Nature teaches more than she preaches. There are no sermons in stones. It is easier to get a spark out of a stone than a moral.

Nature comes home to one most when one is at home. The stranger and traveler finds her a stranger and traveler also.

One can only learn his powers of action by action, and his powers of thought by thinking

Nature exists for man no more than she does for monkeys, and is as regardless of his life or pleasure or success as she is of the fleas. Her waves will drown him, her fire burn him, and her earth devour him, her storms and lightning smite him, as if he were only a dog.

The International Court of Justice (a.k.a. World Court) is the judicial branch of the United Nations and in the early 1990's a campaign started and it was supported by civil society non-governmental groups around the world.

The thing that I focus on because I don't think it gets enough attention is that among the world's major powers, there is still a nuclear balance of terror - I'm talking about between the United States and Russia, the United States and China.

There tends to be this comfortable assumption that nuclear weapons won't be used, but I don't think that's warranted, and I think we should seize the opportunity of this time of stability and cooperation and move towards global elimination of nuclear weapons as indeed people like Henry Kissinger, and William Perry, former Secretary of Defense under Clinton, and Sam Nunn, former Senator, and George Schultz, former Undersecretary of State for Ronald Reagan. All of them recently called for achievement of a nuclear weapon-free world.
