Full quote: "For millions of years mankind lived just like the animals. Then, something happened which unleashed the power of our imaginations. We learned to talk and we learned to listen. Speech has allowed communication of ideas, enabling human beings to work together to build the impossible. Mankind's greatest achievements have come about by talking, and its greatest failures by not talking. It doesn't have to be like this. Our greatest hopes could become reality in the future.(Out of room)
