Among Americans whom the German scholar met with friendly contact were Andrew Carnegie and Roosevelt. He says of the latter, “With Roosevelt I had a very spirited conversation on American idealism and its future, in which he gave proof of considerable historical knowledge.”[32] He found Americans, as a class, alert but not well informed on European affairs, especially German history. After he returned from America, he planned a trip to Japan and China, hoping to carry into the Orient his principles of idealistic philosophy; he sought coöperation of all nations in “solving problems of life.” The war interfered with this project and caused him deep depression. He tried in every way to appeal to the less materialistic traits of his people. In 1915, he wrote _The Bearers of German Idealism_, a book which sold copies by the tens of thousands and supplemented, in a way, his earlier volume, _The Historical Significance of the German People_. He found the war “the saddest moment in German history”; he felt the nations were disloyal to themselves and sentiments of honor. His daughter, a musician of rare gifts, lost her lover during the war. In his sons, one a physician and another a political economist, Eucken saw examples of many of his idealistic influences. The writings of Eucken, especially those of religious trend, have been popular in America, as well as England. Several of his essays have been collected and translated by Meyrick Booth. _In the Harper’s Library of Living Thought_ is the translation by Lucy Judge Gibson and W. R. Boyce Gibson of his _Christianity and the New Idealism_ (1909 and 1912). _The Meaning and Value of Life_ had one of the same translators; Joseph McCabe, who translated the autobiography, has rendered, also, _Socialism: an Analysis_ (1922). Among other books in constant demand at libraries are _Religion and Life_, the lectures which he gave in London, Oxford, and elsewhere, 1911, and _Ethics and Modern Thought: a Theory of their Relations_, which were the Deems lectures, delivered in 1913 at New York University. These are translated by Margaret von Seydewitz from the German manuscript. _Can We Still Be Christians?_ with its challenging title (1914) is a careful, tolerant study of historic Christianity, an advocacy of a religion which will adapt itself to the demands of daily life. Spirituality and morality must combine to form a high level of progress and the Church must become “a repository of the facts and tasks of life itself.”
