I did a post on the Introduction of James K. A. Smith's new book, Desiring the Kingdom: Worship, Worldview, and Cultural Formation over at my seminary blog. But here let me add this oh-so-true quote:
"Our imaginations get stuck in a rut, and it becomes difficult to get out of them to imagine things differently. When that happens, theoretical dissertations aren't effective in destabilizing these habits of imagination... To jolt the imagination, we need more affective pictures..." (28-29)
Now on p. 30 quoting a book of George Orwell's about an illustrative topic of social class:
"The real secret of class distinctions in the West" can be "summed up in four frightful words" that are often left unuttered: The lower classes smell... "no feeling of like or dislike is quite so fundamental as a physical feeling." Almost every other kind of discrimination could be countered theoretically, with the weapons of facts, ideas, and information, "but physical repulsion cannot."
Smith's books is one of those books that expresses so well the conclusions you have already reached that you read the pages with delight.
