The Modern Library placed it 23rd in a list of the top 100 English-language nonfiction books of the twentieth century.INTRODUCTION THe mathenratical logic which occupies Part I of the present work has been constructed under the guidance of three different purposes. But as we advanced, it became increasingly evident that the subject is a very much larger one than we had supposed." a second volume of Principles of Mathematics. PM states: "The present work was originally intended by us to be. PM is not to be confused with Russell's 1903 Principles of Mathematics. One of the main inspirations and motivations for PM was the earlier work of Gottlob Frege on logic. For any set of axioms and inference rules proposed, either the system must be inconsistent, or there must in fact be some truths of mathematics which could not be deduced from them. However, in 1931, Gödel's incompleteness theorem proved that PM, and any other attempt, could never reach this goal. The authors believed that such a project could be done. This ambitious project is of great importance in the history of mathematics and philosophy. The book was an attempt to describe a set of axioms, inference rules and law of noncontradiction in symbolic logic from which all mathematical truths could in principle be proved. In 1927, it appeared in a second edition with an important Introduction to the second edition, and different notes at the end. The Principia Mathematica is a three-volume work on the foundations of mathematics by Alfred North Whitehead and Bertrand Russell.
