If we accept that Art imitates Nature, then when attempting to define Art, we must be sure of the intention of the Artist. Was the work created with care of forethought? Or was it whimsically produced by pulling it out of their ass? We can accept that Nature is random, but imitation only occurs with painstakingly deliberate intent. There is nothing accidental about it. If something is Art, the Artist should be able to state the intention of the work from the conceptual stage of the project and should be able to answer what effect the piece is supposed to achieve long before eyes see it or ears hear it. Art may be subjective but it is not arbitrary.
