New Wine in Old Wineskins <- not always the best metaphor

"But the heart of Pacifica had always been and remained today the tropical islands of the ocean called Pacific in memory of the largest sea on Earth. The dwellers on these islands lived, not precisely in the old ways, but with the memory of the old ways still in the background of all sounds and at the edges of all sights. Here the sacred kava was still sipped in the ancient ceremonies. Here the memories of ancient heroes were kept alive. Here the gods still spoke into the ears of holy men and women. And if they went home to grass huts containing refrigerators and networked computers, what of that? The gods did not give unreceivable gifts. The trick of it was finding a way to let new things into one's life without killing that life to accommodate them." - Orson Scott Card in his book Children of the Mind
