Hippodamus of Miletus

According to Aristotle's description in Politics, "Some people thought he carried things too far, indeed, with his long hair, expensive ornaments, and the same cheap warm clothing worn winter and summer.

"[5] In the treatise On Virtue, Theano (apparently the wife of Pythagoras) addressed a certain Hippodamus of Thurium (presumably this same man) that her work contains the doctrine of the golden mean.

[6] According to Aristotle (in Politics ii.8), Hippodamus was a pioneer of urban planning, and he devised an ideal city to be inhabited by 10,000 men[5] (free male citizens), while the overall population (including women, children, and slaves) would reach 50,000.

[7] Aristotle's own concept of polity included a large middle class in which each citizen fulfilled all three functions of self-legislation, arms bearing, and working.

He laid out the Piraeus (the port of Athens) for Pericles, with wide streets radiating from the central Agora, which was generally called the Hippodameia (Ἱπποδάμεια) in his honour,[8][9] and built the refounded city of Rhodes[10] in the form of a theater.

What is most impressive in his plan is a wide central area, which was kept unsettled according to his macro-scale urban prediction/estimation and in time evolved to the "Agora", the centre of both the city and the society.

Aristotle essentially foreshadowed the inherent tension between private rewards for social benefits - the potential diversion between individual and societal interests.
