This methodologically oriented chapter starts by defining military concepts: strategy, logistics, tactics, operations. Sun Tzu himself did not distinguish between strategy and tactics, so this is a modern lens on Sun Tzu’s thinking. Next, a standardized five-part format is introduced, to be used to provide uniform structure for the fourteen chapters analyzing fourteen major Sun Tzu themes: (a) list of Sun Tzu passages chosen to illustrate a given theme (just a list, not the passages themselves); (b) Sun Tzu (1) analysis of Sun Tzu’s ideas pertaining to that theme; (c) further Sun Tzu (1) analysis of facets of the given theme that conditions of war and politics in Sun Tzu’s time suggest that Sun Tzu might plausibly have discussed, yet did not discuss; (d) Sun Tzu (2) and (3) "frontiers" of the theme, generalizing Sun Tzu’s relevant ideas in selected Sun Tzu (2) and (3) directions; (e) passages listed in Part (a) (in Griffith’s translation), often with brief commentary . The chapter ends by introducing notational conventions used throughout this study to refer to Griffith verses and passages.

Theme #9 is about exploiting dynamics already present in a situation to advance one’s interests. Many Sun Tzu ideas find a place here, reflecting Sun Tzu’s keen appreciation of war’s larger context (Passage #1.1) conjoined with the inherently dynamic quality of Sun Tzu’s core concept of shi.

There are two Sun Tzu verses which, by Sun Tzu’s own affirmations, may be seen as summations of the active ingredient of his way of war. One is Theme #6’s centerpiece verse III.4 (Passage #6.1).

Often regarded as the oldest surviving work on strategy, the Sun Tzu text has influence in many quarters today. This study organizes Sun Tzu’s ideas under fourteen thematic headings. It also clarifies Sun Tzu’s limitations and blind spots. Building on Brigadier General Samuel B. Griffith, USMC (Ret.)’s translation, this study analyzes Sun Tzu from three standpoints: Sun Tzu (1), Sun Tzu’s ideas in their original Warring States Chinese context; Sun Tzu (2), Sun Tzu’s ideas applied to warfare in a military sense in other times and places; Sun Tzu (3), generalizations of those ideas, including to cyber warfare and other twenty-first-century strategic competitions. Whereas Sun Tzu (1) analysis addresses ways in which the text is a product of its times, intertwined with traditional Chinese cultural milieux, Sun Tzu (2) and (3) analyses, often building on analogical thinking, map universalistic aspects of Sun Tzu’s insights into war and conflict, strategy, logistics, information, intelligence, and espionage. Those analyses also identify ways in which Sun Tzu’s thinking has relevance to gaining strategic advantage in twenty-first-century conflicts.

At the heart of the versatility of Sun Tzu’s thinking – and a basic reason it is so extraordinarily conducive to digital age applications – stands its unswerving emphasis on the pivotal importance of information as a resource for strategic actors.

“Interface” in present usage is a modern concept whose roots lie in physical science and engineering disciplines. For serendipitous reasons it happens to work well as a conceptual tool for structuring Sun Tzu’s approach to leadership topics, starting with the political level (the ruler) and extending in the military realm down to the level of common soldiers. That is the focus of Theme #13.
