“More and more of our imports come from overseas.”

The Unseen Assassins https://archive.org/details/in.ernet.dli.2015.216538/page/n49 (1932), p. 48; in later variants, "pity" was misquoted as "piety" in the Naval War College Review, Vol. 10 (1957), p. 27, and some internet citations have compressed "has become, for the European of our age" to read "has become for our age".

The trial of Charles B. Reynolds for blasphemy (1887)
Context: I want you to understand what has been done in the world to force men to think alike. It seems to me that if there is some infinite being who wants us to think alike he would have made us alike. Why did he not do so? Why did he make your brain so that you could not by any possibility be a Methodist? Why did he make yours so that you could not be a Catholic? And why did he make the brain of another so that he is an unbeliever — why the brain of another so that he became a Mohammedan — if he wanted us all to believe alike?
After all, maybe Nature is good enough and grand enough and broad enough to give us the diversity born of liberty. Maybe, after all, it would not be best for us all to be just the same. What a stupid world, if everybody said yes to everything that everybody else might say.
The most important thing in this world is liberty. More important than food or clothes — more important than gold or houses or lands — more important than art or science — more important than all religions, is the liberty of man.

1963, Speech at Amherst College
Context: The artist, however faithful to his personal vision of reality, becomes the last champion of the individual mind and sensibility against an intrusive society and an officious state. The great artist is thus a solitary figure. He has, as Frost said, a lover's quarrel with the world. In pursuing his perceptions of reality, he must often sail against the currents of his time. This is not a popular role. If Robert Frost was much honored in his lifetime, it was because a good many preferred to ignore his darker truths. Yet in retrospect, we see how the artist's fidelity has strengthened the fibre of our national life. If sometimes our great artist have been the most critical of our society, it is because their sensitivity and their concern for justice, which must motivate any true artist, makes him aware that our Nation falls short of its highest potential. I see little of more importance to the future of our country and our civilization than full recognition of the place of the artist.
