At a time like the present, when the ever increasing complexity of life leaves one scarcely a moment for reading, when the map of Europe has undergone radical alterations, and is on the eve, very probably, of undergoing others more drastic still, when so many new and threatening problems are arising on every side, you will allow me to suggest that one is entitled to ask that a writer should be something else than a fine intellect which makes us forget, amid otiose and byzantine discussions of the merits of pure form, that we may be overwhelmed at any moment by a double tide of barbarians, those from without and those from within our borders.
