The term "outsider art", coined and articulated by Roger Cardinal in 1975, has helped the art world understand, and therefore include, many fine artists who would never have been considered legitimate artists. The term "self-taught" is perhaps a broader and more encompassing expression that includes artists who are living mainstream lives, but who were not trained as artists. Great artists produce great art, whether they are trained or simply have a natural gift for expressing themselves through the outlet of their art.
