Reason must be the universal rule and guide; all things must be done according to reason without allowing oneself to be swayed by emotion.

Nothing so upholds the laws as the punishment of persons whose rank is as great as their crime.

Harshness towards individuals who flout the laws and commands of the state is for the public good; no greater crime against the public interest is possible than to show leniency to those who violate it.

Nothing is as dangerous for the state as those who would govern kingdoms with maxims found in books.

Never write a letter and never destroy one.

Reason must be the universal rule and guide; all things must be done according to reason without allowing oneself to be swayed by emotion.

We may employ artifice to deceive a rival, anything against our enemies.
