Those who visit this blog on a regular basis know that I'm a fan of Solon and his reformations of the political landscape of Athens in the sixth century BC. Solon (Σόλων) was an Athenian statesman and lawmaker who lived from 638 BC to 558 BC. He spent most of his adult life trying to legislate against political, economic, and moral decline in archaic Athens. His ideologies are often credited with having laid the foundations for Athenian democracy. Solon's reforms created a system where the power was in the hands of the people instead of leaving justice to be administered by the aristocracy. With current affrairs being what they are, I'd like to quote Aeschines today, from "Against Timarchus"
“[Solon] believed that someone who managed their own personal affairs badly would manage matters of state similarly. It did not seem likely to the lawgiver that that the same person who was a scoundrel in private would be a useful citizen in public. He also did not think right that a person should come to speak in public before being prepared for it, not just for words but in life.

And he also thought that advice from a good and noble person, however poorly and simply it was framed, is beneficial to those who hear it, while the words of a person who has no shame, who has made a mockery of his own body and who has shamefully managed his inheritance—well, these words he believed would never help the people who heard them, not even if they were delivered well.

This is why he keeps these kinds of people from the platform, why he forbids them from addressing the public. If someone speaks, then, not merely against these precepts but also for the sack of bribery and criminality, and if the state can no longer endure such a person, he adds “Let any citizens who desires it, and who is able, sue him…”
