While this is only a preface, Professor Maritain has covered a world far above the heads of most of our customers. Every one interested in metaphysics or philosophy will acclaim it as the great contribution it is. It is a book for stock and for immediate sales. Put it in a conspicuous place, -- the window, a front table, etc. -- not in the religious corner, since many people will want it to whom you might not mention it. A must for schools, colleges and libraries.
