A prince will never lack for legitimate excuses to explain away his breaches of faith. Modern history will furnish innumerable examples of this behavior, showing how the man succeeded best who knew best how to play the fox.

Men are so simple of mind, and so much dominated by their immediate needs, that a deceitful man will always find plenty who are ready to be deceived.
