"There is such a thing as fighting the battle of democracy in the front rank too long. It is ever the Aristides experience over again. Everybody remembers Aristides— the sturdy citizen of the Athenian democracy, who was one of the generals at Marathon, one of the victorious captains at Salamis, the conqueror at Plataea, who put through with a punch a very much needed programme of civic reform in Athens, and helped organize the Delian League with the purpose of making Greece a real nation at the time when she was able to be one. He pushed the Athenian democracy to the point of diminishing returns; the people had an attack of fatigue, escorted Aristides to the city gate, and bowed him into the ostracism of silence. That has been the way with democracies. They get over their blue funk after a while. Everbody in Greece is for Aristides now. But he is dead. And it is too late. It is yet a question whether the American democracy has learned its lesson from history so that it knows how to value its Aristides citizens, little and big."
