When Nerdrum says 'Art', he really means modernism, and much of what he writes seems to be a defense of figurative or empathic work in the face of modernism. As interesting as the writings are, I admit that Nerdrum's opinions do ring of positioning. I have a hard time believing that he wholly embraces the ideas put forth. Nerdrum's works do not offer up mere surface imagery. He has his own blend of originality.
Many paintings mix classical imagery and execution with irony and shock-value.
But enough of my words, on to Nerdrum. This would be an error of judgement. Kitsch is not modern art. Going in depth and becoming engrossed is the goal, for in the depiction of nature itself lies the individual expression. Because modernism has conquered art, kitsch is the savior of talent and devotion.
