Trump has a mind that in many ways is always under duress, because he's always seeking to be accepted, loved. He sees himself as constantly victimized by others and by the society, from which he sees himself as fighting back. So there's always an intensity to his destructive behavior that could contribute to his false beliefs.

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.

For anyone with the traits - of feeling himself victimized, of seeking to be the strongman who resolves everything, yet sees truth only through his own self and negates all other truth outside of it - is bound to become more malignant when he has power. Power then breeds an intensification of all this because the power can never be absolute power - to some extent it's stymied - but the isolation while in power becomes even more dangerous. Think of it as a vicious circle. The power intensifies these tendencies and the tendencies become more dangerous because of the power.

I'm a Brooklyn boy. I was born in Brooklyn, New York, and raised there, and spent most of my childhood there.

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.

I don't have the feeling that as a very young person I read books that absolutely made their mark on my mind.

Donald Trump both disbelieves and believes in falsehoods, so that when he did thrive on his longstanding - the claim that Obama was not born in the United States - he's crazy like a fox in manipulating it because it gave him his political entrée onto the national stage. In order to make your falsehoods powerful, you have to believe in them in some extent. And that's why we simplify things if we say that Trump either believes nothing in his falsehoods and is just manipulating us like a fox or he completely believes them.
