Peace, freedom and justice – who doesn’t dream of them? They are the foundation on which the prosperity and democracy of the Western world rest. But these values are in danger and are increasingly being called into question, even in the “West”. In three episodes, science journalist Mirko Drotschmann explains how our ideas of peace, freedom and justice have changed over the course of history and how they have made the world a better place. In the Think Lab, actors Rosalie Thomass and Daniel Sträßer tackle the most pressing issues of our time and explain the most important basic concepts.
