There is a rather diverse selection of topics, some of them I disagreed with, but then this was published 1985, and I have to say that part of the disagreement, is changes that have occurred since that time. Other sections I had a hard time reading. I have tried to read this before and it's a big book... And I think part of what makes it hard, is that the tone/topic can change and become "boring" for a longer period than is really comfortable to really read through. It was a nice deck reading book where I'd read a bit, take a break and get back to a bit later in the nice weather.
