Concept:
In Book V of his *Politics*, Aristotle provides a comprehensive analysis of the causes of "stasis" (revolution/instability) and the methods to preserve various forms of government.
Step 1: Causes of Revolution.
Aristotle believed that the main cause of revolution is the feeling of inequality—when people feel they are equal but are treated unequally, or when they feel superior but are treated only as equals.
Step 2: The Rule of Law.
To prevent this, Aristotle emphasized the importance of the spirit of law-abidingness. He argued that even small illegalities can creep in and eventually destroy a constitution. Therefore, the most important preventive measure is to train citizens (and the ruler) to respect the laws and prevent the "spirit of lawlessness" from taking root.
Step 3: Specific Advice for Monarchs.
Aristotle advised monarchs to avoid acting like tyrants. By maintaining the spirit of obedience to law and ensuring that the administration is seen as fair and not for personal gain, the monarch can prevent the resentment that leads to revolution.
