There is usually agreement that something is a work of art, but what causes this agreement? Is there something objective in the arrangement of the artwork that causes some kind of aesthetic experience in each of us? Or is it entirely a subjective interpretation, hence that only some people will evaluate and understand something as a work of art?
Some opinions:
A: There is nothing in the materials itself that makes something a piece of art. Rather, the spectator gives an interpretation to the materials, conceiving of something as a work of art.
B: It is the internal arrangement of the materials that makes something a work of art. For example, the composition, balance, choice of colours and harmony of the piece is what makes a painting a work of art.
