Your method of traveling, especially,—to live along the road, citizens of the world, without haste or petty plans,—I have often proposed this to my dreams, and still do. But the fact is, I cannot so decidedly postpone exploring the Farther Indies, which are to be reached, you know, by other routes and other methods of travel. I mean that I constantly return from every external enterprise with disgust, to fresh faith in a kind of Brahminical, Artesian, Inner Temple life. All my experience, as yours probably, proves only this reality.
Henry David Thoreau (1817–1862), U.S. philosopher, author, naturalist. Letter, August 14, 1844, to Isaac Hecker, in The Writings of Henry David Thoreau, vol. 6, p. 406, Houghton Mifflin (1906).
Father Hecker (a sometime Transcendentalist and future founder of the Paulist order) had just converted to Catholicism, and was proposing that Thoreau join him on an ascetic pilgrimage to Europe.
