When approaching a complex problem, it is often difficult to keep in mind the many factors involved and to retain a clear view of how they relate to each other. Edward de Bono has built his reputation on providing thinking tools that are very simple to use and yet are powerful in their effect. In this book he puts forward a new method for problem solving. de Bono contends that traditional logic is static, based on the solid foundation of "is" and identity. In contrast to this traditional "Rock Logic", he proposes "Water Logic" which is based on "to" and the flow of the mind: "What does this lead to?" as opposed to "What is this?" This new logic is surprisingly easy to learn and to use, and results in a visual "flowscape", which allows you to layout and then look at your thinking. There is also an abridged version of Water Logic available at http://bit.ly/water-logic
