Is Not This Unnatural?

     "Nature has established all things under the sun a certain term and pitch, when they shall make stay of increase and when they shall be multiplying; the land, if it lacks a jubilee, will in time grow heartless; houses if not repaired will decay; trees will stop bearing and cattle breeding when they grow old.  Men's labor and skill will fail with the passing of years.  Only the usurer's money doth multiply infinitely.  And this is not unnatural?"
