Doings Quotes (page 555)
I will try not to overlook the cruelties that victims inflict on one another as they are jammed together in the boxcars of the system. I don’t want to romanticize them. But I do remember (in rough paraphrase) a statement I once read: “The cry of the poor is not always just, but if you don’t listen to it, you will never know what justice is.
Howard Zinn
One of the reasons for its success is that science has a built-in, error-correcting machinery at its very heart.

When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.
Carl Sagan
