After having enjoyed reading this author's "The Use of Lateral Thinking", I saw this book and thought I would read it. There are several reasons why I didn't enjoy this as much as the other book: it contains too many examples and padding out, it is patronising, and the idea behind the book is not great.
The premise of the book is that there is another type of logic, other than the standard formal logic (which the author insists on calling "rock logic" throughout the book), and this other type is "Water Logic". Water logic doesn't involve the use of logic, instead it requires us to do a sort of brain storm, to connect up the associated concepts, and then decide what "flows" where. This is meant to help us locate where the problems are, which concepts are important, and what needs to be changed. So, he provides us with a system of doing all this, and it isn't a terribly bad system, I can imagine it working. But, I think most people would be able to work out the sort problems that this system is suited to, without using the system, and the book does have the dubious air of a gimmick about it.
Also, this system could not do anything that normal logic could not do, provided the user had a good mind, but it does give an idiot proof way in which people who are not that clever could formulate and go about solving problems. It doesn't hurt to have different ways of thinking about things, and this book is not worthless, I just would not recommend it as highly as the other book from this author that I have read. ( )
