“When we are all in a culture together, we share a secret with each other, and this is true of every civilization down through time. Not even their art, not even their laws, their artifacts, their literature, their philosophies, their wars, their stone bowls can ever reveal that civilization's secret. Even today, with all we've built that will outlast us, we will not leave behind the secret that binds us. In this way, we are like any family at the core of which there is a secret that, even if someone asked, one one in that family -not even the snitchy, untrustworthy types - could ever reveal. In this way, we are all like a family together in the present, and no future civilization will every know our secret - the secret of our existence together - just as we do not know the secrets that have lived and died with the past.”
