Progress changes consciousness, and when people's consciousness changes, then their awareness of what is possible changes as well - a virtuous circle.
The greatest progress we have made, and the greatest progress we have yet to make, is in the human heart. In the end, all the world's wealth and a thousand armies are no match for the strength and decency of the human spirit.
Nothing in our lifetimes has been more heartening than when people of the former Soviet Union and Central Europe broke the grip of communism. We have aided their progress and I am proud of it.
