I'm currently reading (among other things), God in the Wasteland by David Wells. I'm still only partly convinced by his main point, but he has some very good quotes.
We may now have everything, but none of it means anything any more.
We have become TS Eliot's "hollow men," without weight, for whom appearance and image must suffice. Image and appearance assume the functions that character and morality once had. It is now considered better to look good than to be good. The facade is now more important than the substance - and, that being the case, the substance has largely disappeared.
