Well, as you may know, beauty is the conception of one's ideas about something or idea that give someone a certain emotion about said thing. Really, I would say that beauty is perceived by something if it fits our style or way of thinking/believing/doing/ect. The more something fits to your style, the more you see it as beautiful.
"We gain strength, and courage, and confidence by each experience in which we really stop to look fear in the face...we must do that which we think we cannot." - Eleanor Roosevelt
