After having analyzed influences of the past on Europe’s, Germany’s, and Berlin’s present, and having discussed concurrent present-day identities in these spaces as well as their solutions to urgent questions for our societies of the future, this final subject course lecture brings together all other topics and asks: With our historical baggage, multiple identities in society, and problems facing the future – how can we live together? What is the glue that may keep modern communities intact? Turning to philosophy as the key discipline to answer questions of this magnitude, we will introduce some answers that German philosophers have come up with since Immanuel Kant. They have shaped the development of modern German culture – and perhaps some or some combinations still hold great value today.
