To Teresa

Miserabile. Aveva sopra il capo l’unico luogo stabile del
cosmo, l’unico riscatto alla dannazione del panta rei, e
pensava che fossero afiari Suoi, e non suoi. E infatti subito
dopo la coppia si allontan(cid:181)o|lui educato su qualche manuale
che gli aveva ottenebrato la possibilit(cid:181)a di meraviglia, lei
inerte, inaccessibile al brivido dell’inflnito, entrambi senza
aver registrato nella propria memoria l’esperienza terriflcante
di quel loro incontro|primo e ultimo|con l’Uno, l’En{sof,
l’Indicibile. Come non cadere in ginocchio davanti all’altare
della certezza?
(Umberto Eco, Il pendolo di Foucault, 1988)
