It is true that classical libertarian thought is opposed to state intervention in social life, as a consequence of deeper assumptions about the human need for liberty, diversity, and free association.

The beam in our own eye is harder to detect, although - or more accurately because - to detect it, and remove it, is vastly more important on elementary moral grounds, and commonly more important in terms of direct human consequences as well. Intellectuals have historically played a critical function in performing these tasks, and [Ivan] Illich is right to observe that claims to scientific expertise and special knowledge are often used as a device.

As for climate change, it's by now widely accepted by the scientific community that we have entered a new geological era, the Anthropocene, in which the Earth's climate is being radically modified by human action, creating a very different planet, one that may not be able to sustain organized human life in anything like a form we would want to tolerate.

The people of the Third World need our sympathetic understanding and, much more than that, they need our help. We can provide them with a margin of survival by internal disruption in the United States. Whether they can succeed against the kind of brutality we impose on them depends in large part on what happens here.

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.

United States has comparative advantage in military force. It tends to react to anything at first with military force, that's what it's good at. And I think they overdid it. There was more military force than was necessary.

As for the various religions, there's no doubt that they are very meaningful to adherents, and allow them to delude themselves into thinking there is some meaning to their lives beyond what we agree is the case. I'd never try to talk them out of the delusions, which are necessary for them to live a life that makes some sense to them. These beliefs can provide a framework for deeds that are noble or savage, and anywhere in between, and there's every reason to focus attention on the deeds and the background for them, to the extent that we can grasp it.
