Sherlock Holmes: The Complete Works

Sir Arthur Conan Doyle


  • Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
  • “It is a capital mistake to theorize before you have all the evidence. It biases the judgment.”
  • “Do you remember what Darwin says about music? He claims that the power of producing and appreciating it existed among the human race long before the power of speech was arrived at. Perhaps that is why we are so subtly influenced by it. There are vague memories in our souls of those misty centuries when the world was in its childhood.”
