Final answer:
Plato preferred an aristocracy led by philosopher-kings as the ideal system of government.
Step-by-step explanation:
Plato's preferred system of government was an aristocracy led by philosopher-kings. He believed that those who possessed wisdom and virtue should be in charge of ruling. Plato was critical of democracy and argued that it could lead to rule by the average and neglect the good of society as a whole. He proposed an organic society where each part contributes to the functioning of the whole. Plato's ideas on government, particularly the concept of philosopher-kings, have had significant influence on subsequent rulers and leaders.
