The "Father of Political Science" is widely regarded as Aristotle, a Greek philosopher who lived in the 4th century BCE. Aristotle's works, including "Politics" and "Nicomachean Ethics," provide foundational ideas and concepts in political theory and have influenced political thought for centuries. He believed in the importance of studying political systems and human behavior to understand the nature of society and government. Aristotle's work remains relevant to this day, and his ideas continue to shape political philosophy and the study of politics.
