We must forever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again, we must rise to the majestic heights of meeting physical force with soul force.

The marvelous new militancy which had engulfed the Negro community must not lead us to a distrust of all white people, for many of our with brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny. And they have come to realize that their freedom is inextricable bound to our freedom.

We cannot walk alone. And as we walk, we must make the pledge that we shall always march ahead. We cannot turn back.

There are those who are asking the devotees of civil rights, "When will you be satisfied?" We can never be satisfied as long as the Negro is the victim of the unspeakable horrors of police brutality. We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motel of the highways and hotels of the cities. We cannot be satisfied as long as the negro's basic mobility is from a small ghetto to the larger one. We cannot never be satisfied as long as our children are stripped of their self-hood and robbed of their dignity by signs stating: "For Whites Only."

We must forever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again, we must rise to the majestic heights of meeting physical force with soul force.
