“Culture is the widening of the mind and of the spirit. It is never a narrowing of the mind or a restriction of the human spirit or the country's spirit.”

“The Spirit of Liberty” - speech at “I Am an American Day” ceremony, Central Park, New York City (21 May 1944).

Context: What do we mean when we say that first of all we seek liberty? I often wonder whether we do not rest our hopes too much upon constitutions, upon laws and upon courts. These are false hopes; believe me, these are false hopes. Liberty lies in the hearts of men and women; when it dies there, no constitution, no law, no court can save it; no constitution, no law, no court can even do much to help it… What is this liberty that must lie in the hearts of men and women? It is not the ruthless, the unbridled will; it is not the freedom to do as one likes. That is the denial of liberty and leads straight to its overthrow. A society in which men recognize no check on their freedom soon becomes a society where freedom is the possession of only a savage few — as we have learned to our sorrow.
What then is the spirit of liberty? I cannot define it; I can only tell you my own faith. The spirit of liberty is the spirit which is not too sure that it is right; the spirit of liberty is the spirit which seeks to understand the minds of other men and women; the spirit of liberty is the spirit which weighs their interests alongside its own without bias; the spirit of liberty remembers that not even a sparrow falls to earth unheeded; the spirit of liberty is the spirit of Him who, near two thousand years ago, taught mankind that lesson it has never learned, but has never quite forgotten; that there may be a kingdom where the least shall be heard and considered side by side with the greatest.

Context: We are all sons and daughters of the Most High, but the Anointed One was His first-born, who dwelt in the body of Jesus of Nazareth, and He walked among us and we beheld Him.
All this I say that you may understand not only in the mind but rather in the spirit. The mind weighs and measures but it is the spirit that reaches the heart of life and embraces the secret; and the seed of the spirit is deathless.
The wind may blow and then cease, and the sea shall swell and then weary, but the heart of life is a sphere quiet and serene, and the star that shines therein is fixed for evermore.
