This book, although quite interesting seems to be written mostly not to explain the subject to the reader, but to confuse the reader with lots of irrelevant details. The author seems to lack the ability to stick to his point, and drifts away from it more than once in most chapters. The structure of the book looks very appealing by the mixture of two questions. But as it turns out, the holistic/individual & explaining/understanding distinctions are not stricly seperated, or usefully connected.
Some comparisions made in this book (for example, the different book of Durckheim are compared in a quite messy way) are in my opinion just their because the author wanted to show off how much he has read.
Alltogether I think this book is really a waste of paper, ink and time. So I would recommend NOT to buy this book; try to look for a book by an other author when you're interesseted in this subject.
