Anyone who leads people professionally should employ more than just common sense. What is sought is a way of thinking that constructs complex relationships in dimensions that go beyond the tried and tested. In six excursions to various regions, the meaning of this is explored. The underlying experience is that reading theories about thinking does not lead to progress; one must immerse oneself in the flow of thought. Therefore, these excursions not only summarize what others have published but also provoke independent thinking. The textbook is aimed at students and lecturers in education and special education, as well as interdisciplinary individuals in leadership positions.
