Alfred North Whitehead was a notable mathematician, logician, educator and philosopher. The staggering complexity of Whitehead’s thought, coupled with the extraordinary literary quality of his writing, have conspired to make Whitehead (in an oft-repeated saying) one of the most-quoted but least-read philosophers in the Western canon. While he is widely recognized for his collaborative work with Bertrand Russell on the Principia Mathematica, he also made highly innovative contributions to philosophy, especially in the area of process metaphysics . . . .
Whitehead’s decades-long focus on the logical and algebraic issues of space and geometry which led to his work on extension, became an integral part of an explosion of profoundly original philosophical work He began publishing even as his career as an academic mathematician was reaching a close. The first wave of these philosophical works included his Enquiry into the Principles of Natural Knowledge, The Concept of Nature, and The Principle of Relativity, published between 1919 and 1922. These books address the philosophies of science and nature, and include an important critique of the problem of measurement raised by Albert Einstein’s general theory of relativity. They also present an alternative theory of space and gravity. Whitehead built his system around an event-based ontology that interpreted time as essentially extensive rather than point-like . . . .
But the pinnacle of Whitehead’s metaphysical work came with his monumental Process and Reality in 1929 and his Adventures of Ideas in 1933. The first of these books gives a comprehensive and multi-layered categoreal system of internal and external relations that analyzes the logic of becoming an extension within the context of a solution to the problem of the one and the many, while also providing a ground for his philosophy of nature. The second is an outline of a philosophy of history and culture within the framework of his metaphysical scheme.
