While he has been mocked as St. Bono, he strives not to be too single-minded. He says 'Edge is always whispering in my ear: "You're an artist. That's how you're getting away with this. If you start to behave in a correct fashion and very serious and doing a serious job, it's awful." '
When a Roman general had won a great military victory he would celebrate with a triumph- kind of like a big tickertape parade. The army would march through the city displaying all the plunder and prisoners of war they had brought back while the people lined the streets to cheer them on. The general himself would ride along in a magnificent chariot pulled by white horses. Apparently the whole spectacle was so magnificent and so overwhelming that a slave would stand behind the general, on his chariot, and whisper into his ear to remind him that he was just a human, not a god.
Here's how Tertullian describes it:
Hominem se esse etiam triumphans in illo sublimissimo curru admonetur. suggeritur enim ei a tergo, 'Respice post te! Hominem te memento!' Et utique hoc magis gaudet tanta se gloria coruscare, ut illi admonitio condicionis suae sit necessaria.
Even as he celebrates his triumph in that most exalted chariot, he is warned that he is, after all, human. For from behind him a voice whispers, 'Look behind you! Remember you are human!' And he delights all the more in this fact, that he shines with such great glory, that he needs a warning in regards to his condition.
