The secret studies of an author are the sunken piers upon which is to rest the bridge of his fame, spanning the dark waters of oblivion. They are out of sight, but without them no superstructure can stand secure.
Henry Wadsworth LongfellowThe natural alone is permanent. Fantastic idols may be worshipped for a while; but at length they are overturned by the continual and silent progress of Truth, as the grim statues of Copan have been pushed from their pedestals by the growth of forest-trees, whose seeds were sown by the wind in the ruined walls.
Henry Wadsworth Longfellow
