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 was an Englishman by birth and a mathematician by formal education.
