There's an all-enveloping destructiveness in Donald Trump's character and in his psychological tendencies. But I've focused on what professionally I call solipsistic reality. Solipsistic reality means that the only reality he's capable of embracing has to do with his own self and the perception by and protection of his own self. And for a president to be so bound in this isolated solipsistic reality could not be more dangerous for the country and for the world. He's not psychotic, but I think ultimately this solipsistic reality will be the source of his removal from the presidency.

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.

With the nuclear threat we know that if sufficient weapons are used, human civilization - all of humankind - could be extinguished literally by "nuclear winter." So we have to see ourselves as part of the ultimate human group, just as we have to do with global warming.

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.

As a kid I was fascinated with sports, and I loved sports more than anything else. The first books I read were about sports, like books about Baseball Joe, as one baseball hero was called.

There are people who believe that there should be a standard psychiatric examination for every presidential candidate and for every president. But these are difficult issues because they can't ever be entirely psychiatric. They're inevitably political as well. I personally believe that ultimately ridding the country of a dangerous president or one who's unfit is ultimately a political matter, but that psychological professionals can contribute in valuable ways to that decision.

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.
