The naive artist creates for the joy of it. At this level the artist learns skills and techniques, developing a proficiency that allows creative expression in myriad ways. The academic artist adds power to expression through the mastery of craft. This heralds the level of invention. Breaking rules is the order of the day, challenge the boundaries of academic tradition, becoming increasingly adventurous and experimental.
Inventors use academic tradition and skills as a stepping-stone into new frontiers.
Materials and methods that are out of the ordinary are introduced. Now the creator breaks the boundaries. The academic or inspirational foundation remains as a substructure of unconscious thought guiding these creative efforts. There are individuals whose ideas and accomplishments in art and science defy explanation. Genius is arguably the one level that is unexplainable and perhaps unattainable, something that an individual is born with.
