So does art necessarily need to be devoid of any purpose outside of itself? Does art need to be explicitly produced to be intrinsically useless? Or can any object be made into a work of art based on the quality of its design and execution of that design in a tangible medium? Does all art need to be useless, and do all tools, instruments, objects, buildings, machines, etc need to be utilitarian and lack beauty?
And does the motorcycle (or any object) become a work of art simply by placing it in the context of an art and design museum?
