Yes, yes, yes. The Beginning of Infinity is such a joy, especially if you like physics, philosophy, and politics. The book is sort of all over the place, fundamentally being an exploration into Karl Popper's ideas, and expanded by Deutsch to explore other areas. It's an argument for knowledge, humanity's future, and the infinite path in front of us. It's shamelessly optimistic.
If you're rationally-minded, read this. I don't necessarily think Deutsch is right about everything (specifically the limits of rationality), but every single chapter will give you something to think about.
