“We may enjoy our room in the tower, with the painted walls and the commodious bookcases, but down in the garden there is a man digging who buried his father this morning, and it is he and his like who live the real life and speak the real language.”

The Paris Review interview (2010)
Context: The need for romance is constant, and again, it’s pooh-poohed by intellectuals. As a result they’re going to stunt their kids. You can’t kill a dream. Social obligation has to come from living with some sense of style, high adventure, and romance. It’s like my friend Mr. Electrico. … he was a real man. That was his real name. Circuses and carnivals were always passing through Illinois during my childhood and I was in love with their mystery. One autumn weekend in 1932, when I was twelve years old, the Dill Brothers Combined Shows came to town. One of the performers was Mr. Electrico. He sat in an electric chair. A stagehand pulled a switch and he was charged with fifty thousand volts of pure electricity. Lightning flashed in his eyes and his hair stood on end. … Mr. Electrico was a beautiful man, see, because he knew that he had a little weird kid there who was twelve years old and wanted lots of things. We walked along the shore of Lake Michigan and he treated me like a grown-up. I talked my big philosophies and he talked his little ones. Then we went out and sat on the dunes near the lake and all of a sudden he leaned over and said, I’m glad you’re back in my life. I said, What do you mean? I don’t know you. He said, You were my best friend outside of Paris in 1918. You were wounded in the Ardennes and you died in my arms there. I’m glad you’re back in the world. You have a different face, a different name, but the soul shining out of your face is the same as my friend. Welcome back.
Now why did he say that? Explain that to me, why? Maybe he had a dead son, maybe he had no sons, maybe he was lonely, maybe he was an ironical jokester. Who knows? It could be that he saw the intensity with which I live. Every once in a while at a book signing I see young boys and girls who are so full of fire that it shines out of their face and you pay more attention to that. Maybe that’s what attracted him.
When I left the carnival that day I stood by the carousel and I watched the horses running around and around to the music of “Beautiful Ohio,” and I cried. Tears streamed down my cheeks. I knew something important had happened to me that day because of Mr. Electrico. I felt changed. He gave me importance, immortality, a mystical gift. My life was turned around completely. It makes me cold all over to think about it, but I went home and within days I started to write. I’ve never stopped.
Seventy-seven years ago, and I’ve remembered it perfectly. I went back and saw him that night. He sat in the chair with his sword, they pulled the switch, and his hair stood up. He reached out with his sword and touched everyone in the front row, boys and girls, men and women, with the electricity that sizzled from the sword. When he came to me, he touched me on the brow, and on the nose, and on the chin, and he said to me, in a whisper, “Live forever.” And I decided to.

Context: I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children; whose work serves the earth he lives on and from and with, and is therefore pleasurable and meaningful and unending; whose rewards are not deferred until "retirement," but arrive daily and seasonally out of the details of the life of their place; whose goal is the continuance of the life of the world, which for a while animates and contains them, and which they know they can never compass with their understanding or desire.
