What can realistically be done depends on the historical moment. The same is true with regard to the agents.

We can try to gain some of the sensibility of some of the indigenous populations of the world or our predecessors 800 years ago. We can laugh at them as being naive and unsophisticated, but unless we can gain that sensibility that there has to be rights of nature as Bolivians and others put it, then we're going to be destroyed.

So, at one extreme you have indigenous, tribal societies trying to stem the race to disaster. At the other extreme, the richest, most powerful societies in world history, like the United States and Canada, are racing full-speed ahead to destroy the environment as quickly as possible.

For those of us who got into good colleges or the professions, did we stand up to that high school history teacher who told us some ridiculous lie about American history and say, "That's a ridiculous lie. You're an idiot"? No. We said, "All right, I'll keep quiet, and I'll write it in the exam and I'll think, yes, he's an idiot." And it's easy to say and believe things that improve your self-image and your career and that are in other ways beneficial to yourselves.

Biblical archaeology was developed early in this century in an effort to substantiate the authenticity of the Biblical account. It's by now generally recognized in Biblical scholarship that it has done the opposite. The Bible is not a historical text, and has only vague resemblances to what took place, as far as can be reconstructed. For example, whether Israel ever existed is not clear; if so, it was probably a small kingdom somewhere in the hills, apparently virtually unknown to the Egyptians.

To use the terms that are reserved for official enemies, it is the commissars and apparatchiks, not the dissidents, who are respected and privileged within their own societies.

Those who wish to change the world should have the best possible understanding of the world, including what is revealed by the sciences, some of which they might be able to use for their purposes. That's why workers education, including science and mathematics, has commonly been a concern of left intellectuals.
