I saw science as being in harmony with humanity.
From my earliest days I had a passion for science.
The present basic philosophy is nuclear deterrence.
The Cold War is over but Cold War thinking survives.
But the nuclear powers still cling tenaciously to their weapons.
I appeal to my fellow scientists to remember their responsibility to humanity.
This means that the only function of nuclear weapons, while they exist, is to deter a nuclear attack.
My third appeal is to my fellow citizens in all countries: Help us to establish lasting peace in the world.
There is no direct evidence that nuclear weapons prevented a world war. Conversely, it is known that they nearly caused one.
The time has come to formulate guidelines for the ethical conduct of scientist, perhaps in the form of a voluntary Hippocratic Oath.
