Saturday marks the 164th birthday of Sherlock Holmes, the high functioning sociopath. And even now, the world-famous detective continues to baffle minds. Sherlock Holmes fanatics believe Jan. 6, 1854, was the day he was "born," on paper, of course.

Holmes has inspired a universe of portrayals in books and popular culture, and the detective's legacy can be summed up with the Museum of London's description of him: "The Man Who Never Lived and Will Never Die."

According to the published stories, which first appeared in the Strand Magazine in 1891, Holmes practiced as a consulting detective between the years 1881-1904, while he resided at 221b Baker Street with his friend and colleague Doctor John H. Watson.

Holmes has been presented to us in various avatars throughout the years. While Robert Downey Jr. portrayed Holmes in movies, Benedict Cumberbatch stole the show in the T.V. series and made us fall in love with his character. In a spin-off from the original concept, Jonny Lee Miller also played the character Sherlock in a series known as "Elementary."

And as we celebrate the birthday of this man today, here are some quotes and sayings, collected from and by the "high functioning sociopath" that will provide an insight into his mind.

That is why I have chosen my own particular profession, — or rather created it, for I am the only one in the world." — The Sign of Four
