" But I had learned to see another type of wildness, to which I had once been blind: the wildness of natural life, the sheer force of ongoing organic existence, vigorous and chaotic. This wildness was not about asperity, but about luxuriance, vitality, fun. The weed thrusting through a crack in a pavement, the tree root impudently cracking a carapace of tarmac: these were wild signs, as much as the storm wave and the snowflake. "
