A babe in Toyland. J.J. is always interesting.
Very true and interesting. Although it has to be said that there is a far simpler and perhaps more basic reason for it. Which is that symbols are by their very nature retro, and have to trail behind the times, simply because it takes time for them to be adopted by culture and become conventions. Much as mainstream education always trails ten or twenty years or more behind the latest scientific, political and historic thinking, simply because a time lag is inevitable.
