This was a captivating book on math, philosophy, and our understanding of the world. The stories from the author were a great addition, recounting people he met through his travels who gave him insights into mathematics. Some stories could have been shortened or removed but they rounded out the book nicely overall. I found some of the appendices poorly explained and even coming from a mathematical background I couldn't follow some of it. But all in all an insightful and fun book for anyone interested in math, philosophy, and epistemology!
