The core questions of philosophy about the origin of the world and people, the distinction between good and evil, and the meaning of life - these questions keep us all busy. In this introduction to philosophy, these three questions lead our journey. You want to understand the world and man. Then you try to acquire an outlook on the proper course of action. Perhaps you especially hope to gain insight into the meaning of your own life. And our society, as well, repeatedly collides with questions of its economic, social, and ecological limits. Again and again, philosophy is the necessary condition for finding answers in a rational manner to the demands for in-sight, outlook, and the search for meaning. This is a fascinating story of more than 2,500 years of thought, where the reader might feel inspired to add his or her own responses to the most important personal and social questions. But also to ask new questions - the point of philosophy.
