“But no wall can be erected against Fortune which she cannot take by storm; let us strengthen our inner defences. If the inner part be safe, man can be attacked, but never captured.”

Speech to the American Legion convention, New York City (27 August 1952); as quoted in "Democratic Candidate Adlai Stevenson Defines the Nature of Patriotism" in Lend Me Your Ears : Great Speeches In History (2004) by William Safire, p. 81 - 82
Context: It was always accounted a virtue in a man to love his country. With us it is now something more than a virtue. It is a necessity. When an American says that he loves his country, he means not only that he loves the New England hills, the prairies glistening in the sun, the wide and rising plains, the great mountains, and the sea. He means that he loves an inner air, an inner light in which freedom lives and in which a man can draw the breath of self-respect.
Men who have offered their lives for their country know that patriotism is not the fear of something; it is the love of something.

“No use going out or staying at home. No use erecting walls against the impalpable.”
The Clerk's Vision (1949)
Context: No use going out or staying at home. No use erecting walls against the impalpable. A mouth will extinguish all the fires, a doubt will root up all the decisions. It will be everywhere without being anywhere. It will blur all the. mirrors. Penetrating walls and convictions, vestments and well-tempered souls, it will install itself in the marrow of everyone. Whistling between body and body, crouching between soul and soul. And all the wounds will open because, with expert and delicate, although somewhat cold, hands, it will irritate sores and pimples, will burst pustules and swellings and dig into the old, badly healed wounds. Oh fountain of blood, forever inexhaustible! Life will be a knife, a gray and agile and cutting and exact and arbitrary blade that falls and slashes and divides. To crack, to claw, to quarter, the verbs that move with giant steps against us!
It is not the sword that shines in the confusion of what will be. It is not the saber, but fear and the whip. I speak of what is already among us. Everywhere there are trembling and whispers, insinuations and murmurs. Everywhere the light wind blows, the breeze that provokes the immense Whiplash each time it unwinds in the air. Already many carry the purple insignia in their flesh. The light wind rises from the meadows of the past, and hurries closer to our time.
