I don't think the world is the way we like to think it is. I don't think it's one solid world, but many, thousands upon thousands of them--as many as there are people--because each person perceives the world in his or her own way; each lives in his or her own world. Sometimes they connect, for a moment, or more rarely, for a lifetime, but mostly we are alone, each living in our own world, suffering our small deaths.
Humanity does not suffer from the disease of wrong beliefs but humanity suffers from the contagious nature of the lack of belief. If you have no magic with you it is not because magic does not exist but it is because you do not believe in it. Even if the sun shines brightly upon your skin every day, if you do not believe in the sunlight, the sunlight for you does not exist.
life's kind of like a painting. A really bizarre, abstract painting. You could look at it and think that all it is, is a blur. And you could continue living your life thinking that all it is, is just a blur. But if you really look at it, really see it, focus on it, and use your imagination, life can become so much more. The painting could be of the sea, the sky, people,buildings, a butterfly on a flower, or anything except the blur you were once convinced it was.
