Posseggono un intelletto in grado di sfiorar stelle e galassie, ma hanno anche uno stomaco dall'indole selvaggia e primordiale, un fuoco che sa di vita libera e pulsante. Guai però a quegli umani che si credano Dei oppure animali: il loro comportamento sarà per essi (e chi gli è appresso) il peggiore degli inferni. Peggio ancora per quegli sciocchi che credono d'esser immortali e potenti come Dei e feroci ed inconsapevoli come belve. A questi sciocchi spetterà il peggio in assoluto: il consumismo prima e l’estinzione poi, ossia la disperazione camuffata da gioia ed incalzata da una precoce morte. Sia chiaro, l’Universo e gli Dei non odiano la stupidità, ma, nel lungo periodo, non la tollerano. Semplicemente la stupidità non è né una virtù, né una dote che possa aumentare le probabilità di sopravvivenza. Pensare che l’Universo o gli Dei possano far un’eccezione per noi soltanto è da stupidi, o, se preferite, da consumisti in procinto d’estinguersi. La resilienza può sembrare la più materiale delle doti, ma include in sé spiritualità, intelligenza, bellezza, moderazione e rispetto.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1053025539775412746.post-56535631177407642482013-01-25T12:48:08.572+01:002013-01-25T12:48:08.572+01:00Se il giunco si piega l'onda passa.
