“Let us close the springs of racial poison. Let us pray for wise and understanding hearts. Let us lay aside irrelevant differences and make our Nation whole.”

The Saviors of God (1923)
Context: I strive to discover how to signal my companions before I die, how to give them a hand, how to spell out for them in time one complete word at least, to tell them what I think this procession is, and toward what we go. And how necessary it is for all of us together to put our steps and hearts in harmony.
To say in time a simple word to my companions, a password, like conspirators.
Yes, the purpose of Earth is not life, it is not man. Earth has existed without these, and it will live on without them. They are but the ephemeral sparks of its violent whirling.
Let us unite, let us hold each other tightly, let us merge our hearts, let us create — so long as the warmth of this earth endures, so long as no earthquakes, cataclysms, icebergs or comets come to destroy us — let us create for Earth a brain and a heart, let us give a human meaning to the superhuman struggle.
This anguish is our second duty.

"Teacher"
The Children's Story (1982)
Context: Maybe we didn't pray hard enough. Perhaps we should kneel down like is done in church. Perhaps were using the wrong name. Instead of God, let's say "Our Leader." Let's pray to our leader for candy! Let's pray extra specially hard, and don't open your eyes until I say.

1860s, Cooper Union speech (1860)
Context: Neither let us be slandered from our duty by false accusations against us, nor frightened from it by menaces of destruction to the Government nor of dungeons to ourselves. Let us have faith that right makes might, and in that faith, let us, to the end, dare to do our duty as we understand it.

Address to joint session of Congress (10 April 1975)
1970s
Context: Let us put an end to self-inflicted wounds. Let us remember that our national unity is a most priceless asset. Let us deny our adversaries the satisfaction of using Vietnam to pit Americans against Americans.

Woman in the Nineteenth Century (1845)
Context: What I mean by the Muse is that unimpeded clearness of the intuitive powers, which a perfectly truthful adherence to every admonition of the higher instincts would bring to a finely organized human being. It may appear as prophecy or as poesy. … and should these faculties have free play, I believe they will open new, deeper and purer sources of joyous inspiration than have as yet refreshed the earth.
Let us be wise, and not impede the soul. Let her work as she will. Let us have one creative energy, one incessant revelation. Let it take what form it will, and let us not bind it by the past to man or woman, black or white.
