You bet he did, and we better know it by heart as well. The methods of ruling detailed by Machiavelli work. They worked in 15th century Italy and they work today.
Machiavelli was the father of modern political science. He has been and continues to be vilified by ignorant people who have never read his discourses or the prince. Reading him in Italian is even more inspiring as his prose, though not as good as Dante’s is clear and concise and compact and to the point. You need only to read those two works and you will understand human nature. Machiavelli viewed our fellow human beings with a characteristic detachment of an inanimate rock. He wasn’t interested in making value judgments or instilling upon his fellow man idealistic qualities that were not true to their nature. He wasn’t interested in social engineering, he knew human nature cannot be changed or molded. The founders of our republic were quite versed in Machiavelli and understood him best. They also were keen observers of human nature. Thus they designed a constitution to moderate the passions and the ;likely bad judgment we have as human beings. Machiavelli would have thus admired Adams, Jefferson, Hamilton, Franklin et al.
