“My dear Watson," said [Sherlock Holmes], "I cannot agree with those who rank modesty among the virtues. To the logician all things should be seen exactly as they are, and to underestimate one's self is as much a departure from truth as to exaggerate one's own powers.”
― Arthur Conan Doyle, The Adventure of the Greek Interpreter (The Memoirs of Sherlock Holmes, #9 )
