He described an ideal form of government in his writing.
Explanation:
The Greek philosopher Aristotle was a pupil of Plato and like his teacher, he was also interested in observing and describing/ working on what constitutes an ideal government. This stemmed from the wrongful accusation and death of Socrates which led to Pluto and eventually Aristotle critiquing and even suspecting a democratic government.
He famously stated in his "Politics" that <em>"man is by nature a political animal"</em>. Like his teacher Plato, he also developed his own ideas about what constitutes an ideal government and analyzed all forms of government.
