I was surprised at how much I was able to comprehend (or thought I was comprehending), but I know I was only scratching the surface in terms of understanding what Deutsch was attempting to convey. Most pages took multiple reads to follow, so while 460 pages is a lengthy book, it felt closer to 700+ pages.

Intellectually provoking philosophy by an astrophysicist based on the notion that knowledge is attained and propagated through good, hard to vary, explanations. I know that makes little sense to someone unfamiliar with the text.
