We are still waging Peloponnesian wars. Our control of the material world and our positive science have grown fantastically. But our very achievements turn against us, making politics more random and wars more bestial.
For some reason people who spend 40 years learning everything they can about, say, the Peloponnesian War – and indeed, advancing the body of human knowledge – get all pissy when their contributions are edited away by Randy in Boise who heard somewhere that sword-wielding skeletons were involved. And they get downright irate when asked politely to engage in discourse with Randy until the sword-skeleton theory can be incorporated into the article without passing judgment.
