Above All Remember Your Humanity.

My Third Appeal Is To My Fellow Citizens In All Countries: Help Us To Establish Lasting Peace In The World.

The Most Terrifying Moment In My Life Was October 1962, During The Cuban Missile Crisis. I Did Not Know All The Facts - We Have Learned Only Recently How Close We Were To War - But I Knew Enough To Make Me Tremble.

When The Start 2 Treaty Has Been Implemented - And Remember It Has Not Yet Been Ratified - We Will Be Left With Some 15,000 Nuclear Warheads, Active And In Reserve. Fifteen Thousand Weapons With An Average Yield Of 20 Hiroshima Bombs.

At A Time When Science Plays Such A Powerful Role In The Life Of Society, When The Destiny Of The Whole Of Mankind May Hinge On The Results Of Scientific Research, It Is Incumbent On All Scientists To Be Fully Conscious Of That Role, And Conduct Themselves Accordingly.

I Appeal To My Fellow Scientists To Remember Their Responsibility To Humanity.
