For both the rich and the poor, life is dominated by an ever growing current of problems, most of which seem to have no real and lasting solution. Clearly we have not touched the deeper causes of our troubles. It is the main point of this book that the ultimate source of all these problems is in thought itself, the very thing of which our civilization is most proud, and therefore the one thing that is "hidden" because of our failure seriously to engage with its actual working in our own individual lives and in the life of society.
