Context: The disastrous feature of our civilization is that it is far more developed materially than spiritually. Its balance is disturbed … Now come the facts to summon us to reflect. They tell us in terribly harsh language that a civilization which develops only on its material side, and not in the sphere of the spirit … heads for disaster.

“The triumph of the industrial arts will advance the cause of civilization more rapidly than its warmest advocates could have hoped, and contribute to the permanent prosperity and strength of the country far more than the most splendid victories of successful war.”

“[on the possibility of contact with an alien civilization]: I think it would be a disaster. The extraterrestrials would probably be far in advance of us. The history of advanced races meeting more primitive people on this planet is not very happy, and they were the same species. I think we should keep our heads low.”

“We must admit the vanity of our false distinctions among men and learn to find our own advancement in the search for the advancement of others.”

Robert F. Kennedy (1925–1968) American politician and brother of John F. Kennedy

On the Mindless Menace of Violence (1968)
Context: Yet we know what we must do. It is to achieve true justice among our fellow citizens. The question is not what programs we should seek to enact. The question is whether we can find in our own midst and in our own hearts that leadership of humane purpose that will recognize the terrible truths of our existence. We must admit the vanity of our false distinctions among men and learn to find our own advancement in the search for the advancement of others. We must admit in ourselves that our own children's future cannot be built on the misfortunes of others. We must recognize that this short life can neither be ennobled or enriched by hatred or revenge.
