My cool judgement is, that if all the other doctrines of devils which have been committed to writing since letters were in the world were collected together in one volume, it would fall short of this; and that, should a Prince form himself by this book, so calmly recommending hypocrisy, treachery, lying, robbery, oppression, adultery, whoredom, and murder of all kinds, Domitian or Nero would be an angel of light compared to that man.

Summary

This quote expresses a strong disapproval of a book that supposedly promotes immoral and evil behaviors. The speaker suggests that the doctrines contained within this book exceed in wickedness all other writings in the world. They go on to claim that if a leader were to adopt the principles of this book, promoting hypocrisy, treachery, deception, injustice, promiscuity, and various forms of murder, even ruthless historical figures like Domitian or Nero would pale in comparison to the darkness this individual would embody.
