|summary=A chatty and warm look at just where mankind went wrong in its ideas.

}}

Mankind has often had some quite ridiculous ideas. Once upon a time people deemed it sensible for doctors to go from an autopsy room to help give birth without washing hands in between – who'd have thought it might be beneficial? Those self-same medical scientists were within generations going to extol the virtues of cocaine and opium as harmless boosts to medicine, and in the interim proudly induce enemas of tobacco smoke – the early version of colonic irrigation so beloved of some dodgy ex-Princess-type people. Outside the medical room, there was once the notion that the Earth was flat – although not as might be popularly believed, a regular idea in Columbus's days, but certainly at times before then. The spread of man's idiocy where wrong, faulty and dodgy science is concerned, and the history of all the false ideas, is touched on in this fascinating volume.
