Aurel Thomas Kolnai (Budapest, 1900) studied Philosophy, Economics and History at the University of Vienna. In 1926 he finished his doctoral thesis, The ethical value and reality, and that same year he converted to Catholicism influenced by Chesterton's writings and phenomenology, which aroused a special interest in the author. During the 1930s, Kolnai promoted his journalistic career denouncing the abuses of fascism, a subject on which the war against the West (1938), the work that earned him fame, is about. His Jewish origin forced him to flee to America after the outbreak of World War II. In 1955 he returned to Europe. He lives in the United Kingdom, where he will live until his death in 1973. Kolnai was an extraordinarily versatile thinker, able to write in five different languages, on different philosophical currents and in very different intellectual environments. That without ever losing the sharpness, ingenuity and originality that characterized him.
