"There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless."
Niccolo Machiavelli was an Italian political philosopher, diplomat, and writer of the Renaissance. He is best known for The Prince and the Discourses on Livy. His work shaped later political theory and statecraft debates.
