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.

Personally, I am uneasy about the notion of "a politically engaged university," for reasons I wrote about over 30 years ago, at the height of protest and resistance (reprinted in For Reasons of State).

No liberal newspaper ever talked about the invasion of Vietnam; they talked about the defense of Vietnam. And then they were saying, "well, it's not going well." Ok, that make them liberal. It's like, it's if we were to say, that going back to, say, Nazi Germany, that Hitler's general staff was liberal after Stalingrad because they were criticizing his tactics: "It was a mistake to fight a two front war, we should've knocked off Englad first," or something.

If commissars in Soviet Russia agreed to subordinate themselves to state power, they could at least plead fear in extenuation. Their counterparts in more free and open societies can plead only cowardice.

I mean, what's the elections? You know, two guys, same background, wealth, political influence, went to the same elite university, joined the same secret society where you're trained to be a ruler - they both can run because they're financed by the same corporate institutions.

A corporation is a state created institution, state supported institution, its concentration of private power, there is no reason why it should have the rights of persons.

To construct a scientific theory from the data and to be able to recognize that it is a reasonable theory is possible only if there are some very sharp restrictive principles that lead you to go in one direction and not in another direction. Otherwise, you wouldn't have science at all, merely randomly chosen hypotheses.
