The end justifies the means in all situations, Nobles should be driven solely by self-interest, and Nobles should rule the states - were not stated by Castiglione in The Book of the Courtier
Explanation:
Baldassare Castiglione's Book of the Courtier is a prolonged intellectual discourse, on the subject of what makes an ideal negotiator or, in the final chapter, a female of the court who deserves to be associated and to counsel a prince or a political leader.
In the book of the courtier, Castiglione stated that “Noble should follow a standard of conduct”
This vision became the moral objective of the aristocracy in Castiglione's view. A noble person has been made, not produced. His character, grace, and talent must be his. The noble must be a warrior, but he must also be trained and skilled in the arts. Ultimately, a respectable citizen had to meet those behavioral standards.
What were these standards intended?
The object of the proper Courtier... is to gain the respect and the heart of the Prince whom it serves to tell him the truth of all that he must know... and to try to challenge the Prince's mind when he sees him inclining in the wrong way... so as to dissuade him from the evil intent and put him into the road of goodness.
