therefore all beauty is subjective.

I'd disagree, to this and your trash point. I think God is within each of us and in everything, but only those who have the eyes to see will witness it. That's what the quote "Beauty Is In The Eye Of The Beholder" means to me. Once we reach a certain level of consciousness, or rather return to our natural consciousness, we can see the God/beauty within everything, including Taco Bell. It doesn't mean that those things have a natural beauty though, since they have been created by people while at lower levels of consciousness.

Some of the art and architecture of those great cathedrals was obviously done by someone quite blessed with vision and purpose. I'd say their consciousness was one with God or near that.

These are personal views of course, the way I have seen and interpreted things, hopefully they are somewhat clear.

I think we are all beautiful within, we are made in the image of God, yet there are some very "ugly" people who have deluded themselves and covered this truth up.
