"Just as Darwin discovered the law of evolution in organic nature, so Marx discovered the law of evolution in human history; he discovered the simple fact, hitherto concealed by an overgrowth of idealogy [sic], that mankind must first of all eat and drink, have shelter and clothing, before it can pursue politics, science, religion, art etc."

What children don't understand, and can't understand until they grow up some, is how much the whole fabric and process of human society depends on everybody agreeing to ignore, most of the time, the fact that all of us are, most of the time, inadequate, incompetent, pitiful, and, in fact, naked to our enemies. None of us really has very much in the way of spiritual, moral clothing. We dress ourselves in rags. And we agree to say nothing about it. To a very large extent, it is human charity that clothes us.
