know everything

Nor do I hold with those who regard it as a presumption if a man
of low and humble condition dare to discuss and settle the
concerns of princes; because, just as those who draw landscapes
place themselves below in the plain to contemplate the nature of
the mountains and of lofty places, and in order to contemplate the
plains place themselves upon high mountains, even so to understand
the nature of the people it needs to be a prince, and to
understand that of princes it needs to be of the people.
