“But they will give straight judgements to strangers and to the men of the land, and go not aside from what is just, their city flourishes, and the people prosper in it.”

XVII. 485–487 (tr. G. H. Palmer).

Collected Poems (1992)
Context: The people going by would gaze at him,
and one would ask the other if he knew him,
if he was a Greek from Syria, or a stranger.
But some who looked more carefully
would understand and step aside;
and as he disappeared under the arcades,
among the shadows and the evening lights,
going toward the quarter that lives
only at night, with orgies and debauchery,
with every kind of intoxication and desire,
they would wonder which of Them it could be,
and for what suspicious pleasure
he had come down into the streets of Selefkia
from the August Celestial Mansions.

1960s, Remarks at the signing of the Immigration Bill (1965)
Context: This bill says simply that from this day forth those wishing to immigrate to America shall be admitted on the basis of their skills and their close relationship to those already here. This is a simple test, and it is a fair test. Those who can contribute most to this country; to its growth, to its strength, to its spirit; will be the first that are admitted to this land. The fairness of this standard is so self-evident that we may well wonder that it has not always been applied. Yet the fact is that for over four decades the immigration policy of the United States has been twisted and has been distorted by the harsh injustice of the national origins quota system. Under that system the ability of new immigrants to come to America depended upon the country of their birth. Only 3 countries were allowed to supply 70 percent of all the immigrants. Families were kept apart because a husband or a wife or a child had been born in the wrong place. Men of needed skill and talent were denied entrance because they came from southern or eastern Europe or from one of the developing continents. This system violated the basic principle of American democracy; the principle that values and rewards each man on the basis of his merit as a man. It has been un-American in the highest sense, because it has been untrue to the faith that brought thousands to these shores even before we were a country. Today, with my signature, this system is abolished. We can now believe that it will never again shadow the gate to the American nation with the twin barriers of prejudice and privilege. Our beautiful America was built by a nation of strangers. From a hundred different places or more they have poured forth into an empty land, joining and blending in one mighty and irresistible tide. The land flourished because it was fed from so many sources; because it was nourished by so many cultures and traditions and peoples. And from this experience, almost unique in the history of nations, has come America's attitude toward the rest of the world. We, because of what we are, feel safer and stronger in a world as varied as the people who make it up; a world where no country rules another and all countries can deal with the basic problems of human dignity and deal with those problems in their own way. Now, under the monument which has welcomed so many to our shores, the American nation returns to the finest of its traditions today. The days of unlimited immigration are past. But those who do come will come because of what they are, and not because of the land from which they sprung.

On the Irrepressible Conflict (1858)
Context: As a general truth, communities prosper and flourish, or droop and decline, in just the degree that they practise or neglect to practise the primary duties of justice and humanity. The free-labor system conforms to the divine law of equality, which is written in the hearts and consciences of man, and therefore is always and everywhere beneficent.
The slave system is one of constant danger, distrust, suspicion, and watchfulness. It debases those whose toil alone can produce wealth and resources for defence, to the lowest degree of which human nature is capable, to guard against mutiny and insurrection, and thus wastes energies which otherwise might be employed in national development and aggrandizement. The free-labor system educates all alike, and by opening all the fields of industrial employment and all the departments of authority, to the unchecked and equal rivalry of all classes of men, at once secures universal contentment, and brings into the highest possible activity all the physical, moral, and social energies of the whole state.
