There is nothing as deceptive as an obvious fact.
Sir Arthur Conan Doyle
My mind rebels at stagnation. Give me problems, give me work, give me the most abstruse cryptogram, or the most intricate analysis, and I am in my own proper atmosphere. I can dispense then with artificial stimulants. But I abhor the dull routine of existence. I crave for mental exaltation.
Sir Arthur Conan Doyle
... when you have eliminated the impossible, that which remains, however improbable, must be the truth.
Sir Arthur Conan Doyle
I can never bring you to realize the importance of sleeves, the suggestiveness of thumb-nails, or the great issues that may hang from a boot-lace.
Sir Arthur Conan Doyle
Where there is no imagination there is no horror.
Sir Arthur Conan Doyle
It is not the mountain we conquer, but ourselves.
