Strategy literature is abundant, but there is no book that shows you how to actually think strategically. The Forgotten Vocabulary of Strategy (Vol. 1 and Vol. 2) fills this gap. For the first time it reveals the ways of thinking, acting and teaching of successful Western and Asian strategists as well as Arab and Indian mirrors for princes and looks 2500 years into the past. In its essence, the book demystifies the 12 most renowned strategic approaches, distills them into a holistic system and thus enables the reader to develop a universally strategic mind through a scientifically founded process. STRATEGISTS THINK IN PATTERNS These patterns, also called Strategic Principles, are based on the rules of the social world. They are learnable and limited in number. Decision-makers, project managers as well as specialists and leaders of all levels and areas need this universal, practical knowledge, as they are involved in social interaction every day. These two textbooks are therefore aimed at all strategy teachers who are looking for a timeless, interdisciplinary and cross-cultural strategy perspective. Practising autodidacts will also benefit, since the complete vocabulary of strategy, consisting of 153 literarily described principles, is presented in a systematised format. The principle-oriented strategy teaching - PriOri - enables the strategist to master not only the rational but also the irrational level of the mind. PriOri provides a fundamental insight into the functioning of the human mind and reveals which evolutionary mechanisms help strategic action in social interaction to succeed. By successively learning the principles, the reader develops social strategic competence - the foundation of common sense. It enables the reader to reduce complexity, simultaneously analyse interaction, avoid wrong decisions and ultimately master his daily work more calmly and efficiently.
