If your question is all that important to you then you should take the time to word it more carefully so that it makes more sense when you ask it. And taking the time to use basic good grammar will encourage us to take the time to give you a sincere, helpful answer.

Do you want the definition of a specific style of art painted by a specific artist and his or her possible motivation for creating that specific painting or for working in that specific style?

Generally art is a (product of) human activity, made with the intention of stimulating the human senses as well as the human mind; by transmitting emotions and/or ideas. Beyond this description, there is no general agreed-upon definition of art . It may refer to a wide range of human activities and artifacts, and may be used to cover all or any of the arts, including music, literature and other forms. It is most often used to refer specifically to the visual arts, including mediums such as painting, sculpture, and printmaking. .
The artist you could choose is Marcel Duchamp, He ripped an urinal out of Paris subway and entered it in an art show titled "The Fountain" [1917). He was motivated to show that anything an artist produces or puts on public view should be considered to be art. In doing so, art was never the same again. He opened the door to artworks and installations made up of all manner of things and broadened the conception of what art is today, . The question today isn't "Is it art?", the question is "Is it good art?"
