I want to respond at length about the importance of aesthetics, art, and architecture in any attempt to recapture life on a human scale--a topic inquired about in comments to my last big post. But work prevents me. Until then, here are two articles:
More Roger Scruton, on the topic of "New Urbanist" Leon Krier and his critique of modernist architecture; and
A post on an interesting urban life/peak oil blog outlining why aesthetics cannot be just a matter of taste, including a brief outline of another important personage in the field, Christopher Alexander.
Bonus: I found this discussion between Alexander and the well-regarded modern architect Peter Eisenman to be quite revealing about what the project of modern architecture is. But it takes some digging through a rather aclectic conversation to get to the meat of it.
