Book excerpt: First published in 2002. This is Volume XIV of seventeen in the Library of Philosophy series on Metaphysics. Written in 1929, this book is on metaphysics and value in the intelligible world, which states that there are only two kinds of philosophies: those that find the world ultimately meaningful and intelligible and those that do not. The present book claims to belong to the first of these, and as such to be apart, however modest, of the Great Tradition in philosophy.
