“Holmes had cultivated the ability to still the noise of the mind, by smoking his pipe and playing nontunes on the violin. He once compared this mental state with the sort of passive seeing that enables the eye, in a dim light or at a great distance, to grasp details with greater clarity by focusing slightly to one side of the object of interest. When active, strained vision only obscures and frustrates, looking away often permits the eyes to see and interpret the shapes of what it sees. Thus does inattention allow the mind to register the still, small whisper of the daughter of the voice.”

“When you come to a fork in the road, be still, and see with your mind's eye. There you find the clarity you seek.”

“Abstraction allows man to see with his mind what he cannot see physically with his eyes.”

“Sight is seeing with the eyes; vision is seeing with the mind.”

“In external ways Pierre had hardly changed at all. In appearance he was just what he used to be. As before he was absent-minded and seemed occupied not with what was before his eyes but with something special of his own. The difference between his former and present self was that formerly when he did not grasp what lay before him or was said to him, he had puckered his forehead painfully as if vainly seeking to distinguish something at a distance. At present he still forgot what was said to him and still did not see what was before his eyes, but he now looked with a scarcely perceptible and seemingly ironic smile at what was before him and listened to what was said, though evidently seeing and hearing something quite different. Formerly he had appeared to be a kindhearted but unhappy man, and so people had been inclined to avoid him. Now a smile at the joy of life always played round his lips, and sympathy for others shone in his eyes with a questioning look as to whether they were as contented as he was, and people felt pleased by his presence.”

“It was then that Maxim looked at me. He looked at me for the first time that evening. And in his eyes I read the message of farewell. It was as though he leant against the side of a ship, and I stood below him on the quay. There would be other people touching his shoulder, and touching mine, but we would not see them. Nor would we speak or call to one another, for the wind and the distance would carry away the sound of our voices. But I should see his eyes and he would see mine before the ship drew away from the side of the quay.”
