During this period, he read avidly and was influenced by the works of Oswald Spengler, Fyodor Dostoyevsky, and Houston Stewart Chamberlain, the British-born German writer whose book The Foundations of the Nineteenth Century (1899) was one of the standard works of the extreme right in Germany. He also began to study the "social question" and read the works of Karl Marx, Friedrich Engels, Rosa Luxemburg, August Bebel, and Gustav Noske. According to German historian Peter Longerich, Goebbels's diary entries from late 1923 to early 1924 reflected the writings of a man who was isolated, preoccupied with "religious-philosophical" issues, and lacked a sense of direction. Diary entries of mid-December 1923 forward show Goebbels was moving towards the Völkisch nationalist movement.
