Friedrich Nietzsche appears to me the most interesting writer in German literature at the present time. Though little known even in his own country, he is a thinker of a high order, who fully deserves to be studied, discussed, contested and mastered. Among many good qualities he has that of imparting his mood to others and setting their thoughts in motion. During a period of eighteen years Nietzsche has written a long series of books and pamphlets. Most of these volumes consist of aphorisms, and of these the greater part, as well as the more original, are concerned with moral prejudices. In this province will be found his lasting importance. But besides this he has dealt with the most varied problems; he has written on culture and history, on art and women, on companionship and solitude, on the State and society, on life's struggle and death.
