Le grandi narrazioni implicite

Creare le strutture di partecipazione è una condizione necessaria ma non sufficiente per democratizzare effettivamente la conoscenza e l’expertise nei processi decisionali: aumentare il numero di voci può non portare di per sé a decisioni più sagge. In effetti, il rischio di estendere la partecipazione in sé è l’irrigidimento di alcune posizioni predefinite, oppure, all’estremo opposto, la decostruzione indefinitamente profonda del processo decisionale. È necessario, dunque, riflettere su come si canalizza l’immaginazione collettiva, come si stimolano la consapevolezza pubblica, il pensiero critico e creativo.

In un rapporto recente su scienza e governance per la Commissione Europea (Wynne B. et al. 2007) gli Autori riflettono sull’esistenza di narrazioni condivise che plasmano l’immaginazione collettiva e determinano un set di ‘dati di fatto’ sulla base dei quali si fonda il processo politico.

Nel mondo delle pratiche politiche, le narrazioni […] definiscono implicitamente gli orizzonti dell’azione possibile e accettabile, disegnano e impongono classificazioni, distinguono le questioni dalle non-questioni, gli attori dai non-attori. […] In molti aspetti chiave, le nostre istituzioni e le nostre modalità di scienza sono inquadrate da abitudini accumulate, immaginazioni e routines delineate da tali grandi narrazioni, le quali possono esser state valide in precedenza, ma con il cambiare dei tempi invitano nuove riflessioni e revisioni (European Commission 2007, p.73).

Una delle narrazioni più generali, o grande narrazione (master narrative), è quella del ‘mito del progresso’, in cui si associa il progresso sociale allo sviluppo tecnologico. Un’altra grande narrazione, molto influente e connessa al mito del progresso, è quella che individua nella moderna razionalità scientifica un tipo privilegiato di conoscenza, intrinsecamente più valido ed efficace di qualunque altra pratica culturale nell’interagire con la natura (Leach e Fairhead 2003). Il potere normativo di tali narrazioni si fonda sul meccanismo del selezionare ciò che conta come ‘prova’ e considerare ciò che non si vede come non necessario.

That's not surprising, since they backed a similar deal on Tuesday too. In the House, though, the deal went through 285 to 144. It had the support of 87 Republicans, but most opposed it.

    Prepare yourselves for a shocker: “The energy of photons really does just seep away as the universe expands,” Dr Andrew Pontzen tells me. This goes against our Earthly experiences, where energy is conserved, but according to Pontzen this energy loss is expected from Einstein’s theory of general relativity. “Over normal timescales, the universe does not change very much from one moment to the next. In physics, we call this a symmetry – an experiment done now will have the same result as an identical experiment done in a few minutes’ time (or a few years, or millennia),” he explains. “In the case of time symmetry, the result is energy conservation.” But take a very long timescale and the symmetry breaks down. “The universe is expanding, so it isn’t the same now as it was a billion years ago,” Pontzen says. “Precisely because of that, the energy inside the universe has not been conserved. Not that this should unsettle us. In the immediate surroundings of the Earth, nothing is expanding; the expansion takes place between widely separated galaxies. That means energy does not seep away from the Earth, the solar system, or even the galaxy. It’s only in intergalactic space that it gets lost.”
