In my opinion, neither organisms nor organizations evolve slowly and surely into something better, but drift until some small change occurs which has immediate and overwhelming significance. The special role of the human being is not to wait for these favorable accidents but deliberately to introduce the small change that will have great significance.
To treat young men like men; to use modern recording techniques to capture the moment of exciting teaching; to gather ninety great men out of our one-hundred and seventy million — these, in retrospect, will seem like small changes indeed if they succeed in building a generation of greatness.
