Albert Einstein

“The pioneers of a warless world are the young men and women who refuse military service.”

“I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.”

“We must be prepared to make heroic sacrifices for the cause of peace that we make ungrudgingly for the cause of war. There is no task that is more important or closer to my heart.”

"Nothing that I can do will change the structure of the universe. But maybe, by raising my voice I can help the greatest of all causes - goodwill among men and peace on earth."
