I bought me this book with Volume 2, thinking naively that the content be serious and would possess a true scientific value but was soon disappointed because the author seems to have an a priori of 'official science "as it 'apelle, frustration may be legitimate in some cases but this book should rather be called "marabouts of science." However, if you buy this book, use your critical thinking by seeking ALL versions of the stories narrated in this book.
