The positive emotions that arise in...unpromising circumstances demonstrate that social ties and meaningful work are deeply desired, readily improvised, and intensely rewarding. The very structure of our economy and society prevent these goals from being achieved.

Cities have always offered anonymity, variety, and conjunction, qualities best basked in by walking: one does not have to go into the bakery or the fortune-teller's, only to know that one might. A city always contains more than any inhabitant can know, and a great city always makes the unknown and the possible spurs to the imagination.

How will you go about finding that thing the nature of which is totally unknown to you?" (Plato) The things we want are transformative, and we don’t know or only think we know what is on the other side of that transformation. Love, wisdom, grace, inspiration- how do you go about finding these things that are in some ways about extending the boundaries of the self into unknown territory, about becoming someone else?

We fly; we dream in darkness; we devour heaven in bites too small to be measured.

We have only the language for fun and miserable, and maybe we need language for deep and shallow, meaningful and meaningless.

The new architecture and urban design of segregation could be called Calvinist: they reflect a desire to live in a world of predestination rather than chance, to strip the world of its wide-open possibilities and replace them with freedom of choice in the marketplace.

The language of commerce has been engineered to describe the overt purpose of a thing, but cannot encompass fringe benefits or peripheral pleasures. It weighs the obvious against what in its terms are incomprehensible. When I drive from here to there, speed, privacy, control, and safety are easy to claim. When I walk, what happens is more vague, more ambiguous-and in many circumstances much richer. I am out in the world. It's exercise, though not so quantifiably as on a treadmill in a gym with a digital readout.
