I was hoping that, since this book was written by a prominent scientist, it would avoid straying too far into the kinds of groundless speculation and assertion that often characterize contemporary discussions around creativity. Unfortunately however, I found this book to be full of all kinds of unsubstantiated nonsense and presumptuous generalisations with very little, if any, foundation in research or empirical evidence. If you are looking to gain some clear insights into the nature of creativity as opposed to a litany of philosophical ramblings then I wouldn't recommend reading this book. To quote Bohm: "it is up to each person to make the first step for himself, without following another, or setting up another as his authority for the definition of what creativity is and for advice on how it is to be obtained." Quite.
