1940s, Address accepting the Presidency of the CIO (1952)
I've often thought: Why is it that you can get a great nation like America marching, fighting, sacrificing, and dying in the struggle to destroy the master race theory in Berlin, and people haven't got an ounce of courage to fight against the master race theory in America? We need the same sense of dedication, the same courage, and the same determination to fight the immorality of segregation and racial bigotry in America as we did in the battlefields against Hitlersim.

Anarchism: Its Philosophy and Ideal (1896)
Context: These societies already begin to encroach everywhere on the functions of the State, and strive to substitute free action of volunteers for that of a centralized State. In England we see arise insurance companies against theft; societies for coast defense, volunteer societies for land defense, which the State endeavors to get under its thumb, thereby making them instruments of domination, although their original aim was to do without the State. Were it not for Church and State, free societies would have already conquered the whole of the immense domain of education. And, in spite of all difficulties, they begin to invade this domain as well, and make their influence already felt.
And when we mark the progress already accomplished in that direction, in spite of and against the State, which tries by all means to maintain its supremacy of recent origin; when we see how voluntary societies invade everything and are only impeded in their development by the State, we are forced to recognize a powerful tendency, a latent force in modern society.

Context: I like nature but not its substitutes. Naturalist art, illusionism, is a substitute for nature. I remember that in arguing with Piet Mondrian [in Paris, 1920's], he opposed art to nature saying that art is artificial and nature is natural. I do not share this opinion. I do not think that nature is in natural opposition to art. Art's origins are natural.

Variant: In war there is no substitute for victory.
Context: It seems strangely difficult for some to realize that here in Asia is where the Communist conspirators have elected to make their play for global conquest, and that we have joined the issue thus raised on the battlefield; that here we fight Europe’s war with arms while the diplomats there still fight it with words; that if we lose the war to communism in Asia the fall of Europe is inevitable, win it and Europe most probably would avoid war and yet preserve freedom. As you pointed out, we must win. There is no substitute for victory.
