For some reason, having a developed aesthetic sense isn't that common.
Why is most music on the radio so crappy? Because most people do not have the 'ear', they lack the aesthetic sense to know the difference, they even lack the ability to know when a song sounds like utter shit and depend on what others say about this song in order to evaluate it. I know tons of people who can't tell which note is sharper when they hear two close notes.
Many people wouldn't recognize the divine even if it slapped their faces.
