"A’s papers contain a number of attempts to formulate an aesthetic philosophy of life. A single, coherent, aesthetic view of life can scarcely be carried out. B’s papers contain an ethical view of life. As I let this thought sink into my soul, it became clear to me that I might make use of it in choosing a title. The one I have selected precisely expresses this. The reader cannot lose very much because of this title, for while reading the book he may perfectly well forget the title. Then, when he has read the book, he may perhaps reflect upon the title. This will free him from all finite questions as to whether A was really convinced of his error and repented, whether B conquered, or if it perhaps ended by B going over to A’s opinion. In this respect these papers have no ending."
