Arthur Conan Doyle Quotations

-Mediocrity knows nothing higher than itself, but talent instantly recognizes genius.

-It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth.

-I never guess. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
Sir Arthur Conan Doyle
