French prose and French poetry had interested me during so many years that when Mr. Gosse invited me to write this book I knew that I was qualified in one particular--the love of my subject. Qualified in knowledge I was not, and could not be. No one can pretend to know the whole of a vast literature. He may have opened many books and turned many pages; he cannot have penetrated to the soul of all books from the Song of Roland to Toute la Lyre. Without reaching its spirit, to read a book is little more than to amuse the eye with printed type.
