In knowledge, causes become means and effects become consequences, and thereby things have meanings. The known object is an antecedent object as that is intentionally rearranged and redisposed, an eventual object whose value is tested by the reconstruction it effects. It emerges, as it were, from the fire of experimental thought as arefined metal issues from operations performed on crude material. It is the same object but the same object with adifference, as aman who has been through conditions which try the temper of his being comes out the same man and adifferent man.
