Secondary: Principia Mathematica The Principia Mathematica (often abbreviated PM) is a three-volume work on the foundations of mathematics written by Alfred North Whitehead and Bertrand Russell and published in 1910, 1912, and 1913. In 1925–27, it appeared in a second edition with an important "Introduction to the Second Edition", an "Appendix A" that replaced ✸9 and all-new "Appendix B" and "Appendix C".

Alfred North Whitehead Universal Algebra" (1898), "Principia Mathematica" (co-written with Bertrand Russell and published in three volumes between 1910 and 1913), and "An Introduction to Mathematics" (1911). The former two books were aimed exclusively at professional mathematicians, while the latter book was intended for a larger audience, covering the history of mathematics and its philosophical foundations. "Principia Mathematica" in particular is regarded as one of the most important works in mathematical logic of the 20th century. In addition to his legacy as a co-writer of "Principia Mathematica", Whitehead's theory of "extensive abstraction" is considered foundational for the branch of ontology and computer science
