input:  Now, answer this question: Title: A landmark book Review: Principia Mathematica is a landmark book on the elements of mathematics. This edition is the best price I have seen in decades.Both Whitehead and Russell are known for their insights into philosophy and mathematics. This book, although a mathematics book, is based upon their philosophy of how the universe works. The basic assumption of this book is that symbolic logic can be used to describe the universe. From that starting point they develop the elements of modern mathematics.This book is meant for those of us nerds who want to understand why mathematics works and how it relates to a philosophy of the universe. Note that this book is heavy on mathematical symbols (which are explained). It can be slow reading, but Whitehead and Russell's insights are stunning. Is this product review negative?
