Many heterosexual marriages are childless; many with children break up: they are no guarantee that children will be raised in a house with two parent… - Rebecca Solnit

Suddenly I came out of my thoughts to notice everything around me again-the catkins on the willows, the lapping of the water, the leafy patterns of the shadows across the path. And then myself, walking with the alignment that only comes after miles, the loose diagonal rhythm of arms swinging in synchronization with legs in a body that felt long and stretched out, almost as sinuous as a snake…when you give yourself to places, they give you yourself back; the more one comes to know them, the more one seeds them with the invisible crop of memories and associations that will be waiting for when you come back, while new places offer up new thoughts, new possibilities. Exploring the world is one the best ways of exploring the mind, and walking travels both terrains.

When I think of the artist Yves Klein, I think of those absolutists who preceded him by a generation or two, those who vanished, think of the boxer and Dadaist poet Arthur Cravan who in 1918 was supposed to leave Mexico to meet his new wife in Argentina but was never seen again; of Everett Ruess, the bohemian who might have become an artist or writer had he not disappeared into the canyons of Utah at the age of twenty in 1934, leaving behind a final signature carved into the rock: "Nemo" or "no one"; of the aviator Amelia Earhart who disappeared over the Pacific in 1937; of the pilot Antoine de Saint Exupéry who left behind several lapidary books before his plane too disappeared, in 1944, in the Mediterranean. They were all saddled with a desire to appear in the world and a desire to go as far as possible that was a will to disappear from it. In the ambition was a desire to make over the world as it should be; but in the disappearances was the desire to live as though it had been made over, to refashion oneself into a hero who disappeared not only into the sky, the sea, the wilderness, but into a conception of self, into legend, into the heights of possibility.

Questions about happiness generally assume that we know what a happy life looks like. Happiness is often described as the result of having a great many ducks lined up in a row - spouse, offspring, private property, erotic experiences - even though a millisecond of reflection will bring to mind countless people who have all those things and are still miserable.
