I am reading the Wikipedia entry for Clown, as for some reason I thought they would be close to Religion historically, and found this sentence
"It seems plausible that folly and fools, like religion and magic, meet some deeply rooted needs in human society."
Source https://en.wikipedia.org/wiki/Clown history section
What does "folly and fools" mean in this sentence, as I can not see how the standard meaning would fit in. It seems to me that it may mean Clown to some extent but cant be sure.
