Now there is a foolish argument advanced by those who want to reassure the citizens. Philip, they say, after all is not yet what the Lacedaemonians were; they were masters of every sea and land; they enjoyed the alliance of the king of Persia; nothing could stand against them: and yet our city defended itself even against them and was not overwhelmed. But for my own part, while practically all the arts have made a great advance and we are living today in a very different world from the old one, I consider that nothing has been more revolutionized and improved than the art of war.
