This is a collection of many of Whitehead's papers that are scattered elsewhere. It was the penultimate book he published, and represents his mature thoughts on many topics. Philosophical Library has done a great service by publishing a representative collection of his writings on the subjects of Philosophy, Education and Science. The portion on Philosophy includes five papers: ';Immortality', ';Mathematics and the Good', ';Process and Reality', ';John Dewey and His Influence' and the ';Analysis of Meaning.' The first three chapters consist of Whitehead's personal reflections illumined by flashes of his lively humor. They are picturesque and amusing. The remainder of the book consists of chapters on Philosophy, Education, and Science. They cover in depth his positions on many scientific and philosophical matters in an extraordinarily unified way. The final section of the book is devoted to excellent surveys of Geometry and Mathematics as well as a paper on Einstein's theories.
