This little book, written during the last months of peace, goes to press in the first weeks of the great war. Many will feel that in such a time of conflict and horror, when only the most ignorant, disloyal, or apathetic can hope for quietness of mind, a book which deals with that which is called the "contemplative" attitude to existence is wholly out of place. So obvious, indeed, is this point of view, that I had at first thought of postponing its publication.
