto "attualità e politica", molto ricco e interessante, poi "storia", con gusti molto simili ai nostri, e infine "filosofia", che ho trovato davvero scarno in tutte le librerie che ho visto. Girando per gli altri reparti mi sono imbattuto, molto lontano da filosofia, negli scaffali "Metaphisical studies". Vedendo da lontano il reparto mi sono sorpreso che una tale specifica branca della filosofia fosse tematizzata a sè. Soprattutto perchè la cultura filosofica americana è storicamente lontana dagli interessi metafisici, più incardinata sul pragmatismo e sulla filosofia dell'educazione (un tempo), e ora attenta più che altro agli studi etici e analitici. Beh, arrivato al reparto ho visto che il primo scaffale dei "metaphisical studies" era organizzato nei seguenti sottoreparti: "Paranormal", "Aliens and Ufos", "Magical Studies". Mi sono allora rivolto con lo sguardo a "General metaphysics" per vedere che testi ci fossero, Aristotele o Kant, o chi altro. Ho trovato tra gli altri: "Afterlives of the rich and famous people" (Vite dell'aldilà di gente ricca e famosa) e "Bear speaks. 7 sacred lessons learned from a montana grizzly" (L'orso parla. 7 lezioni sacre imparate da un grizzly del Montana). Poi ho pensato all'etimologia di metafisica (che in effetti indica cose "oltre la natura", anche se in un senso filosofico), ma insomma sì, direi che rispetto a noi "metafisica" negli USA evidentemente vuol dire tutta un'altra cosa.
