Query: Highest praise for a marvellous book

At one point in my life I worked 'troubleshoting', solving problems that often were descrbied as 'unresolvable' - usually because people believed that when you eliminated the impossible you ended up with the necessary. But I was struck how easy it is to 'hypnotise' oneself into mistakes as to what is 'impossible'. The liklihood of error from mistakenly acceepting false equivalences seemed to me the root of almost all the problems that stumped or misled the really talented, often brilliant, and skilled people I helped. This is the first book I have read that made me feel the author had 'been' there or at least caught 'how it was' to be at the heart of solving such puzzles. I really feel the French expression, chapeau, is merited - in spades. I also found this book first published almost a century ago astonishingly undated in how it felt to me.
