Instinct creates the recurring and the beautiful, all the winding of the serpent; but reason, the most ugly man, as Blake called it, is a drawer of the straight line, the maker of the arbitrary and the impermanent, for no recurring spring will ever bring again yesterday’s clock. Sanctity has its straight line also, darting from the centre, and with these arrows the many-coloured serpent, theme of all our poetry, is maimed and hunted. He that finds the white arrow shall have wisdom older than the Serpent, but what of the black arrow. How much knowledge, how heavy a quiver of the crow-feathered ebony rods can the soul endure?
