White Flash On North Tower Impact, The BAE Proximity Fuze, Sherlock Reasons Backwards
Gleaned from the stories of Sherlock Holmes written by Sir Arthur Conan Doyle are these quotes from Mr. Sherlock Holmes regarding his techniques and methods for solving mysteries and crimes using deductive reasoning.
“In solving a problem of this sort, the grand thing is to be able to reason backwards. That is a very useful accomplishment, and a very easy one, but people do not practise it much. In the every-day affairs of life it is more useful to reason forwards, and so the other comes to be neglected. There are fifty who can reason synthetically for one who can reason analytically…Let me see if I can make it clearer. Most people, if you describe a train of events to them, will tell you what the result would be. They can put those events together in their minds, and argue from them that something will come to pass. There are few people, however, who, if you told them a result, would be able to evolve from their own inner consciousness what the steps were which led up to that result. This power is what I mean when I talk of reasoning backwards, or analytically.”
