When I was young our parish built a new church in the modernist mode. It looks something like a very large egg. I had a high school priest who exalted in the modernism of my new parish church over the "old" (and thereby invalid in his mind) forms of the other catholic churches in the city.
The modernist fanatics have the same mindset of all the "experts" in the arts. The fallacy in their thinking is that new is always superior to old...even if it looks inferior. They never consider that maybe all the best designs have been made. I'm not saying that some future architect, painter, composer, etc. might come up with something brilliant. But we may have exhausted most of the great forms. At any rate I much prefer old (pre-twentieth century) to new in just about any art form you can name.
You are of course right.
This mindset carries over into other fields where it may be even more inappropriate. Thus the campaign slogans about “change,” with no real attention being paid to what type of change is meant. The assumption being that anything new is preferable to anything old.
