Aristotle
via wikipedia:
"Aristotle is often portrayed as disagreeing with his teacher Plato (e.g., in Raphael's School of Athens). He criticizes the regimes described in Plato's Republic and Laws,[61] and refers to the theory of forms as "empty words and poetic metaphors."[62] He is generally presented as giving greater weight to empirical observation and practical concerns."

"Aristotle, in his Politics, criticises many aspects of Plato's political theory, and sets out his own ideas about how a perfect city should be governed. Rather than proposing, as Plato does, the establishment of a ruling class, Aristotle argues that all citizens should take an equal share in the administration of the city. However, in one passage (book 3, ch. 13), Aristotle does write that if one or more people happened to be found who far excelled their fellow citizens in virtue, it would be against the natural order for such people to be subject to the rule of their inferiors, and they should therefore be made "kings in their state for life". While Aristotle here comes close to endorsing the philosopher-king ideal, he does not expressly state that this virtuous leader should be skilled in philosophy, and his writings more usually draw a sharp distinction between the theoretical wisdom of a philosopher and the political wisdom of a ruler.[10]"
