The series stresses training people to be critical and think carefully about all the ideas which are presented to them. The youth series presents in simple language arguments and ideas which are so stimulating and insightful that the pupil will no longer think in the same way as before. These are ideas which change our lives. The concepts and analyses presented are derived from the author's more academic books which are being taught regularly on the university level. Thus, these books for young people also serve as professional research books for teachers.
Teachers are usually too busy to research through extensive, more complicated material.
Extensive humorous illustrations are given in the books. Humor is used throughout as a method of teaching and gaining insight. Lermann Verlag, Mainz.
