Eccentric endangerment

Rose (whose blog I unfortunately discovered too late because she's not blogging as much anymore) had a post with a quote from John Stuart Mill:

Eccentricity has always abounded when and where strength of character has abounded; and the amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigor, and moral courage which it contained. That so few now dare to be eccentric, marks the chief danger of the time.

Well, I don't think a lack of eccentricity is a "chief danger," but then again, he wrote that before a lot of horrible stuff happened even as societies became more "civilized" and industrialized and modern. But I do see how a lack of individuality creates group think and apathy.
