The key to life is to develop an internal moral, emotional GPS that can tell you which way to go.

The moral sense perhaps affords the best and highest distinction between man and the lower animals.

There can be only one permanent revolution- a moral one: the regeneration of the inner man.

I oppose the war in Vietnam because I love America. I speak out against it not in anger but with anxiety and sorrow in my heart, and above all with a passionate desire to see our beloved country stand as a moral example of the world.

We shall overcome because the arc of the moral universe is long, but it bends toward justice.

I am not interested in power for power's sake, but I'm interested in power that is moral, that is right and that is good.
