Many days have elapsed, my dear friend, since our childhood, but they have passed away without effecting any alteration in the affectionate feelings we then entertained. In memory of an intimacy of heart and mind which has never known a cloud, it is very pleasant to me to write your name at the beginning of that one of my books which you preferred to all the rest. It is further the book in which I have stated with most sincerity what I think concerning some of the essential problems of the modern life of our day.
