In many ways, no doubt, our world grows more and more complex, sputniks cannot be simple; yet how many of our complexities remain futile, how many of our artificialities false.

Extremism in defense of liberty is no vice; moderation is the pursuit of justice is no virtue.
The Negro has a callus growing on his soul and it is getting harder and harder to hurt him here. That is a simple law of nature. Like a callus on the foot in a shoe that is too tight. The foot is nature’s and that shoe was put on by man. The tight shoe will pinch your foot and make you holler and scream. But sooner or later, if you do not take the shoe off, a callus will form on the foot and begin to wear out the shoe.
It is the same with the Negro in America. That shoe-the white man’s system—has pinched and rubbed and squeezed his soul until it has almost destroyed him. But it did not.
