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.
Noam ChomskyThe people we call the prophets I think are the earliest dissident intellectuals, and they're treated like most dissident intellectuals - very badly. They're imprisoned, driven into the desert. King Ahab, the epitome of evil in the Bible, condemned Elijah as a "hater of Israel." This is the first self-hating Jew, the origin of the term. It goes right up to the present. That's the history of intellectuals.
Noam ChomskyDemocracy, in the United States rhetoric refers to a system of governance in which elite elements based in the business community control the state by virtue of their dominance of the private society, while the population observes quietly. So understood, democracy is a system of elite decision and public ratification, as in the United States itself. Correspondingly, popular involvement in the formation of public policy is considered a serious threat. It is not a step towards democracy; rather it constitutes a 'crisis of democracy' that must be overcome.
