Final answer:
The 'father of political philosophy' among the Greeks is Socrates, whose ideas were expanded by his student Plato. Plato envisioned a society led by philosopher-rulers, while Aristotle, Plato's student, emphasized the role of empirical observation and community in achieving a virtuous life.
Step-by-step explanation:
The "father of political philosophy" among the Greeks is considered to be Socrates. His student, Plato, further developed his ideas, and Plato's student, Aristotle, expanded upon these philosophies even further. Socrates's legacy is mostly preserved through the writings of Plato.
In the context of ancient Greek philosophy, Aristotle broke with Plato's theory of relying only on contemplation for political insight; instead, he advocated for the importance of empirical observations and the role of the community in developing virtue. Aristotle viewed humans as "political animals" and believed that living in a proper political society is a key component to living a good and virtuous life.
