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.
