Philosophy is, etymologically and in fact, the love of wisdom. It is interested in the big questions: What is the nature of the world? What is the essence of the human? What are the conditions and possibilities of knowledge? What is ethically correct action? What is the purpose of life?
 
This book about the historical development of philosophy highlights the process of philosophical thinking. The form of a notebook was deliberately chosen to represent both the multifaceted nature of the fields of inquiry and their connecting unity, the “longing for knowledge and truth”.
