Arthur Conan Doyle — "We are all pilgrims on a journey."

"Several incidents in my life have convinced me of spiritual interposition – of the promptings of some beneficent force outside ourselves, which tries to help us where it can."

"One must not be too systematic in this world."

"The most dangerous condition for a man or a nation is when his intellectual side is more developed than his spiritual. Is that not exactly the condition of the world today?"

"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."

"Man is an ape, and woman is a cat."
