Though _De Monarchia_ is much more than a footnote to the _Commedia_ and is worth study for its own sake, yet the unity which it seeks in the world is closely allied to the unity of Dante's celestial vision by which he tried to lead mankind to God. Mankind refused to be cured of its political pains by _De Monarchia_ and even ignored it in spite of Dante's secure and growing fame (there was no English translation until the late nineteenth century). But mankind also never accepted and never will accept the supreme vision of the _Commedia_. It is a beautiful poem enjoyed by the literary, and even in Italy it is valued, quite properly, as a mere work of art. The world has never paid much attention to Dante's declared purpose to bring mankind through art to God. So that in one way of regarding him, which may perhaps be his way, he failed in the _Commedia_ as he did in _De Monarchia_. The world of thinking and acting men, whose salvation Dante believed he could work by verse and prose, remains disunited and contentious, weaponed with such bitterness of heart and methods of destruction as the dreamer of _Inferno_ never dreamed. NIETZSCHE It is more than thirty years since Nietzsche's work was finished and darkness fell upon that mighty intellect. In 1917, Mr. W. M. Salter, who certainly knows the bibliography of Nietzsche, wrote: I can not make out that his influence is appreciable now--at least in English-speaking countries.... He has, indeed given a phrase and perhaps an idea or two to Mr. Bernard Shaw, a few scattering scholars have got track of him (I know of but two or three in America), the great newspaper and magazine-writing and reading world has picked up a few of his phrases, which it does not understand. The preface of Frau Foerster-Nietzsche's edition of her brother's correspondence with Wagner is dated, Weimar, 1914, and the English translation was published in 1921. Dr. Oscar Levy's preface to his selection from the five volumes of Nietzsche's correspondence,[1] published in Germany between the years 1900-1909, is dated August, 1921.
