It is quite possible--overwhelmingly probable, one might guess--that we will always learn more about human life and personality from novels than from scientific psychology
If we understood, as we do not, the physical bases for intellectual structures, I have little doubt that we would find structures in the brain for social interactions, or language, or analysis of personality - a whole variety of systems developed on the basis of a specific biological endowment.
If you read people like say Bruce Blair one of the leading, most sober, knowledgeable specialists, he says, look, [Donald Trump] statements are all over the map, but his personality is frightening, he's a complete megalomaniac.
With regard to nuclear weapons, it's kind of hard to say. [Donald Trump] is said lots of things. The national security experts are terrified. But they're more terrified by his personality than by his statements.
