Art Appreciation

Why do people buy art work that is just a simple dot in the middle of the canvas for millions of dollars? What is the emotion there that people see? Is this painting really worth the million dollars or can you just simple "imitate" this same shape, color and paint?

Intentions of Defining Art

Question: What role does intentionality play in defining art?

Is art something someone intentionally does? Or is it done unintentionally? I believe art is done intentionally for the most part, only people misinterpret some objects as pieces of art when it is accidentally done.
