This one is good and interesting, but keeps failing to do more.
You see, Exact Thinking in Demented Times is about the Vienna Circle, a group of philosophers, mathematicians, economists, and physicists who roughly made up the core founders of (now mostly… I don’t want to say discredited, because that’s not fair, but let’s just say that it’s not something many people identify themselves as these days) logical positivism.
While it does a good job of showing how physics, in particular, played a fascinating cross-pollination role in this philosophical school, it doesn’t really tell us much about the actual philosophy. It also spends too much time on people who weren’t really logical positivists nor participated in the meetings on the Vienna Circle (I’m looking at you, Wittgenstein!).
And aspects of the depiction of the historical milieu seem a little half-baked. For example, I am assuming that the ‘demented’ references mainly to Nazism and fascism, but somehow, until the last quarter of the book (in a way that feels tacked on), he manages to elude the urge to talk about this key aspect of the time period.
So we neither get an exact picture of their thinking nor a good view of demented Nazis.
Which isn’t to dismiss it entirely. It was a worthwhile read, just not what it could have been.
And it did inspire me to try and dig up some Carnap make another go at reading him after some abortive efforts in college (I used to study at a table very near the shelf where The Logical Syntax of Language could be found, taunting me).
