The world was warned of extremely severe dangers unless urgent steps are taken to deal with global warming.

Suppose that I see a hungry child in the street, and I am able to offer the child some food. Am I morally culpable if I refuse to do so? Am I morally culpable if I choose not to do what I easily can about the fact that 1000 children die every hour from easily preventable disease, according to UNICEF? Or the fact that the government of my own "free and open society" is engaged in monstrous crimes that can easily be mitigated or terminated? Is it even possible to debate these questions?

If you listen to the talk shows, which are rabid right-wing, and very interesting, an important fact about the United States, they reach a huge audience. And they're very uniform. So right wing, I don't think you can even find an analog in your, but they reach a mass audience, and their view is that the corporations are liberal.

The person who wins the Nobel Prize is not the person who read the most journal articles and took the most notes on them. It's the person who knew what to look for.

The basic principle, rarely violated, is that what conflicts with the requirements of power and privilege does not exist.
