“The mind passes in an instant from east to west; and all the great incorporeal things resemble these very closely in speed.”

The Notebooks of Leonardo da Vinci (1883), XX Humorous Writings
Context: There will be great winds by reason of which things of the East will become things of the West; and those of the South, being involved in the course of the winds, will follow them to distant lands.

Context: Oh, East is East, and West is West, and never the twain shall meet,
Till Earth and Sky stand presently at God's great Judgment Seat;
But there is neither East nor West, border, nor breed, nor birth,
When two strong men stand face to face, though they come from the ends of the earth!

Context: What is now happening to the people of the East as of the West is like what happens to every individual when he passes from childhood to adolescence and from youth to manhood. He loses what had hitherto guided his life and lives without direction, not having found a new standard suitable to his age, and so he invents all sorts of occupations, cares, distractions, and stupefactions to divert his attention from the misery and senselessness of his life. Such a condition may last a long time.

Context: It's paradoxical that where people are the most closely crowded, in the big coastal cities in the East and West, the loneliness is the greatest. Back where people were so spread out in western Oregon and Idaho and Montana and the Dakotas you'd think the loneliness would have been greater, but we didn't see it so much.
The explanation, I suppose, is that the physical distance between people has nothing to do with loneliness. It's psychic distance, and in Montana and Idaho the physical distances are big but the psychic distances between people are small, and here it's reversed.
