In contrast to open societies, Deutsch also discusses static societies which do not make progress.

If you are narrowly interested in physics you should read it for the chapter explaining what the multiverse is like -- and when you do you may also be challenged by the chapter on bad philosophies of science and intrigued by the chapter on the reality of abstractions. If you are only interested in math and computation, you'll want to read the chapter on AI, but you'll also enjoy the chapter about the concept of infinity. If you're an artist you'll appreciate the discussion of the beauty of flowers, and the wit of the Socratic dialog. Whatever the case may be, the philosophy running throughout has universal interest.
