Introductory:
a "The Lord stood upon a wall made by a plumbline, with a plumbline in his hand.
And the Lord said unto me, Amos, what seest thou? And I said, A plumb-line. Then said the Lord, Behold, I will set a plumbline in the midst of my people, Israel: I will not again pass them by any more." (Amos VII, vv. 7, 8)
b "To study something of great age until one grows familiar with it and
almost to live in its time, is not merely to satisfy a curiosity or to establish aimless truths; it is rather to fulfil a function whose appetite has always rendered History a necessity.
By the recovery of the Past, stuff and being are added to us; our lives, which, lived in the present only, are only a film or surface, take on body-are lifted into one dimension more."
-Hilaire Belloc, "The Old Road."
