"There is in them a natural madness, a rabid concupiscence, a wanton fancy, as is seen from their spiritual sins of pride, envy, and wrath.
For this reason they are the enemies of the human race: rational in mind, but reasoning without words; subtle in wickedness, eager to do hurt; ever fertile in fresh deceptions,
they change the perceptions and befoul the emotions of men,
they confound the watchful, and in dreams disturb the sleeping;
they bring diseases, stir up tempests, disguise themselves as angels of light,
bear Hell always about them..." - From 'The Malleus Maleficarum of
Heinrich Kramer and James Sprenger.'
