It can be a work by Mondrian, a piece of music by Schönberg or Mozart, a painting by Leonardo, Barnett Newman or also Jackson Pollock. That's beautiful to me. But also nature. A person can be beautiful as well. And beauty is also defined as 'untouched'. Indeed, that's an ideal: that we humans are untouched and therefore beautiful.
