What is new, however, is always evil, being that which wants to conquer and overthrow the old boundary markers and the old pieties; and only what is old is good. The good men are in all ages those who dig the old thoughts, digging deep and getting them to bear fruit - the farmers of the spirit. But eventually all land is depleted, and the ploughshare of evil must come again and again.
