“In the vastness of the Cosmos there must be other civilizations far older and more advanced than ours.”

Kulturphilosophie (1923), Vol. 2 : Civilization and Ethics
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.

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.
