Stratagems - that is what we call war ruses but also ruses in general. They can decide victory or defeat. We are all familiar with well-known war ruses. Just think of the Greek story of the Trojan horse. These days, we think of a "Trojan horse" mostly in connection with criminal computer hacking. We then have to ask: "How does one think up stratagems?" To do so, one must have competency in creative and systemic thinking. This book explains the value and meaning of these ways of thinking for the creation of stratagems. Readers will learn - How to think of the term "stratagem" - What kinds of stratagems one might find (e.g. from antiquity, the "Stratagemata" of Frontin) - What creative and systems thinking is and how it expresses itself in the development of ruses - How one might go about thinking up stratagems This book is meant for everyone who handles social conflict as well as those with an interest in creative and systems thinking.
