To see the human mind in one of the most enlightened nations of the
world, and after a lapse of some thousand years, debased by such a
fermentation of disgusting passions, of fear, cruelty, malice, revenge,
ambition, madness, and folly as would have disgraced the most savage
nation in the most           age must have been such a tremendous shock
to his ideas of the necessary and inevitable progress of the human mind
that nothing but the firmest conviction of the truth of his principles,
in spite of all appearances, could have withstood.
