The scientists who made the atomic bomb are, in my sense, people with a tragic destiny. You know, there was the US race with Nazi Germany and good evidence that the Germans were more advanced in nuclear physics, and we had to get the bomb first. But then there was the use of that dreadful weapon, or instrument of genocide, and many of the more sensitive scientists turned quickly into anti - nuclear people - and very effective ones.

There's more and more recognition that a carbon economy is dangerous to us economically. And there is increasing recognition that renewable fuels have economic value as well as obvious value for our health and our well-being and our survival. In fact, as you know, the economic revolution in renewable fuels has been impressive. It really had not been anticipated.

Every adult in the world has some sense that he or she might be obliterated at any time by these weapons that we have created.

In early psychoanalytic thought, narcissism was - and still, of course, is - self-love. The early psychoanalysts used to talk of libido directed at the self. That now feels a little quaint, that kind of language. But it does include the most fierce and self-displaying form of one's individual self. And in this way, it can be dangerous. When you look at Donald Trump, you can really see someone who's destructive to any form of life enhancement in virtually every area. And if that's what Fromm means by malignant narcissism, then it definitely applies.

The American president has particular power. This makes Trump the most dangerous man in the world. He's equally dangerous because of his finger on the nuclear trigger and because of his mind ensconced in solipsistic reality. The two are a dreadful combination.

It may sound terrible, but I often say that the military saved me from a conventional life in the United States and I've never really thanked them for it, because I haven't exactly been pro-military in my work.

While Donald Trump doesn't have any systematic ideology, he does have a narrative, and in that narrative, America was once a great country, it's been weakened by poor leadership, and only he can make it great again by taking over. And that's an image of himself as a strongman, a dictator. It isn't the clear ideology of being a fascist or some other clear-cut ideological figure. Rather, it's a narrative of himself as being unique and all-powerful. He believes it, though I'm sure he's got doubts about it.
