An original view of interdisciplinary thinking and its applications is given in this book. It aims to help the reader develop a contextual way to understand and act in complex situations. The book is based on a G-type principle: heterogenetic, interactive and pattern-generating. Each chapter is not only interdisciplinary, but also contextual and relational. They correspond to each of the six ways of cultivating contextual understanding. Five of the chapters give concrete examples; three of them center on examples from business management. This is because business management has become a frontier of complexity requiring contextual thinking; it is useful epistemologically to those in the humanities, social and natural sciences. The sixth chapter theoretically summarizes all the concrete examples.
