“The heritage we give our children, and the myths we leave to sustain them, must work with the tug and press of life, or they will fail. Adaptability has to be enshrined alongside stability, or the ghost of Darwin will surely come back to haunt us, whispering in our ears the penalty of conceit.
We wish our descendants happiness. But over time one criterion alone will judge our efforts.
Survival.”

1960s, Letter from a Birmingham Jail (1963)
Context: I have no fear about the outcome of our struggle in Birmingham, even if our motives are at present misunderstood. We will reach the goal of freedom in Birmingham and all over the nation, because the goal of America is freedom. Abused and scorned though we may be, our destiny is tied up with America's destiny. Before the pilgrims landed at Plymouth, we were here. Before the pen of Jefferson etched the majestic words of the Declaration of Independence across the pages of history, we were here. For more than two centuries our forebears labored in this country without wages; they made cotton king; they built the homes of their masters while suffering gross injustice and shameful humiliation -and yet out of a bottomless vitality they continued to thrive and develop. If the inexpressible cruelties of slavery could not stop us, the opposition we now face will surely fail. We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands.
