The present volume, as well as the companion volume of Readings, arose out of a practical situation. Twenty-two years ago, on entering Stanford University as a Professor of Education and being given the history of the subject to teach, I found it necessary, almost from the first, to begin the construction of a Syllabus of Lectures which would permit of my teaching the subject more as a phase of the history of the rise and progress of our Western civilization than would any existing text. Through such a study it is possible to give, better than by any other means, that vision of world.
