When you rule out the impossible, the rest, no matter how impossible, must be the truth. Eliminate all the impossible, even if the rest is impossible, that is the truth. If you are a precious ruin, I am willing to accept death for the public interest. If I can guarantee to destroy you, then, for the benefit of society, I will die with you. (last case) 13. What you do in this world is irrelevant. The problem is that you can make people believe what you have done. It doesn't matter what you have done in this world. What matters is how you convince others of what you have done. I never make an exception. Exceptions provide rules. I never make an exception, which would break the principle of investigation. (or I am never an exception, and the law is no exception. ) (symbol of four) 5. It is a serious mistake to theorize before there is data. In reason, one begins to adapt theory with facts, not theory with facts. It is a terrible mistake to guess (demonstrate) before there is no fact as a reference. People who feel wrong always use facts to set their own inherent guesses (arguments), instead of deducing conclusions in the right way according to the obtained facts to see if they can match the obtained facts. (Bohemian scandal) 6. One should always look for a possible choice and be prepared. This is the first rule of criminal investigation: you must find all possible ways to explain things, and then try to see if you can try to overthrow it. (Black Peter) I never guess. This is a shocking habit-the destruction of logical ability. "I never guess, that's a bad habit, destroyed my thinking ability. You saw it, but you didn't observe it. The difference is obvious. You are observing, not observing. The difference between the two is obvious. (Bohemian Scandal) When solving this kind of problems, the most important thing is to be able to reason backwards. When solving such problems, the previously assumed viewpoints must be established retroactively. Nothing is more natural than this place. Nothing is more unusual and worth studying than ordinary things. Nothing is more decisive than objective facts. Nothing can confuse people more than an obvious fact. (Bos Combi Valley Secret Case) (5) It is wrong to doubt strangeness with mystery. It is very wrong to confuse abnormal things with mystery. The more bizarre a thing is, the less mysterious it is. The more bizarre things are, the less secrets they usually contain. (Red hair club) 5. Crime is common. Logic is rare. There, you should consider logic rather than crime. Crime is common, but logic is rare. So your detailed description should be logic, not crime. (beech case) 5. Any truth is better than uncertain doubt. Any truly obtained fact is better than an uncertain guess. (Yellow-faced man) Sherlock Holmes famously said that my favorite adult Sherlock Holmes, what he said was very profound. "My creed, Watson, is based on my experience, that is to say, the meanest and scariest alleys in London will not commit more terrible crimes than this pleasant and beautiful country." There is an old proverb that when you rule out the impossible, the rest, no matter how impossible, must be true. The most important thing in detective art is to be able to distinguish what is secondary and what is important from some facts. Otherwise, your energy and attention will be scattered and you can't concentrate. " The riddle of Regatt "Strangely, typewriters can also show a person's character like handwriting." Unless both typewriters are new, no two typewriters can type exactly the same words. Nothing is more hypocritical than the obvious fact. "The Secret Case of Boscombe Valley" I decided never to have any prejudice. Where the facts point, I will obediently follow. Jealousy is a strange personality changer. Samuel johnson: "If you are tired of London, you are tired of life, because everything in life can be obtained in London." "For a great mind, nothing in the world is small. I was the last and highest court of appeal during the investigation of The Scarlet Letter (Beaton Christmas Yearbook First Edition (1887 1 1)). "Four Signs" (first edition,1February, 890, lippincott Monthly) "The mystery of life cannot be invented by any clever brain. Identity Case (First Edition) 189 1 August Riverside Magazine "A misguided doctor is a first-class criminal because he has both courage and knowledge. The Spotted Tape Case (first edition,1February, 892, Riverside Magazine) "If I give you the impression that I am too confident in my ability, or I have not spent too much energy on this case, please kindly say' noble' in my ear, I will be very grateful. "Yellow-faced Woman" (February 1st edition of Riverside Magazine 1893) "I have not wasted my life at all. If my life journey ends tonight, I can accept it with a clear conscience. Because of my existence, the air in London is very fresh. In more than 1000 cases I have handled, I believe that the power I have never mastered has been used in the wrong place. -The last question (first edition,1893,65438+February Riverside Magazine) "Life is dull and newspapers are boring. Boldness and romance seem to have disappeared in this sinful world. " -Westria Apartment (first edition, 65438+ Collier Weekly, August 0908) "Education is endless, Watson. One course after another, striving for perfection, this case is very enlightening. Red Circle Society (first edition,191March and April Riverside Magazine) "The most dangerous person in the world," Holmes said, "is a wandering and lonely woman. She is harmless and often a very useful person, but she is always a factor that leads others to commit crimes. She is helpless and has homes everywhere. She has enough money to go from one country to another, from one hotel to another. She often gets lost in the maze of remote apartments and boarding apartments. She is a chicken, lost in a world full of foxes. Once she is swallowed up, few people will miss her. The disappearance of Ms. Frances Kafax (Riverside Magazine,191112) "The knowledge of fate is elusive. If there is no response in the afterlife, then the world is a cruel joke. The Veiled Tenant (first edition,1927,65438+October Freedom) Holmes has a famous saying that my constitution is very special. I don't feel tired at work, but if I have nothing to do, I will be at a loss. I have a strange constitution. I never remember feeling tired because of work, because laziness exhausted me. I'm very upset. When I have nothing to do, I get upset. My mind resists stagnation. I pursue spiritual stimulation. I am eager to be refreshed. I can't live without thinking. What's the point of living? About women and love, no matter how good a woman is, she can never be completely trusted. Women can never be truly trusted-not the best women. But love is a sentimental thing, which is contradictory to what I think is the most important calm thinking. I will never get married, lest it affect my judgment. Love is a kind of emotional thing, and the emotional thing is opposite to the really cold reason that I think is above all else. I will never marry myself, lest my judgment be biased. Emotion can affect sober reason. Emotional quality is a forensic doctor with clear reasoning. Apart from other factors, the rest must be facts. Excluding all other factors, the rest must be the truth. Haven't I told you many times that when you remove the impossible, no matter what remains-no matter how incredible-is this the truth? How many times have I told you that when you rule out the impossible, the rest, no matter how incredible, must be true. Detective technology is-or should be-an exact science, and it should be studied in the same calm rather than emotional way. Investigation is, or should be, an exact science, and it should be treated in the same cold and inhuman way. I am never an exception. There are no exceptions to the law. I never make an exception. Exception handling rules. Winwood. Rhett has a good explanation for this problem. He believes that although everyone is an incomprehensible mystery, when human beings gather together, there is a law. For example, you can't predict a person's personality, but you can know human nature. Personality is different, but sex is eternal. That's what statisticians say. Winwood Reid is very good at this problem. He commented that although the individual is an insoluble problem, on the whole, he is a mathematical certainty. For example, you can never predict what anyone will do, but you can tell exactly how much an average will reach. Personality, but the percentage remains the same. Statistics say so. I never guess. Guess is a bad habit, which is harmful to logical reasoning. I never guess. This is a shocking habit-the destruction of logical ability.
