Who Says Educational Standards Have Gone to Hell?

At Tufts, Dan Drezner is teaching Thucydides.  He has an interesting post, including a long quote from the historian, from which I'll excerpt two sentences:

"Reckless audacity came to be considered the courage of a loyal ally; prudent hesitation, specious cowardice; moderation was held to be a cloak for unmanliness; ability to see all sides of a question, inaptness to act on any."
