With the world constantly changing, Leandro Karnal seeks to stimulate new thoughts and questions, proposing themes such as how to outline a life project in the midst of the uncertainty of the future, how to face the repetition of routine, how to deal with loneliness and transform it into productive solitude, how to lead a happy life in the midst of so many disappointments and how to understand vanity. Bringing historical and philosophical culture into everyday life is the teacher's broadest task.
