“Uniformity is death. Diversity is life”

Mikhaïl Bakounine

"Perfection isn't when there is nothing left to add, but when there is nothing left to take away."

Antoine de Saint-Exupery

There's a nice quote from George Bernard Shaw on the same subject: "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."

It's more demonstrative imho ^^
