You start reading this book and is tied. The plans prepared by the authors of theses are provocative, the scientific mainstream completely counter strike, and you burn it the evidence for these theories about it. But soon begins disillusionment. Although many data at hand the own theses are confirmed and other theories are disproved, the reading pleasure sounds relatively quickly. The explanations are unfortunately written far too long-winded. Mostly we know after a few sentences on what points the following chain of reasoning is stüzen and can from that moment on the scroll next 10 pages without much loss of information. The great strength of this book lies, however, is to make clear to the reader that can not be simple and logical explanations of social phenomena usually evidenced by data. It encourages the reader to develop their own point of view and to seek explanations behind, probably possible at first glance, very devious appearing events.
