"Fashion is something barbarous, for it produces innovation without reason and imitation without benefit."

I believe that people who think more deeply about life have better taste. Good taste is unique to the human race... great art, food, music, etc., is a product of our ability to improve upon things we've observed. Good taste is the biproduct of the ability to reason through it.
Most people don't have any taste because they don't think on their own. But great intellects (from mathematicians to archaeologists to botanists to... blah blah...) will agree that Bach and Picasso reach deeply into our souls.
