The story of humankind is a history of ideas. Beginning with the resurrection of Greek and Roman thought in the medieval period, and later during the Renaissance and Enlightenment, western civilization has been driven by ideas. Within this framework, no ideological movement has had a more profound impact on Europe than the Reformation. In the late medieval period, when life was short and existence a struggle, primary allegiance was to religion rather the nation state. The dramatic changes that began when Martin Luther proclaimed his Ninety-five Theses in Wittenberg in 1517 were of a different order to anything that had gone before. The Christian world broke apart, and the nature not just of religion but of thought, culture, and society all changed. The course of history down to our own time has been shaped by this revolution. We will explore the origins and consequences of this movement using as our source: The Reformation: A History by Diarmaid MacCulloch (Viking, 2004). Join us for what is sure to be a very interesting and provocative discussions.
