The entirety of Charlie Chaplin's speech from "The Great Dictator" but this paragraph in particular:
Greed has poisoned men's souls, has barricaded the world with hate, has goose-stepped us into misery and bloodshed. We have developed speed, but we have shut ourselves in.
Machinery that gives us abundance has left us in want.
Our knowledge has made us cynical.
Our cleverness, hard and unkind.
We think too much and feel too little.
More than machinery, we need humanity.
More than cleverness, we need kindness and gentleness.
Without these qualities, life will be violent, and all will be lost.
