Pan, London, 1967, 11^th pr.  XP24.  MMPB, 189 pages.  Good; wraps show edge and cover wear, a few creases and marks, short tear at lower front spine edge; binding sound.  Price stamp on 1^st page; remainder of interior clean and unmarked with tanned pages.  ‘The author believes that psychological factors often dangerously distort correct thinking.  He shows, for instance, how the use of emotional words can obscure facts, and how fallacies in argument can often mislead an unwary audience.  He lists 38 dishonest tricks commonly used in argument, with methods of overcoming them, and ends with an imaginary discussion between a businessman, a clergyman and a professor which illustrates these pitfalls.’ (from rear wrap)
