On this day, 89 years ago, May 8, 1936 (March 18, 1936 in the lunar calendar), the prophet who held the view of decline passed away. On May 8, 1936, Oswald Spengler, a German historian and philosopher who was world-famous for his book "The Fall of the West", died at the age of 55. He demonstrated that the development of history also follows the natural laws of biological growth. He believed that every culture was doomed to decline. According to Spengler, Western culture is in the twilight and will become a victim of mass production and materialism. Because he did not accept Nazi racist theories, he lived a lonely life after Hitler's War.
