We must abolish human poverty. We must eradicate killing and crippling disease and lengthen the span of life to 100 or 200 years. We must eliminate illiteracy among all of our people. We must end open bias and active bigotry and, above all else, we must help to bring about a day "when nation shall not lift up sword against nation, neither shall they learn war anymore."
