Wallace Stegner said this quote
“ Civilizations grow by agreements and accomodations and accretions, not by repudiations. The rebels and the revolutionaries are only eddies, they keep the stream from getting stagnant but they get swept down and absorbed, they're a side issue. Quiet desperation is another name for the human condition. If revolutionaries would learn that they can't remodel society by day after tomorrow -- haven't the wisdom to and shouldn't be permitted to -- I'd have more respect for them ... Civilizations grow and change and decline -- they aren't remade. ”
