As for geoengineering, there have been serious general critiques that I think cannot be ignored, like Clive Hamilton's, along with many positive assessments. It is not a matter for subjective judgment based on guesswork and intuition. Rather, these are matters that have to be considered seriously, relying on the best scientific understanding available, without abandoning sensible precautionary principles.

If you are giving a graduate course you don't try to impress the students with oratory, you try to challenge them, get them to question you.

Take a look at the Supreme Court decision that just authorized an effort by U.S. claimants against Iran for terrorist acts. What are the terrorist acts? The terrorist acts are bombings of U.S. military installations in Lebanon and Saudi Arabia, which Iran is claimed to have something to do with. Well suppose they did. That's not terrorism. I mean if we have a military base in Lebanon that while we're shelling Lebanese naval ships, the Navy is shelling Lebanese installations and somebody attacks [that's not terrorism].

On the other hand, you have to balance that against expanding our nuclear forces, add to our so-called depleted military, which is already more powerful than the rest of the world combined; attack in Syria, send forces to Syria, start bombing. Who knows what could be next?

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.

There's kind of a hidden point which isn't being brought out, and that is that it is inconceivable that the U.S. would permit democracy in the Middle East, and for a very simple reason. Just take a look at polls of Arab public opinion. They exist. You can't find them in the press, but they exist from prestigious polling agencies. Released by major institutions. And what they show is that if there was democracy in the Middle East, the entire U.S. program for domination of the Middle East would be down the tube.

A basic principle of modern state capitalism is that costs and risks are socialized to the extent possible, while profit is privatized.
