To me, John brought out the things that upon reflection make life worth living, those things that are beyond cultural aesthete in terms of archetypal beauty.
The centuries have proven that man is capable of bringing what's inside out into the real world. The seemingly supernatural advances in technology are a great example of the formidable powers of men and women working together. I think we can all get together and work toward a common goal of no more wars, no more killing people, no more judging.
I myself truly believe that John's visions of a brotherhood of man, of everyone working together, feeding and sheltering and not unduly judging others can be made a reality. And if that makes me a hopeless romantic, an insufferable idealist, I far prefer that to the alternative.
Reach within. It all starts with US.
