The Prince: Novel Summary: Chapters 21-22
Chapter 21: Next, Machiavelli admires King Ferdinand of Spain for his successes, both military and political. He especially admires Ferdinand for using Christianity as an excuse to drive out the Moors from southern Spain.
Lastly, Machiavelli asserts that for the purposes of war, a wise prince should never make friends with someone more powerful than he is, because if this powerful "friend" is successful, the prince will be indebted to his ally, which will lead to troublesome situations. Most of all, the prince should always appear majestic, someone above the quarrels of others.
Chapter 22: Here, Machiavelli considers the servants, or secretaries of the prince. These men are of the utmost importance, because without them, the prince will not be able to administer his government. To find good servants, the prince must make sure that the men he employs look out for his interests before theirs. Most importantly, the prince and the servant must have a mutual respect and trust for one another.
