A survey of some of the most prominent nonsense circa 1958. It is good to see that some of the worst of the racial theories have been at least abraded. On the other hand Evans could not forsee vaxxers, chemtrails, and birthers so this book's gratest value may be as a yardstick to measure how far we have or have not progressed. Good condition some staining and abrasion to the cover and a gift inscription on the frontspiece, otherwise very good.
