"Very enjoyable, but barely scratches the surface of Wittgenstein's life, work, and character (understandably). And it's a long book."

Doesnt have much maths in it. But a fantastic book nonetheless. Duffy does not claim the work to be biography, but rather a work of fiction based around events of Wittgenstein's life.

What is quite remarkable about this book is the literary style. The psychological penetration into the mind of the characters is particularly vivid. As a reader you really come to see the world as the characters do, and how their world views conflict deeply and somewhat tragically. It is a dense book, but worth the effort. One of my personal favourites.
