Smallpox was the worst disease in history. It killed more people than all the wars in history.

Google's a strange place. When I met Eric Schmidt, he said, "If you are kind to everybody, then you will make good decisions because people will give you good information, and if you are truthful to everybody, they will be truthful to you." That's what's different about Google. They screw up and make mistakes, but they genuinely mean the good stuff about "don't be evil."

In 1980 we declared the globe free of smallpox. It was the largest campaign in United Nations history until the Iraq war. A hundred and fifty thousand people from all over the world, doctors of every race, religion, culture and nation, who fought side by side, brothers and sisters, with each other, not against each other, in a common cause to make the world better.

If you are constantly making judgments based on superficial affiliations, your world gets to be pretty small.

Life didn't just happen to them. They experienced life at a deeper level than I had ever experienced it. I had been a radical, a left-wing politico, and meeting the Indian people made me realize that the politics of the left and the right were so much less important than the politics of the heart and the spirit.

Smallpox was the worst disease in history. It killed more people than all the wars in history.

I make a hundred mistakes a day. I am, and have been, and will continue to be, wrong about almost everything.
