Technology was supposed to be the servant of mankind — liberation would result from more technology. What World War One showed was how quickly this new technology could be put to use. In the end, it was the European idea of progress which became the victim of “improved technology.” The rules of warfare had changed — and with this change the 20th century plunged into what one historian has called, “the age of total war.”
.. Not outsiders but Europeans themselves invented the expression Age of Anxiety to describe what they thought was happening to them in the twentieth century. They dwelt increasingly not on the growing enlightenment of their times, as so many had done in the 18th and 19th centuries, nor on Europe’s continued greatness, but on the anxiety they felt about their existence, their culture, and their destiny. “Today,” said the Protestant theologian-philosopher Paul Tillich at mid-century, “it has become almost a truism to call our time an age of anxiety.” Tillich believed that anxiety infected even the greatest achievement of contemporary Europeans in literature, art, and philosophy. Europe, according to his account, had entered its third great period of anxiety, comparable in intensity to that of the ancient world and the Reformation.
The special form of anxiety that Tillich identified was the ANXIETY OF MEANINGLESSNESS. He traced it to the modern world’s loss of a spiritual center which could provide answers to the questions of the meaning of life.
