Roger Scruton on the high cost of ignoring beauty:
And here, it seems to me, is where beauty matters and how. Over time, people establish styles, patterns, and vocabularies which perform, in the building of cities, the same function as good manners between neighbors. A “neighbor,” according to the Anglo-Saxon etymology, is one who “builds nearby.” The buildings that go up in our neighborhood matter to us in just the way that our neighbors matter. They demand our attention, and shape our lives. They can overwhelm us or soothe us; they can be an alien presence or a home. And the function of aesthetic values in the practice of architecture is to ensure that the primary requirement of every building is served—namely, that it should be a fitting member of a community of neighbors. Buildings need to fit in, to stand appropriately side by side; they are subject to the rule of good manners just as much as people are. This is the real reason for the importance of tradition in architecture—that it conveys the kind of practical knowledge that is required by neighborliness.
