I try to encourage people to think for themselves, to question standard assumptions... Don't take assumptions for granted. Begin by taking a skeptical attitude toward anything that is conventional wisdom. Make it justify itself. It usually can't. Be willing to ask questions about what is taken for granted. Try to think things through for yourself.

As far as DSA is concerned, I'm perfectly happy to be associated with it while disagreeing with a large part of the leadership.

Sea level rise and destruction of water resources as glaciers melt alone may have horrendous human consequences.

My suspicion is that those who seem oblivious to suffering, whether it is nearby or in remote corners, are for the most part unaware, perhaps blinded by doctrine and ideology. For them, the answer is to develop a critical attitude toward articles of faith, secular or religious; to encourage their capacity to question, to explore, to view the world from the standpoint of others. And direct exposure is never very far away, wherever we live - perhaps the homeless person huddling in the cold or asking for a few pennies for food, or all too many more.

I was in Mexico City. It's a very pleasant city in many ways. It's vibrant, lively, pretty exciting society, but also depressing in other ways, and sometimes almost hopeless, you know. So it's a combination of vibrancy and, I wouldn't say despair, but hopelessness, you know. Doesn't have to be, but it is. I mean, there is almost no economy.

As far as Marx's analysis of capitalism, there's a lot of very useful ideas in it, but he's developing an abstract model of 19th century capitalism. It's abstract and it's changed.

The Russians were doing a lot of rotten things, you can point to them. But the idea that if you consider what Hans Morgenthau called "I called abuse of reality," the picture of the world was almost the opposite of what they presented. But somehow this sells and is continually repeated, at least in this kind of situation.
